Pyrey creeping: description, properties, control measures
Probably one of the most famous weeds, with which it is incredibly difficult to fight - the wheatgrass creeping. At the same time, it not only harms people, but also benefits because it is used in traditional medicine, and some supporters of organic nutrition - even in cooking.
Pyrey creeping, which is described below, refers to perennial grass plants of the family Cereal. This name he received thanks to his numerous roots, which grow in different directions, spreading to all new areas of land. What is a wheatgrass creeping? Photos, description of this weed are presented in our article, however, it is familiar to every gardener. Pyraeus grows to 50-120 cm in height. Its knobby, creeping rhizome can reach several meters in length. It is able to penetrate loose soil to a depth of 1 m. Most often, its roots are located in the upper soil layer (5-6 cm from the surface). They almost never penetrate to a depth of more than 15-20 cm.
Elongated leaves have a width of 5-10 mm.Thin veins are clearly visible on them. This polymorphic plant can be either green or bluish, bare or hairy. On long stems, bare spikelets are 10-15 cm long with 4-7 flowers. They have lanceolate scales. Pyraeus creeping blooms in June and July. Weed seeds ripen in late July and early September. This plant is sensitive to drought. During wet periods, it grows literally before our eyes.
This monocotyledonous weed propagates vegetatively (with the help of rhizomes) and sexually (seeds). Both of these methods of spreading wheatgrass are very effective. In large areas, it multiplies with the help of rhizomes, which spread out many meters in different directions. There are about 250 million rhizomatous buds on one hectare of soil covered with grass. Of all of them can grow high-grade plants. At the same time, any piece of roots with a kidney can quickly regenerate a whole weed.
Pyrey creeping cross-pollinated. Due to this peculiarity, it can form new genotypes with increased resistance to adverse conditions. Seeds grains, if necessary, go into a stage of rest. Because of this, they can maintain their germination 10-12 years, germinating with the onset of favorable conditions.The fertility of this weed is extremely high. So, one large plant can produce up to 9-10 thousand grains. Pyraeus creeping samosterilen.
Description of seed grains
The wheatgrass seeds are spindle-shaped, slightly oval-shaped. Their length is 6-10 mm, and the thickness is about 1.25 mm. Grain covered with films. Their top is truncated, slightly rounded, and the base is slightly thickened. The seed color is greyish green with a yellowish tinge. Their surface is hard, covered with small grooves. From their center there are osteous points up to 8 mm in length. The mass of a thousand seeds is only 3-4 g. The weevil cleared of films has an elongated shape. Its rounded tip is covered with small short hairs. Seed length is 4-5 mm, and thickness - about 1 mm. The surface of the seeds is denied by small and shallow wrinkles. Coloring of bare seeds is yellow-brown.
Wheatgrass creepers germinate with the onset of heat in March – May. The optimum temperature for this is only +2 ... + 4 ° С. This weed most rapidly develops at +20 ... + 30 ° С. With the advent of 4-6 leaves, it begins to form a powerful rhizome, which makes it more stable.
Weed is widely distributed throughout the Northern Hemisphere, in areas with a temperate climate. Wheat grass creeping intensively spreads on fertile soils, characterized by a high nitrogen content. The clogged land in spring is completely covered with green leaves of seedlings of this weed. Pyrei creeping is common on coastal meadows, sands, glades, in the steppes, along roadsides, in weedy places. He is a frequent visitor to summer cottages, vegetable gardens and fields. This weed prefers soils rich in humus, loose sand and marsh soils. He chooses enough wet areas. With a significant compaction of the soil, wheatgrass creeps out of the community When plowing land with the help of a plow creates an environment favorable for the development of this weed.
Pyreus creeping, the fight against which is conducted by people constantly, is notable for its high pest damage. So, agronomists have calculated that when only 8-10 of such plants appear in winter wheat crops per 1 square meter, their yield decreases by about 5 quintals per hectare. In addition, the creeping wheat weed has a negative effect on the soil itself.It not only depletes it, absorbing nutrients, but also dries the fertile soil very strongly. Thus, for the formation of 100 kg of seeds per hectare of land, wheat grass uses water 3 times more than winter wheat. For the formation of 6 tons of underground and above-ground mass of this weed per hectare it absorbs up to 69 kg of potassium, 46 kg of nitrogen and 32 kg of phosphorus from the soil.
Grassgrass Control with Herbicides
One of the most dangerous weeds for agricultural land is creeping wheat grass. How to get rid of it with modern means? In recent years, various anti-grass herbicides have been used to control this weed. One of the most effective are drugs that contain a chemical substance - clethodim. For 90-95% of the death of wheatgrass creeping when weediness in 68 plants per square meter, only 1 l of such herbicides per 1 hectare of land is needed.
Other chemicals have lower efficacy. So, when using herbicides based on sethoxydim, 3 l of the drug was required to kill 73% of weeds per 1 hectare. There are substances that process the fields in the spring.For control of wheatgrass creeping in crops of grain crops, the herbicides “Monitor” and “Glyphosphate” are often used. The latter can be made on the field after harvest. Post-emergent herbicides belonging to the group of sulfuronic acids, when used together with plant growth stimulants, significantly increase their effectiveness.
Excellent result in the fight against wheatgrass shows "Roundup". Only in the process of application of this herbicide should be observed recommended precautions. It is sprayed on the surface of leaves and shoots. This drug is absorbed by the plant after 4-6 hours and spreads to all parts of it, including the roots. "Roundup" prevents the synthesis of amino acids, which leads to the death of wheatgrass, which is expressed in the yellowing and drying of the entire weed. After that it can be easily removed from the soil. "Roundup" does not affect other plants (non-cereal) and does not affect the soil, which often leads to germination of wheatgrass seeds in the future. In the ground, it loses its activity and quickly decomposes.
For the mass struggle with this weed plant also use the herbicide "Hurricane".Only this drug should be used in those areas where it is not planned to grow cereal crops in the near future.
Traditional weed control methods
What to do if a creeper appears on the dacha? How to get rid of a weed without using any chemicals? Pyreus creeping, measures to combat which include weeding, digging, cutting, is characterized by increased "vitality". The smallest piece of rhizome with a bud, remaining in the ground, will give rise to the growth of a new weed. In this case, this plant will appear again after a couple of weeks.
This weed can appear in the planting of any crops, but especially often it grows in the summer cottages in the planting of potatoes. To combat it, most often use thorough weeding and hilling. It should be extremely careful to choose the rhizomes of the soil, trying to remove any of their pieces. Thus it is possible to significantly weaken this weed.
The alternation of cultivated plants adversely affects creeping grass. Especially detrimental to it act broadleaf plants, shading the soil.These include buckwheat, hemp, lentils, peas, beans, beans, sunflower. To reduce the number of weeds, agronomists use a three-field crop rotation.
A very effective method of dealing with wheatgrass creeping is considered to be its deep embedding into the soil when digging or plowing a plot. At the same time, this plant germinates poorly. When tilling the soil in other ways, rhizomes removed from it are sent to where they can dry quickly and lose their ability to regenerate.
When dealing with this weed, one should not forget that its seeds are notable for their increased resistance to adverse conditions. The main mistake of novice gardeners is that they often leave the torn out plants with nearly ripe ears on the ground. This weed is able to multiply even from those seeds that ripen right on the torn stems already in the garden or in the compost heap. That is why it is better to remove the creeping grass in those places of the plot from which it will not be able to get to the garden again. You can also burn dried weeds.
There is also a method of depleting such plants by depressing crops (most often by sowing herbs). But this method of dealing with wheatgrass is more suitable for gardens, not gardens.Also often used is autumn sowing of oats or wheat in a place free from vegetable crops. When the grasses reach a height of 15-20 cm, the plot is dug up to the depth of the spade bayonet, carefully turning over the layer of soil. Some gardeners sow such areas with oats again, after which they again dig up the soil. Thus, you can quickly get rid of the most overgrown with grass grass.
Pyrei creeping in traditional medicine
Despite its harmfulness to the soil and the crop, this weed can bring benefits to humans. As a drug, use juice, napara, infusions and decoctions of this herb. Pyrei creeping, the healing properties of which have long been confirmed by traditional medicine, have been used for centuries as a medicine. The most commonly used dried rhizomes of this weed. They are used as a blood-purifying agent for the treatment of diseases of the urinary organs and the respiratory tract. This plant has expectorant, diaphoretic, anti-inflammatory, antiseptic and tonic properties. Pyrei creeping, whose properties are due to its chemical composition, is used as an enveloping, hemostatic and laxative remedy.Its rhizomes contain such beneficial substances: saponins, organic acids, vitamin C, carotene, mucus, essential oils, pectins, vegetable proteins, polysaccharides. They have such micro-and macronutrients as iron, calcium, sodium.
Preparations prepared from creeping wheatgrass roots are used for urolithiasis and gallstone diseases, inflammations of the gastrointestinal tract (enteritis, gastritis, colitis). They help with rheumatism, gout, colds, bronchitis and tracheitis. Preparations from the rhizomes of this weed perfectly tone up the skin and contribute to the normalization of metabolism. Outwardly, wheatgrass infusion is used for bathing, for lotions with furunculosis and other skin diseases. As an enema, it is used for hemorrhoids, chronic constipation and intestinal inflammation. In the broth of this grass bathe small children during diathesis.
How is creeping wheat grass? Photos, descriptions of various instances of this plant were presented in this material. It must be said that its species differ somewhat, since the plant is polymorphic, but they are all equally valuable as a medicinal raw material.Its rhizomes are harvested in spring and autumn. You can also use weeds removed from the garden. Dug out rhizomes shake off the ground and washed with running cold water. The raw materials prepared in this way are placed in the sun in windy weather. After the rhizomes are slightly dried up, they are dried in a dryer or in a shaded place. Such medicinal raw materials are stored for no more than 2 years in linen bags or wooden boxes.
Pyrei creeping as a fodder grass
This weed is an excellent feed for all types of livestock and animals. It is well eaten on pastures from the beginning of the growing season to the earing period. Thanks to its nutritional value, wheatgrass has a beneficial effect on weight gain in domestic animals and livestock. Dried creeping wheatgrass is valued as the most nutritious hay. It is much better than virgin grass. It contains more nitrogen (1.53%) than in timothy or ryegrass. Wheatgrass with tall stems is especially appreciated.
Wheatgrass rhizomes are used as valuable succulent feed for horses. Thanks to the nutrients contained in this grass weed, their wool becomes shiny and smooth, and the animals themselves become more resilient.
Weed hybrids with cereals
For many years, Soviet breeders have carried out breeding work aimed at creating a hybrid of wheatgrass creeping with cereals. The plants obtained from crossing with wheat were supposed to combine the grain value and the many years of weed. All these experiments with time have sunk into oblivion. But despite this, Soviet scientists still managed to create wheatgrass-wheat and wheatgrass-rye hybrids with unique properties: frost resistance, resistance to cereal diseases, drought tolerance. It is possible that over time these experiments will be resumed.
