The cultivation technique of winter grazing 70 rye
Winter 70 rye is a genus of grasses and genus of grasses that grows in most parts of the country. Because it can provide fresh grass for livestock and poultry in winter and spring, but also can harvest seeds, and high yield, excellent quality, is ideal for both grass and grass varieties. I. Characteristics and nutritional value Dongmu 70 rye resembles wheat. Its stalks are thick and tough. The leaves are dark green and broad. The leaf sheaths are purple and velvety. Each ear has 60 to 70 seeds, and the seeds are pale orange and dry. Weight 24 - 26 grams. The winter grazing 70 rye has strong adaptability and elasticity during the sowing period. It can be sowed from late August to mid-December. The early growth is fast, and the cold resistance is strong. The stem and leaves of minus eight degrees Celsius will not be damaged. More tillers, good regenerability, large amount of leaves, soft grass, livestock and poultry like to eat. In mid-and late-May, the seed matures, and the whole growth period is 240-260 days. The seed production performance is good, the maturity is the same, the grain is not shattered, and the output of an acre seed is about 200 kilograms. In late February, it is bubbling 1-2 times. Acre can still harvest 115-155 kg of seeds. Dongmu 70 rye is of good quality and rich in nutrition. The fresh grass contains 5.83% of crude protein, 1.91% of crude fat, 44.61% of nitrogen-free extracts, and good palatability. It is an excellent forage for all types of livestock and poultry. Grain contains 12.6% crude protein, 2.15% crude fat, and 1.79 crude fiber. %, planting an acre of winter grazing 70 rye can harvest 99-102 kilograms of crude protein, the equivalent of 1370-1,430 kilograms of rice, wheat 850-870 kilograms. Second, cultivation techniques A selection of land and sowing: winter grazing 70 rye is not strong resistance to picking, should choose the fertility of higher land cultivation. Planting areas should be deep ploughing, fine-graining, and ploughing. Sowing from September to October is appropriate, with a sowing rate of 4-5 kg ​​per mu and a reduction of 3 kg per mu. Drilling is preferred, and the spacing is 25-30 cm. The arid land can be taken with deep trenches and shallow cover, which is conducive to drought-resistant seedlings. B fertilization and field management: winter grazing 70 rye for fertilizer pasture, fertilization and production have a great relationship. In the site preparation Shizujifei, especially the poor fertility of the land per mu can be applied cow manure 2000-3000 kg of calcium magnesium phosphate fertilizer 40-50 kg. 3 to 5 days after emergence, application of "weaning fertilizer" applies 5-6 kg of urea per acre to re-apply manure, seedlings grow to 4-5 leaves to start tillering, and can apply 10 kg of urea per acre; The quick-acting fertilizer is used to promote regeneration and increase production. In case of drought and winter conditions, it should be promptly irrigated. In the seedling stage, one cultivator cultivator can be used to remove the trash. Remaining in the field during the jointing period, appropriate topdressing of potash fertilizer to prevent falling down, conducive to full grain filling, heading to prevent wheat head blight and smut. C. Use: When the height of the grass layer is about 30 centimeters, it can be used. For example, in mid-September, sowing in mid-November can be grazing or grazing until the end of May. It can be cut 4-5 times and produce more than 5,000 kilograms of fresh grass per acre. Retaining the field can also be cut 1-2 times early, can harvest 1000-2000 kilograms of fresh grass, has little effect on the seed yield, and the height of grazing is 3-5 cm. Fresh grasses should be fed directly or dried hay.
