Cultivation techniques of Barley with Cell mulching Agent

Barley belongs to Gramineae herbs, beer barley and feed barley points. It is an important raw material for making beer, caramel and feed. When the coating agent is used in barley cultivation, attention should be paid to the coordination with other scientific and technological measures to increase production, and the following technical points should be mastered: 1. Selection of improved varieties: Select improved varieties according to their uses; if they are mainly feed, V06, V24, V013 can be selected. 2. Seed pre-sowing treatment: ① sunning seeds, spreading them for 1~2 days before sowing;② selecting seeds, using winnowing, screening or muddy water to select seeds, removing impurities, shriveled seeds and diseased seeds, and selecting seeds with large and full seeds;③ seed disinfection, preventing smut and stripe disease, soaking seeds with lime water or soaking seeds with 2g carbendazim or equivalent thiophane methyl per kilogram of seeds; ④ Soaking seeds for germination can be combined with muddy water seed selection and seed disinfection. Soaking seeds can be dried for 48 hours before sowing. Third, do a good job of seed dressing: 10~12 kg of selected seeds per mu, after pre-sowing treatment, 1.0~1.5 kg (2~3 bags) of seed dressing: put barley seeds into containers or plastic bags, pour liquid agent and fully stir, and then sprinkle powder while mixing, so that the seed surface can be evenly adhered to the powder after sowing. It should be mixed and sown immediately. It is strictly prohibited to sow overnight after seed mixing. 4. Reasonable dense planting, improve sowing quality, divide moisture and drill sowing, evenly cover soil, ensure 200 ~ 250 thousand basic seedlings, 350 ~ 400 thousand effective ears, 30~40 full grains per ear, 36~40 grams of 1000-grain weight is ideal. V. Scientific fertilization: actively promote barley balanced fertilization technology, nitrogen, phosphorus, potassium and boron fertilizer combination: apply 1000~1500 kg farm manure per mu as base fertilizer in medium fertility fields, the total amount of urine literacy per mu is 20~30 kg, calcium phosphate is 30 kg, potassium fertilizer is 5~10 kg, borax is 1 kg. Phosphorus and boron fertilizer as base fertilizer, urea 1/3 as seed fertilizer, 2/3 as tillering fertilizer and jointing fertilizer. VI. Timely irrigation: barley root system is shallow, and excessive drought and waterlogging are not conducive to root growth. It is necessary to timely irrigate seedling emergence, tillering, jointing, booting, heading and grouting water, so as to achieve rapid irrigation and rapid drainage. VII. Strengthen the prevention and control of diseases, insect pests and weeds, do a good job in wheat field elimination, reduce weed damage, pay attention to the prevention and control of smut, stripe disease and wheat aphid. Through the above aspects of work, as long as the technology is in place, standardized planting, scientific management, can create high yield.
