First, draw hoe repression, increased soil temperature promote early-onset Early spring favorable opportunity to draw hoe "Slush period", that is, when "topsoil" thaw began two centimeters draw hoe, then the best soil moisture, and is conducive to turning green wheat early, early hair roots, and promote seedling. Night wheat fields 1st draw hoe to light, to prevent damage roots and seedlings Ke La press; in saline soil to Wheat "Slush period" and the time after the rain draw hoe, salts to inhibit reversion and reduce the dead seedling; sown deep wheat fields, turning green in time to clear the ridge and soil back clear trees, the tillering node shallow, warm to Liti, increased tiller, hair roots. Wang Miao and the long wheat field should be deep-rooted in the period of getting up, and the depth of the sputum is about 10 cm, in order to break the old roots, spray new roots, and become a strong seedling. In the early spring, the first stroke should be appropriate. Afterwards, the temperature will gradually increase, and the stroke will gradually deepen to facilitate the root system. Strive for 3 to 4 times before the festival. Spring repression should be tailored to local conditions, so that "three pressures and three pressures." The "three pressures" means: the suppression of the roughing of the whole land, and the suppression of the wheat fields; the dry wheat fields without the irrigated conditions are suppressed after the soil has been frozen; the growth of the over-expanded wheat fields before and after the rising period. "Three no pressure" means: no pressure on frosty wheat fields; no pressure on saline-alkali wheat fields; no pressure on soil wet wheat fields. In addition, the suppression should be combined with the slashing, generally it is first pressed and then smashed, in order to achieve the effect of the upper Panasonic, the rafting and the warming. Second, comprehensive prevention and control of pests and diseases Wheat powdery mildew, rust, every 1/15 hectare (1 mu) with 20% rusting emulsifiable concentrate 50 grams, or 15% wettable powder 75 grams, 60-70 kilograms of water, spray prevention at the beginning of the disease; wheat total etch, It can be used with 100% of rusting emulsifiable concentrate 100g per 1/15 hectare, or 15g of 15% rusting WP, 50~80kg of water, sprayed in the ridge of wheat during the period from the rise of the wheat to the jointing stage; At the beginning of jointing, every 1/15 hectare is used with 5% of Jinggangmycin water 100-150 ml, 50-70 kg of water, sprayed on the base of wheat stem. For the prevention and control of wheat bran, it can be used with 50% of èšœ èšœ å¯ wettable powder per 1/15 hectare and 50-60 kg of water. For the control of wheat spiders, use 40% omethoate 25 ml per 1/15 hectare, or 20% dicofol at 50 ml per 1 / 15 hectares, spray 30-40 kg of water to prevent and cure the gray planthopper, prevent the dwarf disease . In addition, attention should be paid to the prevention and control of wheat yellow dwarf disease, bush dwarf disease, wheat leaf bee and underground pests. Application of herbicides controlling weed, currently used herbicides 2,4-D, MCPA, stars, benzene yellow Long, Puma, sigma like. Hummer and Shima can be used to control wild oats and most other monocotyledonous weeds. Among them, Shima is used in wheat fields to control grass weeds. When stems and leaves are treated, it can also remove some broad-leaved hybrids such as sorghum and leeks. Grass; superstar, dimethyltetrachloride, 2,4-butyl butyl ester, benzodiazepine, etc. can be used to control dicotyledonous broadleaf weeds. In the spring wheat field weeds are mainly broadleaf, should choose superstars, benzodiazepines, etc.; for wild oats and other monocotyledonous weeds and broadleaf weeds in the wheat field, in the tetramethyl chloride or superstar liquid The addition of 6.9% Hummer EC 60 ml per 1/15 hectare can prevent two types of weeds. The period of use of the herbicide is generally in the green to the beginning. Strictly follow the instructions for use to avoid phytotoxicity.
