The better rain this spring is conducive to the physiological growth of wheat. At present, the growth is generally gratifying. However, in the case of more spring rain, with the rise of temperature, high temperature and high humidity may occur, and rust and powdery mildew may easily occur. In addition, diseases from the beginning of April to the beginning of May are diseases, especially the susceptible strains of Chuandao; In addition, the density of some fields is too large to be susceptible to disease lodging and easy to defertilize. We should strengthen late management for the corresponding situation.
1, prevent lodging: For excessive density of land and high stalk varieties, it is necessary to take active measures to prevent and remedy. In the late wheat period, paclobutrazol should not be sprayed to prevent lodging. The spraying of potassium dihydrogen phosphate, photosynthetic micro-fertilizer, and FA dryland dragon should be the main method to enhance the resistance of wheat and reduce the chance of lodging. The superfluous wheat should be sprayed with superphosphate, potassium dihydrogen phosphate and various compound foliar fertilizers repeatedly to reduce losses.
2, remove weeds: weeds to manually remove the main, remove the weeds after the removal of the field as far as possible, and burn or crush, to avoid grass seeds into the ground, causing the re-growth of weeds in the next year.
3, do a good job of "two insects and three diseases" prevention and treatment: wheat bran is mainly a scab hazard, can be used to control the dimethoate 1000-1500 times. The harm of midge pests is greater, and it is better to control the whole system. It can use 1.5-2.0 kilograms of enemy powder or 1605 powder to prevent and control, and also can use 50% of 1605 powder or 50% of phoxim 2000-3000 times to control, after 5 pm The best spraying effect. Powdery mildew with 25% triadimefon 60-80 grams of water spray 75-80 kg control, scab disease can be used 50% carbendazim or 50% thiophanate-methyl for prevention and treatment.
4, to prevent dry hot wind, premature aging and dry: pouring a good grouting water, wheat yellow water is an effective means to prevent the damage of dry hot wind, but can not be carried out due to the conditions of the foliar spray fertilizer, spray spraying 5-7 days 1 % Potassium dihydrogen phosphate solution or superphosphate solution.
