Technical guidance for Huangqiuhai summer maize against drought and drought protection

Since June, most of the Huanghuaihai area has less precipitation, and it has continued to heat up in July, and the drought has developed rapidly in some areas. At present, the yellow-yellow sea summer corn is in the big bell stage, and some enter the silking period of the tassel, which is the most sensitive period of water demand and water shortage. In response to the adverse effects of the continuous development of drought on the growth and development of summer maize, the Ministry of Agriculture organized experts to formulate technical guidance for the anti-frozen and autumn-fed grain technology of Huanghuaihai summer maize, and proposed to "scientific drought resistance, classification guidance, fertilizer and water attack, disease prevention and control "To focus on, strengthen field management and minimize disaster losses."

(1) Expanding the drought-resistant water source so that it can be poured. At present, the yellow-yellow sea corn is in the critical period of male and female ear development. The corn plant has increased water demand, and the drought will cause the number of effective filaments and the number of grains to decrease, which will also cause difficulty in tasseling and form a “ka neck drought”. It is necessary to overcome the luck of relying on rain in the sky, make full use of all drought-resistant water sources, open trenches and ditches, drill wells, raise water, speed up watering, expand irrigation area, and strive to be able to pour a ridge into a ridge and can pour an acre. It is an acre. At the same time, according to the actual situation, water-saving technologies such as sprinkler irrigation, furrow irrigation, sectional irrigation, small-scale irrigation, pipeline water delivery, and alternate furrow irrigation are adopted to improve water utilization and reduce the adverse effects of high temperature and drought on corn.

(2) Due to the reasons for the use of the seedlings, the classification management should be done well. In the allocation of water resources, it is necessary to allocate limited water sources to medium and high-yield fields with good preservation effect and large production potential. For different plots of seedlings, it is necessary to first grow the corn to the big bell stage, and then fill the corn with loose powder or before and after jointing. In the tight water area of ​​Gangpo hills, it can reduce the evaporation of ground water and prolong the drought tolerance time of maize by rowing and protecting. The artificially pollinated corn has been artificially pollinated to reduce the effect of high temperature on the seed setting rate. For areas that have not yet formed an agricultural drought, prepare for various droughts as soon as possible, and replant and replant the severely damaged land in time to make up for the disaster losses.

(3) Both fertilizer and water attack, promote growth and development. For irrigated plots, shallow cultivating should be carried out after irrigating, and soil surface capillaries should be cut to reduce evaporation of water in the field. In areas where precipitation has recently occurred, it is necessary to apply panicle fertilizer in time, and apply 15-20 kg of urea per acre to promote rapid growth of corn. For plots where the drought has not been relieved, it is necessary to spray foliar fertilizer, 800-1000 times of potassium dihydrogen phosphate or 500-000 times of dry land dragon to cool and humidify, and improve the drought resistance of the plants. For plots with delayed growth and weak seedlings, urea should be added to accelerate the fertility process.

(4) Preventing and controlling diseases and reducing damages. Wet sick, dry insects. Sustained high temperature and drought, easily lead to the occurrence of armyworms, mites, corn borers and so on. According to the information on pests and diseases issued by the plant protection department, emergency prevention and control should be carried out in a timely manner. Scientifically grasp the timing and dosage of the drug, and use it in the morning and evening, increase the frequency of application, reduce the concentration of the drug, and avoid the occurrence of phytotoxicity. To choose a pyrethroid, organophosphorus or insect growth regulator insecticide spray, or use phoxim, chlorpyrifos or Bt granules to apply to the corn bell mouth. Where conditions permit, take preventive and flying defense operations to improve the efficiency of prevention and control. In areas with sufficient rain and good sensation, attention should be paid to the prevention and treatment of diseases such as dwarf disease, rough disease, and leaf blight.

Sticky Rice

Glutinous rice is the hulled rice of glutinous rice, which is mainly produced in southern my country. It is rich in nutrients and contains protein, fat, sugar, calcium, phosphorus, iron, vitamin B1, vitamin B2, niacin and starch. It is a warm tonic and strong food, and has a certain relief effect on poor appetite, abdominal distension and diarrhea. It has the effects of relieving frequent urination, invigorating the spleen and warming the stomach, and invigorating the middle and benefiting qi. At the same time, glutinous rice is sticky and difficult to digest. After eating too many greasy dishes, you should avoid eating a lot of glutinous rice.
