Post-fertility field post-maize technical advice

At present, corn in the northeast region has gradually entered the tasseling and silking period, and the growth is generally good. However, threats such as droughts and floods and early frosts are still present in the later period. Corn borer, armyworm, and large-spot disease will occur more seriously. To guide local governments to strengthen field management and ensure high yields, the corn expert guidance group of the Ministry of Agriculture put forward technical advice on field management at the later stage of maize growth in Northeast China.

Drainage and drought protection and growth: For the early part of the northeastern China, where there is more rainfall in the early part of the year, and in some areas where there is continuous rainfall, for some low-lying, mountainous and gully land plots, water accumulation in the field should be promptly eliminated to prevent damage. At the same time, pay close attention to weather changes, do a good job in soil moisture monitoring, to prevent serious drought situations that may occur in the later period. In case of signs of “fall hang”, water should be promptly provided to meet crop growth and development needs, and avoid reducing production due to drought.

Supplementary grain fertilizer increased grain weight: Rain easily lead to fertilizer leaching, causing later defermentation. In the silking stage of corn, timely nitrogen fertilizer should be applied in time according to the soil nutrient status and plant growth, and potassium fertilizer should be added appropriately. However, the amount of fertilization should not be too much, the fertilization period should not be too late to prevent late-maturing greediness. In the grain filling stage, foliar spraying of potassium dihydrogen phosphate, urea and other mixed liquor can also be used to promote the accumulation of photosynthate and increase grain weight.

General defense control pest control: corn borer, armyworm, and large spot disease are the major pests and diseases of corn production in Northeast China. The recent high temperature, high humidity, and closed fields can easily lead to aggravation of pests and diseases. We must strengthen monitoring and early warning, carry out prevention and control in due course, vigorously implement green prevention and control technologies such as biological control, light trapping, and sex trapping, and comprehensively use overhead self-propelled mechanical sprays and flying defenses to carry out unified prevention and control. Prevention of colonization. For diseases such as corn leaf spot disease, we must remove diseased plants in time to reduce the sources of pathogenic bacteria.

Promoting early maturing and preventing early frost: Recently, the Central Government issued a subsidy policy to promote early maturing of the comprehensive application of northeastern autumn grain, and given subsidies for the spraying of potassium dihydrogen phosphate and foliar fertilizers on autumn crops sown in cold spring and late evening. The corn expert guidance group and the broad masses of agricultural technicians should work with the local agricultural department to formulate implementation plans as soon as possible, do a good job of policy advocacy, conduct in-depth guidance services in the field, and determine the reasonable spraying agent and spraying dose according to the growth and development of the plants and weather conditions. Spray prevention time, improve the quality of work and implementation of results, and promote safe maturity, to avoid the risk of early frost.

Timely and late harvest of high yield: This year, the sowing date of corn in some areas in the northeast is late than usual, and all regions must delay the corn harvesting time as early as possible. When the loquat leaves are dry and loose, the grains are hardened, the grain cortex is bright, the grouts disappear, and the black layer appears at the base, the harvest is the best to prolong the grain filling time, accelerate the dehydration of the ear and grain, reduce the grain water content, and increase the maize yield. Grain quality.
