Currently, the Northeast region have moved into tasseling corn silking stage, growth overall is better, but still faces late drought, early frost and other threats, corn borer, armyworms, leaf blight, etc. will place emphasis. Localities to strengthen field management guidance to ensure that high-yield harvest, the Ministry of Agriculture Steering Group of Experts raised corn maize growing Northeast late field management technical advice.

(A) drainage and drought insurance growth. More rain for the Northeast early, the recent continuous rainfall in some areas the situation, for some low-lying flood, mountain ditch pond land, water should be excluded from the field, to prevent waterlogging occurs. Also, pay close attention to weather changes, improve soil moisture monitoring, preventing the latter may occur severe drought, such as the case of "Autumn hanging" signs should be timely watering, crop growth and development to meet the demand, resulting in cuts to avoid drought.

(Two) of applied Postheading increased grain weight. Rainy easily lead to leaching of fertilizer, causing late Tuofei. In corn silking stage, should be based on soil nutrient status and plant growth, nitrogen topdressing timely and appropriately increasing potassium. But not too much fertilizer, fertilizing it would not be too late to prevent the greedy green late. Also available in filling stage, spraying potassium dihydrogen phosphate, urea mixture, and promote the accumulation of photosynthetic products, increase grain weight.

(Three) against the ruling system control pests. Corn borer, armyworms, leaf blight is the northeastern region of the main pests of maize production. Recent high temperature, humidity, field canopy, easily lead to increased occurrence of pests. To strengthen the monitoring and early warning, timely carry out prevention, promoting biological control, light trapping, sex pheromone trapping and other green prevention and control technology, and integrated use of self-propelled machinery elevated anti-fly spray and other measures to carry out anti-rule and group Anti Masses. Corn leaf blight and other diseases, but also timely removal of diseased plants, reducing pathogen infection source.

(Four) promote early anti-early frost. Recently, the central government introduced comprehensive Northeast autumn fertilization promoting premature subsidy policy, due to late sowing of autumn cold spring floods crop spraying potassium dihydrogen phosphate, fertilizer and other grant. Corn expert guidance group and the majority of agricultural workers with the local agricultural sector to develop implementation plans as soon as possible, improve policy advocacy, and farms to carry out guidance services, depending on the plant growth and weather conditions, to determine the reasonable spraying agents, dosage and spraying spray defense time and improve quality of operations and implementation of the results, to promote safe mature, to avoid early frost risk.

(Five) wins a timely late harvest yield. Northeastern parts of corn this year than normal and late sowing, early frost before the onset of various localities should try to delay corn harvest time. When dry husk loose grain hardens, grain cortex bright, filling milk line disappears, the base layer is a black harvest for the best, in order to extend grain filling time, acceleration ear and grain dewatering, reduce grain moisture content, maize yield and grain quality.
