Zhaoyou 5431 is more resistant. Its plant height is about 117 cm, which is relatively strong, and it can ensure the effect of high and stable yield, fertilizer resistance and lodging resistance.

1. Sowing and cultivating strong seedlings at the right time. Usually from early April to mid-May. Suitable application of seedling field fertilizer, seedlings from one leaf to two leaves in the period of spraying appropriate amount of paclobutrazol to cultivate strong seedlings.

two。 Transplanting in time, reasonable close planting: the seedling age is 25-35 days. It is recommended to plant plants with wide rows and narrow rows, with row spacing of 4x9 inch or 5x8 inch, and 5-6 seedlings per hole (including tiller fertilizer), that is, 15-17 000 holes per mu and 80 000 basic seedlings.

3. Scientific fertilizer and water management: apply sufficient base fertilizer and increase phosphorus and potassium fertilizer. Fertilization to achieve the front weight, middle control (especially to control the amount of nitrogen fertilizer), after supplement. Generally, 45% compound fertilizer 25 kg, ammonium bicarbonate 15-25 kg per mu, topdressing 5 kg urea within 7 days of transplanting, 7.5 kg potash fertilizer, planting seedlings in shallow water, living plants in an inch of water, tillering in thin water, heading in deep water, timely drying, preserving water and raising flowers, dry and strong seeds, the combination has larger ears, a relatively long filling period, and should not be cut off prematurely in the later stage, and should be short of water for 5-6 days in the mature period to keep the field moist to maturity.
