First, the transplanting of corn seedlings is not affected by the spring drought, and it is suitable for early sowing. Through concentrated nursery and concentrated fertilizer management, it is not restricted by the spring drought and drought, cultivate strong seedlings, lay a good foundation for achieving high yield and stable yield of corn, and ensure seedlings, Miaoqi, Miaoyun and Miaozhuang. The seedlings are well-nourished and the roots are developed and robust, which is good for absorbing nutrients and water, promoting the growth of the seedlings and lodging resistance.
Second, we can make full use of the growing season and prolong the growth period of corn. We can stagger the busy farming, plant early, and strive for time, which is conducive to interplanting and increase the multiple cropping index.
Third, the corn roots are deep, the seedlings are strong, the stalks are short, and the directional transplanting can make the leaves orderly, the spatial distribution is even, and the light energy can be fully utilized, so it can be more than 500-1000 plants per mu, and the density is 5000. .
Fourth, seedling transplanting can save the use of seeds, only 0.8-1.5 kg of seeds per acre field, 0.2-1 kg less than the live broadcast, reducing production costs.
