How to top-dress corn?

If the corn's top-dressing and watering work is not done well, the soil will grow more and more lean, and the more species the more compacted, the direct result will be reduced planting output and increased costs. Therefore, we should do a good job of watering fertilizer for corn:

First of all, the application of basal fertilizer, basal fertilizer (based on farmyard fertilizers) has the following advantages: increase the content of organic matter in the soil and enhance the structure of the soil pellets, farmyard manure is best treated with professional fermentation agents, such as the Fertilizer Fermentation dose, can not When there is fertilizer, it will be followed by water. In the seedling stage before the jointing of corn, if it is not based on the actual conditions such as the degree of drought, good or bad conditions, and the condition of the seedlings, timely and appropriate top-dressing and watering will often result in corn on the ground. Some of the seedlings are long and the underground part of the seedlings is difficult to lower, which causes the corn to lose the opportunity for seedlings to nurse, thus laying down hidden troubles for the corn plants. The top-dressing and watering during corn filling period not only increases the investment in corn production, but also wastes fertilizer. At the same time, it also causes late-maturing corn glutinous rice, and even causes frost and other adverse consequences.

Secondly, after top-dressing and heading without top-dressing, the majority of plots are underutilized or the quality of base fertilizers is not high enough to substantially deplete the fertilizer. The nutrients in the soil can no longer meet the needs of later growth and development of maize. High-quality and high-yield corn must be treated with some quick-acting nitrogen fertilizers to prevent premature corn aging, promote corn filling and grain filling, and increase grain weight. This time, the “grape attacking fertilizer” cannot only be saved, but it is necessary to apply it early, apply acupuncture points, and apply in appropriate amounts. It can also apply 1-2 kilograms of gold treasure microbial fertilizer products, increase production and increase income, enhance resistance, and increase economic efficiency.

Finally, in the process of growth and development of corn, it not only needs a large amount of fertilizer such as nitrogen, phosphorus and potassium, but also trace elements and other trace elements. In the growth and development process of corn, although the demand is small, but it is not trivial, we took zinc fertilizer. Some experiments showed that the appropriate amount of zinc fertilizer was applied to corn, and the number of grains per spike increased by 50 to 80 grains compared to the control, and the grain weight increased by 15 ~ 30 grams, generally 8% ~ 15% of corn per acre. Such as the application of Golden Baby to promote the growth of spiritual products, can improve product quality, increase production and increase income, effectively prevent various types of deficiency syndrome.
