Selection of seed fertilizer for corn and matters needing attention

Corn is a major food crop in China, which has a very wide range of distribution in the northern region. Fertilization is indispensable when planting corn. Among them, the kind of fertilizer is more important, which is directly related to the yield and growth ability of maize. So how to choose corn fertilizer? How should I use it? What are the points for attention? The following editor will introduce you one by one, let's have a look!

1. Selection of seed and fertilizer

There are many fertilizers available for corn as a kind of fertilizer, but there are also fertilizers that are not suitable for growing fertilizer. For example, potassium chloride, ammonium chloride and so on, these fertilizers will produce a lot of chloride ions. Chloride ion is very disadvantageous to the growth of maize seeds and seedlings. Light hinders the growth of seedlings, while heavy ones produce too much heat, causing the seedlings to burn out. Then there is ammonium bicarbonate, the volatilization of ammonium bicarbonate is very corrosive, which can easily lead to seedling damage. If the proportion of application is more than 2%, there will be poison, fertilizer damage and other bad now. Therefore, corn seed fertilizer is mainly compound fertilizer as far as possible, which can not only ensure the safety of fertilization, but also meet the nutritional needs.

2. How to apply

There are many ways to apply corn seed fertilizer, first of all, you can use the method of seed dressing. First, the biological fertilizer and trace elements and other fertilizers are decomposed and fermented, and then the seeds are sprayed comprehensively and uniformly, and the seeds are generally sprayed to ensure that the seeds receive drugs evenly. Then the seed can also be decomposed into liquid, and then soaked in it for half a day. After it is air-dried, it can be sowed. Finally, it is the most commonly used strip application, hole application and so on, generally based on chemical fertilizer. However, we should pay attention to the seeds do not touch fertilizer, to avoid burning, the depth is controlled at about 12 cm.

3. Benefits of applying seed fertilizer

There are many benefits of corn fertilizer, mainly to meet the nutritional needs of corn in the early stage of growth. It is generally determined according to factors such as soil fertility, and is usually applied on plots with insufficient fertility. The main composition of seed fertilizer is nitrogen and phosphorus fertilizer. And in the high and cold areas, because the ground temperature is relatively low, phosphorus is more and more insufficient, if it is not replenished in time, it will seriously affect the seed germination. Proper phosphate fertilizer can not only increase the emergence rate, but also enhance the ability of disease resistance.

4. Points for attention

When applying seed fertilizer, we must pay attention to the reasonable selection of seed fertilizer varieties. Improper selection of fertilizer not only can not promote the growth of corn, but also lead to toxic and other adverse phenomena. Then we should pay attention to the corresponding supplement according to the phenomenon of element deficiency in the field. If chemical fertilizer is used as a kind of fertilizer, then the amount of fertilizer must be controlled and must not be used too much. To prevent the reduction of seed germination rate, destruction of soil structure and environmental pollution.

The above is a brief introduction to the selection of corn fertilizer and matters needing attention. The application of corn seed fertilizer is very important to the growth of corn, so we must pay more attention to it.
