The corn planted by the young people in the village does not want to be topdressing and the corn is growing well after one-time fertilization.

In fact, many corn farmers are very concerned about this problem. It is not up to us to decide whether one-time fertilization is feasible or not. Who owns the corn field? It is naturally feasible to apply fertilizer without topdressing at one time. But the effect needs to be said separately.

How much will one-time fertilization reduce the yield of corn?

The corn fertilization method of one-time fertilization instead of topdressing is called "one-time bombardment" by farmers. In fact, corn growers in many places have adopted this fertilization method. This is mainly to save labor and effort, and the time saved is used to work to earn money, which is also very good.

As crops want to grow well, it is inseparable from topdressing, especially corn, which needs a large amount of fertilizer in the later growth process. Topdressing should be carried out in time in order to achieve high yield of corn. According to the growth characteristics of maize, three times of topdressing are generally needed, which are in the seedling stage, trumpet stage and early stage of silking.

Why is it said that the yield of corn will be affected by the bombardment of fertilization?

A bombardment is of course very easy, but the biggest impact of the right and wrong method is the excess fertility of corn in the seedling stage, which is easy to cause the overgrowth of corn, while in the middle stage of corn growth, the soil fertility declines. at this time, the flourishing period of corn growth needs more fertilizer than the seedling stage, at this time, the fertilizer can not keep up with the corn growth is easy to be affected, and affect the late corn fruiting. The reduction in production is also a natural result.

How much corn can be reduced by bombardment?

Relevant statistics show that the use of one-shot fertilization method will generally reduce the yield of one mu of corn by about 7% to 8%, that is, about 200 jin of corn. However, this figure is also very general, which is not necessarily the case. Ordinary people know that the key to a good harvest is God. No matter how good your cornfield is, if God doesn't rain at the corn seedling stage and gives you a few rainstorms at the corn heading stage, it is needless to say about this year's harvest. No matter how much you pursue fat and reduce production, it is certain. Therefore, topdressing does not necessarily lead to high yield. Of course, if there is no topdressing, there is no hope of high yield.

Sometimes it's not a question of how much more corn topdressing costs, the key is that it's a waste of time. All the young labourers in the countryside have gone out to earn money, at least a hundred yuan a day. And now many young people will stop farming the old people in the family. They are too tired. And most of the old people are reluctant not to plant, but they can't keep up with the physical strength of chasing fat several times. Therefore, many of them also use the method of fertilizing with one bombardment.

Rational use of fertilizer

In fact, the method of one-time fertilization does not mean that there are no benefits, choosing the right fertilizer can reduce the loss of non-topdressing in the later stage. Generally in the corn sowing time to choose the appropriate slow-release fertilizer, rather than choose the ordinary ternary compound fertilizer, the effect is still very good. There are many slow-release fertilizers specifically developed for the problem of one-time fertilization. However, when buying fertilizer, you must go to the regular place to buy the slow-release fertilizer produced by regular manufacturers.

The above comes from promoting agriculture through science.
