How to fertilize the newly planted Zizania caduciflora

Zizania caduciflora is a common vegetable in our life, and it is welcomed by many people in our country. When planting Zizania caduciflora, management is very important. Especially fertilization, because fertilizer is the key way to provide growth nutrition for Zizania caduciflora. When applying fertilizer, we should not only apply sufficient base fertilizer, but also do a good job of topdressing. So how to fertilize Zizania caduciflora? Let's take a look at it with the editor.

1. Topdressing for the first time

Zizania caduciflora should be fertilized about three times during the whole growth period. The first time should be carried out about two weeks after transplanting of Zizania caduciflora. At this time, a fertilizer should be applied to promote seedlings. Promote the growth of Zizania latifolia seedlings, so that it can tiller early, which is also known as seedling fertilizer, which is very critical to the growth of Zizania latifolia seedlings. The fertilizer for raising seedlings is mainly ammonium bicarbonate or urea, if it is ammonium bicarbonate, then topdressing about 50 jin per mu, if it is urea, then 5kg can. If the basic fertilizer is sufficient and the growth of Zizania caduciflora is good, then the fertilizer can not be applied this time.

2. The second topdressing

Then the second topdressing work was carried out at the tillering stage of Zizania latifolia. If the leaves of Zizania caduciflora are dim and the number of seedlings in each hole does not exceed 15 seedlings at the peak of tillering, then the long and coarse fertilizer should be applied once. Ammonium bicarbonate, urea or farm manure can also be applied. If the situation is on the contrary, then long and coarse fertilizer can not be applied. However, it should be noted that if there is no topdressing, then the time of the second topdressing should be appropriately earlier, about half a month after planting.

3. Topdressing for the third time

The third topdressing work should be carried out at the stage of Zizania caduciflora. At this time, it is necessary to appropriately increase the amount of topdressing, so as to increase the yield. In the middle of the growth of Zizania caduciflora, it is necessary to ensure that the plant can grow stably, and if the growth is relatively poor and there are more yellow leaves, then topdressing should be done in time. Usually, the time for topdressing should be around the Mid-Autumn Festival, when even Zizania latifolia is gradually tillering and begins to become pregnant.

When the stem begins to change from round to flat, and the number of Zizania caduciflora seedlings that begin to grow to two leaves reaches about 30%. It is the best time for topdressing fertilizer of Zizania caduciflora. Urea, potassium dihydrogen phosphate or ammonium bicarbonate are the main fertilizers. We should pay attention to control the fertilization time, if the fertilization time is too early, and Zizania caduciflora did not begin to pregnancy, then it is easy to lead to the overgrowth of Zizania caduciflora, resulting in the delay of pregnancy time. If the time of topdressing is too late, then the nutrition of Zizania latifolia is insufficient, resulting in a decline in yield, so we must pay more attention to it.

The above is a brief introduction to how to top fertilize Zizania caduciflora. That's all for today's introduction. This article is for reference only. I hope it can help you all.
