How to fertilize Zizania caduciflora

Zizania latifolia is a common vegetable in our life and is welcomed by many people in our country. When planting Zizania latifolia, management is very important. Fertilization is especially important, as it is a key way to provide nutrients for the growth of Zizania latifolia. When fertilizing, we should not only apply sufficient base fertilizer, but also do a good job of topdressing. So how do you plant white rice? Let's take a look at it together with Xiaobian below!

1. The first topdressing

Zizania latifolia should be topdressed about three times during the whole growth period. The first time should be carried out about two weeks after transplanting Zizania latifolia, at this time to apply a fertilizer to promote seedlings. Promote the growth of Zizania latifolia seedlings, so that they can produce tillers early, which is also known as raising seedling fertilizer, which is very critical for the growth of Zizania latifolia seedlings. The fertilizer for raising seedling fertilizer is mainly ammonium bicarbonate or urea. If ammonium bicarbonate is used, then about 50 jin per mu shall be applied, and if urea is used, then 5kg shall be applied. If the base fertilizer is sufficient and the growth of Zizania latifolia is good, then the fertilizer can not be chased this time.

2. Second topdressing

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

3. Third topdressing

The third topdressing should be carried out at the time of Zizania latifolia fruiting. At this time, the amount of topdressing should be appropriately increased to increase yield. In the middle of Zizania latifolia growth, to ensure that the plant can grow steadily, if the growth is relatively poor and yellow leaves are more, then timely topdressing. Usually its topdressing time should be carried out around the Mid-Autumn Festival, because at this time even the new rice is gradually tillering and beginning to be pregnant.

When the culm began to become flat from round and the leaves began to grow to two, the number of Zizania latifolia seedlings reached about 30%. It is the best time for topdressing of pregnant rice fertilizer, topdressing fertilizer is mainly urea, potassium dihydrogen phosphate or ammonium bicarbonate. Attention should be paid to controlling the fertilization time. If the fertilization time is too early and the Zizania latifolia does not start to be pregnant, it is easy to cause the Zizania latifolia to grow long and delay the pregnancy time. If the topdressing time is too late, then the pregnant rice nutrition is insufficient, resulting in a decline in yield, so everyone must pay more attention.

The above is a simple introduction to how to plant Zizania latifolia topdressing. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
