How to carry out topdressing during the cultivation of water bamboo

Water bamboo is a fairly common vegetable in our daily lives, and it is very popular among many people in China. When growing water bamboo, management work is very important. This is especially true for fertilization, because fertilizer is a key way to provide growing nutrients for water bamboo. When fertilizing, we should not only apply sufficient base fertilizer, but also do a good job of topdressing. So how should water bamboo be topdressed? Let's take a look together below!

1. First topdressing

During the entire growth period of water bamboo, topdressing should be done about three times. The first time should be carried out about two weeks after transplanting the water bamboo; at this time, a seedling-promoting fertilizer should be applied once. This promotes the growth of water bamboo seedlings and enables them to tiller early, and it is also called the seedling-lifting fertilizer, which is very crucial for the growth of water bamboo seedlings. The seedling-lifting fertilizer is mainly ammonium bicarbonate or urea. If it is ammonium bicarbonate, then apply about 50 jin per mu; if it is urea, then 5 kg is enough. If the base fertilizer is sufficient and the water bamboo is growing well, then this fertilization can be skipped.

2. Second topdressing

Then carry out the second topdressing during the tillering stage of water bamboo. At the peak tillering stage of water bamboo, if the leaves are dull and the number of seedlings per hill does not exceed 15 seedlings, then apply a thickening fertilizer once. Likewise, ammonium bicarbonate, urea or farmyard manure can also be applied. If the situation is the opposite, then the thickening fertilizer can also be omitted. However, it should be noted that if the seedling-lifting fertilizer was not applied, then the second topdressing time should be appropriately advanced, and applied about half a month after planting.

3. Third topdressing

The third topdressing should be carried out during the shoot-forming stage of water bamboo. At this time, the topdressing amount should be appropriately increased in order to raise the yield. In the mid-growth period of water bamboo, it is necessary to ensure that the plants can grow steadily. If the growth is relatively poor and there are many yellow leaves, then topdressing should be carried out in time. Usually its topdressing time should be around the Mid-Autumn Festival, because at this time even the new water bamboo has gradually tillered and begun to form shoots.

When the number of water bamboo seedlings whose stems begin to change from round to flat and whose leaves begin to grow in two directions reaches about 30%. This is the best period for applying the shoot-forming fertilizer, and the 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 water bamboo has not yet begun to form shoots, then it is easy to cause excessive vegetative growth of water bamboo and delay the shoot-forming time. And if the topdressing time is too late, then the nutrients for shoot formation will be insufficient, resulting in a decrease in yield, so everyone must pay close attention.

The above is a brief introduction to how to topdress when growing water bamboo. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
