A Detailed Guide to the Latest Topdressing Methods for Water Bamboo Cultivation

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

1. First topdressing

Throughout the entire growth period, water bamboo should be topdressed about three times. The first should be carried out about two weeks after transplanting water bamboo, at which time a seedling-promoting fertilizer should be applied. This promotes the growth of water bamboo seedlings and enables them to tiller early. It is also called the seedling-lifting fertilizer and is very critical to 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

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 a thickening fertilizer should be applied once. Ammonium bicarbonate, urea, or farmyard manure can likewise be applied. If the situation is the opposite, then the thickening fertilizer can also be skipped. However, note that if the seedling-lifting fertilizer was not applied, then the second topdressing should be appropriately moved earlier, applied about half a month after planting.

3. Third topdressing

The third topdressing should be carried out during the fruiting stage of water bamboo. At this time, the topdressing amount should be appropriately increased in order to raise the yield. In the mid-growth stage 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 the 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 the swollen stem.

When the stems begin to change from round to flat and the number of water bamboo seedlings whose leaves begin to grow toward both sides reaches about 30%. This is the best period for applying the swollen-stem fertilizer. The topdressing fertilizers are mainly urea, monopotassium 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 the swollen stem, then it is easy to cause excessive vegetative growth of the water bamboo, leading to a delay in the swollen-stem formation time. And if the topdressing time is too late, then the nutrition for swollen-stem formation will be insufficient, leading to a decline in yield, so everyone must pay close attention.
