Planting of high-yield lotus root

Lotus root is a kind of aquatic product that everyone likes to eat. It was cultivated in China more than 3,000 years ago. Now carbonized ancient lotus seeds have been found in Liaoning and Zhejiang, which shows its long history. Here is a brief introduction to the cultivation of high-yield lotus root.

When planting lotus root, we need to have a big enough pond first. In addition to the soil in the pond, there must be enough water to make it grow normally. At the same time, it also has some requirements for the soil in the pond, and only if it can meet its requirements can it grow normally. The soil is best rich in organic matter, ph is relatively neutral, and there are some trace elements inside, if the water quality is too clear, or tap water can not let the lotus root grow normally.

When planting, keep its temperature between 20 ℃. Especially at the beginning of planting, the temperature must be well controlled. If you want to plant at the right temperature, if you plant in the north, you should choose to plant in March and April. Because the temperature in the south is generally higher than that in the north, it should be planted in April and May, a little later than in the north.

In order to meet the demand of fertilizer in the growth process of lotus root, reasonable topdressing should be achieved. Generally, about 5 weeks after planting, when the plant grows a few leaves, it begins to fertilize the lotus root, which can promote the lotus root to branch and produce leaves. When the lotus root field is full of standing leaves, and some lotus root plants have appeared tall leaves, at this time the underground stem of lotus root has entered the lotus root stage, it is necessary to apply lotus root fertilizer in time.

The main disease of lotus root is lotus root rot. In the prevention and control, we should first make a good introduction, select a healthy lotus root with normal color and no damage, and spray 72% methyl topiramate 800 times + Sukeling 800 times solution for 24 hours before sowing. After the diseased plant was found in the field, the disinfection of the whole field was sprayed with 600-fold solution of Jiatuo, and the part of the diseased plant was treated with Kangkuning to prevent spread.

The above are the main points for attention on the cultivation of high-yield lotus root, in planting, to take good care of lotus root, as long as there are no natural disasters, lotus root will generally be high-yielding.
