Why does the lotus root grow only leaves but not lotus roots

The nutritional value of lotus root is obvious to all, but now lotus root is planted in many places. Some time ago, many people asked why the leaves of the planted lotus root grow very fast, but the lotus root dug up is very small. This makes them very confused, so what is the reason for this phenomenon? Is there any solution? So let's take a look at the content shared by the pro-agriculture network to you today.

The reason why only leaves grow but not lotus roots grow

1. Improper seed selection

If the lotus root you plant has only long leaves but no lotus root, then the first thing you need to know is what kind of lotus root you planted at that time. After all, there are many lotus root varieties, such as long lotus root type, ornamental type and long lotus type. Different varieties also determine its form of expression. If the variety is wrong, then naturally it will not grow lotus root. If you choose the long lotus root type, then if you do not grow the lotus root, you will still have the problem that you are the planting place, and you have not chosen the breed of face dog that is suitable for local planting, which is also one of the reasons that affect its growing lotus root.

2. Improper density

If the planting density is unreasonable, then it will also cause the situation that the lotus root grows only leaves but not lotus root. Although the lotus root grows in the pond, it still needs to carry out a certain amount of photosynthesis in order to promote its growth, and the density is too high. The leaves grow very fast, one by one next to each other sunshade, so the permeability between the ponds is not good, so it is normal that the lotus root can not grow at a normal rate.

3. Water management

The growth of lotus root requires sufficient water, but it does not mean that the water in the lotus root pond can be very deep. If it is too deep and light, it will slow down the growth of lotus root, and heavy will lead to all kinds of diseases or even drowning of the whole lotus root pond. Secondly, some people think that since they do not need very deep water, as long as they have a little water or keep the soil moist in the lotus root pond, if you think so, then you do not want it to grow up.

4. Improper fertilization

In fact, improper fertilization is one of the most important problems that cause lotus roots to grow only leaves but not lotus roots, because for many growers, they do not have the professional knowledge to grow lotus roots and have not received special training. therefore, there will be some defects in the method of fertilization, which may lead to the instantaneous growth of lotus leaves due to the partial application of certain fertilizers, but this does not mean that the lotus roots will also grow.

Solution method

The problem that lotus roots grow only leaves but not lotus roots is very easy to solve as long as we find out the cause of this phenomenon. First of all, the most basic thing is to select a good variety, choose the variety of long lotus root, and then choose the root of lotus root with large tuber and sprouting seedlings, and the seeds that can not be damaged above the tuber. Then plant according to a reasonable density when planting, usually one plant is planted every 60 centimeters or so, because it will reproduce on its own. In addition, when planting, the water depth in the pond should be about 15 to 25 centimeters. If there is rain, the excess water should be discharged in time, and the water should be replenished in time in the dry season. Finally, according to the different growth periods of lotus root to carry out scientific fertilization, not partial application of nitrogen fertilizer.
