Why does lotus root only grow leaves and not lotus root?
The nutritional value of lotus root is obvious to all of us, and now lotus root is grown in many places. A while ago, many people asked why the leaves of the lotus root they planted grew extremely fast, but the lotus roots dug out were very small, which left them very puzzled. So what causes this phenomenon? Is there any way to solve it? Then let's take a look at what Qinnong.com is sharing with everyone today.
Reasons for only growing leaves and not lotus root
1. Improper selection of varieties
If the lotus root you planted only grows leaves and does not grow lotus root, then the first thing you need to do is understand clearly what kind of variety you planted at the time. After all, there are many varieties of lotus root, such as root-producing types, ornamental types and seed-producing types. Different varieties determine how they perform, so if the variety is wrong, then naturally it will not grow lotus root. If the variety you chose is a root-producing type, then the failure to grow lotus root may also be a problem with your planting site. You did not choose a variety suitable for local planting, and this is also one reason affecting its lotus root formation.
2. Improper density
If the planting density is unreasonable, it can also cause lotus root to only grow leaves and not grow lotus root. Although lotus root grows in ponds, it still needs a certain amount of photosynthesis to promote its growth. If the density is too high, the leaves grow very fast, one next to another shading each other, and the permeability between the pond areas is also poor, so it is very normal that the lotus root cannot grow at a normal speed.
3. Water management
The growth of lotus root requires sufficient water, but that does not mean the water in the lotus pond can be very deep. If it is too deep, at best it will slow down the growth of the lotus root, and at worst it will cause various diseases in the whole lotus pond or even drown the lotus root. Next, some people think that since the water does not need to be very deep, then just a little water is enough, or it is enough to keep the soil in the lotus pond moist. If you think that way, then do not expect it to grow big.
4. Improper fertilization
Improper fertilization is actually one of the most important problems causing lotus root to only grow leaves and not grow lotus root, because for many growers, they do not have professional knowledge of lotus root cultivation, nor have they received specialized training, so there will be certain deficiencies in fertilization methods. It may be that partial application of certain fertilizers causes the lotus leaves to grow instantly, but this does not mean the lotus root will also grow.
Solutions
As long as the causes of the problem of lotus root only growing leaves and not growing lotus root are found, then solving it is very simple. First of all, the most basic thing is to choose a good variety, choose a root-producing variety, and then choose seed lotus roots with large tubers and sprouting shoots; the tubers must not have damage or the like before planting. Then when planting, plant according to a reasonable density. Generally, plant one plant about every 60 cm, because it will reproduce and multiply on its own. Also, when planting, the water depth in the pond is best about 15 to 25 cm. If there is rainfall, promptly drain the excess water, and in dry seasons replenish water in time. Finally, carry out scientific fertilization according to the different growth stages of lotus root, and do not apply excessive nitrogen fertilizer.
