Seed selection and seed retention techniques of Lotus Root

Lotus root is a vegetable crop of Nymphaeaceae, which is loved by many people in our country. Lotus root is rich in nutrients, which can not only be fried, but also eaten raw. And the non-staple food and all kinds of snacks processed by lotus root are very popular. Now the planting area of lotus root is relatively wide, and the most important thing when planting lotus root is to select and retain seeds. So the editor brings you the technology of selecting and leaving seeds of lotus root today. let's have a look!

1. Seed selection technology

Asexual selection

The planting area of lotus root in our country is very extensive, and there are many varieties of lotus root in our country. Therefore, asexual seed selection has become the main seed selection method of lotus root. For example, the varieties cultivated from the excellent series of clones in recent years are Zhe Hu 1 good, Kexuan 1 and so on. Asexual seed selection mainly depends on planting some high-quality individual plants with high yield, good quality, strong growth ability and low incidence of disease, and then transport them to the relevant local agricultural departments. Research and asexual reproduction are conducted by professionals, and then promoted.

Sexual hybridization

Sexual hybridization is a method to study new varieties of lotus root, which has also been applied to lotus root breeding in our country. Sexual hybridization can effectively combine the different good qualities of parents and cultivate high-quality varieties with high yield, good quality and early and late maturity. In fact, it is not much different from asexual seed selection, but skilled growers can do it on their own. At present, the new lotus root varieties developed by sexual hybridization in China are Yangou No. 1, Xiangbailian No. 1 and so on. The seed selection of lotus root can be carried out by self-breeding or outsourcing, but its quality must be guaranteed.

2. The method of keeping seed

If you want to get lotus root seeds or lotus seeds with high yield and good quality, you should pay attention to the seed retention of lotus roots. When keeping seeds, planting lotus roots will generally spend the winter in the lotus root fields. During the winter, there must be a layer of water level in the lotus root field to avoid water shortage, resulting in soil drought and cracking. If the water level cannot be guaranteed, then the lotus root field should be covered with a layer of straw to keep warm. Then dig out the lotus root in the following winter, and it is best to plant it as you dig. When digging lotus roots, it is not appropriate to dig out all of them. For every four or so lotus roots, one seat should be reserved for the next year.

3. Matters needing attention in keeping seed

The planting method of lotus root is similar to that of planting in the field, but the difference is the time of planting and harvesting. After the lotus root is harvested in the field, it is necessary to continue to manage the field, especially the prevention and control of water, diseases and insect pests in the field. As I just said, it is necessary to maintain a certain water level in winter, and the water level should be controlled at about 4 cm. When digging seeds, the method is the same as digging lotus roots in the field, pay attention to efforts to ensure the completion of planting lotus roots. Prevent bud head injury, resulting in the decline of seed lotus root germination ability and even loss of germination ability.

The above is a brief introduction to the selection and retention techniques of lotus root, there are many propagation methods of lotus root. When we keep seeds, we should choose reasonable breeding methods according to the situation of planting, technology and environment, so as to ensure the yield of lotus root and improve planting efficiency.
