(a) Select breeding.
The breeding of lotus roots includes asexual selection and sexual cross breeding.
1. Asexual selection.
China's lotus root is rich in germplasm resources and provides good conditions for vegetative selection. In recent years, the varieties selected from the clones of the clones include Kexuan No.1, Elian No.1, Zhehu No.1, and Wuzhi No.2. Number, lotus lotus 85-4, lotus lotus 85-5 and so on. The method of asexual selection is to widely launch the people in the lotus root producing area, and timely report it to the relevant scientific research department or agricultural director for high yield, good quality, strong adaptability, strong disease resistance, special early maturity or special late maturity. Department, and conduct asexual reproduction and promotion.
2. Sexual hybridization.
Sexual hybridization is one of the effective methods to cultivate new varieties of lotus root, and has been widely used in the breeding of lotus root. Sexual hybridization can make full use of the excellent traits of the parents, aiming to cultivate new varieties with high yield, good quality, strong disease resistance, special early maturity or special late ripening. In recent years, new varieties cultivated through sexual hybridization include Elian No. 3, Yangjing No. 1, Elian No. 4 and Xiang Bailian No. 1 and so on.
(b) Retention of species.
To obtain high-yield, high-quality lotus root or lotus seeds, it is very important to keep the lotus seeds. When ploughing, the pheasants must go winter in Putian. During the winter, the field should maintain a shallow layer of water, not dry, cracked. If you can't keep the shallow water often, use straw to cover the cold. Before planting the hoe for the second year, dig out the seed hoe, dig it, and plant it. Per mu of farmland, available for 5 ~ 6 acres of land use. For continuous cropping in paddy field, when picking the panicle, the method of harvesting and sowing shall be used to retain the seed, ie, 0.5m wide and 2m wide and not used for the next year. In each subsequent year, rotations will be collected and retained.
The planting of cultivated fields is similar to that of Daejeon. The only planting and harvesting is later. After field harvesting in Daejeon, it is still necessary to strengthen field management, especially water management and pest control. To keep farming in winter can not cut off water, should maintain 3 to 5 cm shallow water, prevent the soil from drying, so that the seedlings are frozen. The pods are generally harvested and planted as they are planted in the field. Careful care must be taken to keep the pods intact and not to damage the buds.
After the pods are harvested, they should also be selected one at a time when they are planted. According to the characteristics of the species, the selected body is upright, hypertrophied, complete, and there are sub-fistulas at the apex, and there are no pests and no injuries.
In addition, it should also be carried out in the field during the growing season to get rid of miscellaneous and inferior, in time kink pedicel, crushed small buds, so that concentrated nutrients.
In order to explore the breeding techniques of lotus root varieties, the Wuhan Vegetable Research Institute has compared breeding methods of lotus seed propagation, larval rearing, main quail breeding, daughter quail breeding, tardigon propagation, and terminal bud propagation. Observing and analyzing the aspects of yield, quality, growth and development, etc., it is believed that the breeding techniques for the seed pods should be promoted, and the traditional main grazing methods should be improved. It is a simple and easy breeding method. The use of apical buds is a promising breeding method, but it must be matched with the nursery technique. Seed propagation should not be promoted in production, but it is a necessary means in breeding.
