Seedling culture method of all-female balsam pear

Abstract

The invention provides a seedling culture method of an all-female balsam pear. According to the invention, the seedlings are obtained from grafting the scions of all-female plants, because of the stock, compared with all-female balsam pear seed seedlings, the root system of the grafted seedling plant is much more developed, the growth vigor is strong, the resistance is strong, the disease and insect pests are less, the yield of the balsam pears is large, and the yield of the hybrid seed production is large. Furthermore, the germination force of all female buds of the balsam pear is strong, andone lateral branch is extracted from each bud, the buds of the lateral branches can also grow to lateral branches, and one all-female plant can be used for producing unlimited lateral branches to beused as scions for grafting 'infinite' seedlings to form 'infinite' all-female plants. The seed yield of loofahs is larger than that of balsam pears, normally, the seed yield of loofahs is 300-500 grains per loofah, the seed yield of balsam pears is 20-30 grains per balsam, and the seeding culture of loofahs is easier than that of balsam pears, and the stock can be easily obtained. According to the invention, a large amount of all-female balsam pears can be simply and effectively obtained, the pollution caused by silver nitrate to the environment is avoided, and the yield of the seeds is high.

Description

technical field [0001] The invention relates to the technical field of vegetable seedling cultivation, in particular to a method for raising seedlings of whole female bitter gourd. Background technique [0002] Bitter gourd is rich in multivitamins, especially vitamin C, which ranks first in melons, and also contains a variety of minerals needed by the human body. Bitter gourd fruit has good edible value; etc., as well as the effects of lowering blood sugar, lowering blood fat, antibacterial and anticancer, etc., and has good medicinal value. The planting area and sales volume of bitter gourd have increased rapidly in recent years. Bitter gourd has a strong hybrid advantage. At present, hybrid varieties are mainly used in the production of bitter gourd, and the demand for hybrid bitter gourd seeds is large. Using the whole female bitter gourd as the female parent for hybrid seed production is the most convenient and labor-saving method for hybrid seed production of bitter ...

Problems solved by technology

To use such a strong female line as the female parent for seed production, it is necessary to manually pull out the male plants or cut off the male flowers with male plants, which will waste plants and cost labor

Another method is to use silver nitrate solution to induce the female flowers of the whole female plant to produce hermaphroditic flowers, and take the male pollen of the hermaphroditic flowers to pollinate the female flowers of the whole female plant. The obtained seeds are theoretically divided into whole female plants, but in fact there are still a few plants For male plants, this method of inducing hermaphrodite flowers with silver nitrate solution not only pollutes the environment with toxic silver nitrate, but also the seed yield is not high
