Seedling-growing method capable of improving germination rate of grape seeds

Abstract

The invention mainly relates to the technical field of growing of grapes, and discloses a seedling-growing method capable of improving a germination rate of grape seeds. The seedling-growing method capable of improving the germination rate of the grape seeds comprises the steps of enzymolysis, dormancy, germination acceleration, seeding and management. The provided seedling-growing method capableof improving the germination rate of the grape seeds is simple and convenient to operate, the seeds can be treated in batches, stratification treatment conducted by means of wet sand is avoided, the sleep time of the grape seeds is obviously shortened, space and time are saved, the seedling-growing cost of the grape seeds is reduced, meanwhile, the germination time of the seeds after seeding is conducted is shortened to 4-5 d, the germination rate reaches 68%, and the seedling-growing efficiency of the grape seeds is obviously improved.

Description

technical field [0001] The invention mainly relates to the technical field of grape planting, in particular to a seedling raising method for improving the germination rate of grape seeds. Background technique [0002] Grape is one of the fruits that people like. It is rich in glucose, flavonoids, mineral elements and vitamins. It can beautify and nourish the skin, resist aging, soften blood vessels, and prevent cardiovascular and cerebrovascular diseases. Grapes are delicious and loved by people, so Grapes are widely planted in China. Grapes are mainly asexually propagated in the process of raising seedlings. The main propagation methods are cutting propagation, layering propagation and grafting propagation. The growth cycle is short, and it can bloom and bear fruit quickly, so asexual reproduction is the main propagation method in the grape planting process; however, if the flavor and taste of the grapes change and cannot meet people's taste needs, and the yield is low, It...

[0002] Grape is one of the fruits that people like. It is rich in glucose, flavonoids, mineral elements and vitamins. It can beautify and nourish the skin, resist aging, soften blood vessels, and prevent cardiovascular and cerebrovascular diseases. Grapes are delicious and loved by people, so Grapes are widely planted in China. Grapes are mainly asexually propagated in the process of raising seedlings. The main propagation methods are cutting propagation, layering propagation and grafting propagation. The growth cycle is short, and it can bloom and bear fruit quickly, so asexual reproduction is the main propagation method in the grape planting process; however, if the flavor and taste of the grapes change and cannot meet people's taste needs, and the yield is low, It is necessary to sow and raise seedlings of grapes, and then screen the obtained seedlings to obtain grape plants with better traits; but the traditional method of using grape seeds for seedling cultivation is to place the collected grape seeds in a cool and ventilated place For storage, the seeds are stratified with wet sand 2 months before sowing, and the temperature of the wet sand is kept at about 5°C, and the water content is 10-20%. Then sow in March-April in spring. It takes 15-20 days to germinate, and the germination rate is only about 35%, which obviously reduces the seedling efficiency of grape seeds and makes it more difficult to screen grape plants with good traits. Therefore, the germination rate of grape seeds after sowing should be increased

[0003] The existing patent document CN107371458A discloses a method of sand storage to improve the germination rate of grape seeds, specifically discloses that grape seeds are soaked in chitosan solution and then stored in sand, and discloses that during the process of sand storage, they are first placed in a river sand layer Static storage for 90-100 days, and then placed in the rice bran layer for 2-4 days can increase the germination rate of grape seeds, but the effect is not significant, and the treatment method of grape seeds should be further improved
