Method of raising bitter gourd seedlings in greenhouse by grafting

Abstract

The invention discloses a method of raising bitter gourd seedlings in a greenhouse by grafting and belongs to the technical field of raising of bitter gourd seedlings by grafting. The method comprisesthe steps of 1, soaking bitter gourd seeds, and accelerating germination; 2, soaking luffa rootstocks, and accelerating germination; 3, seeding; 4, grafting; and 5, providing management for grafted seedlings. The method herein has the advantages that bitter gourd germination rate and germination potential are high, the seeds germinate quickly and neatly, the seedlings are robust, and the bitter gourd has great potential of yield increase; during seeding, broadcasting is performed, so that time and labor are saved, labor efficiency is high, and production cost is reduced; after cut stems of bitter gourd are grafted by cleft grafting, more robust new roots are induced from roots of luffa rootstocks, more robust growth of grafted plants of bitter gourd is promoted, growth potential is higher, and the yield of bitter gourd is higher; heat insulation, moisture preservation and disease and pest damage control are effectively provided in the management of grafted seedlings, so that survivalrate of grafted seedlings of bitter gourd can be increased.

Description

technical field [0001] The invention relates to a method for grafting and raising seedlings of bitter gourd in a greenhouse, and belongs to the technical field of grafting and raising seedlings of bitter gourd. Background technique [0002] Bitter gourd (scientific name: Momordica charantia L) is a plant of the genus Momordica charantia of Cucurbitaceae, an annual climbing and delicate herb. Sweet and bitter taste, mainly used as vegetables, can also be candied; mature pulp and arils are also edible. Bitter melon is native to East India and is widely cultivated in tropical to temperate regions of the world. It is widely cultivated in the north and south of China. In recent years, the occurrence of soil-borne diseases has become more and more serious due to the replanting of vegetables all year round in vegetable production bases, and the blight of bitter gourd is more common, which often brings devastating losses to the production of bitter gourd in vegetable bases. The g...

AI Technical Summary

Problems solved by technology

The method for grafting and growing seedlings of bitter gourd in greenhouses in the prior art has the following defects: low labor efficiency, high cost, poor heat preservation and moisturizing effect, poor effect of disease and insect pest control, low survival rate of bitter gourd grafted seedlings, low germination rate, weak root system activity, etc.

[0004] One is that the matrix needs to be sterilized, and pesticide costs need to be invested, which increases the production cost

[0005] The second is that bitter gourd and rootstock need to be sown on demand, which is time-consuming and laborious

[0006] The third is to soak bitter gourd at a seed soaking temperature of 50-55°C for 12-24 hours, but because the seed coat of bitter gourd is thicker, the soaking time is short, resulting in low germination rate and low germination potential
