Method for shortening fruit mature period of Feizixiao litchi

Abstract

The invention discloses a method for shortening the fruit mature period of Feizixiao litchis. The method comprises the following steps: (1) culturing tips; (2) controlling and killing tips to promote flowering; (3) blending; (4) flower thinning; (5) fruit retention; and (6) fruit strengthening. The Feizixiao litchis obtained through the method are high in female flower proportion, high in fruit setting rate, short in fruit maturation period, early in marketing and high in economic value.

Description

technical field [0001] The invention belongs to the technical field of lychees, and in particular relates to a method for shortening the ripening period of Feizixiao lychee fruits. Background technique [0002] Existing lychee cultivation method one: [0003] Harvest, pick the ear and 2-3 leaves at the lower section of the ear at the same time; promote autumn shoots, including topdressing nitrogen, phosphorus and potassium fertilizers; use 20% polyethylene glycol for root irrigation; control winter shoots, ring cutting, and combine with ring cutting Spray 95% ethanol and 2%-4% lime water on the leaves; promote flower bud, spray compound cytokinin 1-2 times during flower bud germination stage; Mixed solution for bud thinning; during flowering period, spray calcium phosphate, glycine and sucrose fatty acid mixture for flower thinning; for fruit stabilization, spray potassium dihydrogen phosphate, 6-benzylaminopurine, naphthalene acetic acid, ethylene glycol, sucrose during fr...

Problems solved by technology

[0010] The above two methods all have the disadvantages of late control of shoots, resulting in late flowering, low proportion of female flowers, late fruit maturity, late listing, and low price.

In addition, the first method has the disadvantages of using too many drugs and high cost, and the second method has disadvantages such as poor operability.
