Embodiment 1

[0042] (1) Raising shoots: After harvesting, spray an insecticidal and bactericidal drug once, and use beta-cypermethrin + carbendazim or lime sulfur mixture to clear the garden once, and then prune, thin out the upright branches in the middle, and return to the tree according to the sealing condition of the tree. Shrinkage, if the line is closed, it can be retracted to the biennial branch, if the line is not closed, it can not be retracted. Before pruning, reapply the top-raising fertilizer once. Each Feizixiao lychee fruit tree is applied with 60 catties of sheep manure organic fertilizer + 2 catties of urea + 1 kg of 3 15 compound fertilizers + 1 catties of calcium magnesium phosphate fertilizer. Insect medicine.

[0043] (2) Controlling shoots and killing shoots to promote flowering: use 30 grams of paclobutrazol (30 catties of water to prepare, the following drug dosages are all controlled by concentration, and spray according to conventional methods) before the second bat...

Embodiment 2

[0060] (1) Raising shoots: After harvesting, spray an insecticidal and bactericidal drug once, and use beta-cypermethrin + carbendazim or lime sulfur mixture to clear the garden once, and then prune, thin out the upright branches in the middle, and return to the tree according to the sealing condition of the tree. Shrinkage, if the line is closed, it can be retracted to the biennial branch, if the line is not closed, it can not be retracted. Before pruning, reapply the top-raising fertilizer once, including applying 40 catties of sheep manure organic fertilizer + 3 catties of urea + 1 kg of 3 15 compound fertilizers + 1 catties of calcium magnesium phosphate fertilizer for each Feizixiao lychee fruit tree, and spray 2 times for each shoot. insecticide;

[0061] (2) Controlling shoots, killing shoots and promoting flowering: 25 grams of paclobutrazol (prepared with 30 catties of water, generally can be sprayed on 6 to 8 trees) is used to control shoots before the second batch of...

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...
