Embodiment Construction

[0006] The present invention is further described below.

[0007] Select dwarf, early-maturing winter jujube varieties; from early to mid-December, put the winter jujube trees into the winter warming greenhouse, close the greenhouse to increase the temperature, that is, cover the greenhouse tightly at night, and roll up the grass thatch on the film of the greenhouse during the day , the temperature in the shed is controlled at no lower than 8°C and no higher than 25°C before budding, no lower than 8°C and no higher than 28°C during the leaf spreading period, no lower than 13°C and no higher than 30°C during the flowering period; The humidity in the shed in front of the shed is kept at 75-85%; the new jujube heads are removed immediately after the winter jujube trees germinate; the fruit branches are topped when they grow to 9 leaves to promote early flowering and fruiting;

[0008] Before the shed is turned on to increase the temperature, that is, after the winter jujube trees...

Abstract

The present invention belongs to fruit cultivating method. The method of promoting maturation of Dongzao jujube includes the main measures of selecting stunted and premature Dongzao jujube variety, setting plastic house in winter and spring to increase temperature, topping off after germination of the tree, tip pruning after the branch grows to 9 leaves to promote early flower to bear, and top dressing with phosphate fertilizer and potash fertilizer. The said method can move up the maturation phase by over 30 days to reach high marketing profits.

Description

technical field [0001] The invention provides a method for cultivating fruit trees, in particular a method for cultivating winter jujube trees. Background technique [0002] Dongzao is an excellent fresh jujube variety with delicious taste and high vitamin content. Because the natural fresh-keeping period and storage fresh-keeping period of winter jujube are very short, so with the rapid expansion of the planting scale of winter jujube, the output of winter jujube also increases rapidly. , which will adversely affect the development of winter jujube and winter jujube planting industry. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for promoting the early maturation of winter jujube so as to improve the economic benefit of planting winter jujube. [0004] The present invention is achieved in this way, a method for promoting early maturation of winter jujube,...
