Post-planting cultivation method for winter jujube trees

Abstract

The invention discloses a post-planting cultivation method for winter jujube trees. The method specifically comprises the following steps: ridging is performed after winter jujube saplings are planted, the soil surface of a sapling belt is 15-30 cm higher than the ground, a mulch is laid on each of two sides of the ridge of the sapling belt after a herbicide is sprayed, the jujube trees are clamped between the two mulches, the planted saplings are bagged after herbicide spraying and tied at upper and lower parts, an upper tying opening is 5-8 cm away from the top end of each sapling, a lower tying opening is formed in a rootstock of the sapling, then bud picking, ventilating and untying are performed, the bags are removed when buds grow to 18-22 cm in the bags, topdressing and pest control are performed, and girdling is performed in early full blooming stage of the winter jujube trees. The survival rate of the planted winter jujube trees is increased to 99% or higher through integrated detailed treatment in steps of ridging, mulching, bagging, bud picking, ventilating, untying, bag removal, topdressing and pest control.

Description

technical field [0001] The invention relates to a plant cultivation method, in particular to a cultivation method of winter jujube after planting. Background technique [0002] Dongzao is a high-quality late-maturing fresh jujube variety. The fruit resembles a small apple. The skin is thin and the flesh is crispy. The taste is sweet and slightly sour. It is known as the "king of fruit"; Dongzao is also rich in cyclic adenosine monophosphate, which has high health value, so it is loved by people. Since the end of the 1990s, winter jujube has become a development boom in my country. However, farmers in newly developed winter jujube production areas in my country have very little knowledge of winter jujube cultivation technology, and the cultivation technology is seriously lacking, resulting in a low survival rate of winter jujube seedlings in cultivation. The plant growth is not strong, resulting in serious problems such as low yield, poor quality, and even no fruit in product...

AI Technical Summary

Problems solved by technology

[0003] At present, the new winter jujube orchards have serious dead plants and low survival rate. The main reasons are that the watering is too frequent or too much, the cultivation is not timely, the hardening is serious, or the soil is buried too deep when planting, the root system is not ventilated, and the root system is suffocated; or After planting, the plastic film is not covered, the surface soil is loose, the water retention is too poor, and the root system dies due to drought and water shortage; or the fertilization in the planting ditch is too concentrated and the roots are burnt to death; or the temperature, air humidity, light conditions and soil conditions Can not meet the needs of the tree body

Although there are also some targeted cultivation methods to improve the survival rate of jujube trees, most of them only take a little bit, which is not comprehensive enough, and there is no comprehensive control on the details. As a result, the survival rate of winter jujube trees is still not high. low growth
