Cultivating method for improving yield of jujube tree

Abstract

The invention discloses a method for improving yield of a jujube tree. Particularly, ridging is performed after a jujube sapling is planted so that the soil surface of the sapling is higher than an original ground by 15-30 cm. After herbicide is sprayed, a ground film is paved on each of two sides of a sapling ridge. The jujube sapling is fixed at the central part of two ground films. After a pesticide is sprayed on the planted sapling, bagging is performed. The upper opening and the lower opening are tied. The upper tied opening is separated from the top end of the sapling by 5-8 cm. The lower sealed opening is arranged at the root part of the sapling. Debudding, ventilation and untying are performed. On the condition that a bud has grown to a length of 18-22 cm in the bag, debagging, additional fertilizer application and insect controlling are performed. Girdling is performed at the early period in blooming of the jujube tree. Through integrated detail processing on the steps of ridging, film covering, bagging, debudding, ventilation, untying, debagging, additional fertilizer application, insect controlling and girding, the cultivating method has advantages of improving survival rate of planting, increasing yield of the jujube tree in the current year, effectively improving fruit setting, preventing fruit falling, promoting fruit swelling and improving yield of the jujube.

Description

technical field [0001] The invention relates to a plant cultivation method, in particular to a cultivation method for improving the yield of winter jujube trees. 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 f...

Problems solved by technology

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 production.

[0003] In addition, because the winter jujube tree has the characteristics of large flowers, many heads, strong polarity, excessive vegetative growth, and strong light-loving jujubes, etc., which far exceed other jujube varieties, resulting in Zhanhua winter jujube. Fruit setting is difficult, Hard to keep fruit
