Rapid shaping method applicable to jujube trees after branch removing in Tai-hang mountain gneiss area

Abstract

The invention relates to the technical field of jujube tree cultivation, and specifically discloses a rapid shaping method applicable to jujube trees after branch removing in a Tai-hang mountain gneiss area. The method specifically comprises the steps of reserving a first layer of new shoots and cultivating after branch removing in the first year, grafting by taking the first layer of new shoots as rootstocks in the spring of the next year, reserving a second layer of new shoots for cultivation below at the same time, grafting by taking the second layer of new shoots as rootstocks in the spring of the third year, shaping in the fourth year, and directly shaping the tree body. The rapid shaping method has the advantages of small wound, rapid healing, high survival rate of grafting and low wind breakage death rate; the reserved branches are high in growth, the branches are large in quantity, and the root system is rejuvenated; and the shaping speed is high, and the time for entering a high-yield period is short.

Description

technical field [0001] The invention relates to the technical field of jujube cultivation, in particular to a rapid prototyping method suitable for dried jujube trees in the gneiss area of ​​Taihang Mountains. Background technique [0002] The Taihang Mountain gneiss area is located at 36°58′~37°2 2′ north latitude, 113°50′~115°2 3′ east longitude, 350~700m above sea level, with an annual average temperature of 10~12℃, large temperature difference between day and night, frost-free period 175-190 days, sunshine hours 2534 hours, annual rainfall 580ml, and uneven distribution, 80% concentrated in summer, severe drought and water shortage. The soil layer on the mountain slopes in this area is shallow, generally 15-20 cm. The soil is coarse and barren soil with low organic matter content, poor soil development, poor water and fertilizer retention capacity, insufficient effective mineral elements, and serious desertification. [0003] Jujube is resistant to drought and barrennes...

Problems solved by technology

[0005] Aiming at the problems of large wounds, difficult healing, low grafting survival rate, small amount of branches and leaves, root system wilting and death in the prior art, the branches are easy to break and die, and the forming is slow, and it takes a long time to enter the high-yielding period in the prior art. Provide a rapid forming method suitable for jujube trees in the gneiss area of ​​Taihang Mountains after drying. This method has small wounds, fast healing, high survival rate after grafting, and low wind-break mortality rate; the reserved branches grow fast and have large branches and leaves. Rejuvenate the root system; and the formation is fast, and the time to enter the high-yield period is short
