Embodiment Construction

[0009] 1. Cultivation of the mother tree

[0010] The cultivation of the mother tree is the same as the normal planting method of soaked walnuts, and it is planted according to the "seven ones" standard, that is,

[0011] Choose a good land: choose a plot with an altitude of 1400 meters to 2000 meters, a soil with a rock content above medium, loose, fertile, and sufficient sunlight for afforestation.

[0012] Dig a large pond and apply a load of farmyard manure: dig a large pond with a length, width, and depth of more than 80 cm, apply a load of farmyard manure, and put it back into the cultivated soil to ensure sufficient nutrition in the young tree stage.

[0013] Choose a good seedling: choose a walnut variety suitable for afforestation plots, grow vigorously, have no pests and diseases, and have good genetic quality seedlings for planting.

[0014] Pour a load of water, cover a piece of film, and cover a bamboo cage: During planting, pour a load of root water to ensure th...

Abstract

A bridge graft technique for promoting the root growth of young walnut tree includes such steps as burying 3 walnut fruits along a circumference of a circle with 20-50 cm for diameter and a circle center where a mother tree is planted, growing 3 saplings until their height is 40 cm or more, and bridge grafting between saplings and mother tree.

Description

technical field [0001] The invention relates to a woody plant cultivation technology, in particular to a technology for bridging young walnut trees to increase root growth. Background technique [0002] Walnut cultivation has a long history and is widely cultivated due to its good economic, ecological and social benefits. However, it takes 5-7 years for walnuts to bear fruit after planting, and the high-yield period is longer. Under normal conditions, it takes 10-15 years to enter the high-yield period after planting. The long sapling period seriously restricts the production efficiency of walnuts. play. [0003] In response to this situation, the predecessors mainly promoted the growth of walnut saplings by adding fertilizers, improving soil water and fertilizer conditions, and increasing the supply of soil nutrients, but the investment was large. Contents of the invention [0004] Aiming at the deficiencies in the above-mentioned prior art, the present invention propos...
