Abstract

A Close planting and high production cultivation method of early bearing walnuts includes the following steps of nursery area selection: selecting an area which is flat in terrain, fertile in soil and loosened in soil property to be a nursery area; selection of seedlings to be planted: selecting seedlings as the seedlings to be planted, wherein graft union shoots of the seedlings reach above 80cm, root systems of the seedlings are complete, the lengths of main roots of the seedlings are above 20cm, and the seedlings have more then 10 strips of branch roots; management after planting: cutting back, pinching, bud picking, side shoot removing, pruning, and auxiliary branch pruning; and fertilization management and insect control: using a sprayer which can spray chemical pesticide to directly spray mist or eradicate insects partially.

Description

Technical field [0001] The invention relates to a high-yield cultivation method of early-fruiting walnut dense planting. Background technique [0002] Walnut ranks first among the world's four major dried fruits for its rich nutrition and unique flavor, and is deeply loved by people. Walnut tree planting is divided into two types according to time: spring planting and autumn planting: spring planting is planting after the soil is thawed and before the seedlings germinate; autumn planting is planting the autumn seedlings after the leaves are fallen and before the soil is frozen. Walnut trees planted in autumn have the characteristics of early sprouting, fast growth and robustness in the following spring, but walnut trees planted in autumn have the disadvantages of severe frostbite in winter and low survival rate. Summary of the invention [0003] One of the objectives of the present invention is achieved through the following technical solutions: [0004] Nursery selection: Choose ...
