Hickory big seedling culture method

Abstract

The invention provides a hickory big seedling culture method, comprising selecting nursery land, preparing land, preparing seedlings, digging holes, and applying fertilizer, planting, performing seedling management after fixing, performing big seedling water and fertilizer management, shaping and pruning big seedlings, performing tillage and weeding on the big seedlings, and controlling pests on big seedlings. Through the method, prominent problems that survival rate of plantation and preserving rate of farmland forest nets, country roads, production roads, canals, villages, and river dams are relatively low. An improved variety of grafting big seedlings with fruits as primary is provided. Except survival rate and preserving rate are improved, big seedlings are used to afforest, one-time afforestation and one-time forest establishment can be realized according to planning requirements, primary density is not needed, seedling use amount is reduced, intermediate cuttings is not needed, forest form is in order, early harvest can be realized. Big seedlings bear fruits in the third year, and enter a high-yield period in the fifth to seventh year. 8-12 plants are planted in each mu, and the method is beneficial for realizing mechanization.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a method for growing large hickory seedlings. Background technique [0002] Long pecan is mainly produced in the United States. It was introduced from the United States at the end of the 19th century and the beginning of the 20th century. It has been cultivated in many provinces in the north and south of my country, but the output is low and unstable, and no industry has formed. After decades of development in the United States, especially through the selection and breeding of fine varieties after successful grafting in the 1960s, it has developed rapidly. The current output is more than 300,000 tons. In recent years, long pecan products have appeared in the domestic market. Among these tree species, pecan has the most unique fragrance, high unsaturated fatty acid, high Ca, high K content, and is famous for its health care function. It is a unique economic forest dried fruit i...

Problems solved by technology

[0005] Under the current situation of multi-purpose and rapid development, the main problems in the production of long hickory seedlings are: (1) afforestation of annual bare-root seedlings in mountain farms, high tending costs, low survival rate, and low preservation rate; (2) two Annual grafted seedlings, bare-rooted seedlings have a long slow seedling period after afforestation, and basically do not grow in the first year, with weak branches and weak trunks, which will have a greater impact on future high yield and success; 1-2 years old seedlings can be used for afforestation in river dams, roads, and villages Man-made, livestock, machinery and other hazards are serious; after afforestation of young seedlings, the care and management cannot keep up, resulting in serious diseases, insects and grass shortages
