Method for promoting lateral rooting of annual carya illinoensis seed seedling

Abstract

The invention belongs to the technical field of fruit trees and forestry cultivation, and discloses a method for promoting the lateral rooting of a annual carya illinoensis seed seedling, the root of a sprouting carya illinoensis seed seedling is mechanically cut, and a pair of scissors is utilized to cut the part below the fibrous root; and the seedling which is subjected to mechanical root cutting is transplanted into a nutrition pot, melon seed-shaped pebbles are laid on the bottom of the nutrition pot for 5 centimeters, and a nylon net is cushioned on the melon seed-shaped pebbles. A matrix is put in a container, the seedling is transplanted in a facility which is cold-proof and sun-proof for one month, a furrow which has the width of 13 centimeters and the depth of 20 centimeters is defined in a seedbed of a land, and the row spacing of the furrow is 30 centimeters. A layer of non-woven fabric is laid at the bottom of the furrow, a chemical rooting-resistant agent is coated on the non-woven fabric, and the nutrition pots which are planted with the seedlings are put on the non-woven fabric according to the planting distance of 20 centimeters, and are fixed finally. The water and fertilizer management period is normally carried out. The method can be used for effectively promoting the lateral rooting of the carya illinoensis seed seedling.

Description

technical field [0001] The invention belongs to the technical field of fruit tree and forest tree cultivation, and in particular relates to a method for promoting the occurrence of lateral roots of pecan seedlings in the same year. The method can effectively promote the occurrence of a large number of lateral roots in the pecan seedlings of the current year. Background technique [0002] Thin-shell hickory is an ecological and economical tree species integrating high-grade thousand fruits, landscaping and high-grade wood. Originally produced in the United States and northern Mexico, it has been introduced to China for 110 years, but has not formed industrialized development. One of the important factors restricting its development is that seedling propagation technology is not up to standard. Thin-shell hickory seedlings are mainly propagated by grafting. The cultivation of rootstock is one of important links in the grafting process, and the rootstock of Carya Carya mostly...

AI Technical Summary

Problems solved by technology

Bare-root seedlings cultivated by traditional field seedling cultivation methods have very few lateral roots ( figure 1 ), the quality of seedlings is poor, the survival rate of transplanting is low, and the slow seedling time is often

To a large extent, it has affected the propagation of hickory seedlings with thin shells, and then affected the development of its industrialization
