Five-step apple stock continuous layering propagation method

Abstract

The invention discloses a five-step apple stock continuous layering propagation method. The five-step apple stock continuous layering propagation method includes the steps of carrying out piece-root grafting on stock root sections and self-rooted stock variety scions; then carrying out ditching deep planting on the piece-root-grafted seedlings; carrying out pinching branch promotion on the grafted seedlings, restraining the heights of the seedlings, and promoting sprouting of auxiliary buds on the lower portions of the seedlings to increase the propagation seedling number; taking roots multiple times in batches through cultivating media comprising, by weight, 1 part of garden soil and 1 part of river sand, and finally pushing ridged soil aside to carry out shearing to obtain stock seedlings; properly carrying out ridging every year from the second year, growing out young sprouts, and repeating the working process of the last year to obtain stock seedlings. Compared with the prior art, the propagation efficiency is greatly improved, and the five-step apple stock continuous layering propagation method has the advantages of being high in propagation efficiency and saving time and labor.

Description

(1) Technical field [0001] The invention relates to a five-step propagation method for horizontal layering of apple rootstocks, which belongs to the field of fruit tree cultivation, and in particular to a five-step efficient horizontal layering method for rooting, deep planting, topping, layering, and cultivation substrate. (2) Background technology [0002] High-quality apple seedlings are the foundation of the apple industry. Due to the long-term use of seed stock in my country, the uniformity of the seedlings is poor, the uniformity of the orchard is poor, and the commerciality of the fruit is poor. Using self-rooted seedlings is an important way to solve this bottleneck problem. Self-rooted seedlings are directly rooted and cultivated from rootstocks through vegetative propagation, which can not only overcome the defects of young physiological age and late fruit bearing of seed grafted seedlings, but also have the characteristics of consistent tree development, early fr...

AI Technical Summary

Problems solved by technology

[0004] At present, the horizontal layering method used in production is to directly cultivate the soil, which has a large workload and high labor intensity, and the seedling output is far inferior to that of seedling breeding, which increases the breeding cost of self-rooted seedlings; at the same time, due to the randomness of materials and tools, the operation It is difficult to standardize, and the quality of the propagated seedlings is not high, which is not conducive to the propagation of large-scale self-rooted stock seedlings
