A kind of walnut container large seedling breeding method

Abstract

The invention discloses a walnut big container-growing seedling breeding method. The method is high in planting survival rate; during cultivation, the root system of the nursery stock always grows in a container; during the seedling lifting and planting process, the root system and the root system roll are not destroyed, the seedling continuously grows, there is no rejuvenation period, the seedling can be planted in four seasons, and the survival rate reaches 100%. Early-stage nutrition growth is completed in the container, fruiting is started, and the seedling directly enters into the initial fruit period after the seedlings are planted. Labor-saving cultivation is facilitated, the young tree shaping has been completed, the tree shape framework is unified, the young tree period management is saved, tree body pruning in the fruiting period is simplified, and meanwhile the mechanical management is facilitated; big container-growing seedlings are uniform in specification, the orchard uniformity is high and standardization management is facilitated. Firstly, fruits are seen and then the trees are planted, the quality of the variety can be identified in advance, the inferior variety is removed, the problem of fine-variety mixing is solved, and the realization of the 'one-orchard one-product' is facilitated, the commodity rate and the economic benefit are improved, transportation and cultivation are facilitated, and the method has the popularization and application values.

Description

technical field [0001] The invention relates to a nursery stock cultivation method, in particular to a walnut container large seedling breeding method. Background technique [0002] In recent years, due to the high price of grafted walnut seedlings of improved varieties, the demand is large, the supply exceeds demand, and the breeding technology is poor, it is easy to mix improved varieties, the survival rate of planting is low, the slow seedling period is long, the planting work is cumbersome, it is not conducive to management, and transportation is difficult , Therefore, a new breeding technique needs to be born. Contents of the invention [0003] The object of the present invention is just to provide a kind of walnut container large seedling propagation method in order to solve the above problems. [0004] The present invention achieves the above object through the following technical solutions: [0005] The present invention comprises the following steps: [0006] (...
