Planting method for promoting flower bud differentiation of facility-planted yellow-flesh nectarine trees

Abstract

The invention provides a planting method for promoting flower bud differentiation of facility-planted yellow-flesh nectarine trees. The planting method comprises the steps of pruning management, earlypromoting management, later control management and environment management; the pruning management comprises post-harvest pruning and fruiting period pruning; the early promoting management is carriedout, specifically, (1) water and fertilizer are supplemented; (2) the number of reserved branches is controlled, specifically, the branches are controlled to be 18-22 when flower bud differentiationis completed; (3) pinching treatment is carried out; the later control management is carried out, specifically, (1) drought vigorous growth control is carried out; (2) amino acid vigorous growth control is carried out; (3) ditching and root cutting vigorous growth control is carried out; (4) pruning vigorous growth control is carried out; the environment management is carried out, specifically, (1) in a flower bud differentiation period, mulching films and green house films are uncovered when young sprouts grow to 20-25cm, and the young sprouts are enabled to grow in the open air; and (2) in adormant period, a facility is subjected to cold accumulation dormancy, and the facility is kept for 50-60 days at the temperature of 7 DEG C or below and the humidity of 60% - 70%. According to the planting method for promoting the flower bud differentiation of the facility-planted yellow-flesh nectarine trees, the flower bud differentiation of the yellow-flesh nectarine trees can be promoted, more plump flower buds with higher quality are formed, the ripening time of the yellow-flesh nectarine trees is advanced, and the yield is remarkably increased so that higher economic benefits can be obtained.

Description

technical field [0001] The invention belongs to the technical field of nectarine planting, in particular to a planting method for promoting flower bud differentiation of yellow-fleshed nectarine trees grown in facilities. Background technique [0002] Yellow-fleshed nectarine is an early-maturing nectarine variety with full red color, bright and beautiful appearance, yellow flesh, crisp and sweet taste, and rich nutritional value. It is a high-quality variety with high acceptance in the market. The flower bud differentiation time of the yellow-fleshed nectarine trees planted in facilities using conventional planting techniques is from mid-February to mid-March, and the maturity time of the yellow-flesh nectarines is from late March to late April. The early maturity of yellow-fleshed nectarines can achieve early market and obtain good returns. The flower bud formation and differentiation of yellow-fleshed nectarine trees is a very complicated process. The research on the mec...

Problems solved by technology

The flower bud formation and differentiation of yellow-fleshed nectarine trees is a very complicated process. The research on the mechanism of flower formation has been done for a hundred years, but how to promote the flower bud differentiation of yellow-fleshed nectarine trees in facilities to promote early yellow-flesh oil There is still little research on peach ripening time and improving yield
