Embodiment 1

[0029] 1) Using Fuji and Golden Delicious apples as materials, referring to the facility structure described by Li Shijun (Facilitated Horticulture [M]. Beijing: China Agricultural Press. 2002), according to the growth and development characteristics of apples, we design apples for rain-proof cultivation. Steel frame greenhouse, single shed length 50m, shed width 6m, shed height 3.8m ( figure 1 ), throughout the growing season, except that the spraying of pesticides is different from that of open field cultivation, the pruning methods and the use of fertilizers are the same as those of open field cultivation.

Abstract

The invention belongs to the field of agricultural cultivation and discloses a method for rain shelter cultivation of apples. The method comprises the following steps of: building a multi-span steel frame plastic greenhouse of which a single greenhouse has a length of 50m, a width of 6m and a height of 3.8m by taking Fuji or Golden delicious apples as a material, covering a plastic film with the thickness of between 0.06 and 0.12mm on the Fuji apples during germination, covering a plastic film with the thickness of between 0.06 and 0.12mm on the Golden delicious apples after a late flowering stage, and removing the covered plastic films in early October, wherein a pruning method and the use of fertilizers are the same as those of culture in the open expect for pesticide spraying in the whole growing season. By the method for the rain shelter cultivation of the apples, diseases such as ring rot, anthracnose, rot and alternaria leaf spot of the apples are effectively reduced, the finishof the surfaces of the apples is improved, and the coloring effect of fruits is improved. In the whole growing season, the spraying times of pesticides are remarkably reduced, so that the pesticide cost and labor cost are reduced; and the method has a remarkable effect of preventing the diseases.

Description

technical field [0001] The invention belongs to the field of agricultural planting and relates to a rain-proof cultivation method for apples. Background technique [0002] 1 The principle of rain shelter cultivation technology [0003] Rain-shelter cultivation is a method of covering the top of the crown with plastic film for the purpose of sheltering from rain. It is the simplest and most practical method in facility cultivation. For rain-borne diseases such as anthracnose and spot defoliation, the trees are not in direct contact with rainwater due to the covering of the film, which cuts off the path of pathogen transmission and reduces the possibility of disease occurrence (Li Jinchao, Duan Luoshun, Zhang Xiaoshen. Rain shelter has a great impact on grape diseases and Effect of light intensity. Acta Fruit Tree, 2009, 26(6): 847-850). Therefore, during the rain-shelter cultivation process, the occurrence of diseases is reduced while reducing the use of pesticides. [000...
