Greenhouse grape delayed cultivation method

Abstract

A greenhouse grape delayed cultivation method comprises the following process steps that firstly, fertilization is conducted to supplement nutrients of a tree body, wherein on the basis of thin planting, multi-layer soil-doped fertilization is conducted to supplement nutrients; secondly, pruning is conducted in autumn, wherein a middle-tip pruning mode is used, 4-6 winter buds are reserved on eachfruiting branch, a pruning wound needs to be formed in the position 2-3 cm above each bud eye, and sterilization is conducted after pruning; thirdly, germination is promoted, wherein cyanamide is diluted with water by 25 folds, a cotton ball or a writing brush dips the solution, the winter buds are smeared with the solution, and peripheral scales of the winter buds are completely wetted; fourthly, phonological stages, such as the germination stage, the branch extending stage, the flowering stage, the fruit expansion stage, the color changing stage and the mature stage, are managed, temperature and humidity are strictly controlled in the stages, and topdressing, pesticide spraying and the like are conducted in time. The method is implemented under room-temperature conditions and is not limited by regions; the variety is rich, more options are provided for consumers, and delaying is conducted after primary picking so that fruits can be picked twice in a greenhouse in a year; the methodtakes effect quickly, and the economic value is high.

Description

technical field [0001] The invention belongs to the field of grape cultivation, and in particular relates to a delayed cultivation method of grapes in a greenhouse. Background technique [0002] The traditional open field cultivation of grapes cannot meet the requirements of today's market due to its disadvantages. On the one hand, the quality and yield of grapes cultivated in the open field are unstable. Under open field cultivation conditions, if grapes are subjected to adverse weather conditions such as low temperature, rainfall, and strong winds during flowering and pollination, it is very easy to cause problems such as poor fruit setting and irregular ear shape, so it is difficult to guarantee quality and yield, especially in southern my country. During the development and ripening period of grape fruit, high temperature and rain, high air humidity, insufficient light, serious fungal diseases and other problems often cause problems such as poor coloring and poor quality ...

AI Technical Summary

Problems solved by technology

[0005] This method has certain defects: (1) it has strong geographical restrictions, and this technology can be adopted in the northwest of my country, but it does not meet the conditions in the central and southern regions of my country; (2) it is labor-intensive and the operation is cumbersome To control the late germination of grape winter buds, when the temperature in the solar greenhouse during the germination period is higher than 7°C, the thermal insulation quilt should be pulled up at night, the vents should be opened to lower the temperature of the solar greenhouse, and the thermal insulation quilt should be put down during the day, and the vents should be closed to keep warm. This treatment needs to be repeated for 30-40 days. (3) The varieties have strong limitations. Due to the need for delayed or extremely delayed varieties, such as Red Earth, Autumn Black, Italy, Beauty Finger, and Cresen Seedless, it is extremely difficult to Early-maturing, early-maturing or mid-maturing varieties cannot be used, resulting in a relatively single variety on the market. (4) Germinate in early May, mature in November-December, harvest once a year, and the effect is slow and the utilization rate is low.
