Grape cultivation method

Abstract

The invention belongs to the field of grape planting, and particularly relates to a grape cultivation method. The specific technical scheme comprises the following steps of forming a planting ditch, and transplanting a grape seedling into the planting ditch; before germination, applying diammonium phosphate; after germination and shooting, selecting a robust new shoot, culturing the new shoot intoa main vine, and culturing 3-5 main vines for each nursery stock; when a main vine shoot grows to be 50-60 cm, carrying out pinching, reserving 2-4 secondary shoots on the main vine, leaving 7-8 leaves for each secondary shoot, and carrying out pinching; spraying a nutrient solution to the leaves before flowering; spraying a gibberellin aqueous solution once in each of the initial flowering period and the full flowering period; after fruit setting, applying nitrogen fertilizer, and controlling the fruit cluster amount after fruit setting and spraying nursing liquid; in the fruit swelling period, applying potash fertilizer and ternary compound fertilizer; and spraying potassium dihydrogen phosphate to the leaf surfaces before fruit maturation. Grapes are planted by the method, so that thefruit setting rate of the grapes can be effectively improved, fruits are expanded, the fruit quality is improved, the yield of the grapes per mu is high, the fruit cracking rate is extremely low, andthe comprehensive economic benefit is excellent.

Description

technical field [0001] The invention belongs to the field of grape cultivation, and in particular relates to a grape cultivation method. Background technique [0002] In recent years, the table grape industry has developed rapidly, and the planting area has continued to increase. However, there are still big problems in the production of table grapes in China. Due to unreasonable cultivation methods, the yield of grapes is generally low, the quality varies, and the fruits are prone to cracking, which cannot meet the needs of the high-end market. [0003] Usually, the fruit cracking rate of grapes is about 5%, and in severe cases, it is 15-20%. In years with more rain, the fruit cracking rate is even as high as 70%, which seriously affects the grape harvest. The main reason for grape cracking is that the growth rate of the peel is not as fast as that of the pulp, and the excessive growth of the pulp bursts the peel and causes cracking. Therefore, adjusting the growth rate o...
