A kind of cultivation method of delaying grape ripening period

Abstract

The invention belongs to the technical field of agriculture, and particularly relates to a cultivation method capable of delaying a grape mature period. By increasing the winter soil thickness and spraying an enzyme inhibitor and a growth inhibitor, the grape mature period is delayed, the winter soil thickness is increased, the soil unfreezing time is delayed, and therefore grape growth is delayed; the enzyme inhibitor can slow down protein, starch and saccharose decompositions so that not enough energy can be provided for bud germination, and bud germination is delayed; the growth inhibitor can inhibit cell fission and differentiation, the gibberellin induction effect can be inhibited, shoot growth is delayed, and meanwhile the grape disease resistance can be enhanced. According to the cultivation method capable of delaying the grape mature period, the grape mature period can be delayed to the middle ten days of November, and the obtained grape quality is good.

Description

technical field [0001] The invention belongs to the technical field of agriculture, in particular to a cultivation method for delaying the ripening period of grapes. Background technique [0002] Grape belongs to a kind of berry, its shape is mostly round or oval, and its color varies with the variety. It has the characteristics of rich nutrition, bright color, delicious taste and wide application. Grapes have strong growth ability and can grow in various soils. They are widely planted in the world, and their output accounts for almost a quarter of the world's fruit output. Grapes can be used as fresh fruit, and can also be processed into wine, raisins and beverages. More than 80% of the grapes produced in my country are used for fresh consumption. The production of fresh grapes is the main body of my country's grape industry. [0003] The grape varieties in my country are mainly mid-ripening varieties. The fresh grapes in the southern region generally end their ripening pe...

Problems solved by technology

This year, in order to meet the market demand of grapes in the off-season and to increase the income of fruit farmers, many scholars have conducted related research on delayed cultivation techniques for grapes. At present, there are two main delayed cultivation techniques: one is to promote The growth of the secondary fruit of grapes, the ripening time of the secondary fruit is later than that of the primary fruit, and the purpose of delaying the listing of fresh fruit is achieved by the method of twice a year, but the yield of the secondary fruit is low, the ears are not neat, the ears, The quality of the grapes obtained is low and the value is low; one is to delay the germination and flowering time of the grapes, thereby delaying the maturity of the fruit. This technology mainly achieves the goal by controlling the growth environment of the grapes. The quality of the grapes obtained is better

[0004] Nowadays, in order to improve the quality of grapes, people mostly use the method of delaying grape germination and flowering time to delay grape maturity, but there are problems such as short delay time, low quality, and high management costs.

For example, the cultivation method disclosed in the document with the patent application number 201110248055.0 to delay the ripening period of grape sprouting main shoots, delays the growth of new shoots and the formation of inflorescences by pruning and spraying paclobutrazol growth inhibitors, which has the problem of short delay time. Fertilization was not applied during the budding and flowering stages of the grapes, resulting in the problem of small fruit grains
