Secondary-bearing viticulture method

Abstract

The invention discloses a secondary-bearing viticulture method, including the steps of (1), pruning grapevines in early-mid January in winter; (2), spraying a dormancy breaking agent A when the internal mean daily temperature of a greenhouse reaches 5-10 DEG C; (3), waiting for germinating in the middle ten days of February and blooming in the middle ten days of April; (4), lifting four sides of the greenhouse film and changing into the mode of under-shelter cultivation in the early ten days of May; (5), selecting cluster when first crop of fruit enters the swelling period; (6), secondary pruning; (7), applying organic fertilizer and compound fertilizer for one time before germination of second crop of fruit; (8), waiting for germination of winter bud of second crop of fruit in the last ten days of August; (9), selecting cluster when second crop of fruit enters the swelling period, and performing top application of compound fertilizer for one time. According to the secondary-bearing viticulture method, cultivation of grapevines is improved based on facility, germination, blooming and bearing of grapevines are earlier than usual, secondary germination is achieved after the first crop of fruit is harvest and on the market, so that the cultivation mode of yielding two crops a year is achieved by combining early-maturing promoting and culture delaying according to the post thermal-insulation and culture delaying technology.

Description

technical field [0001] The invention relates to a grape cultivation technique, in particular to a cultivation method for secondary fruiting of grapes. Background technique [0002] At present, China's grape industry is in a critical period of moving from traditional agriculture and industrial agriculture to modern agriculture. Some new production methods and development methods are rapidly integrating into the grape industry. China has become the country with the largest area of ​​protected grape cultivation in the world. The important reason is that the fruit quality after protected cultivation is good, there are many varieties, the market price is high, and the profit is good. It has become a hot spot for agricultural structure adjustment in various places. The output value per mu of grapes cultivated with rain shelter technology in various parts of the south is more than 10,000 yuan, and the highest output value is 50,000 to 60,000 yuan per mu. However, under the condit...

Problems solved by technology

In terms of grape secondary fruiting technology, from simple pruning measures to various physical methods, chemical agents and other measures to inhibit growth, promote flower bud differentiation, break dormancy, etc., but there are few systematic and comprehensive studies on grape secondary fruiting.
