Embodiment 1
[0073] (1) On January 3, 2016, the grape branches were pruned in winter; when pruning, 2 buds at the base of the resulting mother branch were left, and the rest were cut off. After half a month of pruning, the shed was closed. When the shed was closed, it was covered with double-layer film, and the ground was covered with straw Covering, the thickness of the straw is 3-5cm, and the temperature rises naturally;
[0074] (2) When the daily average temperature in the shed reaches above 5°C, spray sleep-destroying agent A, and carry out germination treatment to force winter buds to germinate; sleep-destroying agent A contains potassium nitrate of 0.08mol / L, inositol of 0.02mol / L, 0.007 mol / L HClO, 4g / L chitosan, 0.5g / L ethylene glycol, 0.25g / L GA 3 , 0.009mg / L TDZ, 0.02mg / L indole acetic acid, 1g / L mineral oil and 2g / L alkyl polyoxyethyl ether;
[0075] (3) The daytime temperature in the shed is kept at about 17°C, the nighttime temperature is 10-12°C, and the humidity is 70±5%RH...
Embodiment 2
[0083] (1) The grape branches were pruned in winter on January 10, 2017; when pruning, 2 buds at the base of the resulting mother branch were left, and the rest were cut off. After half a month of pruning, the shed was closed. Covered with straw, the thickness of the straw is 3-5cm, and the temperature rises naturally;
[0084] (2) When the daily average temperature in the shed reaches above 5°C, spray sleep-destroying agent A, and carry out germination treatment to force winter buds to germinate; sleep-destroying agent A contains potassium nitrate of 0.09mol / L, inositol of 0.03mol / L, 0.006 mol / L HClO, 4g / L chitosan, 0.4g / L ethylene glycol, 0.2g / L GA 3 , 0.01mg / L TDZ, 0.03mg / L indole acetic acid, 1g / L mineral oil and 2g / L alkyl polyoxyethyl ether;
[0085] (3) The daytime temperature in the shed is kept at about 20°C, the nighttime temperature is 12-15°C, and the humidity is 70±5%RH. Germination begins on February 16, and flowering begins on April 17. There are 4 leaves at th...

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...
