Embodiment 1

[0012] 1. Overview of the test area

[0013] Changsha, Hunan has a subtropical monsoon 3 climate with mild climate, abundant precipitation, rain and heat in the same period, and four distinct seasons. The annual average temperature in Changsha urban area is 17.2°C, the annual accumulated temperature is 5457°C, and the annual average precipitation in the urban area is 1361.6 mm. Changsha has long summers and winters, short springs and autumns, large temperature changes in spring, a lot of rain in early summer, long-lasting high temperatures in autumn, and severe cold in winter. few.

[0014] 2. Test material

[0015] The experiment was carried out at Ganshan Grape Base of Hunan Agricultural University. The grapes are planted in a north-south direction, in the form of flying birds, sheltered from rain, and the spacing between plants and rows is 1.8m×2.8m. Soil, fertilizer, water and pest management are the same as conventional cultivation management. The tested grape varieti...

Abstract

A method for regulating the flowering period of southern grapes, which is to remove the inflorescences when the three leaves are unfolded after the southern grapes germinate and see the inflorescences, and then from mid-April to the end of May, every 10-12 days for the southern grapes in the same plantation. Prune the main shoots in different areas; in the first 2 weeks of pruning the main shoots, spray the growth regulator dilution evenly on the leaf surface, spray once a week, and leave the main shoots 60-80cm after 2 weeks, except for the top summer shoots , and the rest of the germinated summer shoots are all cut off; after pruning the main shoots, evenly spray a 300-fold dilution of mepipeperon on the leaf surface, and on the 10-12th day after pruning, when the top winter buds are full, cut off the top summer shoots to promote the top. Winter buds germinate. The invention combines simple production measures such as spraying the diluent of the growth regulator and pruning the main tip of grapes to promote the germination of winter buds and achieve the purpose of flowering in different periods, with high flowering rate and obvious effect.

Description

technical field [0001] The invention relates to a technical method for regulating the flowering period of grapes in the southern region, in particular to a method for regulating the flowering period of grapes in the south by using a growth regulator diluent combined with pruning measures. Background technique [0002] Grapes are deeply loved by consumers because of their delicious taste, rich nutrition and high functional value. In recent years, due to the extremely abnormal weather in most of the grape producing areas in my country, as the climate changes in various places, the outbreak of extreme weather such as freezing damage in the flowering period and hail in the young fruit period has made the grape flower bud differentiation unstable and the flowering and fruit setting rate low, resulting in insufficient market supply and demand. Coordination, resulting in fruit farmers increasing production but not increasing income and so on. [0003] The control of grape flowering...
