Method for regulating and controlling flowering stage of southern grapes

Abstract

The invention provides a method for regulating and controlling the flowering stage of southern grapes. After the southern grapes germinate and inflorescence appears, the inflorescence is removed whenthree leaves are unfolded, and main tip pruning is performed regionally on the southern grapes in the same plantation every 10-12 days from middle of April to the end of May; a growth regulator diluent is uniformly sprayed to leaf surfaces in the first 2 weeks of the main tip pruning and is sprayed once every week, 60-80 cm of main tip is retained after two weeks, and all germinated summer shootsexcept summer shoots at the top end are pruned away; mepiquat chloride diluted 300 times is uniformly sprayed on the leaf surfaces once after the main tip is pruned, and in the tenth day to the twelfth days after pruning, the summer shoots at the top end are pruned away when winter buds at the top end are full to promote germination of the winter buds at the top end. With combination of simple production measures such as spraying of the growth regulator diluent, main tip pruning of the grapes and the like, germination of the winter buds is promoted, the purpose of flowering in different stagesis achieved, the effective rate of flowers is high, and the effect is obvious.

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...

Problems solved by technology

However, due to the complex growth environment of grapes in the south, it is quite difficult to use appropriate production measures to control the flowering period of grapes.
