A medicament and method for breaking the dormancy of winter buds of grapes and making fruits ripen in advance

Abstract

The invention discloses a medicament for breaking the dormancy of winter buds of grapes and making the fruit ripen in advance. The medicament comprises: sodium tungstate 0.5%-2%w / v, sodium nitroprusside 0.03%-0.09%w / v, potassium sulfate 1 %‑3%w / v, diammonium phosphate 1%‑3%w / v, 5‑azacytidine 0.2%‑0.8%w / v, brassinolide 0.01%‑0.04%w / v. The invention solves the lack of a non-toxic or low-toxic agent in the prior art, which can effectively break the dormancy of winter buds of grapes, promote early germination and early ripening of fruits. The invention also discloses a method for breaking dormancy of winter buds of grapes and ripening fruits in advance. The above-mentioned medicine is evenly applied to winter buds of grapes or evenly sprayed on branches and winter buds of grapes. The phenological phases such as the ripening period and fruit ripening period were all advanced in varying degrees, and there was no adverse effect on the germination rate, branching rate and fruiting branch rate of grape winter buds after treatment.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting and cultivation, in particular to a medicament and a method for breaking the dormancy of winter buds of grapes and making fruits ripen in advance. Background technique [0002] Bud dormancy is a beneficial biological characteristic acquired by higher plants through long-term evolution to adapt to extreme low temperature conditions and seasonal changes. Once a perennial deciduous fruit tree enters internal dormancy, it must satisfy a certain amount of low temperature accumulation to release it; insufficient low temperature accumulation will lead to abnormal germination, flowering, fruit setting, and branch and leaf growth, which will seriously affect the production capacity of the tree. Due to the characteristic of dormancy, the fruit tree cultivation area is limited, and it is also a problem that must be considered in the protected cultivation of fruit trees; in recent decades, global ...

However, cyanamide is a highly toxic substance, which is inconvenient and unsafe to use. If a small amount of cyanamide is splashed on the skin during use, it will cause peeling, and in severe cases, it will cause skin redness, pain, and vomiting. They cannot drink alcohol within 3 days after the treatment, and some people with severe cyanamide allergies will experience skin itching, dizziness, nausea and other symptoms when they go to the vineyard within a week after taking the medicine, which seriously affects the normal production and life of the fruit growers.
