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 ...
