Embodiment Construction

[0015] 1. Determine GA 4 the appropriate concentration of

[0016] Collect 20-30cm branches of two fruit trees, cherry 'red light' and fruit plum 'Bungo', which contain full flower buds in the dormant period, and use 50μM GA 4 , 100μM GA 4 , 200μM GA 4 , 300μM GA 4 , 400μM GA 4 The hydroponic treatment was carried out; the branches of the fruit trees treated by hydroponic treatment were placed in the light incubator, and the germination rate of the branches of the fruit trees was counted after 10 days; the cultivation conditions were: 12 h day / 12 h night, and the temperature was 25±1.0 °C / 18 day ±1.0℃, light intensity 55 μmol·m ?2 ·s ?1 , the air relative humidity is 70%; the culture medium is changed every 2 days, and 2 mm of the base is cut off every time the water is changed to expose new stubble. To study its effect of releasing seasonal dormancy, the results showed that 200μM GA 4 The effect of relieving dormancy is the best, and the effect of too high or too low ...

Abstract

The invention relates to a method for getting rid of seasonal dormancy of fruit trees. The processing method for getting rid of the seasonal dormancy of the fruit trees includes the steps: (1) collecting fruit tree branches which are with full flower buds and in a dormancy period when chilling requirements satisfy one third, and carrying out water planting with GA4 solution; (2) putting the fruit tree branches through the water planting into an illuminating incubator and carrying out statistic on a germination rate of the fruit tree branches ten days later to confirm the dormancy state of the fruit tree branches. Compared with a current common dormancy breaking agent of lime nitrogen, the GA4 is small in toxicity, preparation of the solution of the GA4 and spraying the solution of the GA4 are simpler and easier than smearing of the lime nitrogen, and the dormancy breaking effect of the GA4 to the flower buds the fruit trees is better than that of the lime nitrogen. The GA4 is utilized to carry out the dormancy breaking processing on the fruit trees, so that the method for getting rid of the seasonal dormancy of the fruit trees has a good theory base and a good market prospect.

Description

technical field [0001] The invention relates to a method for releasing seasonal dormancy of fruit trees, which is specially used for releasing seasonal dormancy of fruit trees. Background technique [0002] The cooling requirement is the demand for low temperature during the dormancy period formed by plants during the long-term natural evolution process. Only when the cooling requirement is met can it be guaranteed to pass through natural dormancy smoothly. If the cooling requirement is insufficient, the plant cannot normally complete the whole process of natural dormancy , will cause growth and development disorders, even if the conditions are suitable, it will not germinate at the right time, or the germination will be irregular, and cause deformity of flower organs or severe abortion, affecting the yield and quality of fruits. In some areas in southern my country, the problem of "warm winter" has become increasingly prominent, and the cooling capacity of fruit trees canno...
