Yangtao actinidia florescence-meeting cuttage method

Abstract

The invention discloses the cuttage method for the meeting of kiwi fruit in flower period and relates to the plant meeting method in flower period, especially to the kiwi fruit meeting method in flower period. The invention comprises the following steps: (i)cuttage time, the start time of cuttage of the male plant is 45-55 days earlier than the flower time of the female plant; (ii) preparing slotter; (iii) cutting the cuttage-ear; (iv) the management after the cuttage, removing the top when the new ear grows out; (v) making the fresh male flower meet with that of female when the kiwi fruit blooms. The invention possesses the following characteristics: the large quantity of pollen, which guarantees enough pollen supply; the change of flower period, the meeting in the flower period when the flower period varies widely can be realized by controlling the time artificially; the wide range of the use, it can be used in many basal kiwi fruit production area and can also be used to solve the problem of no-meeting in the flower period of other plants.

Description

technical field [0001] The invention relates to a method for meeting plants at flowering stages, in particular to a method for meeting kiwi fruit at flowering stages. Background technique [0002] Plant cross-breeding is a quick and effective method to create new germplasm; however, when crossing, it often encounters the problem that the flowering time of the parents is different, which causes the flowering time to not meet. The methods used to solve this problem in the past were collecting pollen in different places, storing pollen, changing the environmental conditions (temperature, light, humidity) of the hybrid parents, and treating with chemicals. [0003] At present, the conventional method to solve the encounter of kiwifruit flowering period is: [0004] 1. Picking powder from different places [0005] Due to the different flowering periods in different regions, generally the flowering period of kiwifruit planted in the south is relatively early, and the flowering p...

AI Technical Summary

Problems solved by technology

[0013] 1. Collecting pollen in different places can be used when the flowering period in different places is not much different, but it is difficult to solve the problem of meeting when the flowering period is very different

[0014] 2. Storing pollen, this method is labor-intensive and time-consuming, and the pollen viability is relatively poor in the next year, resulting in a decrease in the success rate of hybridization and affecting the pollination and fruit-setting rate

[0015] 3. Changing the environmental conditions, this method has a large workload, high cost, and difficult implementation, and the time for changing the flowering period is relatively short, and the application range is narrow

[0016] 4. Chemical treatment, the time to change the flowering period is relatively short, and the application range is narrow
