Chinese goosebeery florescence-meeting water culture method

Abstract

The invention discloses the hydroponics for the encountance of kiwi fruit in flower period and relates to the encountance method in flower period, which comprises the following steps: i.the start time of water planting of the male plant is 45-55 days earlier than the blooming of the female plant; ii. taking the thrifty and disease and pest free branch in the middle or lower part of the yearly male kiwi fruit according to the time in i., the number of plump sprout in each ear is 2-4, the length of the branch is 13-17cm, shearing the low cut fullmouthly, shearing the up cut in the distance of 0.8-1.2cm from the sprout, immersing the ear in the 400 times MS culture medium with the value of the pH 5.6-5.8, with the immersion depth 1 / 2-5 / 6 of the era length, then water planting in the tissue culture room with the temperature between 18 and 25 DEG C, the relative humidity 70-100% and the illumination intensity 1800-2200 LuX, iii. culturing the ear in the clean water 25-35 days later, changing the water regularly, iv. make the fresh male flower encounter with female flower when the kiwi fruit blooms.

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
