Castration-free compartment isolation bagging crossbreeding method for lagerstroemia plants

Abstract

The invention discloses a castration-free compartment isolation bagging crossbreeding method for lagerstroemia plants. The method comprises the following steps of (1) manufacturing a lagerstroemia male and female stamen compartment isolator; (2) bagging; (3) pollinating; and (4) dismantling. According to the lagerstroemia male and female stamen compartment isolator, a fixing device is arranged to conduct two-section clamping on pedicels, and supporting and fixing are provided for the lagerstroemia male and female stamen compartment isolator; the male and female stamen isolator is linked with the fixing device to seal and fix pedicels, and the male and female stamen isolator is driven to seal and isolate flower buds at the same time; an adjusting assembly and a clamping element are arranged on the male and female stamen isolator, the male and female stamen isolator and an isolator cover can be adjusted and fixed according to the sizes and distances of flower buds and stigmas, and finally the lagerstroemia male and female stamen compartment isolator is fixed to a pedicel so that the flower buds can be sealed and isolated.

Description

Technical field[0001]The present invention belongs to the field of plant cultivation technology, in particular, involving a pulsating bag hybrid breeding method for Ziwei belly.Background technique[0002]"Hubei Agricultural Science" November 2010, No. 49, No. 11, recorded Wang Ruiwen, Yang Yanling and other research reports on "Research on the Change of Ziwei Pollen Valuation and Standard", the research report is as follows: Ziwei in the morning 4:30 left and right lap loose, the front is extended, the top is green non-probable; 5: 30-6: 00 petals began to expose anthers; 7: 00-7: 30 petals completely unfolding the head with a small amount of transparent mucus; 8: 00- At 9:30, a large amount of mucus was started, and it was observed on the front of the pillar; 16:00 in the afternoon gathered, the stretches were still standing out. The flowering next day, the flower is completely collected, the front of the pillar is covered with yellow pollen, the petals are shallow, the child is ble...
