Problems solved by technology

[0004] At present, for the pollination of tea trees, artificial pollination is used, that is, the collected pollen is artificially placed on the emasculated flowers with a tool such as a brush. The work efficiency of this pollination method is relatively slow, and it is a waste of labor; In addition, the nutrients are consumed after being pollinated, and the nutrient solution needs to be sprayed separately, which is troublesome to operate

Embodiment 1

[0026] A kind of pollination method that improves artificial pollination efficiency of tea tree, specifically comprises the following steps:

[0027] (1) Pollen collection: 2 days before pollination, pick the flowers to be released from the male parent tea tree;

[0028] (2) Pollen drying: place the picked flowers on a tray with absorbent paper laid on the bottom of the tray, put the tray in a drying oven, and dry at 25°C for 20 minutes;

[0029] (3) pollen collection: sieve the dried flowers, the aperture of the sieve is 2.5-3.0mm, to obtain pollen;

[0030] (4) pollen dilution: put the pollen into clear water with 800 times the pollen mass, and add a nutrient solution with 10 times the pollen mass to the clear water, stir well to obtain the pollen dilution;

[0031] (5) Pollen pollination: the pollen dilution is put into the sprayer, and the flowers on the female parent tea tree after emasculation are sprayed for pollination;

[0032] (6) Bagging: the flowers after pollina...

Abstract

The invention discloses a pollination method for improving the artificial pollination efficiency of tea trees in the technical field of tea tree pollination. The pollination method comprises the following steps: (1) pollen collection; (2) pollen drying; (3) pollen collection; (4) pollen dilution; (5) pollen pollination; (6) bagging; and (7) bag removal. By adding a nutrient solution, calcium nitrate and potassium nitrate, potassium and calcium sources can be supplemented to floral organs; ammonium dihydrogen phosphate can supplement a phosphorus source for floral organs, so that the consumption of nutrients in the flowering phase is effectively supplemented, and the pollination quality is improved; According to the pollination method, pollen, the nutrient solution and clear water are mixed, a pollen diluent is directly sprayed to flowers on castrated female parent tea trees through a sprayer to complete pollination, manual point pollination one by one is not needed, meanwhile, nutrientsubstances are supplemented, and the efficiency of artificial pollination is improved.

Description

technical field [0001] The invention relates to the technical field of tea tree pollination, in particular to a pollination method for improving the artificial pollination efficiency of tea trees. Background technique [0002] Tea tree is a shrub or small tree of the family Theaceae, Camellia, with glabrous twigs. Leaves leathery, oblong or elliptic. The leaves of the tea tree can be used to make tea (different from the tea tree), the seeds can be used to extract oil, the material of the tea tree is fine and dense, and its wood can be used for carving. The distribution is mainly concentrated between 16 degrees south latitude and 30 degrees north latitude. Tea trees like warm and humid climates. The buds start to germinate when the average temperature is above 10°C, and the optimum temperature for growth is 20-25°C; the annual precipitation should be above 1000 mm; Sun-loving and shade-tolerant, it is suitable for growing under diffuse light; its life is divided into seedli...
