Method for bagging-free cross pollination of cherry blossom

Abstract

The invention discloses a method for bagging-free cross pollination of a cherry blossom. The method comprises the first step of arranging a centrifugal tube orifice for filling pollen close to a stigma, dipping the pollen with an eye liner brush and applying the pollen on the surface of the pistil stigma gently till the surface of the stigma is covered with pollen; the second step of setting pollination time: completing pollination in time after emasculation in the morning from 8:00 to 10:00 or in the afternoon from 4:00 to 6:00; the third step of scaffold erection: erecting a support frame onthe periphery of a stock tree after the pollination of the whole stock tree; the fourth step of insect-proof net covering: covering a 40-60 mesh insect-proof net on a support frame. A pollen storagemethod is provided, and solves the problem that a male parent flowering period is earlier than a female parent flowering period in the problem that the male parent flowering period and the female parent flowering period do not meet in the cross pollination. The maturing rate of the cross pollination is improved by reasonable pollination methods and steps. Due to the fact that the support frame iserected on the periphery of the stock tree after the pollination, and the insect-proof net covers the tree, the process of bagging and bag removing is eliminated, the workload of the cross pollinationis greatly reduced, and the working efficiency of the cross pollination is improved. Birds are prevented from eating hybrid fruit.

Description

technical field [0001] The invention belongs to the field of plant breeding, and relates to a method for cross-pollination of cherry blossoms without bagging. Background technique [0002] Cherry blossoms refer to the collective name of plants with ornamental value in the Rosaceae (Rosaceae) genus Cerasus. It is an important woody ornamental plant in early spring. When the flowers bloom, the trees are full of flowers. From a distance, they look like clouds and clouds, and they are colorful. In the season of falling flowers, the fallen flowers are colorful. In recent years, with the improvement of people's living standards and the vigorous development of the flower viewing economy, cherry blossom viewing in early spring has become one of the important items for people to travel in early spring. [0003] my country is a country with large resources of cherry blossoms, and cherry blossom cultivation has a long history. As early as the Qin and Han Dynasties, there are historic...

Problems solved by technology

This method works better on other plants with large flowers, thick branches and long flower stalks. However, cherry blossoms have small flowers, thin branches and short flower stalks, which makes bagging difficult and the effect is not good. After the bag encounters wind and rain, after the wind and rain, the pollinated pistils or young fruits are easily injured or dropped due to shaking and friction, resulting in a large loss of hybrid fruits
