Nutrient solution for fruit tree liquid pollination, and preparation and application methods thereof

Abstract

The invention relates to a nutrient solution for fruit tree liquid pollination, and preparation and application methods thereof. Every 100 parts by weight of the nutrient solution comprises the following components in parts by weight: 0.2-0.5 part of trehalose, 7.5-12.5 parts of sucrose, 0.075-0.1 part of agar, 0.05-0.08 part of elsholtzia phenol and the balance of water. The preparation method of the nutrient solution comprises the following steps: dissolving, sterilizing, and filling and storing. An ultralow-volume sprayer spraying mode is adopted to perform liquid pollination; and before spraying, 0.1-1.0 part by weight of pollen is added to every 100 parts by weight of the nutrient solution. The nutrient solution for fruit tree liquid pollination solves the 4 problems capable of influencing the liquid pollination success rate: the pollen swells when contacting water; the pollen can not be dispersed uniformly in the liquid; the sprayed and dispersed pollen has too large mist particle diameter; and the pollen germinates and dies in water. The nutrient solution for fruit tree liquid pollination can enhance the fruit tree pollination success rate, and has stable pollination effect.

Description

technical field [0001] The invention relates to the technical field of fruit tree pollination, in particular to a nutrient solution for fruit tree liquid pollination and methods for preparing and using the same. Background technique [0002] Pollination between different varieties of plants or between different plants is also called cross-pollination. In the process of fruit tree cultivation, artificial pollination is usually used to complete cross-pollination. The pollination effect directly affects the fruiting capacity of fruit trees. [0003] At present, artificial pollination methods are as follows: [0004] 1) Pointing method: Use a brush and or the valve core to roll a little forward on the bamboo stick or iron wire, dip the pollen on the stigma of the pistil and wipe it lightly. Every time you dip the pollen, you can transfer about 5 to 10 flowers; you can also use pollen Manual pollination with a gun can increase the efficiency by more than 5 times; the pollination...

AI Technical Summary

Problems solved by technology

[0009] The invention provides a nutrient solution for fruit tree liquid pollination and its preparation and use method, which solves the following four problems affecting the success rate of liquid pollination: one is that the pollen swells in water; the other is that the pollen is not uniformly dispersed in the liquid; The diameter of the fog particles after the pollen spray is dispersed is too large; the fourth is that the pollen germinates and dies in the water; it can improve the success rate of pollination of fruit trees, and the pollination effect is stable
