Embodiment Construction

[0019] 1. Collection of pollen

[0020] Select the pear flowers in the big bud stage, pick them up and bring them back in an ice box, peel off the anthers, and place them in a dry place at 25°C for a whole day and night. After the pollen is completely burst from the anthers, sieve them, remove the anther residues, and wrap them in Put it into a small bag folded with sulfuric acid paper and store it in silica gel for future use. The germination rate of the pollen was measured to be 74%.

[0021] 2. Screening of pear liquid pollination nutrient solution

[0022] 0.04% xanthan gum was used as the pollen dispersant, sucrose was used as the main osmotic regulator, boric acid and calcium nitrate were selected as the main components of the nutrient solution to promote pollen germination. Set the concentration gradient of sucrose to 13%, 15%, 17%, and 20%, respectively; the concentration gradient of boric acid to 0, 0.005%, 0.01%, 0.02%, 0.03%, and 0.04%; the concentration gradient o...

Abstract

The invention provides a method with effects of saving cost and improving efficiency for liquid pollination of pear tree, which belongs to the fruit trees production technical field. The method comprises the following steps: preparing a nutrient solution in full-bloom stage of pear flowers, adding 0.8g pure pollen in every liter of nutrient solution, spraying and pollinating by an electrostatic sprayer to achieve the purpose of artificial pollination. The pollination method has the advantages of simple operation, fast pollination speed, uniform powder injection, concentration, accuracy, pollen and manual work saving, low cost and the like, and solves the practical problems that pollen can not be uniformly dissolved in water in liquid pollination of fruit trees, pollen is easy to adhere with the wall of a container, pollen is obstructed a nozzle, uneven powder injection causes poor pollination effect and the real application of liquid pollination can not be realized for a long time. According to the invention, the new collected pure pollen (germination rate is 60%-80%) in current year required by per mu is 8-11g. In addition, the method of the invention is capable of increasing the moisture and nutrient of pistil stigma and prolonging the fecundation time of stigma pollination, and the fruit quality can not be affected by increasing the fruit setting rate.

Description

1. Technical field [0001] The invention relates to a pear tree liquid pollination method which saves costs and increases efficiency, and belongs to the technical field of fruit tree production. 2. Background technology [0002] Pear is a self-pollination non-fertile fruit tree. In production, pollination trees must be planted or artificially assisted pollination to obtain corresponding yield and quality. Planting pollination trees mainly uses the pollination ability of insects for natural pollination. Although it saves labor and labor, it is easily affected by the weather and causes poor pollination and fertilization. In recent years, more and more pear orchards have adopted artificial assisted pollination. Although the method of artificial point pollination in the artificial assisted pollination method has strong selectivity, high accuracy rate, and small pollen consumption, it has a short operation time, requires a lot of labor, and has high production costs. In addition...
