Highly active pollen suspension for spray pollination of Korla fragrant pear tree and its preparation and pollination method

Abstract

The invention belongs to the fields of fruit tree cultivation and pollination, and in particular relates to a high-activity pollen suspension used for spray pollination of Korla fragrant pear trees and a preparation and pollination method thereof. The highly active pollen suspension of the invention is made from purified water, white sugar, boric acid, calcium nitrate, xanthan gum and Korla fragrant pear pollen. Utilizing the technology of the present invention can effectively solve the problems such as low pollen utilization rate, poor pollen activity, poor pollination effect, and poor fruit setting due to the pollen not being evenly dispersed in the aqueous solution in the process of liquid spray pollination of Korla fragrant pear fruit trees, and ensures the best results in fruit trees. During the best pollination period, the pollination work can be completed in time and quickly, realizing efficient artificial pollination of pear trees, and greatly improving the efficiency and quality of pollination work. Through the production application test, the inflorescence fruit setting rate is increased from the original 38.9% to 71.5% after the technology of the invention is adopted, and the improvement rate reaches 83.8%, a good pollination effect is obtained, and the goal of high yield is realized.

Description

technical field

[0001] The invention belongs to the fields of fruit tree cultivation and pollination, and in particular relates to a high-activity pollen suspension used for spray pollination of Korla fragrant pear trees and a preparation and pollination method thereof. Background technique

[0002] Korla fragrant pear tree is a cross-pollination variety, and the fruit setting rate of self-pollination is extremely low (generally only about 3%). In production, it is often used to prepare pollination trees and artificial pollination to produce normal results, and pollination trees are often caused by bad weather. Pollen development is limited, thereby affecting pollination. Although the current liquid spray pollination is fast, because the relevant technology is still immature, it is easy to cause pollen to float on the water surface in groups, and the pollen utilization rate is very low, which can only reach about 30%. Conditions such as survival time in aqueous solution are...

Examples

Embodiment 1

[0048] A highly active pollen suspension for Korla fragrant pear tree spray pollination, made from the raw materials of the following weight:

[0049]

[0050] The preparation method is as follows:

[0051] (1) Weigh 2000g of pure water and boil it to 75°C, finely sprinkle 3g of xanthan gum powder into the hot water, and stir while adding it until the xanthan gum powder is completely dissolved to obtain a xanthan gum solution;

[0052] (2) After the xanthan gum solution is cooled, it is poured into 13000g of pure water and stirred evenly, then 1500g of white sugar is added thereto, and stirred to fully dissolve the white sugar to obtain an aqueous solution of sugar;

[0053] (3) Take 300g of sugar solution in a water bottle with a lid, add 30g of Korla pear pollen, tighten the bottle cap, then vibrate for 4 minutes at a frequency of 50 times / min, so that the pollen is fully and evenly dispersed in the sugar solution to make pollen Mother liquor;

[0054] (4) Pour the poll...

Embodiment 2

[0056] A pollination method based on highly active pollen suspension, comprising the following steps:

[0057] (1) Select the appropriate pollination period

[0058] Korla Fragrant Pear trees are pollinated at the beginning of full flowering, that is, when the flowering volume reaches 25%, and pollinate 3 times throughout the flowering period, and the pollination is completed at the end of full flowering when the flowering volume reaches 75%; pollination should be done when the anthers are pink; cloudy days can be carried out all day Pollination: Carry out before 12:00 am or after 18:00 pm on sunny days, avoiding adverse effects such as high temperature, dry hot wind, and strong wind.

[0059] (2) Selection of pollination varieties

[0060] Select varieties with large pollen quantity, meet flowering period, and benefit pear tree fruit setting and quality improvement as pollination trees.

[0061] (3) Pollen production

[0062] Collect the big bud bell flowers that are about...
