Embodiment 1

[0020] Collection of pollen and preparation of crude solution.

[0021] The experiment was carried out in the Pear Resource Garden of the Institute of Horticulture, Jiangsu Academy of Agricultural Sciences (Nanjing City). The variety is fragrant. Methods as below:

[0022] Pick the pear flower buds when they are in bud and wait for release. After removing the flowers, they are directly placed in an incubator at 20-25°C to dry to form powdered medicine for later use.

[0023] Take the powdered medicine and immerse it in 1.5 times the volume of water, fully stir the powdered medicine suspended in the water, pass the sample sieve to remove impurities, and form a coarse pollen solution.

Embodiment 2

[0025] In the preparation of coarse pollen solution, the influence of different pore sizes on the pollen grains in the solution after filtering through the sample sieve

[0026] Divide the same powdered medicine into four groups on average, immerse in the same volume of water, stir the powdered medicine suspended in the water well, filter them with sieves with apertures of 0.75mm, 0.5mm, 0.25mm and 0.12mm respectively, and then Each group was sampled ten times, each time 10 μl was smeared on a glass slide, the number of pollen grains in the field of view was observed under an electron microscope, and the average value was calculated. The observation data of each group are recorded in Table 1.

Embodiment 3

[0032] Effects of Calcium Spraying During Flowering Period on Fruit Shelf Life

[0033] The experiment was carried out in the pear resource nursery of the Institute of Horticulture, Jiangsu Academy of Agricultural Sciences (Nanjing City), and the row spacing of pear trees in the nursery was 3m×4m. Variety: Choose 8-year-old Cuiguan pear.

[0034] experiment method

[0035] Spray Cuiguan pear with 0.01, 0.02, 0.03, 0.04, 0.05 g / L chelated calcium solution at the flowering stage, harvest the fruit when it is normally mature, and observe it on the shelf at room temperature. The results are reported in Table 2.

Abstract

The invention relates to pear pollination solution, which comprises pollen transferred for pear trees. The pear pollination solution is characterized in that pear pollen is suspended in mixed liquor, the mixed liquor is composed of accelerator, colorant, spreader and water, the accelerator can be composed of cane sugar, boric acid, chelate calcium and urea, or composed of cane sugar, borax, chelate calcium and urea, the colorant is food colorant, the spreader is tween-20, and the mixed liquor comprises, in weight percentage, 6% of white sugar, 0.002% of the boric acid or borax, 0.003% of the chelate calcium, 0.005% of the urea, 0.001% of the food colorant, 0.01% of the tween-20, and the balance of the water.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, and more specifically relates to a pear pollination solution and a preparation method and application thereof. Background technique [0002] Many fruit trees such as apples, pears, plums, etc. have the characteristics of self-pollination and low fruiting rate. In actual production, it is necessary to rationally allocate pollination trees to promote fruit setting and obtain due yield and quality. However, poor pollination, low fruit setting rate, and reduced yield and quality are often caused by improper pollination varieties, bad weather conditions during flowering period that affect insect pollination, etc. Therefore, artificial assisted pollination has become an indispensable work in actual production. Practice has proved that only when there are enough pollen grains on the stigma of the pistil can the successful completion of pollination and fertilization be ensured, because a large amoun...
