Artificial pollination method of apple trees

Abstract

The invention discloses an artificial pollination method of apple trees. The method comprises steps as follows: (1) preparation of pollen; (2) preparation of a petal extracting liquid; (3) preparation of a sepal extracting liquid; (4) preparation of a pollen pollination liquid; (5) artificial pollination. The expiry date of the uniquely prepared pollen pollination liquid is as long as two days at the normal temperature, the vitality of pollen in the period is not reduced obviously, the problem that the pollination liquid is required to be prepared many times in the existing methods is solved, the labor intensity is reduced, meanwhile, the pollination activity intensity of bees and other insects can be enhanced, the problem that flowers cannot be covered during spraying is solved, the final apple setting rate is 98% or above, the nutritional value of cultivated apples is also increased, the planting benefit is greatly improved, besides, the method is simple, the pollen consumption is low, the cost is lower, and the method has good promotional value.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to an artificial pollination method for apple trees. Background technique [0002] Apple belongs to the genus Apple of the Rosaceae Apple subfamily. The fruit is spherical and the flesh is crisp and sweet. It is a common fruit and the most common fruit. It is rich in vitamin nutrition and is one of the four major fruits in the world (apple, grape, citrus and banana ) crown. Apples are usually red, but yellow and green are also available. Apples have been cultivated in China for more than 2,000 years, and there are thousands of varieties, which are divided into wine varieties, cooking varieties, and end food varieties. The size, color, aroma, smoothness, brittleness, flavor and other characteristics of the three types of varieties are all different. Many varieties are high in sugar, medium in acidity and low in tannins. In addition to being eaten raw, apples are also cooked in...

Problems solved by technology

[0003] Most of the existing artificial pollination methods are artificial point pollination, that is, the pollen is directly applied to the style of the female flower by a brush or a soft brush. This method has the disadvantages of high labor cost, time-consuming and labor-consuming, and a lot of pollen consumption. People have explored and tried liquid pollination, that is, dissolving pollen in a liquid solvent, and then spraying it on the stigma of female flowers. The liquid pollination technology is still immature, and there are still problems such as poor suspending ability of the nutrient solution, uneven dispersion of pollen, and easy swelling and death in the nutrient solution, and the prepared pollen solution needs to be used up in a short time, usually within 5 hours , otherwise the pollen loses its vigor and has no use value, which also increases the tediousness of the preparation work during the pollination period, and at the same time inevitably causes a certain degree of waste of pollen

In addition, although the liquid pollination method is more convenient, the flowers are relatively dense during the blooming period, and it is impossible to ensure that the flowers are covered when spraying, which will still cause some flowers to fail to pollinate, which is not conducive to improving the pollination rate.

[0004] Before the apples enter the flowering period, it is usually necessary to perform flower thinning operations to reduce unnecessary nutrient loss and increase the quality of the fruit. During flower thinning, a large number of useless flowers will be produced, and many flowers will wither when apple trees grow naturally. Currently, there are few Ways to make good use of such flowers
