Problems solved by technology

This approach cuts off the nutrient transport channel of the branches, so that the photosynthetic products produced by the leaves are used more for the formation of flower buds, but this measure will cause the tree to weaken, reduce the tree's ability to resist diseases and stress, and easily cause diseases such as rot

Abstract

The invention discloses a method for inducing early maturity of pears in a seedless mode. The method comprises the steps that in the full-bloom stage, flower buds are handled by using inductive agents, and fruit stems are smeared with GA4+7 soft paste on the twentieth day to twenty-fifth day after the full-bloom stage; the inductive agents are GA4+7 solutions, and the concentration is 500-750 mg / L; in the GA4+7 soft paste, the mass fraction of GA4+7 is 2.0 percent to 3.0 percent. The method can effectively induce seedlessness of the pears, and the early maturity of fruits is promoted. The obtained seedless fruits are free of abnormity, good in appearance, large in size, small in fruit core, high in edible rate and better in flavor, and the mature period is advanced by about 18 days relative to that of pollinated fruits. In addition, the method is easy and convenient to operate and low in requirement for equipment, cost is greatly lower than that of hand pollination, large-scale operation can be achieved, and the method is suitable for commercial orchards.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for inducing seedless and precocious pears. Background technique [0002] Pear is a plant of the genus Pyrus in the family Rosaceae, a perennial deciduous fruit tree. Pears have rich nutritional value, but some pear varieties have low edible rate because of their many seeds and large fruit hearts. In addition, pears are self-incompatible fruit trees, which require pollination trees or artificial pollination to bear fruit. However, artificial pollination requires a lot of work, and the cost of purchasing pollen is also high. Therefore, if the seedless pear fruit is successfully cultivated, it can not only reduce the core ratio and increase the edible rate, but also eliminate the need to purchase pollen, which greatly reduces the production cost. [0003] Fruits can also become seedless under natural conditions, such as frost damage and high temperature ...
