Pollution-free mother pear agent for improving fruit setting rate

Abstract

The invention discloses a pollution-free mother pear agent for improving the fruit setting rate, which comprises effective active components, wherein the effective active components comprise an active component A and an active component B, the weight ratio of the active component A to the active component B is 20: 1 to 12: 1, the active component A is one of propiconazole, flusilazole, tebuconazole and diniconazole, the active component B is gibberellic acid, the weight ratio of propiconazole to gibberellic acid is 20: 1 to 12: 1, and the weight ratio of flusilazole to gibberellic acid is 15: 1 to 10: 1. According to the pollution-free mother pear agent for improving the fruit setting rate, a formula combination is obtained through experiments, the formula combination has good synergistic and lasting effects within a certain range, the effect is higher than that of a single agent, the purpose of removing sepals on the top of pear fruits is achieved, and the calyx removal rate of crisp pears is obviously increased. Meanwhile, the appearance, stem length and fruit shape index of pear fruits are obviously improved, and the fruit setting rate of pear trees is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a pollution-free mother pear agent for improving fruit setting rate. Background technique [0002] Female pear preparation, officially named pear fruit calyx remover, is a preparation for improving the quality of pome fruit. After use, it can effectively promote the shedding of sepals, realize "male pears into female pears", improve the quality of pome fruit and increase revenue. [0003] Due to the characteristics of pear fruit itself, some pear varieties such as 'Korla Fragrant Pear', 'Dangshansu Pear' and 'Laiyang Chili' have sepals that persist at the top of the fruit. In production, the fruit with persistent sepals is commonly called "Gongli", the fruit of "Gongli" has persistent sepals, protruding calyx ends, and irregular fruit shape, and is accompanied by problems such as increased stone cell content in the fruit, reduced sugar content, and weakened flavor.

[0003] Due to the characteristics of pear fruit itself, some pear varieties such as 'Korla Fragrant Pear', 'Dangshansu Pear' and 'Laiyang Chili' have sepals that persist at the top of the fruit. In production, the fruit with persistent sepals is commonly called "Gongli", the fruit of "Gongli" has persistent sepals, protruding calyx ends, and irregular fruit shape, and is accompanied by problems such as increased stone cell content in the fruit, reduced sugar content, and weakened flavor. In addition, the top of the fruit The persistent sepals also provide a more favorable place for the habitat of diseases and insect pests. Therefore, the acceptance of "male pears" by fruit consumers at home and abroad is low, and the market price is significantly lower than that of "female pears" whose sepals have fallen off, which eventually leads to economic losses. The benefits are low, and the "male pear" phenomenon of persistent sepals in the fruits of these major cultivars has become one of the outstanding problems that my country's pear industry needs to solve urgently

[0004] In the current production, the method of manually cutting calyxes is often used to solve the problem of persistent sepals in pome fruit. Although this method is a good way to reduce the rate of "male pears", field operations are labor-intensive and time-consuming, and labor costs increase. It is not suitable for large-scale intensive production, and a small scar is often left on the top of the fruit after the calyx is cut, which affects the appearance quality of the fruit to a certain extent. Technology, some technicians try to improve the rate of pear fruit decalyx by spraying methods including paclobutrazol, ethephon or other mixed reagents. Although these chemical decalyx methods have the advantages of saving labor and labor, the decalyx effect is not obvious. Or mixed reagents are difficult to configure and use, and even some reagents can produce side effects. Therefore, there is no suitable medicament treatment so far to solve the problem of persistent fruit sepals
