Abstract

The invention provides a method for improving the rate of fruit without sepal, belonging to the technical field of fruit tree production. The sepal removing agent is composed of 6000 times of flusilazole emulsifiable concentrate and 300 times of PBO (poly(p-phenylene-2,6-benzoxazole)). The application method comprises the steps of spraying the 6000 times of flusiazole emulsifiable concentrate in the period when pear flower gets white and then spraying the 300 times of PBO at bloom stage. The combination and application method of the two reagents with different concentrations are simple and easy, key links of pear cultivation technique are fully utilized, sterilization and disease prevention are carried out in production, and fruit sepal removing rate is synchronously carried out in the technical processing of regulating fruit growth and development, thus saving labour force and time cost, obviously increasing the rate of pear without sepal and obviously improving appearance quality of fruit.

Description

1. Technical field [0001] The invention relates to a method for improving the calyx removal rate of pear fruits, which belongs to the technical field of fruit tree production. 2. Background technology [0002] Pear fruit has high nutritional value, crisp and juicy, strong flavor, rich in sugar, acid, minerals, vitamins, etc., and is deeply loved by consumers. In recent years, with the improvement of living standards, the quality of pear fruit has attracted more and more attention from consumers, especially the appearance quality as the first impression is often the key factor that determines consumers' desire to buy. Significantly improve the commerciality of pear fruit, improve market competitiveness, thereby bringing higher economic value. However, due to the characteristics of pear fruit itself, the sepals of some pear varieties such as 'Korla Fragrant Pear', 'Dangshansu Pear' and 'Laiyang Chili' are persistent at the top of the fruit. Commonly known as "gong pear". ...
