Method for improvement of calyx leaving rate of fruits of Nanguo pears

Abstract

The invention provides a method for improvement of the calyx leaving rate of fruits of Nanguo pears. A 200-fold PBO solution is sprayed on all flowers at the full-bloom stage, and a 200-fold calcium-boron mixed solution is sprayed on all young fruits at the fading stage; the 200-fold PBO solution is prepared by dissolving PBO in the proportion of 1 g PBO to 200 ml water; the 200-fold calcium-boron mixed solution is prepared by dissolving CaCl2 and boric acid in the proportion of 1 g CaCl2 to 1 g boric acid to 200 ml water. According to the method for improvement of the calyx leaving rate of the fruits of Nanguo pears, specific chemical agents are sprayed on flower organs at the full-bloom stage and the fading stage of the Nanguo pears respectively, so that not only is the calyx leaving rate of the fruits improved, but the stone cell content is reduced, and the internal and external qualities of the fruits are improved.

Description

technical field [0001] The invention relates to a method for removing calyxes from fruits, in particular to a method for improving the rate of removing calyxes from fruits of Nanguo pear. Background technique [0002] The fruit of Nanguo pear has many characteristics such as delicate pulp, soft and juicy, and strong aroma. In pear cultivation, fruit sepal persistence is a common phenomenon in fruit development, and the proportion of fruit with sepal persistence in Nanguo pear is relatively high. The persistence of sepals will lead to rough fruit surface, darker color, thicker flesh, increased number of stone cells and decreased sugar content in fruit, resulting in poor fruit quality. Pear fruit calyx removal methods include artificial calyx removal and chemical reagent removal. Artificial calyx removal has the problems of high labor intensity and high labor costs. Although existing chemical reagents can improve the calyx removal rate, they are also harmful to pear fruit qua...
