Preparation and use method of kaolin suspending agent for promoting quick full rust of pear fruit surfaces

Abstract

The invention discloses a preparation and use method of a kaolin suspending agent for promoting quick full rust of pear fruit surfaces, and the formula comprises the following components in parts by weight: 1-2 parts of ultra-white kaolin, 3-5 parts of white granulated sugar and 24-50 parts of purified water. The preparation of the kaolin suspending agent for promoting quick full rust of the pearfruit surfaces comprises the following steps: within a period from a rapid expansion period 15 days after blossom fall of the fruits to a slow increase period of the fruits, smearing and covering thewhole fruit surface of the rust-sensitive green-peel pear so that rapid and comprehensive rust sensing of peels is promoted, the full rust rate and the coloring consistency of fruits of the rust-sensitive pear variety are greatly improved, the problem that a large number of green-brown alternate'flower-face 'fruits occur in bare fruit cultivation of the rust-sensitive pear variety in rainy and high-humidity areas in the south can be effectively solved, and therefore the appearance quality and the commodity performance of the rust-sensitive green-peel pear variety are improved, and the economicbenefits of rust-sensitive green-peel pear variety cultivation are increased.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a method for preparing and using a kaolin suspending agent for promoting rapid rust on pear fruit surfaces. Background technique [0002] Rust-sensitive green-skinned pear varieties, the fruit surface is often brown due to rust, and part remains green, forming a large number of brown-green "painted face" fruits, which affects the appearance quality of the fruit and reduces the product performance and sales price. At present, the production of rust-sensing green-skinned pears mainly adopts two bagging methods to prevent or reduce the occurrence of fruit rust and improve the consistency of peel color. [0003] However, the traditional bagging method requires a large amount of paper bags, high material cost, and inconvenient application, which increases the cultivation cost of rusty green-skinned pears. In addition, it is difficult to implement bagging measures on a l...

[0003] However, the traditional bagging method requires a large amount of paper bags, high material cost, and inconvenient application, which increases the cultivation cost of rusty green-skinned pears. In addition, it is difficult to implement bagging measures on a large scale due to the rainy days in the suitable bagging period in the south. limited use
