Plant growth regulator and preparation method as well as application thereof

Abstract

The invention belongs to the technical field of fruit tree production, and relates to a plant growth regulator and a preparation method as well as application thereof. The plant growth regulator comprises lanolin as a matrix and 2.5-3 percent of GA(3+4+7), 2-5 percent of calcium nitride, 2.2-2.8 percent of boric acid, 1-5 percent of potassium nitride and 290-310 ppm of CCPU serving as ointment. The growth regulator is convenient to manufacture, the use method is simple, the nutrients required for development of fruits is fully guaranteed, the efficacy is lasting, the single fruit weight of pears is obviously improved, the weight is increased by 36.6 percent, the inherent quality of the fruits is not reduced, and the appearance quality is improved to a certain extent. Compared with the common plant growth regulators on the market, the plant growth regulator has the advantages that the single fruit weight of the pears is obviously increased, the content of mineral elements of the fruits is increased, and the problems of shorter effective action time and short shelf life of the pears after treatment of other plant growth regulators are solved.

Description

technical field [0001] The invention belongs to the technical field of fruit tree production, and relates to a plant growth regulator and its preparation method and application. Background technique [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. However, due to the short fruit development period of some varieties, and the influence of adverse factors such as rainy season and insufficient sunshine, there are often problems such as small fruit weight, low per unit yield, low uniformity, poor appearance quality, and low commerciality. For example, the golden pear, which is widely planted in many areas of our country, generally has oblate fruit, with yellow-green skin when ripe, and turns golden yellow after a little storage. Soft and juicy, white flesh, very few stone cells, high edible rate, sweet and fragrant, unique flavor, excellent quality, but in recent years...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the shortcomings of the existing method for promoting pear fruit expansion, which consumes a lot of manpower and material resources, the effect is not obvious, the drug effect time is short, and the treated fruit is not resistant to storage and the shelf life is short, and provides a plant growth regulator
