Method for improving loquat fruit quality

Abstract

The invention discloses a method for improving loquat fruit quality, and relates to the technical field of crop cultivation. The method comprises the following steps: S1, fertilizing is carried out, wherein an organic human and animal fertilizer and a composite fertilizer are applied in soil during a flower bud germination stage; CaCl2 is sprayed during a full-bloom stage; a chitin fertilizer is applied in soil during a young fruit stage; and a potassium magnesium sulfate fertilizer is applied in soil before fruit harvesting; S2, pest controlling is carried out, wherein pesticide is sprayed to leaves once or twice respectively at 25-35 days after loquat tree flowering and 3-5 days before loquat fruit bagging; and S3, fruit thinning and bagging are carried out, wherein 2-3 fruits are left on each bunch for a large-fruit type, 3-5 fruits are left on each bunch for a medium-fruit type, and 5-7 fruits are left on each bunch for a small-fruit type; and bagging is carried out immediately after fruit thinning. The method is simple, highly efficient, pollution-free, and green and environment-friendly. With the method, single fruit average weight, edible rate, soluble solid content, soluble sugar content, and vitamin C content are improved. Single fruit average titratable acid content is reduced. Also, the fruits have glossy and bright appearance and good tastes. With the method, the market value of the fruit is improved, and economic benefit is improved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for improving the quality of loquat fruit. Background technique [0002] As a common fruit, loquat is also called Luju, Luzhi, Jinwan, Yanguo, and Jiaozi. Because its leaves are very similar to pipa, it is called loquat. The fruit tree has certain ornamental value. Loquat is not only delicious and nutritious, but also has the effects of nourishing the lungs, clearing heat and invigorating the stomach, diuretic and nourishing and strengthening the body. It has a good auxiliary effect on promoting digestion, relieving heat, moistening the lungs and relieving cough, and preventing colds; Trace elements such as iron, magnesium, and potassium are essential elements for the human body, and the carotene contained in it ranks third among all fruits, and is deeply loved by consumers. [0003] However, in the market in recent years, due to the influence of ec...

Problems solved by technology

[0005] After searching, disclose a kind of method of improving loquat fruit quality as Chinese Patent Publication No. CN101982059, it has adopted the method for paving reflective film and spraying indole, although also reached to increase average single fruit weight, edible rate, solid edible Soluble matter reduces the purpose of titratable acid content, but its technology is relatively cumbersome; the reflective film used is aluminized polyester reflective film, a large number of repeated use of this reflective film will inevitably pollute the environment, and this reflective film The film is more expensive than conventional bagging. Although it can improve fruit quality to a certain extent, it cannot be used and recycled for a long time, which wi...
