Problems solved by technology

Among them, the total sugar, reducing sugar, soluble solids and vitamin content of loquat trees covered with aluminum foil and aluminum film were higher than those of the control group, but their total acid content was also significantly higher than that of the control group. The reason may be that the...

Embodiment 1

[0022] 1. Take the high-acid variety 'Jiefang Zhong' as an example.

[0023] 2. Time for laying reflective film: from the first physiological fruit drop of loquat fruit to the fifth day after the second physiological fruit drop.

[0024] 3. The location of the reflective film: the drip line is covered with reflective film (aluminized polyester reflective film).

[0025] 4. Spraying time of indole ripening ester: Judging by the size of the fruit, it can be sprayed when the transverse diameter of the fruit is 2.0-3.0cm and the longitudinal diameter is 3.0-4.0cm. (Fujian, Guangdong and other places can spray indole from March 9th to April 5th).

[0026] 5. Concentration of sprayed indole: 250mg / L.

Embodiment 2

[0028] 1. Take the loquat variety "Jiajiao" as an example.

[0029] 2. Time for laying reflective film: from the first physiological fruit drop of loquat fruit to the 6th day after the second physiological fruit drop.

[0030] 3. The location of the reflective film: the drip line is covered with reflective film (aluminized polyester reflective film).

[0031] 4. Spraying time of indole ripening ester: Judging by the size of the fruit, it can be sprayed when the transverse diameter of the fruit is 2.0-3.0cm and the longitudinal diameter is 3.0-4.0cm.

[0032] 5. Concentration of sprayed indole: 200mg / L.

Embodiment 3

[0034] 1. Take the loquat variety 'Xiangzhong 10' as an example.

[0035] 2. Time for laying reflective film: from the first physiological fruit drop of loquat fruit to the 7th day after the end of the second physiological fruit drop.

[0036] 3. The location of the reflective film: the drip line is covered with reflective film (aluminized polyester reflective film).

[0037] 4. Spraying time of indole ripening ester: Judging by the size of the fruit, it can be sprayed when the transverse diameter of the fruit is 2.0-3.0cm and the longitudinal diameter is 3.0-4.0cm.

[0038] 5. Concentration of sprayed indole: 180mg / L.

Abstract

The invention provides a method for improving the quality of loquat fruits. In the method, a light reflection film is laid and ethylchlozate is sprayed. The method can obviously lower the organic acid in the loquat fruit, and improves the soluble solid state material in the fruit and the fruit quality. The light reflection film is laid and ethylchlozate is sprayed in an orchard to obviously lower the titratable acid (TA) in the fruit and improve the content of the total soluble solid (TSS) of ripening pulp, and the weight of the single fruit of the ripening fruit, thus obviously improving the ripening fruit quality of the loquat.

Description

technical field [0001] The invention relates to a method for improving the quality of loquat fruit, which belongs to the field of agriculture. Background technique [0002] The content and components of fruit organic acids are one of the important factors that determine the quality of fruit flavor, and one of the main problems in my country's loquat industry is that the fruit acidity is too high. Therefore, acid reduction is of great significance to improve the quality of loquat fruit and harvest early. [0003] Wu Deyi et al. [Effects of spraying indole ester and ammonium molybdate on increasing sugar and reducing acidity of Jiefangzhong loquat[J]. South China Fruit Trees, 2004, (06):66-67] spraying indole in the first ten days of March Acid and ammonium molybdate can reduce the acidity of Jiefangzhong loquat to 0.46%-0.60%, but the soluble solids of the fruit are only 9.2%-9.5%. It shows that after the method reduces the total amount of organic acids in the fruit, it als...
