Embodiment 1

[0138] The 500 mu Majia pomelo orchard planted by Jiangxi Dongli Pomelo Industry Technology Co., Ltd. in 2009 was planted by the method described in the present invention from 2016 to 2017. After investigation, before adopting the method of the present invention, the Majia pomelo output in this orchard is 1050kg / mu, and the commercial fruit rate (correct fruit shape) is 60%, and the fruit soluble solid content is 8.9%, and titratable acid is 0.72% .

[0139] A. In the winter of 2016, the pH value of the soil in the Majia pomelo orchard was determined to be 4.8, and the base fertilizer was prepared according to 600kg / mu of decomposed organic fertilizer, 30kg / mu of dolomite powder and 30kg / mu of calcium magnesium phosphate fertilizer. After mixing, it was buried and applied to the soil 10cm deep. After March 2017, lime was sprinkled around the tree tray according to 30kg / mu, and the pH of the soil was adjusted to 5.6.

Embodiment 2

[0164] The 300 mu Majia pomelo orchard planted by Jiangxi Lvfeng Forestry Co., Ltd. in 2009 was planted using the method described in the present invention from 2016 to 2017. After investigation, before adopting the method of the present invention, the Majia pomelo output in this orchard is 1120kg / mu, the commercial fruit rate (correct fruit shape) is 62%, the fruit soluble solid content is 8.5%, and the titratable acid is 0.75%. .

[0165] A. In the winter of 2016, the pH value of the soil in the Majia pomelo orchard was determined to be 4.6, and the base fertilizer was prepared according to 650kg / mu of decomposed organic fertilizer, 35kg / mu of dolomite powder and 35kg / mu of calcium magnesium phosphate fertilizer. After mixing, bury it and apply it to the soil 10cm deep. After March 2017, lime was sprinkled around the tree tray according to 35kg / mu, that is, the pH of the soil was brought to 5.5.

Abstract

The invention relates to the field of plant planting, and provides a method for reducing the malformation rate of citrus fruits. The method comprises the steps that the pH value soil is adjusted to range from 5.5 to 6.5, the boron content of the soil of trees is increased, the tree structure is transformed, flower thinning is carried out in the flower season, tree nutrition is supplemented, the flower bud quality is improved, and therefore misshapen fruitlets are reduced; flower thinning is carried out in the second physiological fruit drop period to reduce nutrient consumption, a fruit retention agent is sprayed to control physiological fruit drop, and the fruit upright degree is improved; overground part nutrition and accumulation of carbohydrate are increased, flower bud differentiationis promoted, and the fruit quality is improved. According to the method, the malformed fruit occurrence rate can be reduced to be below 10%, the commodity fruit rate (85% or above) is remarkably increased, the yield of the citrus fruits can be increased by one time or above, and the fruit quality is obviously improved.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a method for reducing the deformity rate of citrus fruits. Background technique [0002] Citrus is a general term for tangerine, tangerine, orange, kumquat, pomelo and trifoliate. It is one of the important fruits in the world and ranks among the best in economic crops. China is the main birthplace of citrus in the world and the country with the earliest history of cultivating citrus in the world. [0003] Fruit deformity refers to the abnormal development of a certain part of the fruit, resulting in a hyperplasia shape that is different from the normal shape. Fruit deformity is one of the factors affecting the quality of citrus. Field surveys found that during the second physiological fruit shedding period, the proportion of young fruit deformities of citrus such as Majia pomelo hanging on fruit trees is very large, reaching about 60% of all young fruits; After the end of the sec...
