Method for controlling fruit cracking of pomelo through sequential management

Abstract

The invention discloses a method for controlling fruit cracking of pomelo through sequential management. According to the invention, nutrient elements and pesticides are timely applied according to physiological cycle and pest occurrence characteristics of the pomelo in a year, so fruit cracking and pest occurrence of the pomelo are reduced, wherein the physiological cycle of the pomelo in a year successively comprises a spring shoot period, a flowering period, a physiological fruit drop period, a young fruit period, a fruit harvest period and a postharvest reconditioning period. The method comprises the following steps: S1, before the spring shoot period, i.e., during the postharvest reconditioning period, applying a base fertilizer and trace elements; S2, during the spring shoot period, diluting the fertilizer with water by 600 to 800 times, carrying out foliage spraying for 3 to 6 times; and S3, diluting the fertilizer by 800 to 1000 times, and spraying 100 to 200 kg per mu of the diluted fertilizer onto the root part of a fruit tree during the spring shoot period. The method provided by the invention can efficiently prevent and control biting pests from occurrence in a pomelo orchard, controls the fruit cracking rate of the pomelo to be 5% or less at the same time, has the advantages of simplicity, practicability, significant pest-control and cracking-control effects, etc., and is applicable to popularization.

Description

technical field [0001] The invention relates to the technical field of citrus cultivation, in particular to a method for timing management and control of pomelo fruit cracking. Background technique [0002] Pomelo is a citrus plant of Rutaceae, and Wendan pomelo is a famous fruit of pomelo. my country's Wendan pomelo, Shatian pomelo, Pingshan pomelo and Thailand's Siam pomelo are known as the world's four famous pomelo.
