Pest controlling method for Malus halliana

Abstract

The invention discloses a pest controlling method for Malus halliana. According to the technical scheme, the used medicament is X times liquid; when the Malus halliana is in the environment with the temperature below Y DEG C, the medicament which is sprayed on branches and leaves of the Malus halliana is (X-2X) times liquid; when the Malus halliana is in the environment with the temperature above Y DEG C, the medicament which is sprayed on branches and leaves of the Malus halliana is (2X-3X) times liquid. The pest controlling method is capable of solving the problem that influenced by temperature, the traditional pest controlling method for the Malus halliana causes damage to normal growth of the Malus halliana.

Description

technical field [0001] The present invention relates to a kind of cultivation method for the crater crabapple, more specifically, it relates to a pest control method for the crater crabapple. Background technique [0002] Suisi crabapple is a plant of the genus Malus in the Rosaceae family, and it is a unique plant in China. Distributed in Sichuan, Anhui, Shaanxi, Jiangsu, Zhejiang, Yunnan and other places in mainland China, it grows in areas with an altitude of 50 meters to 1,200 meters, and mostly grows in jungles and mountain streams on raw hillsides. It has been artificially introduced and cultivated. Small deciduous tree with open branches, ovate leaves, 5-7 flowers clustered on the branches, bright red, open from April to May. Up to 8 meters high. The branches are steep and the crown is broad and oval. Bark taupe, smooth. Young branches brown, sparsely pubescent, later turning reddish brown. Alternate leaves, elliptic to long elliptic, slightly acuminate at the ap...

Problems solved by technology

However, the existing insecticidal methods basically remain unchanged. Generally, the X-times liquid of the drug is prepared according to the ratio disclosed in the drug instructions, but the X-times liquid configured according to this ratio can be used. It has the effect of killing insects, but this kind of ratio to configure the X-fold liquid of the drug is not conducive to the normal growth of the crabapple

The reason is that, affected by the temperature, the drug will affect the chlorophyll of the Begonia chinensis. At generally lower temperatures, the photosynthesis of chlorophyll is weak, so the damage of the drug to chlorophyll is less, and when the temperature is higher, The photosynthesis of chlorophyll is strong, so the drugs with the same concentration ratio will greatly damage the chlorophyll, which will damage the chlorophyll of the crabapple, affect the normal photosynthesis of the crabapple, and then affect the normal growth of the crabapple
