A kind of apple planting disease prevention method

Abstract

The invention discloses an apple planting and disease prevention method. The method comprises the steps that the whole orchard is subjected to deep tillage in early November; a organic fertilizer and a micro-element fertilizer are increased, orchard irrigation starts to be conducted in early March and in early June, and orchard inter-row planting of green manure plants is conducted in early May; flower thinning is conducted in the flowering phase, central flower is reserved, ray flower is thinned and removed, a high-calcium liquid fertilizer is sprayed on full trees 10-15 days after flower dropping, summer pruning starts to be conducted in late June, and fruits are stored at low temperature after being harvested; in the dormancy stage of the apple trees, for the trees infected by iron-deficiency yellows, instillation is conducted by hanging bags on the trees to control the iron-deficiency yellows. By means of the method, the rate of the diseased fruit caused by apple bitter pit and pit spot and the rate of diseased plants infected by apple yellows are greatly reduced, and the yield, quality and output value of apples are improved by a large margin.

Description

technical field [0001] The invention belongs to the technical field of apple insect pest prevention, and relates to an apple planting disease prevention method. Background technique [0002] With the continuous expansion of apple area, the extension of tree age, the reduction and lack of soil trace elements, the destruction of soil structure by long-term application of chemical fertilizers in orchards, the emergence of a large number of double-cropped orchards, climate change, changes in cultivation methods and other factors, the types and hazards of apple diseases and insect pests There have been new changes in the degree, and the occurrence of apple physiological diseases is becoming more and more serious. [0003] According to the survey, the physiological diseases currently occurring in production mainly include yellowing disease, small leaf disease, bitter pit disease, pox spot disease, boiled disease, fruit cracking disease, sunburn, etc. According to preliminary stati...
