Ecological cultivation method for preventing and controlling pepper phytophthora blight and improving quality and efficiency by utilizing dandelion planting

Abstract

The invention discloses an ecological cultivation method for preventing and controlling pepper phytophthora blight and improving quality and efficiency by utilizing dandelion planting, and belongs to the technical field of crop planting. The method comprises the steps that the application amount of organic fertilizer in base fertilizer before pepper field planting is increased by 10-30% compared with the conventional application amount; pepper is planted in high ridges, two rows are arranged on the ridges, and field planting is conducted according to conventional density; an under-film drip irrigation mode is adopted for watering, and black films are used for mulching; after field planting of the pepper, dandelion is planted among the pepper in each hole of the pepper rows; according to the growth of the dandelion and the growth state of the pepper, lateral branches and leaves below first pepper are removed; and the dandelion is harvested for multiple times, namely, the dandelion is harvested every time the leaves grow to 15-25 cm. Through reasonable planting of the dandelion, the occurrence of pepper phytophthora blight of the main crop pepper is effectively prevented and controlled, the yield of the main crop pepper is increased, the quality of the pepper is improved, the land utilization rate is increased, and the purpose of ecological and efficient planting of the pepper is achieved.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to an ecological cultivation method using dandelion planting to prevent and control pepper blight and increase quality and efficiency. Background technique [0002] Pepper blight is the most common disease in pepper production. Once it occurs, it can reduce the production of pepper by more than half, or even stop production. Pepper blight is a soil-borne disease, which is mainly spread in the soil, and can also be widely spread through the air, watering, wind and rain, and diseased plant residues. It has the characteristics of fast transmission speed, strong transmission ability, and difficult control. At present, chemical pesticides are mostly used for prevention and control in production, but this method of prevention and control has problems such as pesticide residues and environmental pollution, and it is also easy to produce drug resistance, and its control effect is not ...

Problems solved by technology

At present, chemical pesticides are mostly used for prevention and control in production, but this method of prevention and control has problems such as pesticide residues and environmental pollution, and it is also easy to produce drug resistance, and its control effect is not obvious

Disease control is mainly based on prevention and supplemented by treatment. Although leeks or other crops (such as perilla) and peppers are intercropped to prevent and control pepper blight in production, because leeks or other crops and peppers are planted alternately or in separate rows, each Occupying their own space will lead to a reduction in the planting area of ​​pepper or the number of pepper planting plants. Therefore, although this method can effectively prevent and control the pepper disease, it will greatly reduce the yield of the main crop pepper.
