Planting method for controlling pimento epidemic diseases by interplanting field of pimento with garlic

Abstract

The invention relates to a planting method for controlling pimento epidemic diseases by interplanting the field of pimento with garlic. The method includes the steps that ridging is conducted, the pimento is planted in a twin-row mode, the garlic is generally planted, three rows of garlic are planted every 6-10 rows of pimento in a pimento variety field in a mixed mode, and it is required that the pimento variety is about 10 cm higher than the garlic variety; the line spacing of the pimento is 40 cm, the planting distance of the pimento is 40 cm, the garlic is interplanted in field ditches, the line spacing of the garlic is 15 cm, and the planting distance of the garlic is 8 cm; the line spacing of the pimento and the garlic is 15 cm; pesticide liquid with the concentration being 250 mg / L is prepared through 50% dimethomorph wettable powder and warm water at the temperature of 55 DEG C before seedling cultivation, selected pimento seeds are steeped in the pesticide liquid, steeping and stirring are performed at the same time, and the seeds are fished out and dried after 20 minutes for seedling cultivation. According to the technology, by interplanting the field of pimento with garlic, the garlic can secrete allicin in the growing process, and the allicin accumulated in soil can deform pathogenic bacterium mycelia of the pimento epidemic diseases, deform spore germ tubes and reduce the spore germination quantity.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a planting method for interplanting sweet pepper with garlic to control sweet pepper blight. Background technique [0002] Sweet pepper blight is a soil-borne disease caused by Phytophthora capsici; it causes yield reduction or even crop failure, and becomes a devastating disease of sweet pepper worldwide. Phytophthora capsici (P. capsici) is a typical soil and water-borne disease, mainly transmitted by soil. Pathogens survive in the soil in a dormant or saprophytic state. After overwintering, the pathogenic bacteria spread through rain splash or irrigation water and infect the base of sweet pepper stems. After infection, the cortex of the lesion rots and gradually withers and dies. Heavy cropping, poor drainage, excessive density, and weakened plants can easily cause the disease to occur in large areas. [0003] At present, large-scale single continuous cropping is used in swe...
