Planting method for stable rotation production of peanut and garlic

Abstract

The invention discloses a planting method for stable rotation production of peanut and garlic; peanut and garlic are subjected to rotation, the garlic is planted conventionally, and the peanut is planted in narrow and wide alternate rows; the wide peanut rows are 50 cm in width, and the narrow peanut rows are 30 cm in width; a midline of each wide peanut row for previous year serves as a midline for a narrow peanut row of next year, and a midline of each narrow peanut row for previous year serves as a midline for a wide peanut row of next year. The planting method for stable rotation production of peanut and garlic according to the invention has the advantages that allicin of the garlic provides good antibacterial and inhibitive effects, allelochemical substances and other factors causingcontinuous cropping obstacles are eliminated, toxin balance due to continuous planting of peanut is broken through, the yield of peanut and garlic is high, and their quality is good.

Description

technical field [0001] The invention relates to a planting method for stable yield of peanuts and garlic in rotation, and belongs to the field of crop cultivation and planting. Background technique [0002] Continuous cropping obstacles will occur when peanuts are planted in successive years. The so-called continuous cropping obstacles refer to the continuous planting of the same or related crops on the same piece of land, even under normal cultivation and management conditions, there will be deterioration of plant growth and development, yield and quality. A large number of studies have shown that the phenomenon of decline, aggravation of diseases and insect pests and other phenomena is the result of the interaction between the two ecosystems of plants and soil. The main reasons can be summarized into three points: one is the autotoxicity of crop root exudates; the other is the deterioration of soil physical and chemical properties and the imbalance of nutrient ratio; the t...

AI Technical Summary

Problems solved by technology

[0003] Peanut continuous cropping obstacles are mainly due to the various pests and diseases remaining on the peanut stumps in the field, and the large increase in pathogenic bacteria and insect sources will aggravate the pests and diseases of peanuts, and during the growth of peanuts, the secretions from its roots and other parts will Inhibit the growth of peanuts, its root exudates cause soil deterioration, nutrient imbalance, aggravation of diseases and insect pests, due to the increased accumulation of toxic substances, hinder the growth of next crop peanuts

The growth of peanuts has a certain selectivity for the absorption of nutrients in the soil, and the absorption of phosphorus, potassium, boron, and molybdenum is relatively large. The lack of individual elements will be aggravated by successive planting. Therefore, repeated planting of peanuts will cause a large reduction in peanut production. The above factors have been restricting the increase of peanut area and the development of peanut planting industry
