Continuous cropping planting method for not reducing output of spring vigna unguiculata

Abstract

The invention discloses a continuous cropping planting method for not reducing the output of spring vigna unguiculata. The method comprises the following steps that in late winter, fertilization and deep tillage are carried out on a planting land, in early spring, a base fertilizer is applied, land preparation is carried out, vigna unguiculata seeds are directly sown, film covering is carried out,the line roads of plants are determined, after vigna unguiculata sprouts and comes up out of the ground, trepanning is carried out on thin film, vigna unguiculata seedlings grow on put-up shelves, and the occurrence of pest and disease damage is prevented. The continuous cropping planting method for not reducing the output of spring vigna unguiculata has the advantages that the method is simple and practical, is suitable for continuous cropping vigna unguiculata planting lands of soil hardening and improves acid soil, decomposed animal dung is adopted to make soil foam and mature, in winter,deep tillage is carried out, a methane fluid is applied, pest and disease damage bacteria source and ova can be killed, a maruca testulalis geyer prevention drug of vigna unguiculata has a smooth saturation curve after adopting modification, the drug properties can last for 5-7 days, and the drug residues are little.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a continuous cropping planting method of spring cowpea without reducing production. Background technique [0002] Cowpea is commonly known as carob, ginger bean, belt bean, and hanging bean. Cowpea is divided into long cowpea and short cowpea, belonging to the leguminous plant. Vigna is an annual plant of the leguminous family. There are three kinds of stems: dwarf, semi-climbing and trailing. Cultivation in the south is dominated by vines, followed by dwarfism. Annual twining herbaceous plant of Papilionaceae, leaflet 3, terminal leaflet diamond-shaped ovate, 5-13 cm long, 4-7 cm wide, apex acute, base nearly round or broadly cuneate, glabrous on both sides, lateral Leaflets obliquely ovate; stipules ovate, about 1 cm long, extending downward into a short distance at insertion. Calyx campanulate, glabrous; corolla lavender, about 2 cm long, with li...

Problems solved by technology

[0003] Cowpea avoids continuous cropping and heavy cropping, resulting in reduced production, because cowpea absorbs more nitrogen fertilizers in the early growth stage, phosphorus and potassium fertilizers in the middle and late stages of growth, and a large amount of micro-fertilizers (such as zinc fertilizers, calcium fertilizers, etc.), resulting in an imbalance of soil nutrients in the planting ground. Because the root system of cowpea is well-developed, organic acid in the soil is caused to secrete too much, and root system disease occurs, so the present invention separates a kind of continuous cropping planting method of spring cowpea without reducing production
