Cultivation method of preventing banana continuous cropping obstacle in banana-rice-pineapple crop rotation

Abstract

The invention discloses a cultivation method of preventing banana continuous cropping obstacle in banana-rice-pineapple crop rotation, which comprises that a banana plantation with serious banana continuous cropping obstacle is cleaned away; base fertilizer is put into the banana plantation; water is irrigated into the banana plantation and the plantation is harrowed; on July of the first year, rice is began to be planted; after the rice is harvested, water is drained and the field is dried; the soil is plowed and base fertilizer is put into the field; on January of the second year, pineapple is planted; after the pineapple is harvested, the soil is plowed; planting holes are dug and base fertilizer is put into the planting holes; and on July of the third year, banana is planted again. By circulating this cropping rotation method for 1 to 2 weeks, the banana continuous obstacle can be prevented effectively; the micro-ecological environment of banana plant roots is improved; the banana is promoted to grow; the use of farm chemical is reduced; the production cost of the banana is reduced and the use rate of farmland is increased; and the economic benefit is increased.

Description

technical field [0001] The invention belongs to the high-tech field of agricultural intensive production, and in particular relates to a cultivation method for preventing and controlling banana continuous cropping obstacles by crop rotation of banana-rice-pineapple, that is, improving the rhizosphere soil ecological environment of banana plants through crop rotation to prevent and control banana continuous cropping obstacles, and then repairing Cultivation methods for improving continuous cropping soil. It is used to solve the problem of banana growth obstacles caused by the aggravation of soil-borne diseases and insect pests and the deterioration of soil physical and chemical properties caused by continuous cropping for many years. Background technique [0002] The banana industry is an important pillar industry of my country's tropical agriculture. In recent years, due to the reduction of arable land, the drive of economic interests, and the influence of production condit...

AI Technical Summary

Problems solved by technology

In recent years, due to the reduction of arable land, the drive of economic interests, and the influence of production conditions, the banana planting mode is mainly based on large-scale continuous cropping. With the increase of continuous cropping years, continuous cropping obstacles are likely to occur, mainly manifested as Deterioration of soil ecological environment, deterioration of physical and chemical properties, acidification and compaction, imbalance of microbial flora, aggravation of soil-borne diseases and insect pests, etc., coupled with autotoxicity caused by root exudates, etc. lead to weakened growth of bananas, reduced disease resistance, and reduced yield and quality. will cause miscarriage
