Continuous-cropping high-yield cultivation method of okra

Abstract

The invention discloses a continuous-cropping high-yield cultivation method of okra. The method includes: seed coating, seed soaking and germination accelerating, tray seedling breeding, field management, cultivation groove planting, seedling transplanting, integrated water-fertilizer management, pest control and harvesting. The method has the advantages that the picking period of the okra sowed in the same period is prolonged to September even October, fresh fruit yield is increased greatly, and the yield can be increased by 30% according to preliminary calculation; effective physical isolation of root-knot nematode and the young roots of the okra can be achieved at the early growth stage by the aid of special matrix groove cultivation; the use amount of water, fertilizer and chemicals is lowered by the integrated water-fertilizer management system, precise management is achieved, the occurrence of soil-borne diseases such as the root-knot nematode is reduced, energy conservation and emission reduction are achieved, and cost is lowered; the okra is cultivated in cultivation grooves with matrixes in the whole process, the integrated water-fertilizer management system is used, and the method is easy to operate and capable of lowering labor intensity and saving cost.

Description

technical field [0001] The invention belongs to the field of agriculture, in particular to a high-yield cultivation method for continuous cropping of okra. Background technique [0002] Okra, also known as okra and okra, belongs to Malvaceae, and okra is an annual or perennial medicinal and edible herb. Originated in Africa, it is now widely cultivated in tropical and subtropical regions. It was introduced to China in the 1990s and is currently cultivated in most parts of the country. [0003] The traditional cultivation techniques of okra are divided into open-air cultivation and film-covered cultivation. Open-air cultivation has the characteristics of severe weed damage in the early stage, grass and okra compete for fertilizer, etc., and the fertilizer efficiency is low. Manual weeding will significantly increase labor intensity and production costs; film-covered cultivation, It reduces the occurrence of weed damage and maintains the ground temperature and soil moisture, ...

AI Technical Summary

Problems solved by technology

During the planting process of okra, root-knot nematode has become one of the key factors affecting its growth period and yield. Due to the continuous cropping and high temperature and high humidity of okra for many years, soil-borne diseases such as root-knot nematode are particularly serious. Through traditional physical, chemical and Microbial fertilizers and other means to prevent and control it have the characteristics of high technical integration requirements and high production costs, and it is difficult to promote it in large areas in production areas.
