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, ...

Examples

Embodiment 1

[0038] (1) Seed coating: In view of the serious characteristics of soil-borne diseases such as root-knot nematodes in okra, select okra seeds that have been coated to reduce the carrying of pathogenic bacteria and reserve them;

[0039] (2) Seed soaking to accelerate germination: Soak the okra seeds coated in step (1) in 25°C water for 12 hours, take them out and place them on a tray, cover the bottom of the tray with wet gauze, put the tray in an incubator at 30°C for germination, The next day, see that the seeds spit out white, ready to sow;

[0040] (3) Seedling cultivation in plug trays: The size of the plug tray is 72 holes, and the peat soil, coconut peat, vermiculite and perlite are evenly mixed according to the mass ratio of 5:4:0.5:0.5, soaked in water, and placed in a tray, and then step (2) As for the good germinated okra seeds in the hole, place 2 seeds in each hole, and place the sown hole plate in the greenhouse or small shed according to the temperature and temp...
