Embodiment 1

[0029] A kind of soilless culture method that improves okra zinc content, is characterized in that, comprises the following steps:

[0030] (1) Preparation of soilless cultivation substrate: 50 parts of crop straws were crushed to a length of 1 cm, mixed evenly with 120 parts of animal manure, 60 parts of industrial and agricultural by-products, and 0.3 parts of zinc sulfate to obtain a fermentation base material, which was prepared in After microbial fermentation at 30°C, turn the material once every 12 hours, and stop the fermentation after 250 days to obtain decomposed organic matter. Mix the decomposed organic matter with 600 parts of machine-made sand evenly to obtain a soilless culture substrate rich in zinc;

[0031] (2) Seedling selection: select robust okra seedlings with a height of 6 cm, soak the roots of okra seedlings with 0.5% potassium permanganate solution for 3 minutes, wash them with clean water, and dry them in the air;

[0032] (3) Planting: move the okra s...

Embodiment 2

[0040] A kind of soilless culture method that improves okra zinc content, is characterized in that, comprises the following steps:

[0041] (1) Preparation of soilless cultivation substrate: 30 parts of crop straws were crushed to a length of 2 cm, mixed evenly with 100 parts of animal manure, 80 parts of industrial and agricultural by-products, and 0.1 part of zinc sulfate to obtain a fermentation base material, which was prepared in After microbial fermentation at 35°C, turn the material once every 12 hours, and stop the fermentation after 20 days to obtain decomposed organic matter. Mix the decomposed organic matter with 800 parts of machine-made sand evenly to obtain a soilless culture substrate rich in zinc;

[0042] (2) Seedling selection: select healthy okra seedlings with a height of 6 cm, soak the roots of okra seedlings with 0.6% potassium permanganate solution for 2 minutes, wash them with clean water, and dry them in the air;

[0043] (3) Planting: move the okra se...

Embodiment 3

[0051] A kind of soilless culture method that improves okra zinc content, is characterized in that, comprises the following steps:

[0052] (1) Preparation of soilless culture substrate: 80 parts of crop straws were crushed to a length of 0.5 cm, mixed evenly with 150 parts of animal manure, 50 parts of industrial and agricultural by-products, and 0.5 part of zinc sulfate to obtain a fermentation base material. After microbial fermentation at 28°C, the material was turned every 12 hours, and the fermentation was completed after 30 days to obtain decomposed organic matter. Mix the decomposed organic matter with 500 parts of machine-made sand evenly to obtain a soilless culture substrate rich in zinc;

[0053] (2) Seedling selection: select strong okra seedlings with a height of 10 cm, soak the roots of okra seedlings with 0.3% potassium permanganate solution for 6 minutes, wash them with clean water, and dry them in the air;

[0054] (3) Planting: move the okra seedlings into t...

Abstract

The invention relates to a soilless culture method for increasing the zinc element content in okra. The method comprises the operation steps that a zinc-enriched soilless culture medium is prepared; robust okra seedlings are selected, subjected to root disinfection and then transplanted into customized grooves in a greenhouse; the customized grooves are filled with the zinc element-enriched soilless culture medium; the okra seedlings are subjected to pruning, disease controlling and blossom promoting and fruit retention managing through a conventional method; fruits are picked after being ripen, and then the okra with the high zinc element content is obtained. According to the soilless culture method, the okra is cultured with the zinc element-enriched soilless culture medium, the okra yield and the zinc element content in the fruits can be significantly increased, the economic benefit is good, and the nutrition and health care value of the okra is high; usage of fertilizer and pesticides can be reduced, the cost is low, the product is green and free of pollution, and the method is suitable for large-scale popularization.

Description

technical field [0001] The invention relates to a vegetable soilless cultivation technique, in particular to a soilless cultivation method for increasing the zinc element content of okra. Background technique [0002] my country is facing severe challenges from population growth and land reduction. The population accounts for 1 / 4 of the world's total population, but its arable land area is only 1 / 7 of the world's total arable land area. According to statistics in 2000, the national per capita arable land is only 0.01 hm2, soilless cultivation can provide several times or even more than ten times the quantity of products than ordinary soil cultivation, and can use sandy beaches, saline-alkali and other barren lands to produce agricultural products, laying a solid foundation for the food safety guarantee system. my country is a country with very poor water quality resources, and is listed as one of the 13 water-poor countries in the world. The per capita water resources in the ...
