Soilless cultivation method of organic leguminous vegetables

Abstract

The invention relates to a soilless cultivation method of organic leguminous vegetables. The method comprises the preparation steps of a substrate special for production of the organic leguminous vegetables, and the steps are that industrial and agricultural organic waste and livestock excrement or plant cake residues are mixed according to the proportion of 5-8: 2-5 for aerobic fermentation, a substrate A is obtained, the substrate A is detected, and the total nitrogen nutrient amount, the total phosphorus nutrient amount and the total potassium nutrient amount are adjusted through organic fertilizer or mineral phosphorus potassium fertilizer according to the technical parameters of the substrate special for production of the leguminous vegetables; the PH value of the substrate is adjusted through sulfur or quicklime powder; the unit weight and the porosity of the substrate are adjusted through river sand, slag and the like; the EC value and the CEC value are adjusted through turf or vermiculite or the like; the requirements for the technical parameters of the substrate special for production of the leguminous vegetables are met, the soilless cultivation method of the organic leguminous vegetables completely eliminates the dependence of the soilless cultivation technology on the inorganic synthetic fertilizer, and gives full play to the function of nodule bacteria, products meet the standards of organic agricultural products, cost is low, yield is high, and benefits are high.

Description

technical field [0001] The invention relates to a soilless cultivation method for organic vegetables, in particular to a soilless cultivation method for organic bean vegetables. Background technique [0002] Beans and vegetables (kidney beans, cowpeas, broad beans, edamame, etc.) are highly nutritious foods widely loved by people, and organic legumes and vegetables are even more expensive and hard to find. However, the current organic agricultural products are all produced on the soil using organic fertilizers. Organic fertilizers have limited nutrients, large irrigation and soil losses, low production capacity, and high unit product costs. Moreover, the transformation of organic facility agriculture is very difficult now, with long conversion cycles, serious soil-borne diseases, limited prevention and control methods, and high risks in production and operation. The current soilless cultivation technology (whether liquid or solid) has not completely got rid of the dependenc...

Problems solved by technology

However, due to some characteristics of legume vegetables and rhizobia, the role of rhizobia has not been brought into play in the current production.

At the same time, a large amount of industrial and agricultural organic wastes have not been effectively utilized, some have been used as fuel, and some have been landfilled, resulting in a great waste of resources and environmental pollution
