Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and more specifically, the invention relates to a special soilless culture nutrient solution for Chinese cabbage and a preparation method thereof. Background technique [0002] Soilless cultivation refers to the planting technology that does not use natural soil to cultivate plants, but uses nutrient solutions containing elements necessary for plant growth and development to provide nutrition and enable plants to complete the entire life cycle normally. It has changed the traditional planting habit of agricultural production relying on soil since ancient times, greatly promoted the vigorous development of modern agricultural science and technology, and promoted the transformation of agricultural production to a new stage of industrial production and commercial production, with broad market prospects . [0003] Soilless cultivation replaces the soil environment with the artificially cre...
