Abstract

The invention discloses a leafy vegetable soilless culture nutrient solution which is prepared from the following raw materials, by weight: 20-40 parts of magnesium sulfate, 10-30 parts of potassium dihydrogen phosphate, 50-70 parts of potassium nitrate, 30-50 parts of calcium nitrate, 2-5 parts of iron humate, 20-40 parts of ammonium bicarbonate, 30-50 parts of urea, 20-40 parts of chitosan nano powder, 0.2-1 part of trace elements and 100-300 parts of water. With the nutrient solution, leafy vegetable iron content, yield and quality can be improved. The nutrient solution is suitable for most leafy vegetables, and is suitable for large-scale and systematic soilless culture.

Description

technical field [0001] The invention relates to the field of soilless cultivation, in particular to a nutrient solution for soilless cultivation of leafy vegetables. Background technique [0002] In daily life, leafy vegetables have many varieties and rich nutrition, and are deeply loved by consumers. Therefore, leafy vegetables have a large amount of cultivation, occupy a lot of farmland, consume more manpower and material resources, and develop leafy vegetables Soilless cultivation technology is an inevitable trend. Soilless cultivation of vegetables refers to the cultivation method of watering vegetables with nutrient solution without using natural soil, or directly planting vegetables in nutrient solution, also known as nutrient solution cultivation, which is a high-tech agricultural technology. Compared with soil cultivation, soilless cultivation of vegetables absorbs nutrients more efficiently, overcomes the harm of diseases and insect pests caused by continuous cropp...
