Abstract

The invention discloses a nutrient solution for soiless tomato cultivation. The nutrient solution comprises the following raw materials: ammonium sulfate, potassium nitrite, calcium nitrate, magnesium sulfate, potassium dihydrogen phosphate, potassium, superphosphate,disodium edetate, ferrous sulfate, boric acid, manganese sulfate, copper sulfate, zinc sulfate and ammonium molybdate. Above raw materials are made into solution A, solution B and solution C. The nutrient solution is reasonable in structure and rich in nutrition, so that nutrition needed by tomatoes in each period can be satisfied. Meanwhile, self resistance can be reinforced, the incidence of pests and diseases is reduced, the using amount of pesticides is reduced, and the yield and quality of vegetables are improved. In addition, the use of chemical fertilizers is reduced, the labor cost is reduced, and the operation is simple, so that the economic benefits are effectively improved.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a nutrient solution for soilless cultivation of tomatoes. Background technique [0002] In recent years, my country's soilless cultivation technology has developed rapidly. In soilless culture, crops rely entirely on nutrient solution to provide the nutrients and water needed for crop growth. Whether each nutrient and nutrient element meets the requirements of different growth stages during the growth of crops depends on the formula and concentration of the nutrient solution. [0003] Soilless cultivation refers to the method of cultivating crops with nutrient solution or solid substrate plus nutrient solution without soil. It has changed the planting habit of agricultural production that has relied on soil since ancient times, and pushed agricultural production to a new stage of industrial production and commercial production. . Its core is not to use natural soi...
