Plant nutrient solution for soilless culture of tomato

Abstract

The invention provides a plant nutrient solution for soilless culture of tomato. The plant nutrient solution is prepared by the following raw materials in part by weight: 2 to 4 parts of potassium nitrate, 3 to 8 parts of calcium nitrate, 1 to 5 parts of magnesium sulfate, 1 to 3 parts of potassium phosphate, 1 to 2 parts of potassium sulphate, 1 to 2 parts of monopotassium phosphate, 0.1 to 0.15 part of Na2-EDTA, 0.05 to 0.1 part of Fe-EDTA, 0.01 to 0.05 part of molybdic acid, 0.01 to 0.03 part of manganese sulfate, 0.3 to 0.5 part of sodium tetraborate, 2 to 4 parts of superphosphate, 0.003 to 0.01 part of zinc sulfate, 0.001 to 0.002 part of copper sulfate, 0.001 to 0.003 part of ammonium nitrate, 1 to 3 parts of urea, 1 to 2 parts of organic acid, 0.5 to 1 part of beta cyclodextrin, 0.05 to 0.1 part of vitamin B, 2 to 4 parts of chitosan, 1 to 2 parts of nicotinamide, 0.5 to 2 parts of amino acid, 0.3 to 0.5 part of diethyl aminoethyl hexanoate, 0.02 to 0.5 part of gibberellin, and 5,000 to 7,000 parts of water. According to experiment, the plant nutrient solution provided by the invention can be used for carrying out soilless culture of tomato, and the tomato has high plant height, thick stem, high cluster and high output.

Description

technical field [0001] The invention provides a plant nutrient solution, in particular to a plant nutrient solution for tomato soilless cultivation. Background technique [0002] Soilless culture refers to the method of cultivating crops with nutrient solution or solid substrate plus nutrient solution without soil. It has changed the planting habit that agricultural production has relied on soil since ancient times, and pushed agricultural production to a new stage of industrialized production and commercial production. Its core is not to use natural soil. Plants are produced in cultivation devices filled with nutrient solutions or grown in solid substrates containing organic fertilizers or filled with nutrient solutions. This artificially created plant root environment can not only meet the needs of plants for mineral nutrition. , moisture and air conditions, and can be artificially controlled and adjusted. The composition of nutrient solution in soilless culture is easy ...

AI Technical Summary

Problems solved by technology

The concentration of nutrient solution, the amount of liquid supply, the amount of oxygen supply, and the temperature all need to be precisely controlled. In addition, soilless cultivation should pay special attention to the adjustment of the pH of the nutrient solution, which often causes various physiological obstacles due to improper pH.
