Sweet pepper hydroponic nutrient solution

Abstract

The invention provides a sweet pepper hydroponic nutrient solution. The sweet pepper hydroponic nutrient solution is prepared from the following components in parts by weight: 300-400 parts of rice-washing water, 1-2 parts of white alum, 5-9 parts of radix aucklandiae, 2-6 parts of sodium molybdate, 3-5 parts of poria cocos, 1-3 parts of fructus amomi rotundus, 1-3 parts of liquorice root, 2-6 parts of calcium nitrate, 1-3 parts of potassium sulfate, 0.5-1.5 parts of ammonium dihydrogen phosphate and 1-2 parts of magnesium sulfate. The rice-washing water being rich in nitrogen, phosphorous, potassium and a plurality of trace elements necessary for the growth of sweet pepper is adopted instead of original rain water or purified water, and the radix aucklandiae, the poria cocos, the fructus amomi rotundus and the liquorice root are added in a cooperation way, so that the sweet pepper can be assisted in absorbing the trace elements fully in a balanced way, the growth and root development of the sweet pepper are facilitated, the resistance of plants is enhanced, the development of physiological diseases is prevented, the nutrients of the sweet pepper hydroponic nutrient solution are much more than nutrients which can be supplied by soil, and the growth of the sweet pepper is facilitated more. Moreover, the phenomenon of rotted root is avoided, and the yield of the hydroponic sweet pepper is increased.

Description

technical field [0001] The invention relates to the field of hydroponic nutrient solutions, in particular to a hydroponic nutrient solution for sweet peppers. Background technique [0002] Now many places carry out soilless cultivation of sweet peppers. In soilless cultivation, artificially prepared nutrient solution is used to supply the needs of plant nutrition. Years of practice have proved that the yield of soilless cultivation is higher than that of soil cultivation, but now artificially prepared The nutrient solution has developed to a bottleneck. The yield and quality of the plants are basically stable, and no major breakthroughs can be made. Researchers need to constantly modify the formula of the nutrient solution to improve and improve the quality of sweet pepper fruits. Moreover, it is necessary to overcome the phenomenon that the existing hydroponic sweet peppers are prone to rotten roots, resulting in reduced yields. Contents of the invention [0003] The pur...
