Nutrient solution for soilless culture of tomatoes

Abstract

The invention discloses a nutrient solution for soilless culture of tomatoes. The nutrient solution comprises the following components in parts by weight: 0.5-2 parts of fructus amomi rotundus, 1-2 parts of liquorice, 200-280 parts of rice washing water, 0.5-2 parts of onion peels, 5-10 parts of fruit kernels and peels and 1-1.5 parts of alum. The nutrient solution for the soilless culture of the tomatoes is prepared from domestic waste such as the rice washing water, the onion peels and the fruit kernels and peels, is rich in various microelements such as nitrogen, phosphorus and potassium required by the growth of the tomatoes and is cooperatively added with fructus amomi rotundus and liquorice, so that the balanced and comprehensive absorption of the microelements by the tomatoes can be promoted, the growth and the root development of the tomatoes can be promoted, and the physiologic diseases can be prevented and controlled; and the nutrients of the nutrient solution far exceeds the nutrients provided by soil, so that the growth of the tomatoes is benefited.

Description

technical field [0001] The invention belongs to the technical field of plant soilless culture nutrient solution, in particular to a tomato soilless culture nutrient solution. Background technique [0002] Soilless cultivation of tomatoes is now carried out in many places. 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 nutrients The liquid has developed to a bottleneck. The yield and quality of plants are basically stable, and no major breakthroughs can be made. Researchers need to constantly modify the formula of the culture liquid to improve and improve the quality of plant fruits. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention discloses a nutrient solution for soilless cultivation of tomato. The content of nitrogen, ph...
