Soilless tomato culture nutrient solution

Abstract

The invention provides a soilless tomato culture nutrient solution, comprising calcium nitrate tetrahydrate, ethylenediaminetetraacetic acid sodium ferric salt, ammonium nitrate, an EM probiotic liquid, potassium nitrate, potassium magnesium phosphate, copper sulfate, manganese sulfate, boric acid, ammonium molybdate, EDTA (Ethylene Diamine Tetraacetic Acid) chelated iron and the balance of water. According to the soilless tomato culture nutrient solution provided by the invention, the EM probiotic liquid is added to propagate strains necessary for probiotics so as to form a good microbial circulation system for the nutrient solution, the system can fully decompose organic matters generated in the nutrient solution in a planting process to transform the organic matters into substances to be absorbed by plants, and the potassium nitrate, potassium magnesium phosphate, copper sulfate, manganese sulfate, boric acid, ammonium molybdate and EDTA chelated iron provide such elements necessary for tomatoes as potassium, magnesium, copper, manganese, boron, molybdenum, iron and the like so as to enable the tomatoes to achieve an optimal growth effect so as to increase the yield and improve the quality.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a tomato soilless cultivation nutrient solution. Background technique [0002] In the process of traditional tomato planting, due to continuous planting, continuous cropping obstacles are particularly large, resulting in many diseases, and a large amount of pesticides have to be sprayed to prevent pests and diseases; in addition, due to the long-term use of chemical fertilizers in traditional tomato planting methods, it is difficult to grow tomatoes. The hardening of the land and the decline in fertility have led to a serious decline in the yield of tomatoes. What is more serious is that the quality of tomatoes is not guaranteed due to the application of a large amount of chemical fertilizers and pesticides. At the same time, the traditional tomato production has the characteristics of cumbersome production management, heavy labor, low production efficiency, high cost and ...

Problems solved by technology

[0002] In the process of traditional tomato planting, due to continuous planting, the barriers to continuous cropping are particularly large, resulting in many diseases, and a large amount of pesticides have to be sprayed to prevent pests and diseases; in addition, due to the long-term use of chemical fertilizers in traditional tomato planting methods, it is difficult to grow tomatoes. The hardening of the land, the decline in fertility and other reasons lead to a serious decline in the yield of tomatoes. What is more serious is that the quality of tomatoes is not guaranteed due to the application of a large amount of chemical fertilizers and pesticides.

At the same time, the traditional tomato production has the characteristics of cumbersome production management, heavy labor, low production efficiency, high cost and poor benefit.

[0003] Soilless cultivation techniques are mostly used now, among which the use of nutrient solution is the most important and most difficult problem. Many soilless cultivation techniques are based on the fact that the composition and content of the nutrient solution are constant. Different elements and their content are required, so this medium is not conducive to the rapid growth and fruiting of tomatoes
