Application of water culture nutrient solution in tomato culture

Abstract

The invention relates to preparation and application of a water culture nutrient solution, in particular to application of the water culture nutrient solution in tomato culture. In combination with different demands of tomatoes in the growth initial stage, flowering fruit setting stage, fruiting stage and other different growth stages for nutrients, nutrient supply to the tomatoes is conducted ina targeted mode. According to the application, the problem is effectively solved that for an existing water culture nutrient solution, nutrient element preparation and supply cannot be conducted for different nutrient demands of crops in different growth stages. The yield of the water culture tomatoes is increased, the content of nitrate in the tomatoes can be effectively lowered, the content of Vc, soluble sugar and soluble solids is increased, the flavor and taste of the tomatoes are obviously improved, and the quality of the tomatoes is improved.

Description

technical field [0001] The invention relates to the preparation and application of a hydroponic nutrient solution, in particular to the application of a hydroponic nutrient solution in cultivating tomatoes. Background technique [0002] As an important part of modern agriculture, facility agriculture is developing rapidly with its incomparable advantages over traditional agriculture, and has become an effective means for farmers in many areas to get rich and increase their income. However, in the production process, the planting structure is relatively simple, the simple pursuit of yield and the excessive use of quick-acting chemical fertilizers, this high-consumption and low-efficiency production method have led to serious problems in facility agriculture. The problems caused by continuous cropping such as secondary salinization of facility soil and soil-borne diseases are becoming more and more serious, which not only reduces the yield and quality of vegetables, but also p...

AI Technical Summary

Problems solved by technology

Soilless cultivation and research in developed countries in Europe have developed rapidly in recent years, while soilless cultivation in my country started relatively late, and the area of ​​soilless cultivation in the 1980s was less than 10hm 2 , but with the development of soilless cultivation technology research, its agricultural production area has also increased rapidly, and by 2005 it had exceeded 1100hm 2 , but due to the high one-time investment of its facilities and equipment, the nutrient solution management requires high technology and other factors, there are many problems in large-scale and intensive production, such as the different water quality in different regions, the difficulty of nutrient solution formulation and configuration, and the lack of soil. Cultivation makes the rhizosphere environment of crops change from soil to water environment or matrix environment. The composition and concentration of nutrient solution must meet the absorption and growth of vegetables, otherwise it will cause unfavorable growth due to unbalanced solution and concentration.

[0009] The above patent literature on tomato nutrient solution is a single formula throughout the growth period, does not provide the best EC value of nutrient solution in different growth periods, and does not mention whether the nutrient solution formula can improve the quality of tomatoes on the basis of high yield
