Abstract

The invention relates to a special nutritional meal for soilless culture tomatoes and preparation and applications of the special nutritional meal. The special nutritional meal consists of a nutritional matrix and a nutritional fertilizer in mass ratio of (98.5-99.5):(0.5-1.5), wherein the nutritional fertilizer is divided into a nutritional fertilizer A and a nutritional fertilizer B, and the mass ratio of the nutritional fertilizer A to the nutritional fertilizer B is (0.1-0.3):(0.4-0.7); the nutritional matrix is prepared from the following raw materials: ginger plants, oil dregs, scarps, sawdust and microorganism bacterium agents by adopting step-by-step fermentation and adding calcium magnesium phosphate fertilizer, calcium nitrate and vermiculite; the raw materials of the nutritional fertilizer A and the nutritional fertilizer B are urea and potassium sulfate respectively; and the nutritional matrix, the nutritional fertilizer A and the nutritional fertilizer B are respectively and independently packaged. According to the special nutritional meal for the soilless culture tomatoes, the matrix is good in physical behavior, contains phosphorus nutrition and calcium nutrition which are not easy to run off. Nutrients in the matrix and the nutrients of the nutritional fertilizers interact, therefore, the effect of balancing the nutrients of the tomatoes at different growth stages is jointly achieved.

Description

technical field [0001] The invention relates to a special nutritional package for soilless cultivation tomatoes prepared by utilizing industrial and agricultural production organic wastes and inorganic fertilizers, a preparation method and application thereof, and belongs to the technical field of soilless cultivation and resource utilization. Background technique [0002] Soilless cultivation is an advanced technology widely used in facility agriculture in the world. It has many advantages such as avoiding soil-borne diseases and insect pests and continuous cropping obstacles, high fertilizer utilization rate, water saving and production controllability. It has become a reliable method for the development of pollution-free green food production. way. Although compared with the Netherlands, Japan, the United States and other countries, the research and application of crop soilless cultivation technology in my country started relatively late, but the rapid development speed i...
