A kind of full-nutrient soilless culture medium suitable for eggplant and its preparation method and application

Abstract

The invention discloses a total nutrient soilless culture matrix suitable for eggplants and a preparation method and application thereof. The matrix contains an organic culture substrate, an inorganic fertilizer and a water retaining agent; wherein the organic culture substrate comprises 50-75 parts by volume of fermented cassava residue, 0-50 parts by volume of peat and 0-35 parts by volume of vermiculite; the inorganic fertilizer is composed of urea, inorganic phosphate fertilizer and inorganic potash fertilizer, and the urea is absorbed by the water retaining agent, and then is added into the organic culture substrate. By preparation of a vegetable cultivation substrate from the cassava residue as a raw material, the problem of environmental pollution caused by the waste cassava residue can be effectively solved to achieve re-use of resources. The total nutrient soilless culture matrix creatively uses the water retaining agent to absorb the urea and then adds the urea into the organic culture substrate to guarantee slow release of the absorbed N fertilizer (urea) to provide plant growth needs, also decreases N fertilizer loss, improves the utilization rate of the N fertilizer, ensures the scientific use of fertilizers, and reduces environment pollution.

Description

Technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a fully nutritious soilless cultivation substrate suitable for eggplant and its preparation method and application. Background technique [0002] Although the research and promotion of soilless cultivation in my country only emerged in the mid-to-late 1980s, it has developed rapidly. According to incomplete statistics, the area of ​​soilless cultivation nationwide has exceeded 200hm. 2 . The main research and promotion in our country is nutrient solution soilless cultivation, which all uses nutrient solution prepared from chemical fertilizers to irrigate vegetables. The technical requirements for nutrient solution management and root oxygen supply are high and the operation is difficult; and the supporting auxiliary equipment such as cultivation tanks and timers are , water pumps and other input costs are expensive. These factors have seriously hindered t...

AI Technical Summary

Problems solved by technology

[0005] At present, the fertilizers in the existing cultivation substrates on the market cannot meet the needs of the entire growth period of the crops. Therefore, it is necessary to continuously topdress the fertilizer during the cultivation process, or use a more expensive nutrient solution cultivation system to irrigate the vegetable-specific nutrient solution, which costs a lot of money. laborious

The growth process of vegetable crops requires a lot of fertilizers, but if the N fertilizer required by the crops is added to the substrate, it will cause the phenomenon of plant burning
