Cultivation device with water and soil nutrient maintaining function for tobacco planting

Abstract

The invention discloses a tobacco planting cultivation device with a water and soil nutrient maintaining function, and belongs to the technical field of tobacco planting, the tobacco planting cultivation device comprises a hydroponic box, the inner cavity of the hydroponic box is filled with a cultivation solution, and a plurality of matrix frames are placed in the hydroponic box in a floating mode through the cultivation solution. According to the tobacco seed seedling raising device, large-scale seedling raising treatment on tobacco seeds is achieved through the multiple sets of fixed bases and matrix sleeves, and meanwhile a sealing plate can isolate a cavity in the bottom side of an inner cavity of the floating tank box, so that a cultivation solution can enter according to the cavity volume limited by the sealing plate; the liquid inlet amount of seedling culture liquid in different growth states is adjusted, precise control over culture pressure is facilitated, meanwhile, nutrient supplementation is conducted by evenly dispersing the culture liquid in the water culture box, the absorption amount of the culture liquid is controlled by means of the self-liquid-absorption capacity of a matrix, and the nutrient supplementation efficiency is improved. The problem that the precision is difficult to control when the cultivation liquid is independently added into the matrix sleeve is avoided, and the large-scale cultivation treatment requirement of tobacco seedlings is met.

Description

technical field [0001] The invention belongs to the technical field of tobacco planting, and in particular relates to a cultivation device for tobacco planting with the function of maintaining water and soil nutrients. Background technique [0002] Yunnan, Guizhou, Sichuan and other regions, the main tobacco producing areas in China, have planted a single variety in large areas year after year, resulting in the weakening of tobacco stress resistance, root and stem diseases such as black shank, bacterial wilt, black root rot, underground insect pests, environmental stress damage, etc. The harm is serious. In order to reduce the occurrence of diseases and insect pests and enhance the resistance of tobacco, there are mainly agricultural cultivation measures and breeding new varieties. Tobacco seeds need to be cultivated before planting. [0003] Chinese patent document CN113273484A discloses a hydroponic device and a hydroponic method for a single plant of gene-edited tobacco, ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem of lack of large-scale cultivation ability of tobacco seedlings, and after the nutrient solution is dripped, it is retained and absorbed by the matrix, and cannot be fully absorbed by the root system of the hydroponic device, which affects the maintenance of water and soil nutrients. A cultivating device for tobacco planting with the function of water and soil nutrient conservation
