Abstract

The invention relates to a water nutrient solution cultivation method for vegetables, which comprises the following specific steps: 1, erecting a greenhouse; 2, digging a pit in the greenhouse; 3, after the pit is dug, overspreading a novel pollution-free water proof membrane at the bottom of the pit or at the edge of the pit, erecting a cultivation frame in the pit, and simultaneously laying heating pipes at the bottom of the pit; 4, filling methane waste solution and waste residue in the pit; 5, overspreading vegetables on the cultivation frame; 6, if the temperature is lower than 15 DEG C, starting to heat; and 7, cultivating again according to the step 3. According to the method, the vegetables can grow all the year round without being limited by seasons; the production efficiency is high; the pollution-free organic vegetables have a good mouthfeel and can keep green without any color change no matter how the vegetables are stir-fried, thereby providing a fine appetite for people; detection indicates that fibers of the vegetables cultivated by the method are more than fibers of vegetables cultivated on a green field; the vegetables are beneficial to elimination of toxicant; and meanwhile, the bottom is easy to replace, thereby solving the defect that plants can not be successively planted for 3 years.

Description

technical field [0001] The invention relates to the technical field of agricultural plant cultivation, in particular to a cultivation method of vegetable water nutrient solution. Background technique [0002] The current water nutrient solution is cultivated with hydraulic pools and water nutrient solution. This cultivation method is easy to degrade after years of cultivation and difficult to handle. At the same time, the cost of the water nutrient solution is high, and the competitiveness of the cultivated vegetables is poor. Contents of the invention [0003] The purpose of the present invention is to develop a low-cost, easy-to-change bottom tank, solve the problem of crop rotation, and use different nutrient solutions to achieve high-yield cultivation methods for vegetables. [0004] A kind of cultivation method of vegetable water nutrient solution, its concrete steps are as follows: [0005] ① First set up the greenhouse; [0006] ② Dig a pond in the greenhouse, t...
