The soilless cultivation base of organic vegetables with water and fertilizer integration is generally located in an area far away from industrial and man-made pollution, which requires flat terrain, convenient transportation, sufficient electricity, and soil, water and air meet the organic certification standards. In densely populated and industrially developed areas. The establishment of organic vegetable base must go through strict site selection and set up obvious isolation belt between it and conventional plots. The isolation belt can be a river or a tree forest belt, and the combination of the two is better. The isolation bandwidth should be greater than 10m.
Protected cultivation of organic vegetables provides quality assurance for the production of organic vegetables and is also beneficial to the quality control of organic vegetables. Main facilities: shed or greenhouse, breeding pond, integrated irrigation system of water and fertilizer, organic nutrient solution preparation center, etc.
The rest.
Before planting organic vegetables, we should make full preparations. Firstly, the closed shed is disinfected at high temperature. In hot summer, most pathogens can be killed by sealing the empty shed so that the temperature in the shed is above 60℃ and sealed for 1 week. Secondly, the substrate is put into the cultivation pot, and the fully decomposed substrate is turned over before use to disperse the fermentation gas, then it can be put into the cultivation pot, and the substrate is slightly lower than the surface of the cultivation pot, and finally the drip irrigation belt is laid.
To carry out soilless culture production, it is necessary to have corresponding equipment and facilities, especially large-scale intensive modernization, which requires more production input. At present, according to China's national conditions, some forms of energy saving and low consumption can be adopted to reduce costs and operating costs.
