Greenhouse cultivation system

Greenhouse cultivation is divided into soil cultivation and soilless cultivation. Soilless cultivation refers to the cultivation method in which water, grass charcoal, forest mulch, vermiculite and other media are used as the substrate for the root system of the plant to fix the plant, and the root system of the plant can directly contact the nutrient solution . The nutrient solution composition in soilless culture is easy to control and can be adjusted at any time. In places where there is no soil, such as deserts, beaches, and deserted islands, where the light and temperature are suitable, it can be carried out as long as there is a certain amount of fresh water supply. Soilless culture can be divided into hydroponic culture, fog (air) culture and substrate culture according to the different culture media.

Cultivation method
Hydroponics
Deep flow cultivation Deep liquid flow technology, the nutrient solution in the planting tank is 5-10 cm thick, and the nutrient solution must flow to supplement the oxygen in the nutrient solution and make the nutrient solution more uniform. The late-night flowing water accompanies the facility by the planting tank, planting net or fixed value Plate, liquid storage tank, circulation system and other parts
	Shallow flow cultivation Shallow liquid flow (NFT): The depth of the nutrient solution is only a few millimeters. The liquid flow flows through the vegetable roots in a film-like manner. Part of the vegetable roots is immersed in the shallow flowing nutrient solution, and the other part is exposed to the moisture in the planting tank. It can better solve the oxygen demand of root respiration. The planting trough must have a certain slope (around 1:75).
Air culture In aerosol cultivation, vegetables are hung in a cultivation device, such as a trough, box or bed, and the roots of the vegetables are exposed inside the cultivation device. The spray device atomizes the nutrient solution into small droplets and sprays them directly on the surface of the plant roots. according to different facilities, it can be divided into "A"-shaped spray culture, trapezoidal spray culture, mobile spray culture, column equation spray culture, etc.
Substrate cultivation
	Coconut peat substrate cultivation Coconut peat substrate cultivation is characterized by water retention, air permeability, EC and PH value suitable for the growth of a variety of plants, has high fiber, has good elasticity, can be transported after compression in a large proportion, saving transportation costs
Rock wool substrate cultivation Rock wool is a cultivation technique in which plants are planted in pre-made rock wool. Rock wool is made of 60% diabase, 20% limestone and 20% coke, melted at a high temperature of 1600℃, sprayed into 0.005mm fibers, and pressed into blocks to make their weight 77~80kg/m3 The resulting inorganic solid matrix.
