Vegetable shelters include greenhouses and greenhouses. Because the environmental conditions and planting methods in protected areas are different from those in open fields, the fertilization techniques are different from those in open soil.
(1) Due to the high use efficiency of soil in protected areas, vegetables take away a lot of nutrients from the soil each year. Therefore, the amount of fertilizer should be increased, and the various nutrients that have been taken away from the crop should be reasonably returned.
(2) When fertilizing, it is necessary to prevent uncoordinated soil nutrients, soil salt accumulation, soil acidity and alkalinity disorders caused by unreasonable fertilization, and to use as little fertilizer as possible.
(3) Combining cultivation measures to effectively determine the application method of fertilizers, minimize the accumulation and loss of fertilizers in the soil, and increase the utilization of fertilizers.
(4) Pay attention to balanced fertilization, place NPK and various trace element fertilizers in the same important position, enhance the immunity of crops, and reduce the occurrence of pests and diseases.

Companies registered capital of 35 million yuan, the end of 2014 the total assets of 48.69 million yuan, including fixed assets of 37.52 million yuan. The company's existing cooperation Orange cultivation base 7043.5 acres, the company production base is located in Jiangxi County Tech Industrial Park Chu Tan industrial area, covers an area of 120 acres, it has built a standard plant 9,000 square meters, Nissan 6000 kg Orange enzymes and other liquid enzyme products. Enzyme, known as enzyme, refers to a polymer substance having biocatalytic functionality. In the catalytic reaction system an enzyme, the reactant molecules are known as substrates, enzyme substrates by catalytic conversion to another molecule. Almost all cellular activity of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts, enzymes chemical reactions by lowering the activation energy to accelerate the rate of the reaction, most of the enzyme catalyzed reaction rate can be increased a million times; in fact, the enzyme is to provide an activation energy needs than another low way, so that more particles to have less than the activation energy of the reaction kinetic energy, thus speeding up the reaction rate. Enzyme as a catalyst, in itself is not consumed during the reaction, it does not affect the chemical equilibrium reactions. Positive enzyme catalysis, but also a negative catalytic effect, not only to accelerate the reaction rate, but also to reduce the reaction rate. And other non-living catalysts is different, having a high degree of specificity of enzyme, only a catalytic reaction or produce a particular specific configuration.
