Pneumatic Telescopic Mast
Pneumatic telescopic mast with power of air source, promote the movement of multicylinder through air compression to lift the mast. Pneumatic telescopic mast industry has experienced a rapid development recently. This mast has been widely used in various fields such as illumination, communication, disaster relief and etc. Due to the features of light loading, general structures, normal maintenance, high security, extreme weather, pneumatic masts have been recognized gradually.

The use of biological fertilizer is one of the most feasible and effective methods for solving pesticide residues. It has good fertilizer efficiency and can reduce harmful residues such as nitrates and heavy metals caused by the large-scale use of chemical fertilizers in agricultural products. And killing pathogens and pests, and thoroughly disinfecting the soil, eliminating a route for the spread of pathogenic bacteria, is the best measure for the production of pollution-free agricultural products. Only by eliminating the pathogens in the soil environment well can we fundamentally reduce pests and diseases, use less pesticides or no pesticides, and completely eliminate pesticide residues.
In addition, biological fertilizers, especially bio-organic fertilizers, are efficient, long-lasting, non-polluting, and have no harmful effects on humans, livestock, and crops; second, they improve soils, promote the formation of aggregate structures, and have good effects on the transformation of desertified land and saline-alkali land; The third is to save energy and maintain the environment.
Bio-fertilizer can eliminate vegetable "drugs"
At present, the problem of pesticide residues in vegetables is more serious. The main reasons are: First, the application of a large number of chemical fertilizers, causing harmful substances such as nitrates and heavy metals in vegetables, causing soil compaction and browning of soil and causing serious pests and diseases; secondly, the continuous application of pesticides causes serious soils. Pesticide residues and the resistance of pathogens are also strengthened. The pathogens in the soil are accumulating more and more, causing widespread pests and diseases. Therefore, the amount of pesticides is getting larger and larger, the toxicity is getting higher and higher, and the pesticide residues are getting more and more serious.
