(一)Efficacy of fertilizer: the nutrition, natural minerals, growth regulatory agent contained in this product can promote the cleavage and elongation of plant cells, intensify the metabolism, speed up development of roots, and improve the ability to absorb water and nutrition, enhance anti-adversity ability, improve quality of grains, and output.
(二)Anti-adversity ability: This product contains many sea life activity matters, algal sugar, iodine, and etc at a proper ratio. It can inhibit powder mildew, grew mildew, and red spiders effectively especially for glasshouse red spiders, Corticium and other diseases.
