Fertilizer composition by using humic acid for plant growth promoting

摘要

The present invention relates to a kind of fertilizer compositions for promoting plant growth, specifically, it is related to a kind of fertilizer composition for promoting plant growth, improves yield, pass through combination fulvo acid and various types of nitrogen, and more specifically, it is related to a kind of fertilizer composition, wherein water-soluble humic acid input ratio originates from leonardite, the urea nitrogen of nitrogen source, the type of ammonia nitrogen and nitrate nitrogen according to control nitrogen source, to promote plant growth and increase yield. Therefore, the productivity of plant improves and the considerations of diversified nitrogen source absorption plant and passes through the humic acid in synergistic effect with regard to conventional liquid type nitrogenous fertilizer. When the fertilizer composition is manufactured according to one embodiment, dilutes and be coated onto Btassica gumhar by injection and foliage dressing while cultivating in Brassica plants gumhar pot, gumhar is the growth that Brassica genus is promoted to and increases yield. In particular, injection promotes to be confirmed as being applied to product, because injection promotion is more more convenient than blade. Based on the result,The fertilizer composition promotes growth and increases yield Brassica genus gumhar and/or other leaf vegetables as material. ;The 2015 of copyright KIPO submissions
