By on see, use the technical scheme of the embodiment of the invention, this fertilizer promptly contains common mineral manure, and the required principal element of the plant in mineral manure: the ratio that the weight content of nitrogen, phosphorus, potassium accounts for total fertilizer is not less than 20%, can guarantee the main needs of plant-growth.
In addition, also contain in this fertilizer by the weight proportion humic acids that to be 70% brown coal, 30% waste tobacco powder obtain through repeatedly composite bacteria fermentation, this humic acids has the base-exchange energy, the active acidity and the hydrolytic acidity of soil are decreased, make soil be tending towards neutral, improve the reactivity of soil, more help the development growth of plant;
In addition, contain humic acids in this fertilizer, it contains a large amount of mineral substance, because the loading capacity of mineral substance and abundant commutative base cation, and have extremely strong cation exchange capacity and an abundant commutative base cation, and has a reversible cation exchange property, when in the soil during nitrogen ionic excessive concentration, also can get up excessive nitrogen ion storage in the hole of mineral and duct, when nitrogen ionic concentration is low, carrier will be stored in nitrogen ion exchange in hole and the passage usefulness of crop alimentary altogether of coming out from hole and passage, make the nitrogen ion obtain bigger improvement, execute quick-acting fertilizer and be modified as long-acting fertilizer with the defective of temperature volatilization loss, efficient fertile.
In addition, nitric nitrogen has and is difficult for being absorbed by soil, the easy performance of losing with current, and the fertilizer of the application embodiment of the invention, because this humic acids has the cation exchange capacity that particle slows down characteristic and absorption property increase soil, not only help recovering and improving organic fertility of soil, the nitrogen ionic adsorption that can also lose with current is in hole and passage, can delay nitrogen and in soil, change into nitric nitrogen, and catch ammonium ion and the nitrate radical that the organism classification with nitrogen produces, suppress the volatilization of ammonia gas and synthesizing of nitric acid, play the effect of " fixed nitrogen guarantor ammonia ".
In addition, phosphorus has in soil and to be difficult for moving, thereby and absorbed the fixing characteristic that loses fertilizer efficiency (even more serious in acid soil especially) by soil, and since contain in this fertilizer have base-exchange can humic acids, can
In addition, phosphorus has difficult moving in soil, thereby and absorbed the fixing characteristic that loses fertilizer efficiency (even more serious in acid soil especially) by soil, and the humic acids with basic ion of the fertilizer in the present embodiment can reduce the acidity of soil, helps improving the rate that is utilized of phosphorus.
In addition, in weather sweltering heat, the big and concentrated torrid zone, the subtropical zone of rainfall, soil leaching is strong, it is commonplace to lack the silicon situation, and the humic acids of the fertilizer of the embodiment of the invention contains more silicon-dioxide, to improving soil quality, the trophic structure of balanced soil is very favourable to the growth of farm crop.
In addition, owing to also contain in the present soil generally the middle trace element of disappearance (such as copper, zinc, manganese, boron, iron, molybdenum, magnesium etc.) in the fertilizer of present embodiment, the nutritive element structure that helps improving the soil makes it balanced more.
