In addition, after granulation, it is dried into to moisture 1.0-3.0% (weight percent).
Below detailed description of the present invention:
Organic granular fertilizer provided by the present invention, belong to the compound manure field.It is with wild or propagate treated its effective constituent of using of marine alga artificially, is mixed and forms through concentrated, granulation process with organic raw material such as Lalgine, fermentation pig manure, dregs of beans and humic acids, clays.The weight percent of each component is: Seaweed Extract 15-25%, Lalgine 1.5-4.0%, fermentation pig manure 15-25%, dregs of beans 10-15%, humic acids 15-25%, clay 15-35%.
The effective constituent that contains each component in the organic granular fertilizer of Lalgine is respectively: the Seaweed Extract active substance can be up to 25%, and the potassium that not only can provide plants to need, have the effect of diseases prevention, expelling parasite, volume increase simultaneously; Lalgine accounts for 1.5%~4.0%, and Lalgine has passivation to the heavy metal in soil, stops the absorption of crop to heavy metal ion, has stronger water conservation, function of fertilizer retention, and extends fertilizer efficiency; The fermentation pig manure accounts for 15~25%, increases the content of the organophosphorus in fertilizer, and is rich in useful free microorganism; Organic effective constituent 5% in dregs of beans, it contains abundant plant protein, and organonitrogen is provided; Organic effective constituent 10% in humic acids,, it can improve soil, improves soil aggregate, eliminates and harden; Calcium oxide in clay (CaO) effective content 2.3%, magnesium oxide (MgO) effective content 3%.
Compared with prior art, the organic granular fertilizer that contains Lalgine of the present invention also has following technique effect:
At first, Seaweed Extract contains natural active matter, the growth that it can regulating plant; Lalgine has passivation to the heavy metal in soil, stops the absorption of crop to heavy metal ion; Lalgine has stronger water conservation, function of fertilizer retention, and extends fertilizer efficiency.
In addition, this fertilizer not only can provide the required nitrogen of crop, phosphorus, potassium, and can improve soil, improves soil aggregate, eliminates and harden, thereby improve the yield and quality of farm crop, melon and fruit, vegetables, strengthens disease-resistant, the resistance of agricultural-food.
