The present invention using by stalk powder, riverway sludge, cow dung mixing, Jing fermentable, it is deodorant, become thoroughly decomposed completely after plus
Enter other materials, crushed after being dried, then granulated, obtain wheat bio-fertilizer.
By zymotechnique in the present invention, cow dung, stalk are turned waste into wealth, it is to avoid cow dung cannot get effective process and become
The pollution sources of Cheng Xin, while avoiding the waste and pollution caused due to straw burning, stalk, cow dung are changed into harmless, steady
The fixed, organic fertilizer that is readily transported and stores and soil conditioner, then with riverway sludge, urea, calcium superphosphate, potassium breeze, life
Thing charcoal, zeolite powder, medical stone powder, bentonite coordinate, the nitrogen, phosphorus, potassium and other nutrients for needed for wheat growth is provided, and meet
The nutritional need of each growth phase of wheat.Wherein, stalk powder, potassium breeze, charcoal, citric acid, zeolite powder and bentonite are matched somebody with somebody
Close, the release of residual phosphorus in soil can be obviously promoted, improve absorption of the wheat to P elements, nitrogen and other trace elements,
Simultaneously energy fertilizing soil, increases fertilizer efficiency and fertilizer efficiency is permanent, absorbs beneficial to wheat, wheat growth-promoting;Charcoal is limited at high temperature
Oxygen is pyrolyzed, and most of carbon and inorganic ion in herbaceous plant are remained, improve soil with organic matter content and
Ion-exchange performance, the charcoal after sieving is loose structure, and specific surface area is big, and excellent adsorption is matched somebody with somebody with zeolite powder, bentonite
Close, on the one hand as the carrier of other materials in the raw material of wheat compound organic and inorganic fertilizer, with good dispersiveness with make
Graininess, increases fertilizer efficiency, and another aspect coordinates again with stalk powder, riverway sludge, cow dung, effectively improves soil texture, improves
Soil porosity, promotes soil aggregation, makes hardened loosing soil, improves soil aeration situation, and reduction nutrient is in soil
Leaching loss, with good retain water and nutrients ability, using its ion-exchange capacity and absorption property, can exchange in heavy metal,
Accelerate the degraded of harmful substance, effectively repair contaminated soil, while suppressing the quick change of pH-value in soil, improve soil
The ecological environment of microorganism and profitable strain in earth, maintains stablizing for soil ecosystem, promotes wheat growth and improvement
Wheat quality;Charcoal, zeolite powder, bentonite, fulvic acid, seaweeds, brassin lactones, polyethylene glycol cooperate, right
The growth of wheat has good adjustment effect, promotes the growth of wheat root, strengthens the metabolism of wheat, accelerates wheat
Absorption to nutrient and moisture, shortens the growth cycle of wheat, improves the resistance such as Drought-resistance in Wheat, cold-resistant, suppresses pest and disease damage simultaneously
Effectively alleviate the symptom that wheat is subjected to pest and disease damage, poisoning and freeze injury, improve the yield and quality of wheat.Proposed by the present invention one
Wheat compound organic and inorganic fertilizer is planted, by cooperating, each growth period is provided each storeroom for wheat in its raw material
The physicochemical property of soil is effectively improved while required various nutrients, soil fertility and sustainability is improve, be increased
The yield of wheat, improves the quality of wheat.
