The chitosan-coated controlled release fertilizer for saline-alkaline soil is made from chitosan, flyash, stalks, animal waste, furfural residue, citric acid residue, distillers' grains, desulfurization gypsum and the like, via the steps of fermenting, mixing, crushing, granulating, dissolving, spraying, perforating and the like; the wastes such as stalks, animal waste and furfural residue are fermented and then coated with chitosan such that the fertilizer may be released slow, fertility period is extended, fertilizer utilization rate is increased, saline-alkaline soil is better improved, and salt damage is relieved.
Description
Technical field
The present invention relates to agriculture field is and in particular to a kind of salt-soda soil chitosan coated controlled release fertilizers.
Background technology
Salt-soda soil refers to the soil that soil contains excess soluble salt.Saline-alkali soil be including solonchak, alkaline earth with
And different degrees of salinization, the general name of alkali-affected soil.Wherein solonchak refers mainly to chloride or the higher salinization soil of sulfate,
Soil is in alkalescence, but ph value is not necessarily very high.Alkaline earth refers to carbonate containing or the phosphatic soil of weight, and ph value is higher, and soil is in
Alkalescence, the content of organic matter of saline-alkali soil is few, and soil fertility is low, and physicochemical character is poor, and the anions and canons that crop is harmful to are many, crop
It is difficult to promote Seedling.
Saline and alkali land improvement method, mainly for eliminating unnecessary salinity in soil, reduces the alkalescence of soil, eliminates soil glue
The excessive Sodium by substitution of body.To reduce soil ph value, increase the content of soil with organic matter, improve Soil structure, increase
