Abstract:
     The present invention relates to a special purpose complex fertilizer for soline-alkali soil. According to the characteristics of soline-alkali soil it mixes natural zeolite with peat containing organic matter and humic acid and a right amount of fertilizer containing nitrogen and phosphorus elements, and adds a small amount of trace element Zn which is requisite for plant growth. When it is applied in soline-alkali soil, it can change said soil structure and reduce the harm of pernicious ions in the soil to plants and preserve moisture and fertility, therefore the yield of crops can be increased generally by 15-30%.
