据有关资料介绍,国内外农业高产稳产田的土壤有机质含量,一般都在3%以上,而我区的土壤有机质,南疆一般仅为0.7%左右,北疆也只有1.2—1.5%.与中等肥力的土壤所含养分相比,从去年十二个土壤普查试点县的资料分析,有25%的土壤缺氮,80%的土壤缺磷.因此,要提高单产,就必须增加土壤有机质和氮磷的含量.
According to relevant information, the content of soil organic matter in high and stable agricultural fields at home and abroad is generally above 3%, while the soil organic matter in our region is only about 0.7% in the southern part of Xinjiang and only 1.2-1.5% in the northern part of Xinjiang. Fertility of soil nutrients compared to 12 counties in last year’s soil census data analysis, 25% of the soil nitrogen deficiency, 80% of the soil phosphorus deficiency. Therefore, to improve yields, we must increase soil organic matter and nitrogen Phosphorus content.
