通过对宁夏西吉县沙沟乡机修水平梯田定位试验分析得出,其培肥增产技术措施是:(1)农牧结合,增加有机厩肥投入;(2)粮豆草轮作,实行秸秆还田;(3)引洪漫地;(4)深耕改土;(5)合理施用氮磷化肥。并在小麦、胡麻、地膜玉米、马铃薯4种作物上定量分析得出:1hm2春小麦≥4500kg施纯N218.1kg/hm2~283.5kg/hm2,施纯P2O5100.5kg/hm2~117.0kg/hm2;1hm2胡麻产量≥2250kg施纯N244.5kg/hm2~303kg/hm2,施纯P2O585.5kg/hm2~126.0kg/hm2;1hm2地膜玉米产量≥9750kg,施纯N147.0kg/hm2~228.0kg/hm2,施纯P2O569.0kg/hm2~115.5kg/hm2;1hm2马铃薯产量≥22500kg施纯N132.0kg/hm2~231.0kg/hm2,施纯P2O566.0kg/hm2~117.0kg/hm2。
Through the positioning test of the horizontal terrace in mechanized repair of Shagou Township, Xiji County, Ningxia, the technical measures for increasing yield of cultivated land are as follows: (1) Combining agriculture and animal husbandry, increasing the input of organic manure; (2) ; (3) lead flood; (4) plowing and soil improvement; (5) rational use of nitrogen and phosphorus fertilizer. Quantitative analysis on 4 crops including wheat, flax, mulched corn and potato showed that: 1hm2 spring wheat ≥4500kg applied pure N218.1kg / hm2 ~ 283.5kg / hm2, applied pure P2O5100.5kg / hm2 ~ 117.0kg / hm2 ; 1hm2 flax yield ≥ 2250kg applied pure N244.5kg / hm2 ~ 303kg / hm2, applied pure P2O585.5kg / hm2 ~ 126.0kg / hm2; 1hm2 plasticized corn production ≥9750kg, applied pure N147.0kg / hm2 ~ 228.0kg / Hm2, applying pure P2O569.0kg / hm2-115.5kg / hm2; yielding 225kg / hm2 ~ 231.0kg / hm2 for 1hm2 potato and applying pure P2O566.0kg / hm2-117.0kg / hm2.
