吨粮田（每公顷年产粮１５吨以上）生产中，化肥的作用非常重要。在新疆和田地区，小麦套种玉米吨粮田栽培中，小麦施化肥纯氮２２５ｋｇ／ｈｍ２，纯磷１０５ｋｇ／ｈｍ２，玉米施化肥纯氮２２５ｋｇ／ｈｍ２，纯磷７５ｋｇ／ｈｍ２，产量最高，经济效益最好，产投比为２．６２－２．７８：１，且土壤主要养分含量呈上升趋势。
The role of chemical fertilizers in the production of tons of grain (more than 15 tons of annual output per hectare) is very important. In the Hetian region, wheat was planted with 225 kg / hm2 of pure nitrogen and 105 kg / hm2 of pure phosphorus, 225 kg / hm2 of pure nitrogen and 75 kg / hm2 of pure phosphorus, with the highest yield and the most economic benefit Well, the ratio of production to investment is 2.62-2.78: 1, and the main nutrient content in soil is on the rise.
