我区中海拔温热地带(海拔1300～1700米)稻麦两熟区,小麦复种及增产潜力很大,为使田麦栽培措施逐步由定性转为定量化,1989～1990年我们进行了田麦高产低耗优化栽培试验,以期为大面积规范化栽培提供侬据。一、供试品种和试验的基本情况供试品种为“川麦20”。试验安排在临沧县城区嘎乡办事处,大田面积2.4亩,海拔1460米,土壤为沙胶泥壤土。肥力中上等,土壤pH5.4,有机质含量4.99％,全氮0.22％,全磷0.17％,全钾1.03％;速效氮15.9mg/100克土,速效磷
In our district, in the warm and temperate zone (1300 ~ 1700 m above sea level), the double cropping system of wheat and wheat, wheat multiple cropping and potential for increasing yield are very large. In order to make the cultivation measures of field wheat gradually qualitatively quantitative, from 1989 to 1990, Low-cost optimization of cultivation experiments, with a view to large-scale standardized cultivation to provide Lennon. First, the test varieties and test the basic situation for the test varieties as “Chuanmai 20.” Experimental arrangements in Lincang County Ga Township Office, field area of 2.4 acres, 1460 meters above sea level, the soil is clay sand soil. Fertility in the finest, soil pH5.4, organic matter content of 4.99%, 0.22% of total nitrogen, total phosphorus 0.17%, total potassium 1.03%; available nitrogen 15.9mg / 100 grams of soil, available phosphorus
