泾惠灌区有小麦80万亩左右,占耕地60％以上。近年来,一些社队小麦亩产稳定在700—800斤,丰产田达千斤左右。为研究高产小麦耗水量和合理灌溉指标,本站从1979年至81年进行了有关试验。一、试验条件试验田前茬为玉米。于10月10日前后播种“灌选1号”,播量18斤/亩。宽窄行条播,宽行1尺,窄行5寸。每亩施土粪4大车,过磷酸钙100斤,氮肥折硫铵约100斤。耕层内土壤有机质1.35％,全氮0.1386％,全磷0.1443％,肥力中等偏上,土质中壤,1米土 Jing Hui irrigation area has about 800000 acres of wheat, accounting for more than 60% of arable land. In recent years, some social security teams have been able to stabilize the output of wheat at 700-800 kg per mu, yielding about 1000 kilograms. In order to study the water consumption of high-yield wheat and reasonable irrigation index, this station from 1979 to 81 carried out the relevant experiments. First, the experimental conditions before the crop crop of corn. Before and after October 10 sowing “irrigation election No. 1” sowing 18 kg / mu. Wide and narrow strip broadcast wide 1 foot narrow line 5-inch. 4 mu per application of soil manure, superphosphate 100 pounds, ammonium nitrogen about 100 pounds of ammonium sulfate. Soil organic matter in topsoil 1.35%, 0.1386% of total nitrogen, total phosphorus 0.1443%, fertility medium upper, soil medium, 1 m soil
