摘要
根据田间试验资料 ,讨论了不同地膜覆盖方式对麦田土壤温度、土壤有效水分含量以及小麦生长发育产量形成的综合影响。结果表明 :地膜覆盖具有显著的增温效应 ,可使春小麦生育期提前 ,产量提高 ,并可提高土壤有效水分的利用率。吐鲁番市地膜春麦最佳栽培方案应采用“膜下条播、3月初播种、525万株/hm2基本苗”。
It is discussed that the integrate effect of the different cover modes of plastic film on the soil temerature,soil effective water and wheat growth and yield with field experiment data. the result show that the plastic film have salient warming effect,it can let spring wheat growing period advance and yield increase,and it can advance the use ratio of soil effective water.The best plant modes of spring wheat in Turpan is “seeding with 5250000 per hectare in strip under plastic film at the beginning of March.”
