| 摘 要： | “增温说”和“调水说”是指导地膜玉米最佳播期的基本理论。在湿润、半湿润生态类型区和干旱、半干旱生态类型区的水浇地、二阴地 ,应用“增温说”;在半干旱生态类型区的旱作田 ,应用“调水说”。经多年的试验和调查表明 ,在半湿润生态类型区 ,应用“增温说”指导地膜玉米最佳播期增产 6 9.2 % ;在半干旱地区 ,应用“调水说”指导地膜玉米最佳播期增产6 0 .0 % ,而应用“增温说”播期只增产 15 .7% ,比“调水说”播期减产 14 .4 %。

| Abstract: | The theory of temperature raising and the theory of precipitation regulating are basic in guiding the optimum sowing time for the corn growing by plastic film.The former is applied to the ecotype of damp and semi damp soil and irrigated or half shaded land in arid and semi arid area, while the latter was suitable for the ecotype of dry farming land of semi arid area.The results of experiments and investigations in many years showed that in the semi damp soil, the output had been increased by 69 2% when the former is used to guide the optimum sowing time for the plastic film corn, and in the semi arid area and the yield of corn increased by 60 0% when the latter was used, for, when used, the output will increase only by 15 7% and dropped by 14 4% less than the latter. |
