| 摘 要： | 研究结果表明,地膜覆盖栽培具有显著的增产效果,一般亩增47～144公斤,当季亩增益25.64～46.31元。增产主要依赖于穗粒数和千粒重的提高。覆膜具有增温、保墒、降低耕层含盐量,削弱光照,增大CO_2日较差,改善土壤物理性状和供肥能力等效应。生物学效应:促进了营养生长、培育壮苗,加快生育进程、改变了植株体内营养状况和吸肥节奏,使产品器官分化多、灌浆快、粒多、粒重、高产。并提出了栽培技术要点。

| Abstract: | The experiment results indicated that wheat yield was increased sig-nificantly by film mulching.On the mulched plots, the yield increased by47-144kg per mu, the net income increased by 25.64-46.31 Yuan per mubecause of increasing kernel number perspike and 1000 kernel weight. Thetemperiture, moisture and fertility of soil were increased by film mulch-ing. physical properties of the soil on the mulching plots were improved.The soil salt content in the plough layer was reduced, difference of CO_2within one day was increased by film mulching. Biological effect of thefilm mulching for wheat plant were:promoting vegetative growth, culturing strong seedling, speeding up theprocess of growth and development, changing nutritient status withinwheat plant and rhythm of nutrient absorption. |
