旱地胡麻不同覆膜方式试验初报

Preliminary Report on Test of Different Plastic Film Mulching Modes for Dryland Flax

在宁夏固原市原州区开展了旱地胡麻不同覆膜方式试验研究,结果表明,地膜覆盖种植可有效增加土壤温度,保持土壤水分,降低土壤水分蒸发,提高出苗率,增加胡麻产量。全膜覆土穴播栽培、覆膜不覆土穴播栽培、膜侧栽培比常规种植分别增产41.94%、12.5%、23.39%,增产效果显著。建议在旱地胡麻生产上,推广应用3种覆膜栽培方式,全膜覆土穴播栽培模式应在生产中大力推广应用。

A test of different plastic film mulching modes for dryland flax was conducted in Yuanzhou district in Guyuan municipality in Ningxia. The result showed that the plastic film mulching cultivation could effectively increase the soil temperature, preserve the soil moisture, reduce the soil water evaporation, improve the germination rate and increase the yield of linseed. The yields with the film whole-mulching and soil covering cultivation, film mulching and no soil covering bunch planting cultivation and film side cultivation were 41.94%,12.5% and 23.39% higher than that with the conventional planting and the yield-increasing effect was significant. It is suggested that the three plastic film mulching cultivation modes should be extended and applied and the film whole-mulching and soil covering cultivation mode should be extended and applied widely in production.
