盖膜对地麦生长发育的影响

 地麦盖膜栽培,其植株的相对含水量和土壤绝对含水量都显著增加,提高了土壤养分的利用率,而使植株的根量和根的体积增加,根系的生理活性增强。同时减轻了干旱对地麦正常生理功能的影响,较好地解决了缺水、少肥问题,显著地提高了产量。

Influence of Film-mulching on Growth and Development of Upland Wheat

We have made investigations of the culture of upland wheat under film-mulching conditions. The results showed that the relative moisture content in the plant and the absolute moisture content in the soil increased, significantly so that the utilization ratio of soil nutrient became high. It was also found that the number of plant roots, and the volume and the physiological activity of roots were increased under film-mulching conditions. Thus, the seed yield was raised significantly because the interference from drought in normal physiological functions of upland wheat was alleviated and the influence of water deficiency and fertilizer insufficiency on wheat growth weakened.
