谷子全膜双垄沟穴播技术效应研究——以宁夏盐池县为例

Effect Study of Millet under the Condition of all Membrane Double Ditch Covering Dibbling Technique——Taking Yanchi County of Ningxia Province for Example

为研究谷子在全膜双垄沟穴播技术条件下的水分效应、温度效应及其经济效益,提高水分利用率,对谷子全膜双垄沟穴播效应进行研究。结果表明,全膜覆盖比半膜覆盖平均增温1.3℃左右,比露地种植平均增温1.9℃左右。全膜覆盖水分利用效率较半膜覆盖提高1.65 kg/(mm·hm2),提高了20%,较露地种植提高2.85 kg/(mm·hm2),提高了40.4%。

In order to study water effect, temperature effect and economic benefit of millet under the condition of all membrane double ditch covering dibbling technique and improve the water use efficiency, effect study of millet under the condition of all membrane double ditch covering dibbling technique was studied. The study showed that the temperature of all membrane covering was higher 1.3 ℃ than half membrane, and higher 1.9 % than outdoor planting. Water production efficiency of all membrane covering was higher 1.65 kg/（mm·hm2） than half membrane covering, increased by 20%, and higher 2.85 kg/ （mm·hm2） than outdoor cultivation, increased by 40.4%.
