膜下滴灌的不同补灌处理对花生田间水分、耗水量及产量的影响
The Impact of Different Supplemental Irrigation treatments on Water Content, Water Consumption and Yield in Peanut Field under Film-mulched Drip Irrigation
摘要
Abstract
In order to resist the frequent drought in the semi-arid regions of the western part of Liaoning Province and to solve the problem of peanut product reduction, a preliminary study on drip irritation and supplemental irritation under the film-mulched on peanut has been conducted under the condition of natural precipitation. The results showed the water content of shallow soil and peanut water consumption was significantly influenced by supplementary irrigation. The water content in the deep soil (10cm lower than the surface) was varied substantially between 10%-25%. While the water content in the 50cm lower deep soil was varied slightly between 19%-20%. By comparison analysis, it could be found the less supplementary irrigation norm, the less water consumption, so CK treatment is the least, which is 247.35 mm. The increase of supplementary irrigation norm and frequency of supplementary irrigation has certain effect on the increase of peanut production. Among these increases, treatment T3I3 was the most significant, which is 40.5% higher than that of treatment CK. While the water use efficiency was the highest (2.28kg•m-3). Therefore, in the low flow year with 300mm rainfall, the best supplementary irrigation period and supplementary irrigation norm should refer to treatment T3I3. It should be 4.5mm before sowing;irrigating twice in the seedling stage and 4.5mm every time. In the period of blossom, irrigating twice and 9.75mm per time, while in fruiting period, there should be one time for irrigation with the amount of 12.0mm. Overall, the formulation of the irrigation and supplementary irrigation system has substantial significance for the increase of peanut production.关键词
