土壤处理剂在地下滴灌条件下对土壤水分、大豆产量以及品质的效应

Effects of Soil Finishing Agent-Guilspare on Soil Moisture and Yield and Quality of Soybean Under Subsurface Drip Irrigation

为了促进干旱半干旱地区大豆的生产,解决大豆生产过程严重缺水问题,采用模拟大田的试验方法,进行土壤处理剂——Guilspare在地下滴灌条件下对土壤水分、大豆产量以及品质的试验。结果表明:土壤处理剂喷施浓度2%的处理在50%,75%,100%灌水量下平均土壤含水率分别较对照组高22.04%,36.67%,13.15%;产量分别较对照组增产11.49%,7.83%,16.02%;蛋脂总量分别较对照组增加6.95%,0.33%,4.53%。体现了该土壤处理剂较好的保水效果和一定的增产功效与改善大豆品质的性能。最终分析比较得出土壤处理剂喷施浓度2%的处理在50%灌水量下大豆品质最佳,水分利用效率最高为7.60 kg/(mm.hm2),其节水增产、改善大豆品质综合方面效果最为显著。

In order to enhance production of soybean in semi-arid area and find new way to solve problems of drought and water shortage of soybean growth process, the study used simulate field plot experiment to find soil finishing agent＇s impact on soil moisture, yield and quality of soybean with the subsurface drip irrigation. The results indicate that, under the condition of 2% spraying concentration and 50%, 75%, 100% duty, average soil water content were 22.04% ,36.67% ,13.15% higher than contrast respectively; yield increased at 11.49%,7.83%,16.02%;total content of protein and oil were 6.95%,0.33%,4.53% than contrast respectively. So it had better water retention and same effect of production increasing and function of improving quality of soybean. At last, under condition of spraying concentration 2% and 50% duty, quality of soybean was the best, WUE was 7.60 kg/（mm ·hm^2） as maximum, the integrative effect of production increasing and water saving and quality improving of soybean were obvious.
