摘要
为了探讨辽宁中部地区大豆节水优质灌溉模式,在有滑动遮雨棚的测坑中进行田间试验,研究了常规沟灌、固定沟灌和交替沟灌3种灌溉模式对大豆的性状、产量及品质的影响。研究结果表明,交替沟灌比常规沟灌、固定沟灌更能促进大豆的根和茎粗的生长;其水分利用效率比常规沟灌和固定沟灌分别提高了25.4%和13.3%,产量提高了13.0%和7.0%,同时明显提高了大豆的品质,实现了节水增产和提高品质的目标。表明交替灌溉为最优灌溉方式。
To explore the water-saving and high-quality irrigation pattern of soybean in the central region of Liaoning Province, a field experiment was carried out to evaluate the effects of different partial root-zone irrigation patterns, i. e, alternate furrow irrigation （AFI）, fixed furrow irrigation （FFI） and conventional furrow irrigation（CFI） on soybean characters, yield and quality in Water-saving Irrigation Comprehensive Ground of Water Conservancy College of Shenyang Agricultural University in May-October, 2010. The experiment was made in the measuring pit with sliding block canopy. The results show that alternate furrow irrigation can more promote the growth of the soybean root and stem. Compared to the fixed furrow irrigation and conventional furrow irrigation, the water use efficiency was increased by 25.4 % and 13.3 %, respectively. While yield was improved 13.0% and 7.0%, respectively. Meanwhile the quality of soybean was obviously increased, and the objective of saving-water increase and improving quality was realized. The alternate furrow irrigation is the optimal irrigation method.
