中文摘要	针对辽宁西部半干旱区春玉米节水高效生产中存在不同滴灌方式选择不合理的问题,为了探究更适宜的滴灌布置形式,以裕丰303为供试材料,在中国科学院沈阳应用生态研究所旱作农田水循环试验站通过田间试验,设置膜下滴灌(MD)、浅埋滴灌(BD)和地表无膜滴灌(SD)3个处理,采用Logistic及其修正的Logistic方程分别拟合株高、籽粒灌浆及叶面积指数生长动态,分析了3种不同滴灌方式对春玉米出苗率、产量及其构成要素、水分利用效率及经济效益等指标的影响。结果表明:BD处理的出苗率比SD提高2.81%,比MD降低3.95%;在Logistic方程拟合下,BD、MD及SD处理春玉米株高最大增长速率及其出现时间分别为6.68,7.86,6.50cm·d~(-1)和播种后44,40,45d, BD粒重增长率最大时间比SD提前3d,增长率最大值提高14.22%,比MD延迟1d,增长率最大值降低0.43%,同时,BD下叶面积指数最大值比S D提高3.88%,比MD降低9.10%;BD处理产量达11962.54kg·hm~(-2),较SD处理显著增产9.53%,较MD处理增产4.00 %,BD与MD相比产量差异不显著;BD的水分利用效率较SD提高12.67%,较MD降低0.59%;BD的净效益比SD增加37.74%,比MD增加 25.24%。综合认为浅埋滴灌下春玉米产量高于膜下滴灌和地表无膜滴灌,且解决了膜下滴灌春玉米出苗期引苗问题,也避免了残膜的环境污染问题,净效益高于膜下滴灌和地表无膜滴灌,能更好实现春玉米的节水、增产、增效,适宜在辽西及类似半干旱地区推广应用。
英文摘要	In view of the unreasonable selection of drip irrigation methods in the water-saving and efficient production of spring maize in the semi-arid region of western Liaoning Province, in order to explore a more suitable drip irrigation type, Yufeng 303 was used as the test material, and the field experiment was carried out in Fuxin. Three kinds of drip irrigation methods were set up, including mulched drip irrigation (MD), shallow subsurface drip irrigation (BD) and surface drip irrigation (SD). Logistic equation and its modified form were separately used to plant height, grain filling and leaf area index dynamic growth, then, the effect to three different drip irrigation modes on seedling emergence of spring maize, yield and its components, water use efficiency and economic benefit was analyzed. The results showed that the emergence rate of BD treatment was 2.81% higher than SD, and 3.95% lower than MD. Under the Logistic equation fitting, BD, MD and SD treatment of spring maize plant height maximum growth rate and its occurrence time were 6.68, 7.86, 6.50cm·d~(-1) and sowing after 44, 40, 45d, The largest grain weight of BD increased 3d ahead of SD, and maximum growth rate increased by 14.22%, than the MD delay 1d, reduces the maximum growth rate of 0.43%. At the same time, the maximum value of leaf area index under BD was 3.88% higher than that of SD, 9.10% lower than that of MD. The yield of BD treatment was up to 1,1962.54kg·hm~(-2), which was 9.53% higher than that of SD treatment and 4.00% higher than that of MD treatment, and the yield difference between BD and MD was not significant. The water use efficiency of BD was 12.67% higher than that of SD and 0.59% lower than that of MD. The net benefit of BD increased by 37.74% compared with SD and 25.24% compared with MD. Therefore, spring maize yield under BD was higher than that of MD and SD, and the maize seedling problem under MD were solved spring maize seeding stage also can avoid the environmental pollution of the residual film, net benefit is higher than MD and SD. The BD can better realize the increasing yield, saving water for spring maize, which is suitable for application in western Liaoning and semi-arid region.
