摘要
为探讨不同覆膜方式对黄土高原地区旱地谷子生长特性及产量的影响。以谷子为研究对象,对生物降解地膜覆盖种植(M1)、渗水地膜覆盖种植(M2)、黑色地膜覆盖种植(M3)、白色地膜覆盖种植(M4)、双垄沟地膜覆盖种植(M5)与裸地种植(CK)六种处理的土壤水热环境、叶绿素含量、株高、地上部生物量累积及产量的影响进行分析,并使用灰色关联法进行综合评价。结果显示:(1)M4和M5覆膜处理在拔节期和成熟期显著提高了12.0%~23.8%的土壤含水量和1.0%~23.8%的土壤温度(p<0.05);(2)M5覆膜处理显著提高了谷子全生育期12.4%~34.9%的株高、8.3%~11.7%的叶绿素含量、25.7%~241.6%的地上部生物量累积及118.4%的千粒重(p<0.05);(3)M4和M5处理分别较CK增产77.7%和121.0%;(4)灰色关联综合评价值为CK(0.57)、M1(0.74)、M2(0.67)、M3(0.61)、M4(0.75)和M5(0.88)。因此,各覆膜处理均能够调节旱地谷子的生长及促进产量的形成,其中覆膜表现效果依次为M5、M4、M1、M2和M3。
To explore the effects of different mulching methods on the growth characteristics and yield of foxtail millet in dryland areas of the Loess Plateau,this study evaluated six treatments:biodegradable film mulching(M1),water-permeable film mulching(M2),black plastic film mulching(M3),white plastic film mulching(M4),ridge-furrow plastic film mulching(M5),and bare land cultivation(CK).The effects on the soil hydrothermal environment,chlorophyll content,plant height,aboveground biomass accumulation,and yield were analyzed,and a comprehensive evaluation was conducted using the grey relational analysis method.The results showed that(1)M4 and M5 treatments significantly increased soil moisture by 12.0%~23.8%and soil temperature by 1.0%~23.8%(%p%<0.05)at both the jointing and maturity stages.(2)M5 significantly enhanced plant height by 12.4%~34.9%,chlorophyll content by 8.3%~11.7%,aboveground biomass accumulation by 25.7%~241.6%,and thousand-kernel weight by 118.4%(%p%<0.05)throughout the growth period.(3)Compared to CK,M4 and M5 increased grain yield by 77.7%and 121.0%,respectively.(4)The comprehensive grey relational grades for treatments were:CK(0.57),M1(0.74),M2(0.67),M3(0.61),M4(0.75),and M5(0.88).Overall,all mulching methods effectively improve foxtail millet growth and yield in dryland conditions,with the performance ranking as follows:M5>M4>M1>M2>M3.
