摘要
为探讨不同覆盖措施对春玉米产量和水分利用效率的影响,采用随机区组设计,设置地膜覆盖、可降解膜覆盖、秸秆覆盖及无覆盖4个处理,对比不同处理下春玉米的穗粗、穗长、穗粒数、百粒质量、总产量和水分利用效率。结果显示,地膜覆盖处理显著优于其他处理,春玉米穗粗6.17 cm、穗长22.82 cm、穗粒数达43.57粒、百粒质量33.57 g、总产量为7346.50 kg/hm^(2);水分利用效率达到3.92 kg/m3,较对照组提高了29.37%。结果表明,地膜覆盖是一种有效的农业覆盖措施,可显著提升春玉米的产量和品质,提高水分利用效率。研究结果为农业生产中选择合适的覆盖措施提供了科学依据。
To explore the effects of different covering measures on the yield and water use efficiency of spring maize,a random block design was adopted,and four treatments,namely plastic film covering,degradable film covering,straw covering and no covering,were set up.The ear diameter,ear length,number of grains per ear,mass per 100 grains,total yield and water use efficiency of spring maize under different treatments were compared.The results showed that plastic film mulching was an effective agricultural mulching measure,which could significantly increase the yield and quality of spring maize and improve water use efficiency.The research results provided a scientific basis for choosing appropriate covering measures in agricultural production.
