| 摘 要： | 以郑单958为试验材料,通过不同深松方式对玉米生育进程、土壤含水量、产量进行研究。结果表明:秋季深松好于春季深松,而春季深松好于夏季深松;深松40 cm的好于深松30 cm的;深松后的土壤在拔节前土壤含水量较低,拔节后土壤含水量升高,有利于玉米后期的生长发育;秋季常规垄深松、深度40 cm的处理产量最高为10 602.0 kg.hm-2。

| Abstract: | Using Zhengdan958 as test material,different pattern of subsoiling on maize growth process,soil moisture and yield were studied.The results showed that： subsoiling in autumn was better than in spring,while subsoiling in spring was better than in summer;subsoiling 40 cm depth was better than 30 cm depth;the moisture of soil by subsoiling treated was relatively low before the jointing stage and was increasing after the jointing stage,which were conducive to growth and development of the late stage;the highest yield occurred in the autumn conventional subsoiling with depth of 40 cm treatment,it was 10 602.0 kg·hm-2. |
