摘要
为研究中耕深松对土壤蓄水及玉米根系生长和产量的影响,应用沈阳农业大学工程学院研制的1HS-1.2型中耕深松机,在位于阜新县他本镇马蹄营子村的国家"863"项目试验基地进行了玉米中耕深松试验,通过深松前后土壤含水量变化及玉米长势的对比,研究了中耕深松对不同时期土壤含水量以及玉米根系生长发育和玉米产量的影响程度。结果表明:中耕深松后土壤的水分含量比未深松土壤的水分含量明显增加,中耕深松后玉米根系的根长明显大于未深松根系的根长,中耕深松后玉米的产量每公顷增加幅度为21%。
In order to study the influence of subsoiling on the characteristics of storing moisture of soil,growth of maize＇ root and output of maize.The experment was carried in ＂863＂ testing farmland at Matiying village in Taben town Fuxin county Liaoning Province on 1HS-1.2 subsoiler deveoped by Shenyang Agricultural University,contrasting the moisture of soil and growth of maize which are subsoiled before and after,studying on the degree of influence of subsoiling to the moisture of maize＇s soil of different stages and growth of maize＇ root.The results showed that the moisture of soil subsoiled increased significantly than that of no subsoiling soil.The root length of maize in subsoiled treatment was significantly greater than that of no subsoiling maize,output of maize subsoiled increased of 21% per hectare.
