为了比较不同耕作方式和工作深度对玉米生产的影响，在华南农业大学农场进行了两组对比试验，试验土壤为沙壤上和粘壤土，试验作物为玉米。第一组试验中安排了5种耕作方式，分别为犁耕加圆盘耙（MB＋DH），凿形耕（CH），圆盘粑两次（DH2），旋耕（RT）和不耕（NT），第二组试验中安排了2种耕作方式，犁耕加圆盘耙（NDL）和犁耕、圆盘耙加深松（NL）。试验结果表明，不同的耕作方式和工作深度对土壤容重、土壤耕作阻力、土壤含水量、玉米生长情况和产量均有不同影响。在第一组试验中，省形耕（CH）效果最好，在第二组试验中，深松（NL）比不深松（NDL）好。本研究表明，应根据不同作物、不同土壤采取不同耕作方式，以增加作物产量。
In order to compare the effects of different tillage methods and working depth on maize production, two comparative experiments were conducted on the farm of South China Agricultural University. The soil tested was sandy soil and clay loam, and the experimental crop was maize. In the first experiment, five farming methods were arranged: MB + DH, chisel, DH2, RT and NT ). In the second experiment, two kinds of farming methods were arranged: plowing with disc harrows (NDL) and plowing, and disc harrowing with deepening pine (NL). The results showed that different tillage methods and working depth had different effects on soil bulk density, soil tillage resistance, soil water content, corn growth and yield. In the first experiment, the provincial tillage was the best, and in the second experiment, deep plowing (NL) was better than no-plowing (NDL). This study shows that different farming methods should be adopted according to different crops and different soils to increase crop yield.
