摘要
经反复试验和不断改进研制出适用于夏播玉米免耕播种的锄铲式倒T形开沟器和圆盘倒T形开沟器。经试验,在未耕地上破茬开沟,这两种开沟器均能达到应有的开沟质量,并具有独特的侧深位施种肥的优点。与传统播种机相比,免耕播种土壤水分散失少,玉米出苗早,出苗率高,生长健壮。
Two types of the inverted 'T' shape openers…chisel type and disk couter type, have been developed for no tillage planting summer corn. Experiments were conducted in undisturbed soil. The results show clearly that both of the openers have significant advantages in corn planting operations. Fertilizer can be place 3 cm to the side of the seed and 1 cm below seed. It is the special feature of the tow openers. No-tillage plant had indicated less moisture loss, higher seedling emergence percentage and stronger plant vegetative growth compared with traditional plant.
