滦县一带的花生大部分种植于滦河两岸的沙质土壤上,花生品质好,历年都种植20多万亩,是河北省主要油料基地之一。县农具所从1975年就着手研制花生播种机,由于胶轮小拖在沙地作业滑转率高,不能正常作业,而大拖牵引的多行播种机在沙岗坡地又不适应。县农具所针对这种情况逐步研究改进,于1979年研制成功HB 3型花生播种机(见图)。在今年花生播种和夏播中,用小履带拖拉机牵引,两
Most of the peanuts in Luanxian County are planted on the sandy soil on both banks of the Luan River. The quality of peanuts is good. Over 200,000 mu have been planted over the years and it is one of the major fuel bases in Hebei Province. County farm tools from 1975 on the development of peanut planter, rubber tire small drag in the sand work slip rate is high, can not be normal operation, while the big drag towed multi-line planter in Shagang slope does not meet. County farm tools for this situation gradually improve the study, in 1979 developed a successful HB 3 peanut planter (see photo). In this year’s peanut planting and summer sowing, with a small track tractor traction, two
