1979～1980年,我们研制的能进行全面深松并同时施肥的浅翻深松施肥犁,总耕深可达30～35厘米(浅翻12～23厘米,深松8～12厘米),亩施肥量几十斤至千斤以上(有机肥和碳铵等各种常用肥料)。 一、浅翻深松犁 根据引黄灌区农业上“秋翻地春免耕”和“深施肥浅播种”的耕作要求,并充分发挥现有农机具的作甩,我们在不破坏L—5—35牵引五铧犁的基础上,将犁壁抬高(前端抬高110毫米,后端抬高150毫米),在犁壁和犁铧之间加一块犁柱护板(在其前部焊有限土板,防止生土翻上来;在其中部开有漏土窗口,以减小阻力),即可实现上翻下松。仅用料10公斤左右(不包括施肥装置),既省钱,又可一机多用。(如图示)
From 1979 to 1980, we developed shallow and deep pine fertilization plows that can be fully subsoiled and fertilized at the same time. The total tillage depth can reach 30-35 cm (12-23 cm in shallow and 8-12 cm in depth), Feeding tens of kilograms to more than kg (organic fertilizer and ammonium bicarbonate and other commonly used fertilizers). First, the shallow plowing deeper plowing According to the Yellow River irrigated agriculture “Qiudianye spring zero tillage” and “deep fertilization shallow sowing” farming requirements, and give full play to the existing farm machinery for rejection, we do not undermine the L-5 -35 On the basis of a 5-plow towing, raise the plow wall (front 110 mm, rear 150 mm) and add a plow guard between the plow wall and the plowshare (limited in front of the plow Soil board to prevent raw soil turned up; open in the middle of a leaky window to reduce resistance), you can achieve the turn-down. Only about 10 kg of materials (excluding fertilization device), not only save money, but also a multi-purpose machine. (As shown)
