在大豆生产中,施肥水平越来越高。因此,对大豆的施肥方法也提出了新的要求。实验证明,侧深施肥比同位施肥可提高发芽率37.5%,因此,如何实现大豆播种的侧深施肥,就成了农机战线的一项重要课题。我场经过几年的试验,搞出了两种侧深施肥开沟器。一种是48行开沟器片和圆盘耙片组合式开沟器。就是用48行开沟器总成,保留一片开沟器不动,另一片开沟器圆盘换用直径为φ310毫米的圆盘耙片,安装方法和原48行开沟器装配方法相同。卸掉原来的分种器,用自制的铁皮卷成的圆筒式输种管代替。播种时,开沟器圆盘开的沟施肥,圆盘耙片开的沟播种。形成侧5厘米、深2厘米的侧深施肥装置,具体构造
In soybean production, fertilizer levels are getting higher and higher. Therefore, the method of fertilization of soybeans also put forward new requirements. Experiments show that the side of the deep fertilization than the same position fertilization can increase the germination rate of 37.5%, therefore, how to achieve the side of the soybean sowing fertilization, agricultural machinery has become an important frontline issue. After several years of my field trials, come up with two kinds of deep side fertilizer opener. One is a 48-row opener and disk harrow combiner opener. Is to use 48 rows opener assembly, keep a opener does not move, and another opener disk with a diameter of φ310 mm disc harrow, the installation method and the original 48 row opener assembly method the same. Disassemble the original splitter, with a homemade roll into a cylindrical tube instead. Sowing, opener ditch ditch ditch fertilization, disc rake open ditch seeding. Side of the formation of 5 cm deep, 2 cm deep fertilization device, the specific structure
