在氨水深施上,一般用人工挖窝深埋,对肥效的利用率虽有很大提高,但费工大,进度慢;利用条播机沟施一次可施许多行,虽则进度快,但不能达到施深埋严的要求,而且往往因行子不规格、不端直易撞伤麦苗,洒湿茎叶,损坏作物。围绕这些问题,经过我们反复试验,利用步犁原理,用一根φ22毫米元钢35公分作犁头,前面打成扁形三角尖,后尾钻上一个内径φ10毫米5公分深的孔作为氨水输送下来向后吐出的通道。犁臂用0.8公分厚的板铁焊接。改制的氨水深施犁,造型
In the deep application of ammonia, the general use of artificial dig deep nest, although the use of fertilizer efficiency has greatly improved, but the big flies, slow progress; use of seed drill ditch one application can be applied to many lines, although the progress is fast, but can not be achieved Shi deep buried strict requirements, and often due to the line is not standard, easy to hit straight injured wheat seedlings, sprinkle wet stems and leaves, damage to crops. Around these problems, through our repeated tests, the use of plow principle, with a φ22 millimeter steel 35 cm for the plowshare, the front labeled flat triangular tip, the rear end of an inner diameter φ10 mm 5 cm deep hole as ammonia transport Spit down the channel down. Plow arm with 0.8 cm thick plate welding. Modified ammonia deep plow, modeling
