两法种植是指山坡地水平沟种植和川台、塬地垄沟种植.这项技术能使跑土、跑水、跑肥的“三跑田”变为“三保田”,从而使小麦增产. 1.山地水平沟种植法在5～20度的坡耕地上,沿等高线采用2B-2畜力沟播机,自上而下一次性完成开沟、起垄、施肥、播种、复土、镇压6道工序.开沟深度一般为15cm以上,沟宽15cm以上,沟距40～60cm,垄高7～10厘米.施肥深度要比种子深10～13cm,亩播量4.5～5 kg.播种深度4～6 cm,播种后沟中小行距为10cm.
The cultivation of two laws refers to the cultivation of horizontal furrows on hillsides and the planting of furrows in Chuantai and Heyuan, which can change the “three fields” of soil-running, running water and running fertilizer into “three conservation fields” so as to increase the yield of wheat. 1. Mountain horizontal trench cultivation method In the slope of 5 ~ 20 degrees of cultivated land, along the contour line using 2B-2 livestock ditching machine, from top to bottom to complete a one-time ditching, ridge, fertilization, sowing, Cracks 6 processes.Drainage depth is generally more than 15cm, the width of more than 15cm, furrow spacing of 40 ~ 60cm, ridge height of 7 to 10 cm. Fertilizer depth than the seeds of 10 ~ 13cm, mu sowing 4.5 ~ 5kg. Depth of 4 ~ 6 cm, after sowing the small row spacing of 10cm.
