在水稻田间试验和大田栽插中,一般用绳子、木桩、量尺等定点定边栽秧,手续繁杂,既不省工,也易造成误差,不易保证规格。近年我们采用“划格器”划定水稻田间试验小区,实施较方便,节省了用工,减少了田间试验误差,提高了质量和进度。一块试验田约半小时就可划好,一般一个劳力每天可划10—20亩。具体作法是:试验田犁耙整绒整平后,保持现泥浅水,用需要的规格的“划格器”,纵横划格,按各设计试区长、宽,四角插上标记,并留好走道,插上各 In paddy field trials and field planting, the general use of ropes, stakes, measuring tape and other fixed-point Dingbian planted, complicated procedures, neither labor, but also easy to cause errors, not easy to ensure specifications. In recent years, we have adopted “scriber” to delineate paddy field test plots, which is more convenient to implement and saves labor, reduces field trial errors and improves quality and progress. An experimental field about half an hour can be zoned, usually a day of labor can be scheduled 10-20 acres. The specific practice is: After the test field rake leveling and leveling, keep the mud is shallow, with the required specifications of “cross-checker”, vertical and horizontal cross-cut, according to the design of the test area length, width, Walkway, plug in each
