摘要
通过对双低杂交油菜油研10号翻耕移栽、免耕移栽和免耕条播的试验,对产量、经济效益和植株性状进行比较研究,结果表明,免耕移栽平均产量183.11kg.667m-2,最高产量203.56kg.667m-2,免耕条播平均产量156.45kg.667m-2,最高产量169.78kg.667m-2,翻耕移栽与免耕移栽的产量差异不显著;免耕移栽比翻耕移栽用工投入平均减少108.08元.667m-2,纯经济收入平均增加93.95元.667m-2,差异达极显著水平,免耕条播比翻耕移栽用工投入平均减少137.78元.667m-2,纯经济收入平均增加69.71元.667m-2,差异达极显著水平,免耕移栽比免耕条播纯经济收入平均增加24.24元.667m-2,差异不显著;免耕移栽与翻耕移栽的植株性状较接近,差异不显著;甘蓝型黄籽双低杂交油菜油研10号免耕移栽适宜密度为6 000株.667m-2,免耕条播适宜播种量为0.35kg.667m-2,能获得高产,且纯经济收入较高。
Pair test desing was adopted to investigate the effect of ploughing transplanting, no-tillage transplanting and no-tillage drill seeding application on yields ,economic benefits and plant characters of Youyan10. The results showed that the average yield of ploughing transplanting was 189.00kg ·667m^-2 and highest yield reached to 206.22kg ·667m^-2. The average yield of no-tillage transplanting was 183.11kg·667m^-2 and highest yield reached to 203.56kg·667m^-2. The average yield of no-tillage drill seeding was 156.45kg·667m^-2 and highest yield reached to 169.78kg·667m^-2. There was nor significant difference between in yield of ploughing and no-tillage transplanting. The average of charge input was decreased by 108.08 yuan·667m^-2 in no-tillage transplanting than ploughing transplanting and average of net return was increased by 93.95 yuan ·667m^-2 in no-tillage transplanting than ploughing transplanting, its difference both reached the very significant level. The average of charge input was decreased by 137.78 yuan·667m^-2 in no-tillage drill seeding than ploughing transplanting and average of net return was increased by 69.71 yuan·667m^-2 in no-tillage drill seeding than ploughing transplanting, its difference both reached the very significant level. The average of net return was increased by 24.24 yuan·667m^-2 in no-tillage transplanting than no-tillage drill seeding and no significant difference. There was no significant difference between in plant character of no-tillage and ploughing transplanting, youyan10 the suitable density of no-tillage transplanting was 6 000 plants ·667m^-2 and suitable sowing rates of no-tillage drill seeding was 0.35kg·667m^-2 ,the both could obtain highest yield and better net return.
