不同密度,垄上4行产量最高。其次是垄上3行、垄上2行。B区处理4,公顷保苗37.5万株,垄上4行,公顷产量3636.36kg,产量最高,其次是A区处理1,公顷保苗33万株,垄上4行,公顷产量3575.76kg,第三是C区处理7,公顷保苗42万株,垄上4行,公顷产量3530.30kg。但倒伏程度3级,倒伏率100%通过试验,播种方式最佳是垄上3行,密度33万一42万株/公顷 Different density, ridge on the 4 line output highest. Followed by the ridge on the 3 line, 2 on the ridge. Area B treatment 4, hectare Seedling 37.5 million, 4 on the ridge, 3636.36 kg hectare yield, the highest yield, followed by the A zone processing seedlings 350,000 hectares, ridge 4 lines, hectare yield 3575.76kg, the third is Area C treatment 7, 450,000 hectares of seedling seedlings, 4 on the ridge, hectare yield 3530.30kg. However, the degree of lodging 3, the lodging rate of 100% through the test, sowing the best way is ridge 3 lines, the density 330,442 plants / ha
