| 摘 要： | 为进一步探索三江平原白浆土地区小麦高产途径，采用垄作和垄上多条精量播种相结合的栽培模式，提高小麦单产。结果表明：７０ｃｍ垄距、垄上４条播比对照１５ｃｍ单条播增产２６％；采用７０ｃｍ垄宽、垄上４条播的最佳播种密度为５２５～６００万株／ｈｍ２；将本年度结果与前两年结果进行全面分析拟合，其结果三年完全一致。

| Abstract: | In order to research ways of wheet high proluction in Albisols areas of Sanjiang plain, the usa of caltural model of riage culture combined with four drills with exact seed raises wheet production. The results showd that: 1.70 CM ridge wide and four drills with exact seed raised production 26% than 15 CM one drill. 2. the best sowing deasity of 70CM ridge wide and four drills exact seed is 5250000-6000000/ha. 3.The result of this year and last two years was analysed and imitated,the result is consistant. |
