冬型小麦品种于秋季播种时,不具备种子春化条件。正常生长的麦株,以幼苗状态通过春化阶段。然而,对在田间条件下的春化作用,目前尚无深入研究。 1982～1985年,于中国农科院作物所北圃场进行的小麦生态试验中,包括了山前、傲霜1号、特早2号、北京10号、临汾10号、郑州761、冀麦7号、白秃麦、东方红3号、新冬2号、泰山4号和肥麦等12个冬型小麦品种。在每个年度的分期播种试验中,都有3个秋播期。秋播第一期的播种日期在1982～1985年度中分别为9月10日、9月10日和9月7日;秋播第二期在3个年度中的播种日期都
Winter wheat varieties do not have the seed vernalization conditions when sown in autumn. Normal growth of wheat plants, seedlings through the vernalization phase. However, there is no further study on vernalization under field conditions. From 1982 to 1985, wheat ecological experiments conducted at the North Garden of Crops Institute of Chinese Academy of Agricultural Sciences included Pingshan, Aozhuang No.1, special early No.2, Beijing No.10, Linfen No.10, Zhengzhou 761, Jimai No.7, Baizhuimai, Dongfanghong No.3, Xin Dong No.2, Taishan No.4 and Feimai. There are three autumn sowing dates in each of the annual sowing trials. The sowing date of the first stage of autumn sowing was September 10, September 10 and September 7 respectively in 1982 ~ 1985; the sowing dates of the second stage of autumn sowing in three years
