丽江坝区常年种植小麦六万多亩。高产试验田连续四年稳定在1600斤/亩以上,从而基本摸清了当家品种凤麦13号在丽江坝区生态条件下的生长发育特点及高产途径。鉴于全区40万亩小麦中,凤麦13号约占27万亩,丽江县的22万亩小麦中,凤麦13号占17万亩左右;特提出这个高产模式供坝区参考。一、凤麦十三号主要生育规律 1.分蘖成穗规律丽江坝区小麦分蘖消长特点是:一个盛期、一次高峰,越冬不停,缓慢消亡。适期播种的小麦,主茎2.5—3叶开始分蘖,五叶期为分蘖盛期(10月下旬播种的小麦至11月下旬初开始分蘖,直至12月中旬末,此时期内每亩日增长量为1—2万。主茎五叶期至茎蘖高峰期,因进入一月低温阶
Lijiang Dam perennial planting more than 60,000 acres of wheat. The high-yielding experimental field was stable at 1,600 kg / mu for four consecutive years, thus basically ascertaining the growth and development characteristics and high-yielding ways of the cultivar Fengmai No.13 in the ecological conditions of Lijiang Dam. In view of 40 acres of wheat in the region, Fengmai 13, accounting for about 27 acres, 220,000 acres of wheat in Lijiang County, Fengmai 13 accounted for about 17 acres; special proposed this high yield model for dam reference. First, Feng maize the main reproductive law on the 13th 1 tillering law ear tillering Lijiang dam tiller growth and decline is characterized by: a peak, a peak, the winter does not stop, slowly die. Wheat sown properly, with 2.5-3 leaves on the main stem tillering and the five-leaf stage tillering (wheat sowed in late October to early November late tillering until mid-December, with an increase per mu in this period The amount of 1-2 million. Main stem five leaf stage to the peak of stem tiller, due to enter the January low temperature order
