自‘大穗型小麦——巴麦十八’一文在‘农业科技通讯’一九八二年第十期上发表后,全国各地二千九百多个单位和个人来函引种并陆续收到不少读者试种成功的喜讯。为了使读者更好地掌握巴麦十八的丰产栽培技术,现将应特别注意的几个问题略加说明。第一,巴麦十八是单穗生产潜力较大的穗重型品种,要特别注意发挥穗重优势夺高产。实践证明,田间平均单穗粒数可在五十至八十粒之间,单穗粒重二至三克左右。获得穗大粒多的首要一条是采用小群 Since the publication of ’Large-Spike Wheat-Baima 18’ in the 10th edition of ’Agricultural Science and Technology Newsletter’ in 1982, more than 2,900 units and individuals from all over the country have been introduced and received one after another Fewer readers try the good news of success. In order to give readers a better grasp of the high-yielding cultivation techniques of Baimai 18, a few issues that should be given special attention are briefly described. First, Baimai eighteen is a spike heavy variety with greater potential for producing single spike, paying special attention to taking advantage of spike weight and winning high yield. Practice has proved that the average number of grain per spike in the field can be between fifty and eighty grains, grain weight per spike two to three grams. Obtain a large grain of the most important one is the use of small groups
