在南斯拉夫,有人用5个小麦品种进行了密度和距离的研究。每个品种设不同播量的三个处理,分别是每平方米300粒、500粒和700粒种子,所得株数少于实际播的种子数,所占比例分别为12.7%、14.4%和15.9%。除行距最宽播量最大的这一处理减产3%外,行距6厘米、12厘米、18厘米和25厘米的处理几乎对产量无影响。最小播量的处理有效分蘖数高于播量适中的处理25%,并且行距60厘米、小播量时,有效分蘖更强。除品种 Sremioa-Er 外,其它品 In Yugoslavia, studies were conducted on the density and distance of five wheat cultivars. The three treatments with different sowing rates for each variety were 300, 500 and 700 seeds per square meter, respectively. The number of seeds obtained was less than that of the actual sowing seeds, accounting for 12.7%, 14.4% and 15.9% respectively, . In addition to the 3% reduction of the line with the widest seeding line, the treatments of 6, 12, 18 and 25 cm have almost no effect on the yield. The minimum effective sowing number of effective tillers is higher than the sowing rate of 25%, and the spacing of 60 cm, sowing, the effective tiller stronger. In addition to varieties Sremioa-Er, other products
