摘要
为了研究提高糜子产量的途径,采用随机区组试验设计,设施肥处理和不施肥处理两组试验,对施肥对糜子出苗密度、产量及农艺性状影响进行研究。结果表明:施肥处理10个糜子品种出苗密度和出苗分蘖后单株密度分别低于不施肥处理7777.5丛/hm2、23888.6株/hm2。在本研究情况下,施肥处理产量小于不施肥产量467.7kg/hm2,密度对于提高单位面积产量具有至关重要的作用。不同糜子的穗长、株高、地上生物量、单穗粒重、千粒重、茎粗受施肥影响不同,有的增加,有的减小。施肥处理10个糜子品种的穗长、株高、地上生物量和不施肥处理之间差异均没有达到显著水平。部分品种施肥处理单穗粒重、千粒重、茎粗与不施肥处理之间达到了显著性差异,施肥处理茎粗均高于不施肥处理。糜子群体在一定的生存空间范围内,种群密度随时间的增长符合逻辑斯蒂模型,研究中施肥处理会造成糜子烧苗。
In order to improve the way of the proso millet production,randomized block design was used,two sets of tests fertilizer and no fertilizer treatment were studied,the density of proso millet emergence,yield and agronomic traits was determined.The results showed that,fertilization treatments 10 proso millet varieties emergence density and emergence of tillers per plant density were lower than without fertilization treatment 7777.5 tuft per hectare,23888.6 stock per hectare.In the case of this study,the fertilization treatments yield was less than no fertilizer production 467.7 kg/hm 2,density had a crucial role in improving the yield per unit area.The ear length,plant height,aboveground biomass,grain weight per spike,grain weight,stem diameter of proso millet had different appearance,some increased and some decreased.Fertilization treatments 10 proso millet varieties,panicle length,plant height,the difference between the aboveground biomass and fertilization treatments did not reach significant levels.Some varieties of fertilizer treatments kernel weight per spike,grain weight,stem diameter and fertilization treatments reached significant difference,the stem diameter of fertilization treatments were higher than no fertilizer.In a certain range of living space,the growth of population density of proso millet group in line with the logistic model followed time.Fertilization treatments would cause the burn seedlings of proso millet in this article.
