| 摘 要： | 以不同燕麦品种、施尿素量、行距和播量在青海果洛州达日县进行正交试验表明,各因素对燕麦株高的影响均极显著,燕麦生长期间各处理生长速率的峰值分别出现在分蘖盛期、拔节盛期和孕穗盛期,最快生长期出现在7月14日至23日拔节盛期。获得最高产草量的最适行距、施尿素量和播种量分别为13.2 cm、250kg/hm2和250 kg/hm2。燕麦在试验地区生殖生长期不足,单蘖穗重占单蘖重的比例较低,而单蘖茎重则成为单蘖重的主要结构成分。与单蘖重关系最显著的是单蘖茎重,其次为单蘖叶重和秆径,而单蘖穗重与之相关不显著。

| Abstract: | To use orthogonal design, in Daer county of Qinghai province, according to oat species, the-numder of fertilizing urea, row spacing, the number of sowing seeds, have studied effects of every factor on oat production performance. The result showed that every factor had significant effects on plant height, and the growth ratio of oat for every treatment was maximum in tilling period, shooting period, booting period respectively. The maximum growing period was from the 14thto23rd of July. The best proper row spacing, quantity of fertilizing and sowing seeds to gain thehighest yield were 13.2 cm, 250 kg and 250 kg respectively. In this region, procreating period was not enough, and the ratio of a spike weight amounting to a tiller was low, but the ratio of a stem was very big. There was significant different between dry weight of a tiller and stem weight of a tiller, leaves weight of a tiller and stem diameter, but it was not significant with spike weight of a tiller. |
