摘要
对青海燕麦 4 4 4进行了不同播种量的比较试验 ,结果表明 :播种量对青海燕麦 4 4 4的物候期、产草量、生长速度、生长速率均产生明显的影响。试验区内燕麦 4 4 4的最佳播种量为 150kg/hm2 。
The comparative experiment on different levels of seeding quantity of oat (No.444 Qinghai) was carried out at Sanjiaocheng. Sheep Station in Qinghai province in 1997. A random block design with 3 replicates was used. The results of variance analysis and LSR test showed that different levels of seeding quantity had significant effects on the phenophase, dry matter yield, growth rate and biomass growth rate of oat. The optimum seeding quantity of No. 444 oat was 150 kg/hm 2 .
