不同类型肥料对“藏青2000”农艺性状及产量的影响

Effects of different types of fertilizers on the agronomic traits and yield of barley 2000

在尿素、微生物肥料措施下,研究不同类型肥料对"藏青2000"不同生育期农艺性状及产量的影响。结果表明:整体而言,对根系的根长、根数的影响,尿素>微生物肥料;对根系的根重的影响,尿素<微生物肥料。对农艺性状各指标(株高、叶片重、叶鞘重、穗粒重)均表现为尿素>微生物肥料。对产量及各构成因素均表现为尿素>微生物肥料。由此判定,尿素对"藏青2000"农艺性状及产量的效果好于微生物肥料。

in urea, measures of microbial fertilizer, effects of different types of fertilizers on barley 2000 at different growth stages of agronomic traits and yield. The results show that over- all, root root length, root number, urea 〉 microbial fertilizer; root root weight, urea 〈 micro- bial fertilizer. The agronomic traits of each index （plant height, leaf weight, weight of leaf sheath, grain weight per spike） showed urea 〉 microbial fertilizer. The yield and components showed urea 〉 microbial fertilizer. Thus determine, urea on barley 2000 agronomic traits and yield good effect on microbial fertilizer.
