播种量和施肥对丘陵红壤区裸燕麦产量和主要性状的影响

在江西丘陵红壤区研究了不同播种量和施肥对裸燕麦品种白燕8号和坝莜6号产量及主要性状的影响。结果表明:这两个品种的产量差异不显著;不同播种量和施肥对燕麦产量均有极显著的影响;白燕8号和坝莜6号在播种量75 kg/hm2、基肥施复合肥525 kg/hm2、追肥施尿素和氯化钾各60 kg/hm2的条件下可以获得最高的产量。

Effects of Seeding Rate and Fertilization on Yield and Main Traits of Naked Oat in Hilly Red Soil Area

A field experiment with multi-factor(variety,seeding rate,and fertilization) design was conducted to study the influences of seeding rate and fertilization on the yield and main traits of naked oat in hilly red soil area of Jiangxi.The naked oat varieties Baiyan No.8 and Bayou No.6 were taken as the test materials.The results indicated that there was no significant difference in the yield between these two varieties,while both seeding rate and fertilization very significantly affected the oat yield.The conditions for the highest yield of Baiyan No.8 and Bayou No.6 was obtained as follows: seeding rate 75 kg/hm2,compound fertilizer 525 kg/hm2 as base fertilizer,and 60 kg/hm2 urea and 60 kg/hm2 potassium chloride as top dressing.
