Study on Introduction Test of Five Oat Varieties in Campa County of Xizang
摘要
Abstract
To screen oat varieties suitable for promotion and cultivation in high-altitude regions,an introduction and cultivation experiment was conducted in Campa County using Tianyan 2+,Hanma,Tianyan No.3,Beile and Jiayan No.2 as test varieties,based on previous experi-mental results.Key agronomic traits were measured,including plant height,stem diameter,flag leaf length,flag leaf width,fresh-to-dry ra-tio,leaf-to-stem ratio,and hay yield.The results showed that plant heights of the varieties ranged from 93.00 to 133.60 cm,with Tianyan No.3 exhibiting the highest height at 133.60 cm,which was extremely significantly higher(p<0.01)than those of Tianyan 2+and Hanma.Hanma had the largest stem diameter(6.53 mm),and extremely significantly thicker(p<0.01)than Tianyan 2+,Tianyan NO.3,and Jiay-an NO.2.Tianyan 2+had the longest flag leaf(40.29 cm),showing extremely significant superiority(p<0.01)over Hanma,Beile,and Jiayan NO.2.Both Tianyan 2+and Tianyan NO.3 had the widest flag leaves,which were significantly broader(p<0.05)than those of Han-ma and Jiayan No.2.Tianyan 2+displayed the highest fresh-to-dry ratio(5.81),which extremely significantly higher(p<0.01)than all oth-er varieties.Tianyan No.3 had the highest leaf-to-stem ratio(0.77),which was extremely significantly higher(p<0.01)than those of Jiayan No.2 and Tianyan 2+.Hay yields of the varieties rangedfrom 622.84 to 931.83 kg/667 m2.The highest yieldwas Hanma and thelowest was Jiayan No.2..Considering the current forage shortage in Campa County,Hanma,Tianyan 2+,and Beile showed outstanding performance in hay yield,and can be selected as the preferred varieties for the next phase of demonstration and promotion in the region.关键词
