岷山猫尾草和日本猫尾草品种对比试验

Comparative trial of Minshan timothy and Japanese timothy

试验比较了岷山猫尾草和日本猫尾草物候期、产草量、种子产量等生物学和植物学性状。结果表明,岷山猫尾草成熟期较日本猫尾草早3～5 d、生育期较日本猫尾草短3～4 d,属早熟品种;岷山猫尾草种植当年和第二年干草产量显著高于日本猫尾草,种植当年种子产量较日本猫尾草高58%,分蘖能力、越冬性能、营养价值均高于日本猫尾草。从品种适应性角度分析,岷山猫尾草更适应岷县闾井的自然环境和土壤条件。

Comparison was made between Minshan timothy （Pheum pratanse L）and Japanese timothy based on the biological and botanical characteristics such as phenological phase,yield of grass and seed.The results showed that：the mature period of Minshan timothy was 3 - 5 days earlier than Japanese timothy and growth period was 3 - 4 days shorter than Japanese timothy,it belonged to premature variety.The Minshan timothy hay yield were higher than Japanese timothy in the same year of the planting and the second year （P 〈 0.05）,and the seed yield increased by 58%,its tillering ability and overwintering ability were stronger and the nutritive value were higher than Japanese timothy.Analysis from the variety adaptability, Minshan timothy was more suitable for the natural environment and soil condition in Minxian Lvjing
