【摘要】 １９９３年引种皇草，对其不同生长年限、不同生育期和不同刈割期营养成分进行了观察和测定。结果表明：皇草在分蘖期营养成分含量高，但鲜草产量低，旺长期至拔节期株高１００ｃｍ时，鲜草产量最高，营养成分含量亦较高，是作为青饲料的最佳利用期；叶的营养成分含量高，茎次之；第１次刈割鲜草质量优于第２、３次刈割。更多还原

【Abstract】 Saccharum sinense Roxb was introduced in 1993 Its nutrient contents in different year, growth stage and mowing time was analysed The results showed as follows Nutrient contents is highest in the tillering stage, butthe freshyield is low Freshyield ishighest and nutrient contents also analogously high from vigorous growth stage to jointing stage at the plant height reaching about 100 cm This stage is best to use as green feed Nutrient contents of the leaf is higher than the stem The quality of fresh grass mowing first is better than the second or third更多还原
