摘要
以两种不同比例施肥处理方式(T1:N_(420)P_(50)K_(100)、T2:N_(580)P_(190)K_(380)),分析鲜草产量及饲草营养价值。结果表明:施肥处理显著增加了钻石T黑麦草(Lolium multiflorum Lam.)鲜草产量(P<0.05),T1处理组鲜草总产量增加了1.99倍,T2处理组鲜草总产量增加了2.51倍,T2与T1处理相比增产17.25%。3次刈割中T1与T2处理组的CP、EE含量均显著增加(P<0.05),CF和P含量没有明显的变化规律,CA和Ca含量有增加的趋势,而NFE含量显著降低(P<0.05)。第一次刈割时T1、T2处理组粗蛋白含量比对照组分别增加38.0%和59.6%(P<0.05),第二次刈割时分别增加35.1%和54.1%(P<0.05),第三次刈割分别增加了37.5%和60.6%(P<0.05),而T2与T1相比,3次刈割中粗蛋白分别增加15.7%、14.0%和16.8%(P<0.05)。两种配方施肥处理都明显提高钻石T多花黑麦草鲜草产量和营养价值,且T2比T1效果更佳。
This study was carried out to determine the effect of two kinds of different proportion of fertilizing（T1：N420P50K100、T2：N580P190K380） on the yield and forage quality of Diamond T Italian ryegrass（Lolium multiflorum Lam.） .The results showed that fertilizer significantly improved the fresh forage yield of ryegrass（P〈0.05） , which were 1.99 times and 2.51 times higher than that of CK, respectively. The yield of fertilizer T2 increased by 17.25% compared to that of fertilizer T1. Fertilizer significantly increased the content of crude protein （CP） and ether extract（EE） （P〈0.05） , the content of crude fiber （CF） and P have no apparent variation, the content of crude ash （CA） and Ca were increased also, while decreased the content of nitrogen free extract （NFE） （P〈0.05） . When first mowing, the CP content of fertilizer T1 and T2 were increased by 38.0% and 59.6% compared to that of CK（P〈0.05） , the second time increased by 35.1% and 54.1% （P〈0.05） ,and the third time increased by 37.5% and 60.6% （P〈0.05） . The fertilizer T2 compared to that of fertilizer T1 in three times clipped,the content of CP increased by 15.7%,14.0%,16.8% respectively（P〈0.05） . Indicating that both formula fertilization treatment to improve diamond T ryegrass yield and the nutrition value, even T2 did better than T1.
