| 摘 要： | 为了研究不同施肥量和不同施肥方式对饲用苎麻(Boehmeria nivea L.Gaud)产量和饲用品质的影响,采用2种复合肥施肥方式与2种尿素追肥方式,结合复合肥和尿素的不同施肥量,共设置8个施肥处理。结果表明:农艺性状方面,表现最好的为复合肥一次性基施(0.054 kg/m2)与尿素每收割一次追肥一次(0.006 kg/m2),其分株数42.00株/蔸、叶茎比2.04、干鲜比0.15;饲用产量方面,表现最好的是复合肥一次性基施(0.108 kg/m2)与尿素每收割一次追肥一次(0.0135 kg/m2),其产量鲜重达17.07 kg/m2,明显优于其他处理;饲用品质方面,复合肥一次性基施(0.108 kg/m2)与尿素每收割一次追肥一次(0.0135 kg/m2)、复合肥分2次施(0.054 kg/m2)与尿素每收割一次追肥一次(0.0135 kg/m2)、复合肥一次性基施(0.054 kg/m2)与尿素每收割一次追肥一次(0.006 kg/m2)3个处理的粗蛋白含量显著优于其他处理。本研究为提高饲用苎麻栽培管理技术提供了参考。

| Abstract: | In order to study the effects of different fertilizer levels and different fertilization methods on forage yield and forage quality of forage ramie, two ways of fertilizing compound fertilizer and two ways of topdressing urea were used. Through combination of different fertilizer levels of urea and compound fertilizer, eight fertilization treatments were set up. The results showed that when the application of compound fertilizer was conducted once as basal fertilizer at 0.054 kg/m2, and topdressing urea once every harvest at 0.006 kg/m2, agronomic traits were the best with the ramet number being 42.00 strains each stump, the ratio of leaf and stem being 2.04 and the ratio of dry and fresh weight being 0.15. When the application of compound fertilizer was conducted once as basal fertilizer at 0.108 kg/m2, and topdressing urea once every harvest at 0.0135 kg/m2, forage yield was 17.07 kg/m2, which was significantly better than that of other treatments. In terms of forage quality, content of crude protein in three treatments (compound fertilizer applied once as basal fertilizer at 0.108 kg/m2, and topdressing urea applied once every harvest at 0.0135 kg/m2; compound fertilizer applied twice as basal fertilizer at 0.054 kg/m2, and topdressing urea applied once every harvest at 0.0135 kg/m2; compound fertilizer applied once as basal fertilizer at 0.054 kg/m2, and topdressing urea applied once every harvest at 0.006 kg/m2) were significantly better than that in other treatments. This study provided a reference for improving forage ramie cultivation and management technologies. |
