分别利用沼液和尿素进行混播草地施肥试验，结果表明，混播草地中牧草的产量受到氮肥种类、施氮水平和环境温度的限制。在环境温度较高时，施入尿素含量越高，牧草生长速率较快，产量越高；而当秋季温度较低时，豆科牧草长势旺盛，因此氮肥对混播牧草产量的影响相对较小；同时，由于沼液对土壤的培肥作用较好，以大量施入沼液的牧草长势较好，产量较高。

The experiment on using different N of biogas slurry and urea to apply mixture pasture was conducted. The results showed that the yields of mixture pasture were affected by forms of fertilizer, different equivalent N and controlled by environmental temperature. When environmental temperature was high, the yields of mixture pasture and the rate of grass growth were higher by fertilized the highest amount of urea. When the temperature was lower on the fall, forage legumes was growing stronger, so the effect of N fertilization on forage yield of mixed pasture was relatively small. The forage yield was higher with the larger biogas slurry application amount.
