| 摘 要： | 红萍干萍、米糠等按C∶N比为25~30进行堆肥发酵,利用微生物分解红萍制作红萍有机肥。红萍发酵过程中温度迅速上升直至最高温度,然后开始下降;此时进行适时翻堆,当翻堆后温度又开始升高,然后再次下降;再次进行翻堆,温度又重复如此变化,但每次变化程度都有所不同,呈现不断加剧现象。pH值则呈不断上升趋势。不同营养成分发生了不同的变化,全N、P、K和速效P、K呈下降然后再上升趋势,速效N呈上升趋势,其含量得到了大大的提高。由此可见采用此方法可以制成优质的红萍有机肥。

| Abstract: | Dry Azolla and rice bran and other materials were mixed for compost fermentation in the ratio of 25 to 30 for C and N,using microorganism to resolve Azolla for its organic manures.In the fermenting process the temperature rose rapidly to the highest point and then fell.It was the time to turn the stack.Again the temperature rose after the turnover stack and then fell.When the stack was turned again,the temperature changed as before.But the degrees of temperature change were different;it changed more dramatic than before.The pH value rose constantly.Different nutrients changed differently.The values of total N,P,K and quick-acting P,K first fell and then rose.The value of quick-acting N rose constantly.It can be concluded that this method can be used to make good Azolla organic manure. |
