Experimental Study on the Struvite Crystallization on Composting of Banana Stalk
Banana stalk is an agricultural waste, which is often discarded directly by farmers and further cause environmental pollution. To promote the recycling of banana stalk, magnesium chloride and potassium dihydrogen phosphate were added during the composting process of banana stalk to produce high-quality fertilizer which containing ammonium magnesium phosphate to achieve its resource utilization. The experiment was designed as two treatments, blank treatment (banana straw + EM composting bacteria), experimental treatment (banana straw + EM composting bacteria + magnesium chloride + potassium dihydrogen phosphate), and each treatment was three parallels. The results showed that the nutrient content of the experimental group was significantly higher than that of the blank group at the end of compost. The alkaline nutrient content of the blank treatment and the experimental treatment were 996.8 and 1974.0 mg/kg, respectively. The alkaline nitrogen content of the experimental treatment was about twice that of the blank treatment. The effective phosphorus content of the blank treatment and experimental treatment were 0.53 and 12.03 g/kg, accounting for 7.91% and 38.35% of the total phosphorus content, respectively. Adding magnesium chloride and potassium dihydrogen phosphate to banana stalk compost can effectively reduce the loss of nitrogen and phosphorus, increases the content of nitrogen and phosphorus in compost products, and effectively realizes the resource utilization of banana stalk.

水稻水肥调控是水稻获得高产的重要原因。为揭示间歇灌溉模式下不同缓释肥施肥水平对水稻生产影响,选取湖北省漳河灌区为研究区域,以水稻品种荃早优丝苗为试验材料,于2019年6-9月开展了淹水灌溉W1和间歇灌溉W2两种灌溉模式以及传统肥N1和缓释肥N2不同施肥水平[F(0.5)、F(0.75)、F(1)、F(1.25)、F(1.5)]互作条件下的水稻种植桶栽试验研究。结果表明,不同水肥处理对水稻株高、叶绿素SPAD终值的影响不显著,但在缓释肥条件下,植株株高、叶绿素SPAD值整体上在一定范围与施肥水平呈正相关,间歇灌溉模式下,N2F(1.5)处理与N2F(1)、N2F(0.75)处理差异显著,N2F(1.5)水平比N2F(1)、N2F(0.75)分别显著高出71%、91%。不同水肥处理对产量的影响显著,淹灌缓释肥W1N2F(1)处理产量最高可达18 170.29 kg/hm<sup>2</sup>,间歇灌溉传统肥W2N1F(1)处理次之,为17 826.86 kg/hm<sup>2</sup>。不同缓释肥施肥水平下淹灌模式产量比间歇灌溉平均高6.43%。传统肥条件下,间歇灌溉比淹灌产量高3.7%,缓释肥施肥水平对产量的影响最为显著。水稻种植施用缓释肥时,淹水灌溉模式更为适宜。

为了实现畜禽粪便的无害化处理及资源化利用,以新鲜牛粪和木屑作为堆料,采用微型试管堆肥法,模拟研究了好氧和厌氧2种堆肥方式下不同堆肥温度(38、50、70 ℃)对黄体酮、雄烯二酮、17β-雌二醇、雌酮4种天然类固醇激素降解的影响。结果表明,不同温度条件下4种激素在2种堆肥方式下的去除率介于67.6%~100%,其中50 ℃下的去除率为81.9%~100%。4种激素中,雌酮和雄烯二酮在好氧堆肥方式下的去除率优于厌氧堆肥。试验温度(38~70 ℃)对17β-雌二醇、黄体酮和雄烯二酮在牛粪堆肥中的降解影响很小,而在70 ℃的高温堆肥条件下,雌酮的降解受到抑制。在保证堆肥腐熟、杀死有害微生物的前提下,50 ℃下好氧堆肥效果最佳。
