| 摘 要： | 为了明确不同储存方式和时间对秸秆沼液养分含量的影响，设置常温敞口和密闭储存2种方式，对不同储存时间的秸秆沼液中N、P、K及有机质含量进行了测定。结果表明：在沼液储存过程中有机质含量储存前后变化幅度较小，N、P、K总量明显降低，储存到50天时，N、P、K降幅达到80%~90%；2种储存方式中，密闭储存的沼液N、P、K降低少，因此从秸秆沼液肥用而言，密闭储存优于敞口储存。

Effects of Storage Methods and Time on Nutrients in Anaerobically Digested Slurry of Straw |
| |
| Abstract: | Exposure and confined for slurry storage at room temperature in N, P, K, organic matter content of nutrients were tested, The results showed that: slurry during storage, total nutrients deposited .Exposure and confined decreased, and stored up to 50 days, the total nutrients content decreased by nearly 80% ; Exposure storage and confined storage total phosphorus content in volatility is not the same,; Slurry during storage, total potassium content is generally lower than the store before, the two storage methods have individual peaks slightly higher than before storage; Biogas slurry during storage, exposure and confined two kinds of storage methods, organic matter content varies by less; Exposure and confined two kinds of storage methods comparison, storage period of 30 days, airtight storage of total nutrients, total potassium and organic matter content and storage than before, than the decline in Exposure storage is small, so within 30 days storage period, confined storage slurry than the overall exposure is good fertilizer; Biogas storage process, whether Exposure and confined storage total NPK were lower, save up to 50 days, total nitrogen, total phosphorus, total potassium content than before storage decreased by about 80% -90%. |
