孟加拉国的秸秆切割机 is badly needed, for crushed straw can be used for many fields. However, there are many problems about dealing with straw in Bangladesh.
不完整的秸秆供应系统
孟加拉国的秸秆收集缺乏专业的机械和服务机制，政府尚未建立稳定的价格体系。在这种情况下，农民的积极性不高。影响秸秆收集和存储的因素很多，例如天气等不确定因素的影响，以及建设存储空间成本的增加。这些都使得秸秆资源的统一收集和调配变得困难。
未成熟的秸秆收集技术
Straw cutting machine in Bangladesh is rear-mounted with small size and low efficiency, and it is just suitable for dry land. So, it is difficult for straw cutter machine to work in paddy fields. When working, there are such malfunctions as entanglement, clogging of working parts, which makes it impossible to collect relatively high and thick straw such as corn straw and sorghum straw.
The tractor-driven straw cutting machine in Bangladesh is not easy to turn, and is suitable for fields with large space. Moreover, the straw cutting machine and straw baling machine work separately, increasing labor intensity.
湿存储机制不明确
在存储作物秸秆时，需要考虑存储的稳定性，以尽可能减少损失。当秸秆的含水量超过50%时，通常采用湿存储和封闭环境存储（如地窖）。
然而，湿存储增加了运输和处理的成本。此外，影响湿存储的条件和因素不确定，需要在孟加拉国进行深入研究。
目前，可以通过快速发酵产生乳酸菌，降低pH值并消耗氧气，形成厌氧环境。这样可以在存储期间保持秸秆的水分含量、pH值和氧气浓度在最佳状态。
我的结论与建议
1. It is recommended to reach an agreement with the local farmers to store straw jointly.
2. By examining the distribution of farmland, selecting appropriate locations to establish large straw acquisition points.
3. Develop combined straw cutting machine in Bangladesh for small farmland areas with soft soil and much mud.
4.Seek effective and economical storage methods for the straw that is easy firing and mildew during storage time.
