Abstract
一种利用生物法生产糖醇有机肥料的方法，属于生物基因工程，微生物发酵，有机肥料技术领域。所述方法为：农业废物，在经过水解之后形成含木糖、阿拉伯糖、葡萄糖的混合液和固体料渣，混合液经微生物菌发酵后，转化为含木糖醇的液体，这个液体经固液分离之后，加入各种肥料中。所述农业废物为玉米秸秆，玉米芯，稻杆/壳，落叶。所述水解的温度为90‑100℃，固液比在1：3～10。本发明可以利用农业废物经过发酵转化为木糖醇，成本低，可以减少秸秆废物，提高农作物产量，作循环经济，保护黑土地。利用高科技工艺环保，无任何新的危化学品引入到肥料中，得到的肥料可申请有机肥料，用在高端的经济作物。可以促进各种元素吸收。
Description
技术领域
本发明属于生物基因工程，微生物发酵，有机肥料技术领域，具体涉及一种利用生物法生产糖醇有机肥料的方法。
背景技术
硅、钙、锌、铁、镁、铜、锰等是植物生长必需的元素等养分。目前，EDTA是螯合的主要化合物，分子大，植物不吸收，降解/污染土壤。
糖醇是多羟基化合物，是光合作用的初产物，属于功能性糖醇，糖醇与矿物质形成络合产物，糖醇复合体分子量低，可与表面活性剂，渗透剂等助剂结合，轻易的透过叶片的角质层进入到叶片的内部。糖醇是微量元素等养分的良好络合剂，可与很多营养物质形成稳定的复合体，同时，糖醇是目前唯一能携带矿质养分韧皮部进行快速传输的物质；而糖醇是植物韧皮汁液中的物质，无毒，对植物，人体，土壤无任何伤害。糖醇还是一种天然的润湿剂，具有保湿功能，能避免药液因在叶片讯速干燥而失效，延长叶片吸收时间。另外，糖醇还是天然的抗冻剂，增加植物的耐寒能力。
现有常规技术生产木糖醇，阿拉伯糖醇，甘露糖醇都是利用高压催化加氢还原对应的木糖，阿拉伯糖，果糖，工艺复杂，成本高，为主要用于食品及医药原料，无法用于肥料。
目前，市场需要一种低成本，有机地/天然的木糖醇，阿拉伯糖醇，甘露糖醇的生产技术。
发明内容
本发明的目的是为了解决目前生产糖醇的方法不安全，不环保，能耗大，有重金属杂质难去除，还消耗粮食等问题，提供一种利用生物法生产糖醇有机肥料的方法。
为实现上述目的，本发明采取的技术方案如下：
一种利用生物法生产糖醇有机肥料的方法，所述方法具体为：农业废物，在经过水解之后形成含木糖、阿拉伯糖、葡萄糖的混合液和固体料渣，混合液经微生物菌发酵后，转化为含木糖醇的液体，这个液体经固液分离之后，加入各种肥料中。
进一步地，所述固体料渣分离成木质素和纤维素，纤维素水解产生葡萄糖，经果糖异构酶转化之后产生高果糖浆，经生物发酵产生甘露醇，经固液分离后，可以直接做各种有机液体肥料的含甘露醇的基料，同时，分离出来的木质素经生物发酵后可以制成腐植酸肥料，做到农业废物的全部循环利用。
进一步地，所述农业废物为玉米秸秆，玉米芯，稻杆/壳，落叶。
进一步地，所述水解的温度为90-100℃，固液比在1：3～10。
进一步地，所述微生物菌为酵母菌，大肠杆菌或双歧杆菌中的一种或多种。
进一步地，所述发酵的温度30-40℃，pH在4-7之间。
进一步地，所述肥料为液体肥料或悬浮肥料。
进一步地，所述肥料中还加入N、P、K、钙、硅、铁、铝、锌、铜、钼或硼中的一种或多种。
本发明相对于现有技术的有益效果为：本发明可以利用农业废物经过发酵转化为木糖醇，成本低，可以减少秸秆废物，提高农作物产量，作循环经济，保护黑土地。利用高科技工艺环保，无任何新的危化学品引入到肥料中，得到的肥料可申请有机肥料，用在高端的经济作物。可以促进各种元素吸收。
具体实施方式
下面结合实施例对本发明的技术方案作进一步的说明，但并不局限于此，凡是对本发明技术方案进行修正或等同替换，而不脱离本发明技术方案的精神范围，均应涵盖再本发明的保护范围之中。
实施例1：
秸秆加入到水解池中1：5-10加水，通入蒸汽升温到80摄氏度，浸泡一天之后，固液分离，液体经放入发酵罐中在37℃、pH7.0加入菌种发酵，两天之后液体中的木糖转化为木糖醇，经固液分离之后，得到的液体可以做各种液体肥料的基料。
实施例2：
上例中得到的液体木糖醇可以做成各种液体肥料或者悬浮肥料，可以加入各种比例的N、P、K，以及钙、硅、铁、铝、锌、铜、钼、硼等各种元素，直接喷洒到叶面。
实施例3：
固体料渣分离成木质素和纤维素，纤维素水解产生葡萄糖，经果糖异构酶转化之后产生高果糖浆，经生物发酵产生甘露醇，经固液分离后，可以直接做各种有机液体肥料的含甘露醇的基料，同时，分离出来的木质素经生物发酵后可以制成腐植酸肥料，做到农业废物的全部循环利用。
