摘要：

本发明公开了一种用棉花秸秆制备生物炭基肥料的方法,包括以下步骤:步骤1,利用棉花秸秆制备棉花秸秆生物炭;步骤2,粉碎石膏,膨润土和棉花秸秆生物炭,石膏和膨润土过100目筛,棉花秸秆生物炭过40目筛;步骤3,将16～19重量份磷酸铵,7～9重量份尿素,7～9重量份硫酸钾,1～2重量份硫酸锌,1～2重量份硼酸,7～9重量份硝基腐植酸,30～40重量份棉花秸秆生物炭,7～12重量份石膏和7～12重量份膨润土混合到一起并搅拌均匀,获得肥料混合物;步骤4,对所述肥料混合物首先用转鼓造粒机进行初步造粒,然后用圆盘造粒机进行整型造粒,获得肥料颗粒;步骤5,用干燥机对肥料颗粒进行干燥处理,得到生物炭基肥料. The present invention discloses a method for the preparation of biological cotton stalk carbon-based fertilizers, comprising the following steps: Step 1, the use of cotton, cotton stalk of straw preparation biochar; step 2, crushed gypsum, bentonite and cotton stalks biochar, gypsum and bentonite over 100 mesh sieve, cotton stalk biochar 40 mesh sieve; step 3, 16 to 19 parts by weight of ammonium phosphate, 7-9 parts by weight of urea, 7-9 parts by weight of potassium sulfate, 1 to 2 parts by weight of zinc sulfate, 1 ~ 2 parts by weight of boric acid, 7-9 parts by weight of NHA, 30 to 40 parts by weight of cotton stalk biochar, 7 to 12 parts by weight of gypsum and from 7 to 12 parts by weight of bentonite uniformly mixed together and stirred to obtain a fertilizer mixture; step 4, for the fertilizer mixture first with a preliminary granulation drum granulator, disc granulator and then granulated be integral to obtain the fertilizer particles; Step 5, with drier fertilizer granules dried to give biochar-based fertilizers.
