Embodiment 1
[0035] Example 1 Preparation of Rapeseed Pod Powder and Rapeseed Straw Section
[0036] After harvesting, rape stalks with rape pods (the rapeseed is Zheda 619, which is available in the market) are subjected to conventional drying, that is, after the rape is harvested, it is spread out in the sun for 3 to 7 days, or air-dried in the shade for 7 to 15 days. Rapeseeds were harvested from rape pods, and then the dried rape pods and rape stalks were placed in a 680-type hay cutter (Zhejiang Jinhua Shengshi Hardware Machinery Co., Ltd.) with apertures of 4mm and 8mm respectively for crushing, and the particle sizes were obtained respectively. Rapeseed pods of 0.5 cm in length and rapeseed straws of 3 cm in length and 0.5 cm in diameter; the rapeseed pods and rapeseed straws were further pulverized to 0.05 cm to obtain rapeseed pod powder and rape straw powder.
