Castor seed harvesting should master the following harvesting methods. A look: First of all, it depends on whether the castor bean is mature or not. The roots of the castor bean are mature and the kernels are full, and they can be harvested after maturity. The criteria for judging the maturity of castor beans during harvesting were as follows: Mature castor bean shells and burrs dried, changed from green to purple-brown, and the hands touched and the bottom leaves turned yellow or dry. Second pick: pick castor seeds should be appropriate in the afternoon. The ramie stems are held in one hand, and the castor seeds are smashed in one hand. When it is light, do not tear off the cortex of the stem of the castor plant. This will damage the stem of the castor and affect the growth of the upper castor bean. Harvesting takes a look at maturity. Custody: After harvesting castor beans, it is not appropriate to amplify the heap and it is not appropriate to store it for too long. After harvesting, the castor bean must be dried in time and spread a little thin. It must be turned frequently to make the castor bean dry quickly. In case of rain, pile up in time and cover it with a rag. After drying, pack it in a bag and store it in a dry place. In the case of not affecting the farm work, promptly threshing after drying, shelling machine threshing or artificial threshing.
