Timely cultivation of weeds, especially for arid areas. The first cultivation and sapling at the same time. Cultivated every 1-2 weeks later. Need to cultivate gold in the process of cultivating 3-4 times. Cultivation depth of 6-10 centimeters or so, the last one should be completed before flowering. Castor’s bracts are weak, lush foliage plants, vulnerable to wind and lodging, should be high soil, combined with cultivated. Second, topdressing, irrigation, brushing waterlogging. In the thin, underdeveloped base case, suitable for topdressing nitrogen fertilizer significantly increased yield, topdressing quantity, the number of times according to variety, soil fertility, base fertilizer
