For black-skinned chewing cane kept as seed cane, in winter it is advisable to apply a heavy dose of potassium fertilizer, so as to raise the plant's nutritional level and the potassium content of the part kept as seed cane. Only in this way can the cold resistance and overwintering ability of the seed cane be strengthened, making the cane buds plump, so that after next spring they sprout early, sprout quickly, sprout evenly, with strong cane seedlings, strong disease resistance and fast growth, making it easy to obtain high yield and excellent quality.
Specific method: in winter, apply potassium fertilizer once to the roots of black-skinned chewing cane. Generally, 50-60 kg of potassium nitrate or potassium sulfate can be applied per mu, mixed with 80-100 times its volume of clean water, and then evenly drenched onto the soil around the roots of the black-skinned chewing cane. At the same time, every 10-15 days spray once on the leaves a 0.3%-0.5% potassium dihydrogen phosphate aqueous solution, or a 300-500 times diluted potassium nitrate aqueous solution, spraying continuously 3-5 times, evenly wetting all stems and leaves, until water droplets begin to drip down. This method can obviously increase the potassium content of each black-skinned chewing cane plant, making the seed cane thick and strong with plump buds, and obviously improving the quality of the seed cane.
