Selection of land preparation and fertilization: choose loamy, sandy loam or humus loam with deep, well-drained, loose, fertile and sunny soil for the bed. Mu applied 2000 kilograms of farmyard fertilizer. The use of large ridge high bed technology, bed width 130 to 140 cm, length as needed, bed height 10 to 12 cm, bed spacing 30 cm.

Field management: Plowing and weeding. Seedling period should be diligent weeding and loosening the soil, after planting pay attention to the mid-plow weeding. If the weather is dry, to timely irrigation, can also be combined with fertilizer together.

Fertilizer: generally 3 times a year, combined with soil cultivation, to prevent collapse. The first fertilizer in May to apply clear animal and human fertilizer water, with about 1,000 kg per mu; the second in June when the seedling growth period into animal and human fertilizer, with about 1,250 kg per mu, you can also apply 5 kg of ammonium sulphate fertilizer per acre; the third fertilizer should be in August before the flowering of 1,000 to 1,500 kg of animal and human fertilizer per acre, with the addition of appropriate amount of grass ash and calcium superphosphate.

Flooding and drainage: in case of drought, we should water in time to keep the soil moist, and pay attention to timely drainage and flood prevention in the rainy season, so as not to rot the roots of the dead seedlings, reducing yield and quality.

De-bud: In July to August buds, for non-reserved land of Cangzhu plants should be removed in time buds, in order to facilitate the growth of the underground.

Harvesting and processing: the home grown Cangzhu needs to grow for 2 years before harvesting. Northern Cangzhu can be dug in spring and fall, but the quality of the dug after the fall to the following spring before the end of the seedling out of the ground is good.
