The cultivation of high quality Panax notoginseng must be based on farm manure, supplemented by a small amount of compound fertilizer, and the ratio of nitrogen, phosphorus and potassium should be 2 ∶ 1 ∶ 3. Excessive application of nitrogen fertilizer will lead to the decline of Panax notoginseng quality. The base fertilizer should be 2500-4000 kg / mu farm manure, and the topdressing should be from June to September. The foliar fertilizer is Yang Kangsheng fertilizer, Huimanfeng active biological fertilizer, potassium dihydrogen phosphate and urea.

During the period of field management, fertilization is applied at least 5 times a year, mostly 8 times, about once every 2 months, and the first time is about 150 jin of plant ash and 500 jin of turf ash, when the emergence of seedlings reaches 70%. The second time around April, when spreading leaves, 200 jin of mixed fertilizer was applied per mu (30 jin of cow bone powder and 50 jin of calcium superphosphate, which was applied after fermentation.) The third time was in May, when 200 jin of mixed fertilizer was applied. The fourth time in July, green manure was applied (chopped green manure for fermentation), and the fermented green manure was evenly distributed on the border. Panax notoginseng can also be used to raise seedlings with urea at seedling stage, a small amount for many times, and phosphorus and potassium fertilizer should be applied at flowering and fruiting stage. Fertilization at least 4 to 5 times a year, about every 1 to 2 months topdressing, each time about 30 kg per mu, the method is artificial sprinkling, fertilization, some fertilizers fall on the leaves of Panax notoginseng, will burn leaves, so, in fertilization, to hit the leaves with sticks, so that fertilizer fell to the ground, that is to avoid burns leaves, but also increased the utilization rate of fertilizer.

In case of drought, it should be watered in the evening.
