After that, it is appropriate to apply less fertilizer. Generally, thin fertilizer can be applied once every 20 days. However, before flowering, fertilizer can be applied once every 7-10 days to promote flowering. Fertilization must be appropriate, especially excessive nitrogen fertilizer, will cause only long leaves do not bloom consequences, thus affecting the viewing effect.

5, pruning: in order to make the golden lotus leaves fat flower beauty, but also must use thin bamboo to set up a bracket, the vine stem evenly tied to the shelf, and make the leaf surface as far as possible in one direction, before the shelf to pick the heart, leaving the main stem and thick side stem, in order to promote its germination more branches, to achieve the purpose of leaf luxuriant flower.

6. Disease and pest control: The most common diseases of Trollius chinensis are leaf spot disease, wilt disease and virus disease. The control method can be sprayed with 500 times solution of 50% Tobucine WP. Usually maintenance should pay attention to ventilation, disinfection, timely drainage, in case of rotten roots. Insect pests mainly include whitefly moth, whitefly, red spider, mole cricket, insect, etc. In case of insect pests, pollution-free pesticides such as pirachlorine, buprofezin and dimekill should be applied in time to avoid affecting the growth of golden lotus flower.

3) topdressing: trollius should be topdressing nitrogen fertilizer after seedling recovery. When transplanting seedlings in the same year, human and animal feces and urine should be diluted 1~2 times. Ammonium phosphate granular fertilizer can be applied from June to July, and organic fertilizer should be applied before freezing in winter, applying 1500~2000kg per 667 square meters.

When transplanting, 3~5 seedlings should be used as a pier, and 1~3 leaves at the bottom should be removed at the same time to reduce nutrient consumption. Transplantation depth should be shallow not deep, and timely watering.
