1. Weeding When the seedling height is about 5 cm, the first weeding is performed and then once a month.
2, watering in time when irrigation is dry, mainly by ditches or bed surface irrigation, avoid large irrigation.
3, drainage with rain or torrential rain, when the trampoline water can be digging drainage ditch in time to rule out.
4. If autumn tube leaves no species, in the formation of buds in August, the buds will be taken to increase the weight of the root; after the plants withered in the end of autumn, the residual stems will be removed, and 2 cm thick circle dung or fine soil will be covered on the surface of the pods. Protect wintering buds safely for winter.
5. Keep seedlings that have been selected for more than 3 years. The fruit is pods, cracked, with 2000-4000 grains per fruit. When harvesting, the plants were cut and tied into small handles, placed in the room, and the seeds were cooked. After half a month, the small handles were inverted, and the seeds were lightly tapped. The seeds were selected twice with a 40-mesh sieve and a 60-mesh sieve. Place the seeds in a cloth bag, put it in a dry and ventilated place, or use it for sale.
6, pest control 1 spot blight: is the main disease of gentian, serious damage. The onset began in June and the onset was heavier in July-August. Control methods: starting from late May, spray wells water 50mg/kg, once every 10 days, even spray 3-5 times; or use thiophanate-methyl 600 times or double effect 300-500 Liquid spray, once every 7-10 days, 3-5 times in a row. Clear and burn diseased leaves and leaves to reduce the source of overwintering. 2 Brown spot: onset in June, severe from July to August, and the control methods are the same as above. 3 Underground pests: There are mainly roots such as cockroaches, cockroaches and wireworms. They can be applied to 1000 times zinc-phosphorus poisonous soil when they are used for soil preparation, hoeing or ploughing, or they can be sprayed and disinfected with 1,000 times zinc-phosphorus liquid.
7, harvesting and processing 1 Harvest: Spring and autumn harvest can be. Choose 3 years of plant, high yield and good quality. Do not injure the roots when harvesting, remove plants from the ground, dig underground roots, and remove dirt. 2 Processing: Wash the roots to dry or dry. When it is dry to 70%, the roots should be straightened, bundled, dried, or sun dried until dry but dry.
8, storage and storage will be processed goods packed in a cloth bag, placed in a ventilated and dry place, pay attention to moisture, flood and oil, smoke and other pollution.

In a hydroponic system, plants are placed in nutrient-enriched water. Mediums such as gravels, sand or vermiculite can also be used. Thus plants which are placed in the water absorb the nutrients very easly. When the nutrients from the water starts finishing , water is recycled or additional nutrients are added.
