1、 Soil:

Bitter hemp has strong adaptability to soil and can be planted on most plots, but it is better to choose plots with good drainage, fertile soil and convenient irrigation

2、 Illumination:

Bitter hemp likes wet environment and is not resistant to strong light. When the sun is soft, you can accept the light for a long time. When the light is strong, it is not conducive to the growth of bitter hemp and needs shading

3、 Temperature:

Bitter hemp is not resistant to cold and high temperature. Too low temperature is easy to cause plant freezing death. Too high temperature will affect growth. During cultivation, the temperature should be adjusted to 18-25 ℃

4、 Fertilization:

Bitter hemp has high requirements for fertilizer. In the early stage of cultivation, sufficient base fertilizer should be applied to ensure nutrients. Topdressing is required in the later stage, mainly nitrogen fertilizer

5、 Precautions:

1. Sowing: direct seeding or seedling transplanting can be selected for sowing. Generally, direct seeding is adopted in production, and hole sowing, drill sowing or on-demand sowing can be adopted in direct seeding. Due to the poor soil force on the top of seeds, the sowing depth should not be too deep

2. Diseases and insect pests: bitter hemp plant contains a kind of white milk, which is a bitter element, so its diseases and insect pests are very few. At this time, it only needs to spray some insecticides to control pests between summer and autumn
