1、 Soil

Rhubarb is suitable for cultivation in sandy soil with deep soil layer, fertile soil, loose soil and good drainage performance. Avoid continuous cropping, otherwise it will lead to variety degradation and slow growth

2、 Planting

Usually propagate with seeds. Seedling raising shall be carried out around the Qingming Festival, and the furrow shall be made by ploughing. The furrow shall be turned every 20 cm along the furrow. Then plant the seeds into the ditch, and then cover the soil with a hoe until they germinate

3、 Illumination

Sufficient light and illumination should be maintained throughout the year. Sufficient sunlight can promote its metabolism and increase its medicinal value. On the contrary, growth retardation and even withered and yellow growth may occur

4、 Fertilization

After the seeds are planted, enough base fertilizer shall be applied, and urea and fertilizer shall be applied in time during the growth period and after the harvest, which is about 10kg per mu. In winter, before the soil freezes, it should be watered with cold water and covered with a layer of ring fertilizer, so that the old roots can survive the winter safely

5、 Watering

A slightly humid environment is conducive to its health and is more resistant to drought. Keep the border moist before emergence, which can increase the emergence rate. Pay attention to drainage during rainy season to prevent disordered roots

6、 Precautions

1. The surrounding weeds should be removed in time to prevent its nutrients from being robbed

2. Attention should be paid to the timely loosening and disinfection of soil, and continuous cropping should be avoided
