Land preparation and ridging
Choose the best sandy soil with convenient irrigation and drainage, apply 2000-3000 kilograms of farmyard manure per mu, spread it flat, and then plough deeply, without applying chemical fertilizer or pesticides. Row spacing 1 m, plant spacing of 0.6 m, planting per mu11/plant. Before planting,
Field planting
The planting period varies from place to place. Generally, it is planted in spring when the ground temperature of 5cm is stable at 14- 15℃, and it can be planted in protected land in advance.

After planting, when the height of the seedlings is 20 cm, water them to keep moisture, and combine weeding to cultivate the plants. If the amount of fertilizer before planting is insufficient, an appropriate amount of soil miscellaneous fertilizer should be applied at this stage to supplement it. Be careful not to use chemical fertilizers, pesticides and herbicides. Water the soil when it is dry and drain it in time after rain. When the stem grows to about 1m, tillers will be produced at the base. If the field is covered with vigorous growth, the tillers can be broken.
Harvest of fruit
Around 5438+00 in June, the bunches of flowers at the top of the plant began to wither, the leaves began to turn yellow, and the fruits began to be harvested. The south can stay underground for the winter and harvest and sell at any time. The north should be harvested before first frost and stored in the cellar, like sweet potatoes. Stem can be used as high-quality feed, leaves and flowers have high nutritional value, and can be dried to make tea or processed and reused. Generally, the fruit yield per plant is 3 kg, and the highest yield is 6544.
