2. cultivation and management

2.1 seed treatment

Select large, plump and fresh seeds, store them properly in cool and dry containers after natural air-drying without exposure, and pay attention to moth prevention. In order to improve the germination rate of seeds, seeds can be directly sown after drying in the shade. soak seeds in potassium permanganate solution with concentration of 0. 5% for disinfection for 2h before sow, putting into warm water for germination for 24h, taking out seed after absorbing water and swelling, and placing on soaked absorbent paper or gauze for drying. Sowing can be carried out when the germination rate exceeds 10%.

2.2 seeding technology

Depending on the number of seeds, bed sowing or pot sowing can be selected. Requirements seedbed dry, flat, leeward, sunny, loose fertile soil. Available sand seeding, both water and a certain amount of water storage capacity. The thickness of soil cover is about 0.5cm. After sowing seedbed to keep moist, do not suddenly dry suddenly wet or too dry too wet. After germination, seeds need to be removed from the mulch, so that they gradually see the light, and after adaptation, they can be fully exposed to sunlight. If the seedlings are too dense, they should be pulled out between rows, and the thin seedlings that are too dense should be pulled out so that the remaining seedlings can fully absorb sunlight. Water immediately after interplanting, so that the loose seedlings can contact the soil. About 2 true leaves can grow in about 10 days.

2.3 transplantation

When the seedlings grow 3-4 true leaves, they can be transplanted and replaced. It is advisable to select sandy loam rich in humus.

Allow the soil to dry out before each pot change, then gently tap the pot wall around, loosen and carefully remove the plant with soil. Do not move the original soil ball before changing the big pot, so as not to hurt the roots. After planting, irrigation should be sufficient. After the first irrigation, before the new roots are born, too much irrigation should not be allowed, otherwise the roots will rot easily. The root system of seedlings is small and the transpiration of the aboveground part is large. After transplantation, strong sunlight should be blocked for several days to facilitate recovery growth.

2.4 training and pruning

Ornamental eggplant plant height about 15CM when the top, so that it grows branches, branches grow to about 10CM again top. Generally topping 3-4 times, promote multi-branching, plant shape short and strong, can form a high 40- 50CM spherical plant, so very beautiful after hanging fruit. After the leaves are long and dense, they must be picked off, and the large and yellow old leaves must be removed to facilitate ventilation and enhance illumination, so that the leaves are thin and thick. When picking leaves, excessive long branches, over-dense branches, withered branches and diseased branches should also be cut off to make their plant shape beautiful.

3. conclusion

After high-yield and high-quality cultivation of African red nightshade, a good and potential market development prospect has been cast. The utility model has the characteristics of low operation cost, simple operation technology and easy learning, meets the requirements of today's environmental beautification, good market sales prospect and can create considerable economic value. African red nightshade small red fruit for cut flowers with material is also quite a hole, refreshing.
