Trichosanthes kirilowii is a dioecious plant. It can be propagated by seeds, roots and layering. Seed reproduction is easy to degenerate, flowering and fruiting are late, and the ratio of female plants to male plants is difficult to control, so it is suitable for harvesting Trichosanthes kirilowii. In order to harvest Trichosanthes kirilowii, it is suitable to use root separation and layering propagation, which is easy to control the reproductive ratio of male and female plants. Production is mainly based on rooting propagation.

(1) Rooting and breeding In March and April in the north, from the end of 10 to the end of 12 in the south, 3-5-year-old and robust roots of Trichosanthes kirilowii were dug, and seeds with a diameter of 3-6 cm and a white and fresh cross section were selected and divided into small sections of 6- 10 cm. People who want to get Trichosanthes kirilowii should pay attention to digging more roots of female plants and less roots of male plants when digging roots. After digging, put them separately. Before planting, ditch should be dug according to the row spacing of 160 ~ 200 cm, with a width of 30 cm and a depth of 100 cm. Apply manure or compost in the ditch, every 667m, 1500 ~ 2500kg, mix well with the soil in the ditch, fill it up, and then water it. After the soil is fixed, dig a pit with a spacing of 30cm, spread the root segments in the pit, cover them with 4 ~ 5cm, compact them by hand, and then cultivate them with 10 ~ 65438+. About 20 days after planting, the soil on it will be removed during germination, and the seedlings will emerge about 1 month. Pay attention to the collocation of male and female plants when planting, and generally plant them in a reasonable and unified ratio of 5 ~ 10: 1. When Trichosanthes kirilowii blooms and bears fruit in the future, the yield can be greatly increased by artificial pollination.

(2) Layered propagation According to the characteristics that Trichosanthes kirilowii is prone to adventitious roots, when there is much rain and high temperature in summer and autumn, the robust stems and vines are pulled down and placed on the ground, and the soil is pressed between nodes. After the roots grow, they can be cut off to grow new stems and grow new plants, which can be transplanted in the next spring. If you want to bear more fruits, you should press more female plants and less male plants.

After emergence, in addition to general management, sheds should be set up to make the stems and vines climb and grow. Pruning and harrowing should be carried out during the flowering and fruiting period, so that the stems and vines will not be squeezed, with good ventilation and light transmission, and more fruits will be produced (see the part of garden cultivation).

Scaffolding, scaffolding or scaffolding can be used. Generally speaking, scaffolding is more productive than scaffolding. Scaffolding type should be rectangular shed with height of every 3 rows 180 cm, which can be erected according to local customs. The roof should be erected with horizontal bars and straight bars at an appropriate distance, and thick iron wires can be used instead. For the purpose of solid application, materials can be made of local materials.

Bracket type: three triangular brackets are inserted in the position of each plant, and the upper ends are tied together, and the upper ends of each row of brackets are tied together with cross bars. The height of the bracket is about 150 cm, and the material can be bamboo poles or branches. Scaffolding is relatively simple, with less materials, but the output is lower than scaffolding.
