First, intertillage weeding
Trichosanthes kirilowii is usually planted when the seedlings grow to about 10 to 15 cm. After planting, we should check the growth of seedlings in the field and replenish them in time. When the seedlings of Trichosanthes kirilowii grow to about 20 cm, it is necessary to carry out the first intertillage weeding after planting. At this time, shallow tillage is generally used to weed, so as not to hurt the root system of Trichosanthes kirilowii seedlings. In the later stage, intertillage should be carried out according to the specific growth of Trichosanthes kirilowii seedlings. Generally, after repeated watering or continuous rainfall, intertillage should be carried out in time to avoid reducing hardening. However, after the late fruit, try to reduce the number of intertillage.
Second, fertilizer and water management.
Seedlings are usually planted in rainy days. In this case, water is not needed, but if the planting weather is dry, water is needed. The first topdressing is usually when the seedlings of Trichosanthes kirilowii grow to about 40 to 50 cm, and the quick-acting fertilizer is the main fertilizer. It is best to choose topdressing in rainy days, so as to better absorb nutrients. In the growth period of Trichosanthes kirilowii, topdressing is generally carried out in three times, and the types of fertilizers used are the same as the first topdressing, and the later fertilization is appropriate fertilization after each harvest. Generally, water should be used when fertilizing, and the second is to adjust the amount of water reasonably according to the different growth periods of Trichosanthes kirilowii.
Third, build scaffolding
In order to improve the yield of Trichosanthes kirilowii, reduce the occurrence of pests and diseases, and facilitate the later management, when the seedlings of Trichosanthes kirilowii grow to about 50 cm, it is necessary to build a greenhouse. The height of the scaffolding is generally about one meter eight to two meters. Fix the scaffold, bury it about 30 cm deep, and then connect it with thick rope at the top of the scaffold, and drag the Trichosanthes kirilowii seedlings to the scaffold to crawl and grow, so as to control the permeability of the field.
Fourth, pruning and branching
When the Trichosanthes kirilowii seedlings are pulled to the bracket, the redundant stems and leaves can be removed, and 2-3 robust branches can be kept. When the main stem vines grow to about four or five meters, wipe off the terminal buds of the main stem vines to promote the growth of branches, and then keep the secondary stem vines, the tertiary stem vines and the prepared branches in the previous way. At the same time, when pruning branches and leaves, the stems and vines should be arranged neatly to avoid overlapping and squeezing, so as to ensure the permeability of the field and concentrate on supplying nutrients.
Verb (abbreviation for verb) artificial insemination
The natural pollination rate of Trichosanthes kirilowii is relatively low, so the yield of wild Trichosanthes kirilowii is basically unstable and relatively low. Then according to this characteristic, we need artificial pollination in field management, so as to improve the yield and quality of Trichosanthes kirilowii. Generally, the pollen of male flowers can be painted on the stigma of female flowers with brushes or feathers, so that pollination can be sufficient and the yield can be guaranteed.
