cultivation techniques

Field management: after planting, weeding in intertillage in spring and winter every year 1 time. After each intertillage weeding, fertilization is combined. When the stems and vines grow to more than 30cm, it is necessary to set up a shed to lead the vines to the shelves. After the vines are put on the shelves, pay attention to pruning and branching, remove weak vines and overgrown vines, and branch too many axillary buds to promote nutrient concentration and facilitate fruit bearing. Artificial pollination should be carried out during flowering and fruiting period, and base fertilizer should be applied again.

Guagua begins to bear fruit 2 ~ 3 years after planting. Because of the long flowering period and inconsistent fruit maturity, it needs to be picked in batches in time. Then hang the fruit in a ventilated place to dry. Cut the fresh fruit of Cucurbita moschata with a knife, take out the seeds and dry them in the air to obtain Cucurbita moschata seeds, the skin is Cucurbita moschata skin, and dig out the roots and dry them in the air to obtain Trichosanthes.
