[Ditch and furrows and cultivators]
After the emergence of the pumpkin, use a deep loose ruler to loosen it 25-30cm deep in the furrows. Play the role of cold, warming, loose soil, weeding, water storage, security, prevent disease, reduce wind erosion, water erosion. When it grows to 3-4 leaves, it will be cultivated by cultivators.
[Fixed core]
The squash grows to four compound leaves, and artificially set the core (also called topping) in the morning 5-10, in the afternoon 3-7, artificially remove the growing point of the pumpkin. To remove completely and not hurt the fourth leaf.
[Branches and collar vines]
After the core is inoculated, the white gourd seeds grow from the first, second, third and fourth sections of the leafhopper, destroying the seed vines on the first and second sections, and the earlier the better, preventing the vines of the first and second seeds from growing too much. Third, four son vines. Leave the third and fourth quarters of the vines growing. When the length of the third and fourth vines reaches 35-50cm, artificial vines (cis vines) are introduced to guide the two vines to both sides of the main ridge, leading along the direction of 20-30 degrees of the ridge. The direction of the vines should be the same among the strains so as not to cross each other and affect the growth.
Artificial Pollination
After the vine grows, the first vine grows to the seventh quarter. When the four vines grow to the ninth quarter, they usually produce the first female flower. After the female petal is unfolded, the pistil stigma can receive fertilization pollen (stamen pollen). At this time from 5 to 9 am every day, the newly opened male flower core (the stamen's pollen stick) is gently removed from the field and gently rubbed against the pistil to adhere the pollen to the pistil stigma. Each stamen can only adhere to 2-3 pistils. Must be selected in the morning of 5-9 every day, because this is the most vigorous growth period of stamens, high insemination rate, strong vitality. Each pistil receives pollen continuously for two days and can achieve 100% fertility.
ã€Pressing vines】
After artificial pollination by female flowers, the petals began to wil to close and prove to be pregnant. A small pile of soil was pressed on the front section of each melon and the vines were brought into close contact with the ground, and secondary roots were grown to supply the seeds with water and nutrients. When vines are pressed, it is best to leave the melons on top of ridges or pile up small mounds and leave the melons on them to prevent the excessive rain from causing disease.
ã€Remove two vines growing point】
After each vine spreads melons, leave four leaves behind the melon, and then remove the top growing point of the melon to ensure that there is sufficient water supply and nutrient supply without loss.
ã€é”„Net Weeds】
At present, there are not many chemical herbicides for pumpkins, and there are fewer agents for broad-leaved weeds, and more or less of them will form the key. It is recommended not to use broad-leaf herbicides and artificial weeding.
