After the emergence of the pumpkin, use a deep loose ruler to loosen the depth in the furrows by 25-30cm. Play the role of cold, warming, loose soil, weeding, water storage, security, prevent disease, reduce wind erosion, water erosion. When it grows to 3 to 4 leaves, it will be cultivated by cultivators.
CENTERING (pickling) The squash grows to a period of four-leaf-leaf. Manually setting the core (also called topping) in the morning at 5 to 10 o'clock and at 3 to 7 o'clock in the afternoon, the growing point of the pumpkin is manually removed. To remove completely and not hurt the fourth leaf. Try to avoid the high temperature period at noon so as to prevent the pumpkin from losing too much water and affecting growth. The core setting time is from June 10 to June 25. After vines and vines are set, the white squash seeds grow from the first, second, third and fourth leafhoppers, destroying the vines on the first and second quarters. The earlier the better, prevent one or two vines. Excessive influence of three or four vines. Leave the third and fourth quarters of the vines growing. When the length of the three or four vines is 35 to 50 cm in length, artificial vines (cis vines) are introduced, and the two vines are led to both sides of the main planting ridge, and are led 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.
After the growth of the artificial pollination melon, the first vine spreads to the seventh quarter. When the four vines grow to the ninth quarter, the first female flower is generally produced. After the female petal is expanded, the pistil stigma can be used to receive pollen (stamen pollen). Fertilization. At this time, every day from 5 to 9 am, 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 to 3 pistils. Be sure to choose between 5 and 9 o'clock in the morning, because this is the period when the stamens and stamens grow most vigorously, with high insemination rates and strong vitality. Each pistil receives pollen continuously for two days and can achieve 100% fertility.
After artificial pollination, the petals began to wilted and closed, proving that they had been 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.
Remove two sub-growth points each sub-wing nectar, leave four leaves in the melon, and then remove the melon top growth point, to ensure adequate moisture, nutrient supply without loss.
After killing Sun Man, when the two vines are picked up, they will grow many sun vines. At this time, they must observe the fields for a long time and find that all the sun vines are born and immediately destroyed. Don't injure the vine when removing the vine. General use scissors to cut vines better. Sun Man must not be allowed to grow too long. It will seriously affect the yield of pumpkins, and it will also result in fruit drop.
锄 æ‚ æ‚ Weeds Currently, there are not many chemical herbicides for pumpkins, and there are fewer agents for broad-leaved weeds. After application, they will form more or less critical parts. We recommend that we not use broad-leaf herbicides and use manual weeding.
