Pumpkin Field Management of Giant Pumpkin:



    1, do a good job of melon vines fixed and windproof.



    In the spring, the north wind is big, and there are often hurricanes in the south. The giant pumpkin leaves are big and the stems are brittle and easy to fold. In order to avoid the wind blows over by the wind, the first thing is to use the small hoe to loosen the soil under the vines and make it with iron wire." U" shape, the melons are fixed on the surface of the earth. After the roots of the melons are rooted, the iron wire is removed. It is best not to press the soil to prevent decay; secondly, use bamboo sticks and waste film around each melon. Made of a 60CM high windshield.



    2, timely picking, pollination and preservation of the main vine.



    To remove the first female flower and the tendril before the flower, the side branches leave 2-3 leaves and pick the heart; the main vine grows to about 10 meters to pick the heart. At the beginning of July, two flowers, male flowers and female flowers, were formed, male flowers first appeared, then female flowers, pay attention to observe the time of female flowers. The female flowers are easily recognizable, and each flower has a green spherical handle at the base. These spherical handles are called ovary. Usually remove the first female flower on each melon, and save the second or third female flower. At this moment, the vine has grown to 2.5-3 meters, and pick a fresh male flower before 8 am. Repair the petals of the outer layer and shake the pollen on the stamens onto the stigma of the female flower. The female flowers that have occurred in the future will be removed;



    3, go to the melon. The youngest female flower of the second female flower and the third female flower is left to the size of the tennis ball, leaving one of the largest melons, and the other is removed in time;



    4. Fertilization.



    The position of the melon should be flattened, slightly raised, and leave a space of 1 square meter. At this stage, the melon must be trimmed. When the melon grows to 200 leaves, the top and side branches are removed. Ensure that the nutrients on the vines supply the growth of the pumpkin. When the vine grows root at the petiole of each leaf, the roots close to the pumpkin are broken, and then the growth space is supplied to the melon, and the other female flowers are removed together, so that all the nutrients are only supplied for one growth, then the pumpkin It will grow at a rate of about 9 kg per day. Increase water and fertilizer management. Because the leaves of melon are large and large, organic fertilizer is applied once every 5-7 days, 50-70 kg per plant, and 0.5 kg of nitrogen, phosphorus and potassium fertilizer.



    5, topdressing.



    It is necessary to dilute the composted manure at a distance of 1 meter from the melon, and participate in the nitrogen, phosphorus and potassium compound fertilizer, and pour it into the manure. For plants with fast growth, large vine leaves, and too fast fruit, the plants with the melon king's phase are mainly protected and specially cultivated. The fourth is to avoid pests and diseases in time. Entering the future in July. Climate change is prone to aphids and powdery mildew. In order to ensure the quality of green foods, pesticides of biological preparations should be selected once a week; powdery mildew should be controlled by pollution-free pesticide powder rust rust and green qingqing.



    6. Drainage.



    Into the dry season, we must do a good job of drainage around the melons to avoid rotten melons. Together, the rat poison is placed around the pumpkin, and the mouse damages the pumpkin to prevent the operation.



    7. Pest control.
