Combination cultivation pumpkin corn

Combination cultivation pumpkin corn

The advantage of pumpkin and corn combination cultivation: It expands the scope of action of crops on light, moisture and nutrients, prolongs the time and space for the use of natural resources, increases resilience, and mitigates natural disasters; it can achieve the purpose of disease prevention and pest control. It helps to increase crop yields. The specific operating techniques are as follows: The plain fertilizing land that can be filled with energy and irrigation can be used as sandy loam, and the former pods can avoid solanaceae and melon vegetables. The pumpkin is deep-turned in a 2 meter 1 zone. Then, after sloping a plough with a depth of more than 30 cm, the sloping ridge is used to produce 3 m3 of high-quality farmyard fertilizer, 10 kg of potash fertilizer, 15-20 kg of diammonium, and 5 kg of urea. Each side was then turned over with a plough to make a planting platform 60 cm wide and 10 cm high. The pumpkin seeds should be sunned for 2 days, then soaked in warm soup for 6-8 hours, remove and dry the water, germinate at 30°C, and sow when 50% of the mouth is twisted. Seed sowing in late April - early May, corn sowing in mid-May, waterlogging is not good to sit, pumpkin plant spacing 35 cm, 2-3 per litter, cover soil 3 cm, slightly suppress, poison valley 2 - 2.5 kg/mu, then cover the film. Corn is planted between two ridges of squash with a 45 cm spacing. Field Management: Pumpkins emerged 7 days after sowing. This period requires not only freezing seedlings but also anti-hot sprouts, 3 true leaf seedlings, 4-5 true leaf Ding Miao, 900 mu seedlings per mu, and 750 Mu Miao seedlings. When the true leaves are 6-7 pieces, according to the direction of creeping, the soil is cultivated and the quail grows in the same direction. Before extending the vines, each side of the planting platform needs to be plowed on both sides so that the water can be irrigated, and shovels and weeds can be diligently shovelled. The pruning method is single vine pruning, leaving the main branch to the side branches; the pressure vine is shoveling off the dry earth outside the melon posterior section and pressing the vine with wet soil; the tine point is at the first 5-6 leaves of the first melon. Get rid of the main tip and press the vine with wet earth. Artificial pollination is performed at 4-9 am in the morning, collecting male flowers that have not been opened, and using the anthers inside to gently apply to the stigma of the blooming pistil. The management of fertilizer and water is no drought or watering, and the bottom is full of fat and no need of topdressing. The root melon should be removed as soon as possible. When the first melon apple is large, the topdressing urea 15-20 kg, according to the soil moisture irrigation, melons do not end when the irrigation, flowering results, it is best to spray once every 7-10 days of phosphorus and potassium foliar fertilizer. To promote precocity is to bring the melons under the stage to the stage and fully see the light. Turn the melon yin to the yang side, remove the shady leaves of the melon, and pad the grass or stone pieces on the melon.
