The way giant pumpkins grow
One, pre-plant
(1) selection of cultivation sites
Magnificent pumpkins have a suitable growth temperature of 25 to 35°c, with the northern region generally opting to grow in early april, while the southern region can grow in early march and be planted in cold sheds or solar greenhouses。
(2) digging cultivation pits
The soil is chosen to be grown on a boundary or sandy soil with a pit of approximately 1 m deep, 1. 5 m long, 1 m wide, 4 m long and 12 m long。
(3) criteria for filling pits
The fillings are mixed with sand, grass-grass, pearl rock, etc., to increase soil permeability and to combat oxygen deficiency at the root, with 100 kg of organic and 3 kg of compound fertilizer being mixed for each pit. The pit needs to be filled slightly above the ground and then watered and ready for planting。
2. Cultivation
(1) the seedlings
Magnificent pumpkin seeds are larger, their shell is hard, they are burned with 55°c warm water, they are constantly mixed up to about 30°c, then impregnated for four hours, so that the seeds remain humid with wet towels in an environment of 25-30°c, after which the seeds grow. Owing to the size of the giant pumpkin seedlings, all the nutrients selected to be 15 cm in diameter are primed, water is poured through, 2 cm incubated, seeded, covered, soil moist, placed in an environment of 25-30 °c, and the seedlings can grow in about three to five days。
(2) deplantation
The seedlings grow by three leaves and grow faster, for about 15 days, in time for planting. When planting, choose the morning of the sun, remove the nutrients of the seedlings, plant the whole at the pit centre, take care to minimize the damage to the roots and then pour water, and if the temperature is low at night, build small arches to prevent colding during the seeding period。
3. Fertilizer management
During the preplant period, no water is required, approximately 15 days later, the pumpkins begin to climb the chickens, then water fattening the water, which is lower in the preplant period, usually with a kilo of high nitrogen fat, which is to be melted into the water, which is to be watered together, gradually increasing the amount of water used, depending on the growth of the plant, as much as possible, to one per week. It is important to maintain an adequate water supply during the critical period during which high potassium fertilizer will be applied in the latter stages of the melons, promoting the expansion of the fruits and the expansion of the fruits, especially during the 40-day period of pollination。
The whole pollination
(1) the whole chicken
The whole branch is dominated by single chickens, which are left every one metre, which are about three metres to the top, both to ensure a sufficient number of leaves and to keep the leaves ventilated and luminous, with care to reduce nutrient consumption throughout the whole reproductive period by reducing the number of grandchildren and useless flowers. Pumpkin chickens are pressed every 1 metre, promoting root growth of the tuber, providing better nutrition for the plant, and the whole branch tends to grow every 3 days during the boom period, preventing excessive nutrient growth, especially in the early stages of the smelt, where control of the top edge of the plant favours the smelt。
(2) pollination
After 40 to 50 days of planting, the main chicken grows about 7 to 8 metres, choosing the right place to pollinate, preferably at 7 to 9 a. M., choosing the blooming male, tearing out the petals, rubbing on the female column, ensuring that the paint is even and that dew is avoided, affecting the quality of pollination。
5. Salmon harvesting
Magnificent pumpkins will grow up and should be kept dry with the ground and protected from decomposition at the bottom, preferably by preparing a stairwell in advance, and it is a good way to get air out of the bottom. When giant pumpkins grow up to 60 days, they can be harvested to prevent dry ventilation and can be stored for five months. In the process of carrying them, they are mainly designed to prevent the break-up of the melon, which is detrimental to its preservation。
6. Pest management
Magnificent pumpkins are more resistant to disease, with the main diseases being powdered and viral diseases, which can be treated with trisulfon 800 times the fluid or 1,000 times the ester ether. The virus is mainly preventable, with early cultivation avoiding hot, wet weather and long-term attention to the prevention of white lice and aphids. For white powder lice, 1,000 times the ethyl ester or aphid. Fifteen hundred times the liquid control and yellow vermin, which can be treated with 1,500 times the aphid or 1,000 times the aphid。
