Friends who are more interested in tourism agriculture or who have participated in such activities as agricultural carnivals must not be unfamiliar with giant pumpkins, which are dozens of times larger than the average pumpkins in the market, and weigh hundreds of pounds or even thousands of pounds。
The chinese news network, the china network, the china jiangsu network, yang zhi, the modern express, jiangsu tv, the cebu television, the cebu mobile phone station, the cebu night post, the rapid news, the phoenix network, the 100-degree network, the new wave network, the fox search network, the globe network, the zeng zai network, the north qing network, and 1,000 other media outlets made a national statement。
In fact, in the americas, where giant pumpkins are produced, the most common variety is the giant pumpkins of the united states, which weigh more than 100 pounds in single fruit, and where domestic cultivation has a record of over 100 pounds, red, white and yellow, which are highly regarded by tourists in the landscape, as well as the prospect of technological progress in modern agricultural breeding, which is the highlight of general agricultural education, which is welcomed by the planters
Varieties selection
The united states giant pumpkin species were selected for 110 days, with leaves of 70 centimetres in width, strong roots, thick rods, strong growth, deep red, fruit ellipses。
Facility selection
Growing large pumpkins, which are over 70 centimetres wide, have a weak pole, are prone to wind blows and are injured by heavy rains, and therefore choose to grow in large sheds。
Choice of production period
There are two main problems in the south in the production of large sheds, namely, high temperatures of over 40 degrees in the summer months of july and august and the susceptibility of leaves to atrophy, causing melon deformation and viral infections; and winter, in the month of january and february, the number of days was high, the light was short, thin and even growing. As production staggered as much as possible, the two months in the south that would be most suitable for giant pumpkin cultivation in the sheds were march and september。
Base
The use of artificially formulated substrates, which have the advantage of perturbation, strong root system growth, rapid growth and significant productivity gains, can effectively reduce planting costs by comparison to peat 60c/o, organic fatty 30c/o, pearl rock 5c/o, coconut 5c/o, or by choosing mono-planting soil。
Nutrient fluid formulation
Irritation using full-nutrient formulations has the advantage of full nutrients, high growth rates and high radiance of fruit. Per nitro calcium 850 mgl, potassium nitrate 400 mgl, magnesium sulfate 300 mgl, ammonium dihydrophosphate 150 mgl, sequestered iron 16 mgl, borate 3 mgl, zinc sulphate 0. 22 mgl, manganese sulphate 2 mgl, copper sulphate 0. 08 mgl, ammonium sulphate 0. 02 mgl; adjustment of water fertilizer concentration ec value 3. 7, approximately 1,000 pounds of full water distribution formula and irrigation。
Nursery management
Seed treatment: insulation of seeds with hot water at 55°c, continuous mixing, continued 24 hours after cooling and then placed in a 30°c seedling box, which normally occurs 24 hours later。
2 cultivation: using pre-plant and post-plant management, seedlings can be easily controlled and seeded directly in a 13 x 15 cm glass of soft plastic with seedlings, with a single seed, usually for about 15 days, when the seed reaches a core of two leaves. Shrimp can be administered 2-3 times, with the option of virulent, polybacterial。
Plantation management
1. Specification of planting pits: 70 cm deep, 1 m wide and 1 m long, with a distance of 2 m and approximately 9 m long, ensuring about 18 m2 of growth space per seed. Fill in the matrix and plant a seedling in each pit。
2. Pipefill requirements: care should be taken to fill the pits with approximately 30 cm above the ground to prevent overwatering and leaks in the sheds from causing rooting. The surface matrix should be stacked high on the edges of the surrounding area, with an indentation in the middle, which would facilitate planting and subsequent watering。
3 base-based treatment: each pit matrix must be sterilized, with the option of placing thiophos-methyl with multibactrin, with approximately 60 kg of potion per pit. The treatment of the matrix will take place two days before the planting。
Four reptiles: the seedlings of the day before the seedlings can be reploughed with multibacterium as a delivery drug. The seedlings are easily removed from plastic cups and planted in the middle of the planting pits, with the option of the stench being administered on the fifth day of planting。
Fertilizer management
A week after planting, fat water begins to be poured out with a fully prepared whole trophic fluid; there are fewer leaves in the front and 30 kilograms of nutrients per tree; after half a month of planting, the leaves grow rapidly, consume more nutrients and enter the long term, each of which is 60 pounds of nutrients, usually every seven days. Water is poured every two to three days, depending on the dry and wet base, and it is prohibited to water and fatten at noon in the summer。
Temperature control
When temperatures reach 35°c, sunnets must be opened to cool, with the conditional use of wind machine wet curtains to cool; during continuous high temperatures, care must be taken to treat viral diseases; and when temperatures are too high and shrunk, melon deformities and effects can increase. The highest temperature of growing pumpkins in the long term is maintained at 20-30°c。
Roast management
1. Watering of the penis: in order to prevent the foliage of the wind and the agricultural operations from swirling the seedlings, water should be used to induce the growth of the main chicken, which can be watered every 2-3 days. The chicken can be free of water, reduce air moisture and prevent serious disease. When the main chicken begins to leave the melon, the space around one metre around the part of the fruit should be prohibited from unsettling the growth of the root, preventing the pumpkin from growing and cutting off the rod。
Powdered melons: they are found on the main chickens, and the fruit expands at a high rate, with good quality, and some 40 days after planting, and the number of single leaves is around 200, so that they can be removed from all the pre-results. The first one should generally be removed and easily deformed. The remaining melons must be pollinated by hand and be pollinated by 10 a. M.; the male flowers that were opened on the day are extracted, the petals are cut out, the pollen is gently painted on the female column, and each female is pollinated by two to three males. Each seedling pollinates 2-3 females in succession, and when the fruit grows to tennis hours, selects a fast-growing, sharp-cut melon, and removes the rest. A single fruit for each seedling is selected to concentrate on the use of photocolumn products, to achieve the full growth potential of the species and to achieve the high yield effect of single melons。
3 the whole of the chickens: in order to make it easier for the fruit plate to be fertilized, the blades of the tubing base can be properly trimmed, and should be chosen for a better day of midday, with care to keep the two centimetres of the lobes free of their formation, so that they do not cause injury to the main chicken, and so that the wounds are extended; in order for production to achieve a high yield on a single scale, it is necessary to ensure that there are sufficient leaves and leaves the leaves to grow freely, as soon as the gourd sits down, up to the full hours of the tennis ball, then the main chickens and the flanks will be dealt with, so that the weight of the growth will shift to the expansion。
Flower fruit management
1 pumpkin: when a guacamole is pollinated, it needs to be covered with foam or plastic flounders to prevent the guacamole from touching the condensed ground and crushing the bark。
2. Picking flowers: a particularly large number of males can grow throughout their growing life, and if they are allowed to grow freely, they can be decayed and decomposed, causing a high accumulation of bacteria and causing disease, so that too many males should be removed every day。
3- cholons: to produce the right end of the fruit, the ellipses and the lower pumpkins of the fruit, they need to be processed. Select a strong and strong female who will rise up two days before opening up, and can be used to bandage the female into a 25 cm parallel bamboo frame above the ground, lifting the seedling to the surface, so that after pollination, its larvae will grow naturally due to gravity. When guati is completely down, the bamboo stand can be removed and the larvae can continue to grow on the floor foam。
4. Pumpkin engraving: in order to enhance the artistic character of the pumpkin culture, it is possible to produce long, written pumpkins and enhance their value. The method is to post it on the fruit side of the pumpkin with a printed 4a paper 35 days after pollination, and then stab it on the face with a nail that looks at the contours of the text and rips the paper off when it's finished, which will heal for about a week。
Lifting melons: some 50 days after pollination, the melons are almost mature, in order to create a good landscape, attract a presence, photograph tourists and lift them up. It can be lifted up to about 40 centimeters, with a wooden bench or a cask under it, and a foam sheet on it and a light lifting of the melon. Each dose can be properly applied with leaf-leaf fat to promote growth. Pre-situation urea can be used, which helps to grow the leaves; and post-situation potassium phosphate, which helps to develop the fruit. The use concentration was 2 to 3 per thousand。
