1. The greenhouses and basic facilities in the shed require that the steel sheds with a span of 60 meters or more and a height of 2.2 meters or more should be the best. The sheds and the vents on both sides of the shed should be equipped with insect nets. The sheds are equipped with 5 The length of the iron wire, which is equal to or longer than the length of the greenhouse, is 4 to 6 meters long and each wire is equipped with a 1.8 to 2 meter bamboo pile or cement pile as the basic skeleton for vertical cultivation. 2. Vertical efficient cultivation techniques (1) Variety selection and sowing. In the Yangtze River Delta region, wet and heat-tolerant varieties that are suitable for the autumn climate should be selected, and there are mainly varieties of sea honey series such as melon, cui honey, and Xiboluotuo. The general sowing date is arranged from the end of July to the beginning of August. The nursery net is covered with a small shed to protect the seedlings. The time for the autumn seedling raising is short, and the seedling ramie soil can be used with 5 kg of rotten cake fat per 20 square meters. Dry seed sowing, planting water before sowing, sowing after the seeding a layer of insect nets, and then build a small arch shed, a small shed on the first cover a layer of insect nets, and then cover the old film and shade nets. 2 to 4 days after emergence. After the emergence, the cover insect nets, plastic films and shade nets were gradually removed, and the insect nets on the small arch shelters were preserved to prevent pests from injuring the seedlings. Early autumn nursery should always pay attention to cooling and moisturizing. (2) Fertilization, site preparation and planting. After clearing the former crops and weeds in the greenhouse, each 667 square meters (1 mu) shall be planted with 200 kg of decomposed cake fertilizer or 1 to 1.5 tons of decomposed chicken manure - sorghum. About 1.2 meters wide and 20 centimeters high. 15 to 20 cm away from the center of the surface of the raft, the strip of potassium sulfate compound fertilizer is applied at a rate of 50 kg per 667 square meters. After spraying, apply 72% Dole 100-125g to 60kg of water and spread evenly to prevent weeding and cover the entire film. Drawstrings are drilled at a distance and the spacing between the rows is controlled between 40 and 45 cm. 10 to 14 days after the seedlings, 2 leaves and 1 heart can be selected for sunny afternoon or cloudy day for planting. (3) pruning fruit. In the early autumn, thick muskmelon has high growth temperature and fast growth. Generally single vine pruning, leaving 1 fruit per plant. The vines below the main vines were all removed, and the thirteenth to fifteenth vines were left as the result branches. The vines and the two leaves were picked up and the female flowers on the first section of each vine spread as the best part of melon growth. The main vine after the 25th section topping, in the main vine down to the number 3 to 5 at the left of two branches for their growth, in order to ensure the nutritional needs of the late growth of melon, the remaining sub-cranes before and after the size of the melon fruit eggs removed as soon as possible. The female flowers on the branches were soaked in the female flowers in the pre-opening period of 1 to 2 days with Styro® and each of the 900 to 1000 g of water in the package had wetted the female flowers, and the ovary began to inflate in 3 to 4 days. When the size of fruit and eggs is selected, each plant should have a regular fruit shape, long oval shape, and the largest amount of young melons. The wire hooks should be suspended from the wire at the cucurbits to prevent the melons from being damaged by gravity. (4) temperature and humidity management. During the autumn melon cultivation, the temperature is higher and the melon grows faster. The general maturing period of the late-maturing varieties is only 90 to 100 days. In the pre-growth period (before flowering), attention should be paid to cooling and ventilation should be maintained near the ground. In addition to the rainy weather, all ventilation openings should be opened at the same time, and pruning and other field management should be strengthened in time to prevent the plants from having too little female flower differentiation or difficulty in fruit set. When the size of fruit eggs (fruit enlargement period) should be watered once. (5) Pest control. The main diseases of melon in autumn are powdery mildew, downy mildew and aphids. In the early stage of growth, pests generally do not occur. After fruiting, the fruit enlargement period is prone to occur. The main problems are mainly integrated agricultural control. Powdery mildew can be controlled at 700-800 times in the early stage of the disease. Downy mildew can be controlled. After the fruit is poured into the water, it is sprayed with a 600-fold solution of arsenic, manganese and zinc to prevent the disease once. In the early stage of disease, alternate treatment with chlorothalonil and anti-virus is performed. The pests that damage melons in the fall are mainly aphids. If they occur locally, they can be treated with pyridoxine insecticide 1000 spray. When there is a large amount of occurrence, 500 ml of dichlorvos available per 667 square meters is mixed and fumigated on an evening rainy day. (Note: Do not use during flowering to prevent female flower yellowing). (6) timely harvest. The harvesting criteria of thick-skinned melons are determined according to the melon varieties and cultivation seasons. In general, the mature period of thick-skinned melons in autumn is about 10 days shorter than that in spring. When matured, the melon leaves tend to be withered, and the melon stalks are circled yellow. The specific harvesting time should be based on the characteristics of the varieties to make a good date for flowering. During fruit ripening, a small amount of samples should be taken and the tasting and soluble solids determinations should be followed to determine the time for mass harvesting. The cucurbits are preserved and “T†shaped when harvested, which is easy to prolong the storage and preservation period of the muskmelon.
