The American cucumber (f1) is an excellent cucumber variety imported from the United States by Anhui Huayi Food Co., Ltd., and it is exported to Japan as a raw material for pickling. Yaopu Agricultural Technology Station has been trial-planting since 1997. In 1998, it signed a contract with Anhui Huayi Food Co., Ltd. The economic benefit is very high, and the income per mu is about 3,000 yuan. First, the characteristics of varieties. The hybrid is a hybrid generation with a grain weight of 30 g, a fruit shape of 8.5-14 cm long, and a diameter of 3.4-4 cm. The plants are robust and strong, with strong leaves, large branches, strong fruit setting capacity, a vine length of about 250 cm, and a well-developed root system. In the soil layer within 30 centimeters of the ground surface, the horizontal growth is the main reason, and the regeneration ability is poor. It is suitable for sandy soil with good air permeability, and the soil pH value is 5.5-7.2. Second, the growth environment. Cucumbers are hi-temperature vegetables, and they are sensitive to high temperatures. They are suitable for transplanting in mid-April. The optimum temperature for growth is 22-26°C; it is sensitive to the ground temperature and stops growing when it is lower than 12°C. Strict requirements for soil moisture content, fear of waterlogging, require dual energy harvesting rice and wheat field, and in the past 2 years did not plant melons field. Third, soaking seedlings. The city of Luzhou breaks frost around April 10th, so the time for planting seedlings can be selected on March 5-8 in March. Sowing and growing seedlings are operated in the greenhouse. The greenhouse adopts a simple and large arch shed, which is 2 meters high and 6 meters wide. The shed must be sterilized prior to use. 1. Nutrition seedlings. Nutritional options are available: 10 cm high and 10 cm in diameter. The nutrient soil was selected from soils such as wall soil and rice paddy soil as nonnutritional soil and added with mature manure fertilizer. The ratio of soil to fertilizer was 6:4. 48% of compound fertilizer was added with 1.5 kg, a small amount of dead ash was added, and carbendazim was used. The liquid 1000 times liquid spray mix, move to the greenhouse to cover the film after 3 days and set aside. The coated seeds were soaked in water at 55°C for 2 hours, then spread on a breathable gauze, wrapped in a constant temperature environment and germinated for 24 hours. When the shoot length was 0.3-0.5 cm, the seeds were sown in time. Before sowing, use 72.2% Precike liquid to indulge, so that the crust is naturally concave, sowing the seeds in the middle, cover about 1 cm nutrient soil, be careful not to cover too thick or too thin, so as not to affect the uniformity of seedling emergence. Fourth, seedling management. After sowing, a small shed is placed on the well-arranged oysters. The shed is then covered with a flattened film (which is conducive to keeping the seedlings out of the seedlings). After 2 days, the tile is removed. 1. Shed temperature management. During the day, the greenhouse temperature is controlled at 20-25°C. When it is lower than 20°C, it must be heated in time to prevent cold damage. When it is higher than 24°C, it must be promptly released and the air should be kept away from the limelight. Do not let it go too fast and prevent the emergence of tall seedlings. The nighttime temperature should be controlled above 12°C. At the same time, the temperature difference between day and night should be managed to promote flower bud differentiation. In case of bad cold air, accompanied by frost, heavy snow, we must promptly do a good job outside the shed, warming work within the shed. 2, humidity management. The moisture content of the nutrition bowl should be controlled at 70% or more. When the clay soil becomes white, the water shall be replenished in time. At the same time, the humidity in the greenhouse shall not be too large (no film is selected for the film). 3, pull distance. When the seedling grows to 2 leaves and 1 heart, it must be pulled away in time (by the mutual friction of the leaves), to prevent the plants from forming crowded seedlings and weak seedlings. When necessary, take control to strengthen the seedlings. 4, control of pests and weeds. Diseases at the seedling stage mainly include epidemics, damping-off, and anthrax. Can be used 72.2% Prec 800 times and chlorothalonil control, or a combination of control. Less pests during seedling period, if found, can be used again and other net prevention. At the same time, weeds should be removed promptly. V. Preparation for land preparation and timely transplanting. Prepare land 1 month before transplanting, apply 5,000 kg of farmyard fertilizer per acre, plow deep into the soil, make a high ridge in the soil preparation, make 1 meter wide, 0.6 meter wide, 20-30 centimeters high, cucumber seedlings grow to 5-6 leaves (ie April 5-8) transplanted. One week before transplanting, the seedlings were gradually opened at night. Cucumber has poor anti-frost ability and should be transplanted after frost break. The specific method is to remove the melon seedlings from the cocoon and plant them in the cocoon. The cocoon soil exposes the ground to 2-3 cm, the spacing of the plants is 30-35 centimeters and 160 centimeters, and the acres are planted in 1191-1390 strains. After the frost-free period is postponed, small arches can be used for cultivation, cross-fertilization can be done next to the nutrition bowl, and 35 kg of compound fertilizer can be applied per acre. Soil irrigation can maintain enough water for 1 week, but water can not be accumulated to facilitate rapid tree growth. Sixth, field cultivation management 1, scaffolding, pruning. One week after transplanting, scaffolding was started (material used for bamboo rafts, etc.), arch height 1.7 meters, bamboo pole length 4.4 meters, net width 2.8 meters (mesh 10 cm 10 cm), covering fixed on the arch. Due to the strong branching force and fruit setting ability of this species, the branches and juvenile melons of the roots should be wiped out at 1-5 knots, and the melon vines should be tied and tied with straw. The main body is left as long as the vine is more than 1 meter long. The vines above the top of the shelf must be long and not slanted. 2, top dressing irrigation. In the first time of flowering, fertilizer should be applied 10 kg of Sanyuan compound fertilizer, according to the appropriate color topdressing nitrogen and potassium fertilizer, and according to growth and yield, top dressing every 7-10 days. When the soil moisture is low after topdressing, timely irrigation, but do not flood the water. 3, foliar spray fertilizer, chemical control. In order to increase the yield and quality of cucumber, foliar spray, chemical control and other measures can be adopted. The main application is foliar spraying of potassium dihydrogen phosphate, green wind 95 or Huimanfeng, and at the same time using dildoamine for chemical control to control vegetative growth and promote reproductive growth. 4, weeding weeding. The soil is often irrigated and easy to compact, and the cultivator should loosen the soil and remove the weeds. 5. Picking and listing. Can be picked 1 time sooner or later. Picking standard: First grade product, fruit length 8.5-12 cm, diameter 3.4-4 cm, straight fruit shape, no bending, no pest spots, no scars, the price is 2.2 yuan / kg. Secondary products: no fruit spots less than 14 centimeters in length and less than 5 centimeters in diameter, no spots, and the price is 0.70 yuan/kg. Foreign products: too thick as foreign goods. 6. Pest control. Daejeon’s pests and diseases mainly include epidemics, downy mildew, wilt disease, powdery mildew, anthrax, yellow-shouldered melons, red spiders, and roundworms. Diseases, downy mildew, can be controlled with 72.2% Prec 800 times; powdery mildew with 100 grams of triadimefon, spray 60 kilograms of water; blight, anthrax, chlorothalonil control available; aphids, yellow Shougua, can be used once Prevention and control; red spider can use broom net to control. In order to effectively control the development and spread of diseases, it can be combined with picking gourds to hit the old leaves at the bottom, and at the same time, a layer of thin straw is laid on the surface to prevent soil-borne diseases.
