Cultivation Technique of Western Pumpkin

Western pumpkin, also known as chestnut-flavored pumpkin, is a type of Indian pumpkin type. Since its introduction into China, its planting area has expanded rapidly with its beautiful appearance, excellent quality and unique flavor. Currently, there are two types of squash in the market, red and green. Compared with Chinese squash, Western squash has the advantages of precocity and cold resistance, but its resistance is poor and it is not wet and hot. The cultivation techniques are now described as follows: I. Seasonal cultivation In the climate conditions of Guangdong, the squash is most suitable for planting in the spring. Planting in the autumn due to high temperature and dryness, the virus disease is very serious and will result in reduced production or even loss. In greenhouse conditions, winter can also be planted. The sowing period for spring planting is January-February, and transplanting with seedlings is adopted. Winter Seeds are sown in mid-and late October and germinated. Second, sowing seedlings placed in 55 °C hot water immersion, natural cooling, about 4 hours later picked up, washed with warm water 2-3 times, and then wrap the wet towel wrapped in 30 °C under conditions of germination After the buds grow, they can be sown. The nutritious soil in the nutrition cup before sowing is to be leached, and the nutritious soil is mixed with mushroom slag or dry manure and rice field soil plus 1% of superphosphate and then sieved and sieved. Each soy cup was sown with 1 grain, about 1 cm thick after sowing, and then 1 water. The nursery takes place in a small shed or a greenhouse. The cotyledon leaves the shed film before unearthing, raising the temperature to promote emergence. When most of the cotyledons are unearthed, the humidity in the shelter must be reduced. After the seedlings grow out of the true leaves, the leaf fertilizer is sprayed once every 5-7 days. Seedling fertilizer thiophanate 800-1000 times leaching 1-2 times, this period of insect pests is mainly Huang Shougua, can be used to kill 800 times the trichlorfon. When the seedlings grow to 2-4 true leaves, they are selected for transplanting on sunny afternoons. Third, transplanting planting stilts, open drainage ditch around. Climbing ground cultivation 畦 2.5 meters wide, single row plant, spacing 0.6 meters; scaffolding cultivation 畦 1.8 meters wide, double row planting, spacing 0.55 meters. After the planting of the ditch, 2000-3000 kg of organic fertilizer, 30 kg of compound fertilizer, and 1.5-2.0 kg of Miller were returned to the soil. With soil transplant, pouring enough water. Fourth, field management after the timely emergence of seedlings with 0.5% urea or compound fertilizer watering 2-3 times. Extension of vines combined with cultivating soil Mushi compound fertilizer 20 kg, 10 kg urea. Remove the side vines, leave the main vine, and climb the ground to cultivate. During the growth period and later period, attention should be paid to timely removal of the old leaves, diseased leaves, and yellow leaves of the plant's base. Generally from the second female flower, choose to stay strong Fruit. One to two days before flowering, leave 2-3 leaves before the seed vine and then topping. To improve fruit setting rate, artificial pollination should be performed in the morning during flowering. After the fruit period, Mushi compound fertilizer 30 kg, combined with spraying and spraying foliar fertilizer. In the result period, the amount of water required is large, and the supply of water must be maintained. The main diseases of the Western squash are infected with white powder and the viral glassy blight can be controlled by 600 times of chlorothalonil or Rhizoctonia, sprayed once every 7-10 days, and sprayed 3-4 times in succession; powdery mildew can be used to prevent and cure 1000-1500 times of triadimefon. , spray every 15-20 days, continuous spray 2-3 times; virus disease is mainly to control the aphid infection, the early onset of the plant should be timely unplugged. Insect pests mainly include aphids, fruit flies, etc., and aphids can be treated with dimethoate or dichlorvos 800-1000 times; cucurbits can be controlled 1500 times or 800-1000 times of dichlorvos, and sprayed once every 3-5 days. repeatedly. V. Timely harvesting of Western squash is generally 40-45 days after pollination for harvesting, and can be cut and harvested with a knife.
