The genus Cucurbita is a member of the genus Cucurbita, an annual herbaceous creeping dicotyledonous plant. Because it contains a variety of nutrients and minerals, it can be used not only as a food processing but also as an important raw material for pharmaceuticals. The squash can be cultivated in the greenhouse, can be matured earlier, improve the quality, and the economic benefit will be higher. The pollution-free cultivation techniques of the squash in greenhouses are introduced as follows for reference by farmers: The choice of varieties is bright and bright, and the flavor is good, suitable for local cultivation. Pumpkin variety. Seed soaking First, soak the seeds in water of 50Â°C for 15 minutes, pour water and stir with an alcohol thermometer to keep the water temperature at 50Â°C for 15 minutes; then let the water temperature drop to 30Â°C and soak for 1 to 2 hours. And remove the mucus from the surface of the seed, wash it, remove it and put it in the germination vessel, and cover the moisture absorbent cloth. Germination The germination vessel containing the soaked seeds is germinated at a constant temperature of 25Â° C. to 30Â° C. to maintain the moisture content of the moisture-absorbing cloth, and it is turned 3 to 4 times a day, and shoots can be taken after 48 hours. Prepare nutrition soil before sowing. Prepare strong seedlings. Nutrient soil should have the following conditions: fertile loose, water and fertilizer, no pests and weed seeds. Nutrient soil ratio: 40% of Datian soil, 40% of decomposed farmyard fertilizer, and 20% of peat soil. Mix the three and sieve. Disinfection of the nutrient soil was carried out at a ratio of 200 ml of formalin and 25 kg of water per 1000 kg of bed soil and mixed until piled up. Then cover with plastic film stuffy soil for 2 to 3 days to kill bacteria. The plastic film is then peeled off after 10 to 15 days, so that the drug odor is volatilized and then loaded into the nutritional bowl. Seeding nursery and seedling management sowing seedlings will urge the budded pumpkin seeds into a nutrient bowl preliminarily filled with nutrient soil, one for each pod, then cover 1.5 cm thick sterile nutrient soil, and then cover with a plastic film to keep certain The temperature and humidity. Seedling management after seedling management after sowing, with emphasis on heat preservation and moisturizing to accelerate seedling emergence. When it is found that the soil in the nutritional bowl is dry, it should be poured with warm water at about 25Â°C in time, not too much, to prevent bad species, when 80% When the above seedlings are unearthed, they shall be prevented from becoming leggy. Seedlings and seedlings management: After the seedlings are released, sufficient light must be ensured. At the same time, the temperature should be controlled between 20Â°C and 25Â°C, and the night temperature should be between 15Â°C and 18Â°C. The ground temperature is between 20Â°C and 23Â°C. In order to increase the root mass and cultivate strong seedlings, the seedlings shall be poured in time and thoroughly soaked in bottom water. Prevention and treatment of plant diseases and insect pests damping-off, damping-off disease control: a reasonable rotation, a reasonable close planting, the diseased plant was found to be removed in a timely manner. Combine with biocides for control. Insect pests are generally cockroaches, cockroaches, locusts, etc., and can be controlled by biocides, Sutrins. The first criterion for colonization and colonization is that the soil temperature in the shed within 10 cm of the shed should be stable at 8Â°C for 5 consecutive days; the second is that the seedlings reach 5 true leaves (about 35 days) and they have been trained; Buckled film cultivation can be planted 4 to 5 days in advance. Planting methods and colonization density Planting methods can be divided into two types: one is defragmentation of mulching membranes, and the method of colonizing a ridge and a ridge can be used, that is, the row spacing is 140 cm, and the spacing is 48 cm; the second is the colonization of buckled pellicles, which can be used for colonization. The method of ridges and ridges is 210 cm spacing and 32 cm spacing. This method is to make full use of the creeping characteristics of the pumpkin to regulate the structure of the population. Pay attention to about 1000 strains per mu. Field management During the vegetative growth of pumpkins, care should be taken to maintain temperature and humidity, timely ventilation, and cultivating and weeding. During fertility growth, fertilize regularly: after cultivating the vines for the first time, topdressing urea when combined with ridge closure. The second time the fruit diameter increased to about 12 cm, topdressing compound fertilizer containing phosphorus and potassium and organic fertilizer. Timely pruning pressure vines: pruning is mainly taken single vine pruning, leaving only one main vine per plant, side vines all removed, vine pressure is in the melon after the two sections of the vine on the leaf pressure. As the greenhouse is restricted by ventilation, artificial pollination is needed. General pollination time in the morning 5 ~ 9 is appropriate. Pest control Pesticide control Powdery mildew: The disease can occur during the entire growth period. It can be treated with 15% triadimefon 2500 times or 30% DT suspension 500 times. Bacterial keratosis control: Streptomycin can be used for 1 million units of 3 water and 15 kg of foliar spray. Insect pests are locusts and ladybugs, which can be sprayed with 15 grams of water on a 25-gram surface of Sutherine, a biocide. After harvesting pumpkin flowers, a layer of white waxy substance appeared on the surface of the pumpkin and there were many tiny nodules. This is a sign that the pumpkin is fully mature and should be harvested and marketed in time.
