Fighting melons is a type of watermelon, but the main thing is to take its seed food, fragrant and beautiful, high nutritional value. As the international market demand for squash seeds soared, the price of squash seeds climbed all the way, and the output benefits of planting smashed saplings have become apparent. However, the output of the seeds is very different. The taller ones can produce more than 150 kilograms of melon seeds, and the lower ones only have tens of kilograms. In order for the majority of farmers to plant melons to obtain higher economic benefits, the author's experience in guiding melon planting for several years to achieve high yields is summarized below. First, soil preparation Fighting melons for fear of water stains and avoiding heavy squeezing, we must choose topography and high dryness, where the soil is deep, fertile and loose. The loam and sandy loam soil is convenient for drainage and irrigation, followed by sand, clay, and saline-alkali land. Former crops of leguminous and corn crops were better, followed by wheat, cotton and sunflower. More than three years of rotation are required to help prevent disease and avoid heavy lifting. 2. Based on the deep winter ploughing before winter, the springs will be ditched and ditched, and the ditch will be 130-150 cm away. Poor soil fertility may be appropriately wider so that full use of land can be achieved. The width of the ditch is 30 centimeters, and the three ditches inside and outside are matched to facilitate irrigation and drainage. Before sowing, 666.7 square meters of diammonium phosphate 10 kilograms, high-efficiency compound fertilizer 15 kilograms, it is best to mix with fermented organic fertilizer or oil residue applied to the slope of the ditch 30 cm and applied to the ditch bottom, depth 15 cm. Second, suitable for early broadcast Choose good breeds. The best varieties of melons are New Seed Melon No.1 and Lanzhou Big Pieces. The purity of the variety is required to be over 95% and the germination rate is above 90%. Good varieties of melon seeds are pure, full, and easy to eat. 2. Seed treatment. (1) Sowing before seeding for 1-2 days will help increase the germination rate. (2) Soaking in warm water: Seed germs can be killed by soaking in warm water of 55°C for 12 hours. Soaking seeds at 25-35°C for 12 hours earlier can germinate. The seed weight of 25% carbendazim WP of seed weight was used. 3. Film sowing. The use of mulch cultivation is conducive to early germination, conservation and elimination of weeds, is an important part of the high yield of melon farming. When the temperature of 5 centimeters stably passes through 14 degrees Celsius, the film can be sown. The best sowing date is from late April to early May. After the first cover film is used, seeding can be prevented to prevent seedlings from sprouting. With 90 cm of film, the entire ditch can be covered with flat, homogeneous, tight and solid material. That is, the land is flat, the film is laid out neatly, the film is laid tight with the ground, and the film is compacted with soil. Let the wind blow. After the film is covered, the caves are sown. After sowing, the holes are covered with fine wet soil and the holes are closed. According to the hole distance 20~25 centimeters sowing, 2-3 tablets per hole, depth 3 centimeters, sowing volume 3 kilograms/666.7 square meters, keep seedlings 3200-3600 strains. At the same time with 50% acetochlor aqueous solution 75 ~ 100 ml, watered 40 ~ 50 kg of mulching surface soil, and then cover the ultra-fine plastic film, film around the tight and compacted with soil, can effectively control weeds. Third, strengthen field management. Timely seedlings. Dingmiao sooner rather than later, usually leave a single plant per hole, the lack of seedlings will leave two plants on both sides, lack of seedlings more than 2 artificial germination replant. 2. Pruning pressure vines. When the melon grows to 6 true leaves, the vine grows 10-15 centimeters in length, and the man-made crushed man-made pieces are used in time to prevent the winds from entangling the melon vines together, resulting in a low rate of sitting cucumbers. 3. Reasonable fertilization and irrigation: According to the production of the melon, according to the weather, the soil to determine the first irrigation time, generally the first time in the water in the middle and late June, combined irrigation artificial nest application of urea 15-20 kg / 666.7 square meters . To grasp the slow growth of weak seedlings can be early irrigation, Wang Miao can postponed irrigation, fertilization. Fertilization applied at a depth of 20 cm from the root of 10 to 15 cm, less seedlings, weak seedlings applied. Every 10-15 days after the irrigation of a water, the second water fertilization based on the growth of urea 10 kg / 666.7 square meters. Water is usually watered 5-6 times throughout the growing season. The last water stop time is in late August. 4. Pest Control. The main diseases that harm the fight melon are wilt disease, anthrax, downy mildew, powdery mildew, and viral diseases. In addition to the need to take reasonable rotation, nurturing strong seedlings, deep trenches and high-row planting and other agricultural measures, they should also conduct chemical control against different diseases. Among them, powdery mildew is one of the most serious diseases of our region. The disease usually begins in the middle and early July, and prevention and treatment should be emphasized. In the seedling stage, the regimental stage, and the extension of the initial stage, the tyrophanatine and pink Xiuning can be used for alternate spray control. Pests that harm melons are mainly locusts, ground tigers, and red spiders. In addition to sowing, 1.5-2.2 kg/666.7 square meters of carbofuran can be used, and digoto, fast killing spirit and dicofol can be used for prevention and control. Fourth, harvest drying 1. The purpose of cultivating melons is to harvest full melon seeds. Therefore, the seeds must be fully matured before harvesting. Fighting melons generally matures, and can be appropriately delayed with a seedling machine for harvesting. 2. After harvesting, it should be placed in the open sunny place for drying, and it should be turned frequently. It should be sunned until the shell and the shell collided with each other and the sound can be made. The drying is not too dry. Pay attention to remove the seeds after drying often to flip, in order to prevent melon seeds on one side of the water loss and contraction curling too quickly, affecting the quality; at the same time should also pay attention to continuous rainy days not be harvested to prevent mildew. The cool sun of melon seeds is the last step in melon planting. The quality of drying must be guaranteed to increase the commodity rate of melon seeds and enhance the competitiveness in the market.
