Watermelon sunflower planting is an effective stimulation measure for planting sunflower leaves. It has full use of growing season, changing seasons into two seasons, rational crop space layout, improving light energy utilization efficiency, combining land use and land, and improving space. Advantages such as utilization rate, optimization of planting structure, and common development of diversified operations. The following small series introduces you to the technology of planting sunflower leaves. Interplanting mode The high ridge and wide groove peritoneal cultivation mode is adopted. The width of the ridge is 1.4 to 1.5 m, the width of the groove is 0.7 to 0.8 m, and the height of the ridge is 0.15 to 0.20 m. The side ditch and the furrow are connected to each other to ensure smooth drainage. The ridge is covered with a 1.7 m wide transparent mulch. Watermelon is planted on the ridge. The watermelon seedlings are transplanted and transplanted first, and then planted. The live seeding is planted under the membrane. The seed is planted and mulched. The head-to-head planting is 1.2 m and the plant spacing is 0.8 m. Sunflowers are planted in the ridges and gullies, and two rows of oil sunflowers are planted with a row spacing of 0.6 m and a hole spacing of 0.3 m. Variety selection and seed treatment Watermelon chooses early-maturing, high-quality medium-sized fruit watermelon. Watermelon seeds are soaked in seeds, soaked in warm soup, and potassium permanganate soaking seeds to prevent seedling wilt, root rot, bacterial spot blight and the like. Sunflowers choose early-maturing, high-yield oil sunflower varieties. Plot selection and base fertilizer Choose sandy loam with high topography, deep soil layer, loose soil and fertile soil, good permeability and convenient drainage. It is best to have more than 5 years of plots without melons. Datian land preparation is carried out in autumn and winter irrigation, and the depth of winter water is more than 0.2 m. Re-application of organic fertilizer, 667 m2 of moderate fertility land combined with land preparation, one-time application of high-quality farmhouse fertilizers with harmless treatment of 2 500-3 000 kg, calcium acetate 3.3 kg or diammonium phosphate 2 kg and potassium sulfate compound fertilizer 2 kg. Seeding points Watermelon is properly planted early, when the ground temperature of 10 cm is stable above 15 °C, the temperature in the early morning is not lower than 5 °C, and the planting is carried out in mid-April in the Yinbei area. The membrane cultivation mode is selected. After ridge ridge, the seeding hole is opened, the bottom water is poured, and the planting or sowing is carried out. After the seeding hole is covered, the soil surface or the top of the melon seedling is 3~4 cm lower than the glutinous surface, and the mulch is immediately covered, and the seedling is unearthed or After the temperature is stable, the membrane is ventilated in time, and the temperature rises to a suitable temperature for the growth of the melon seedlings. The melon seedlings are released from the membrane surface in the evening, and the membrane is sealed with soil. In mid-June, after the watermelon stabilized and entered the expansion period, the ditch was filled with water and sunflowers were planted in the ditch. Seed 2 to 4 seeds per hole, sowing depth 4 to 5 cm. Field management points The focus of field management is on the amount of fertilizer and the timing of fertilization. Only when sufficient fertilizer is applied can the crops grow normally and mature on time. The principle of fertilization: the base fertilizer should be applied, the topdressing should be timely, and the foliar fertilizer should be flexible. Excessive fertilization may result in only long leaves not blooming, and early maturity cannot be achieved. In the planting of watermelon, pay attention to adjust the growth of the plant, pruning the vines in time, thinning the fruits and vegetables, and ensuring the fruit setting rate. In order to ensure the rate of sunflower, the artificial artificial pollination should be carried out. Watermelon management The first true leaves of Miao Miao and Ding Miao watermelon were planted after the flat leaves, and one to two strains of strong seedlings were retained at each hole. When 5 to 6 true leaves were selected, one strong melon seedling was selected for each hole. When the seedlings are cut off at the base of the near-ground, they should not be removed. If the seedlings are lacking, they should be replanted in time. The cultivating and weeding watermelons are in the vine-growing stage and the flowering stage, and the fruit expansion period is combined with the pruning vines to remove the weeds between the ridges and the ditch. Sunflower field management When two seedlings of the seedlings were planted, the seedlings were planted, and the seedlings were replanted in time. After cultivating and weeding, the cultivating and weeding should be carried out in time. After the watermelon is harvested, the second cultivating and weeding is carried out. Pest Control The main pests and diseases of watermelon are rickets, blight, blight, anthracnose and mites. The treatment of squatting disease is sprayed with 72.2% Plex water 600 times liquid spray or 72% frost urea Mn-Zn wettable powder 600 times liquid spray; 98% carbendazim WP 2,000 times liquid is used for root blight control or 50% carbendazim WP 500 times solution; root blight control using 70% thiophanate-methyl WP 600 times solution or 50% chlorhexidine WP 1 200 times solution; anthracnose Use 70% thiophanate-methyl WP 600 times liquid spray, 10% high-water dispersible granule 600 times liquid spray or 2% agricultural anti-120 water 200 times liquid spray; mites control using 10% imidacloprid wettable powder 4 000 ~ 5 000 times liquid spray, 3% matrine solution 1500 times liquid spray or 5% fish vine essence oil 600 ~ 800 times liquid spray.
