Su Yuyin has a good taste, is soft, and has a unique aroma. It can be used for breakfast as well as soup seasoning and is popular with the people. Su Yuxi is relatively crude and easy to grow. If the management measures are in place, the yield per mu can reach 750 kg or more. Soil preparation and planting sites Su Yuxi should choose sandy loam soil with deep soil, fertile soil, convenient drainage and irrigation, and strong water retention and fertility conservation. Second, the fine soil preparation method is to use the method of plowing the whole field first to pulverize the soil and mash it up so that the soil reaches a certain depth and looseness so as to facilitate the rooting of the corn. Then open the ditch and make it 0.7 meters wide and 0.3 meters wide. Third, sowing 1, timely planting Su Yuxi suitable growth temperature of 18-32 °C, spring, summer and autumn can be planted. Spring maize should be sowed early in time to increase yield, and it is advisable to use sowing seeds in mid-February for direct seeding. Seedlings transplanted with seedlings should be covered with thin film to grow seedlings, and seedlings can be appropriately planted earlier; Summer maize should be avoided when pollinating. From mid-January to mid-August, hot weather can be selected from about mid-April; in autumn, in order to avoid the high temperature in the early stage of growth and to avoid frost in the late growth period, sowing should be done in late August. 2. Seed treatment before sowing, select sunny days for 5-6 hours, then soak the seed with cold water for 12-15 hours, or soak with warm water at 30°C for 5-8 hours, and then use 40% dimethoate emulsion 20 times liquid for seed dressing. , boring after 3 hours of sowing, can prevent the damage of underground pests, rats, etc. 3. Fine seeding (1) The planting type of reasonable close planting of Su Yuxi is small, and the planting density can be appropriately increased. Usually about 4500 plants per mu are suitable, and the density can be increased appropriately in summer and autumn. Open a hole planting, planting two rows per plant, 0.35 meters spacing. (2) Fine seeding using live seeding Mu before planting (acupuncture) roosting pigs, cattle, sheep manure and other organic fertilizer 1000 kg, potassium carbonate compound fertilizer 15 kg, 30 kg phosphate fertilizer as a base fertilizer, and then use faecal urine water or Clear water wet and planting points, and finally put two seeds in each planting hole and then cover the soil; apply 30 kg of potassium carbonate compound fertilizer to the seedbed per acre before planting in the soil for basal fertilization. Let the soaked noodles be soaked in the shallow ditch with a depth of about 5 cm, then level the noodles to prevent accumulation of water. The sowing specification is 1010 cm. It is worth noting that the fertilizer should be placed on one side of the hole and the seeds on the other side when sowing so as to avoid direct contact between the seed and the fertilizer and result in the phenomenon of “robust seed”. Field management First, timely fill seedlings, Dingmiao using live seedlings in the seedlings unearthed, in case of drought should be timely watering and loose soil moisture, to ensure the emergence of neat. 2.5-3 leaves after emergence, should check the seedlings, make up the seedlings, the seedlings of the seedlings nest with soil transplanted to the lack of seedlings to ensure that the whole seedlings. When 4-5 leaves, the seedlings and the seedlings are planted, the weak and strong, and the miscellaneous and diseased seedlings are removed, leaving only one plant per hole. The seedlings were transplanted and transplanted at 2.5-3 leaves of seedlings. Before transplanting, 1,000 mu of organic fertilizer, 15 kg of potassium carbonate compound fertilizer, and 25 kg of phosphorus fertilizer were used as base fertilizer for perishable pigs, cattle and sheep manure. A seedling is planted on a hole and the rooting water is poured after covering the soil. During transplanting, the fertilizer is applied on one side of the cave, and the seedlings are placed on the other side to avoid direct contact between the seedlings and the fertilizer and cause “burning seedlings”. When transplanting, transplant with soil as much as possible to improve the survival rate of transplanting. Second, timely top-dressing 1, light Miao Miao seedling root system less developed, the main application of quick-effect fertilizer, the specific approach is in the seedlings 3-4 leaves per acre with decomposed manure water 25-30 Tam or ammonium bicarbonate 5- 8 kg of water and 1500 kg of water are applied. 2, Qiao Shi strong stalked corn 6-8 leaves, Mushi composted manure water plus 7.5 kg urea 25-30 or 7.5 kilograms of potassium sulfate compound fertilizer leaching solution 1500 kg, weak seedlings more facilities, and promote whole field balanced growth. 3, re-apply for attacking manure to grasp in the big bell-mouth period (11-12 leaves) 2-3 days before the replanting attack period, Mushi potassium sulfate compound fertilizer 20 kg + potassium sulfate 5 kg + 5 kg of urea, Fertilizer strips were applied to the fertilization ditch in the middle row of two rows of corn and finally covered with soil. 4, precocious attack grain fertilizer corn tassel can be applied to 10 acres of urea, increase the weight of single corn, but also can be used potassium dihydrogen phosphate, plant treasure, etc. for extra-root fertilizer after 1-2 times to improve the seed setting rate. Third, the rational use of water at the seedling stage of corn less water, especially seedlings will be immersed in the root system activity will weaken, resulting in plant yellow, and even death. After jointing, that is, 6-8 leaves, the plant water requirement increases, especially before and after the tasselling and flowering, which is most sensitive to moisture. Therefore, the field should be kept moist at the heading filling stage. 4. When weeding and earth-cultivating corn 6-8 leaves, combine fertilization, soil loosening, and weeding to carry out small earth-cultivation. The specific approach is to cultivate the ditch-bottom soil on both sides of the plant. During the big bell-mouth period of corn, the third fertilization is used to fertilize the soil to ensure that the roots are not exposed, the resistance to plant lodging is increased, and the nutrient absorption area is increased. This not only moistens and protects fertilizer, but also facilitates drainage and irrigation. Fifth, to smashing, smashing 苞 Su 糯 糯 糯 糯 糯 基 基 基 基 基 基 基 基 基 基 基 基 基 基 基 基 基 基 基 基 基 基 过 过 过 过 过 过 过 过 过 为 为 为 为 为 为 为 为 为. Before pollination, corn should be stripped according to the growing condition of the corn, and the strong seedlings with strong nutrition supply should be kept in the second crop, and the weak seedlings with weak growth and many diseases and insects should be left behind. Pest control I. Controlling seedling pests (1) Earth tigers: Irrigate with roots 800 times with phoxim. (2) Mythimna separata, Spodoptera litura: use 0.1 kg Jinyun biological pesticides to water 50 kilograms or Badan plus dimethoate 1500 times solution. Second, prevention and treatment of insect pests in the middle and late (1) corn borer: should be in the big bell mouth period, mu 1.5 kg Miller mixed sand 10 kg cast in the bell mouth. After pollination, 0.1 kg of Jinyun Bio-pesticide is used to prevent and control 2-3 times of 50 kg of water, which can effectively prevent corn borer from harming corn borer. (2) Mythimna separata, silkworm, aphid: In the heading and silking stage, dipterex and fleas were used to control 1500 times. 3. Rat pests In areas where the rodent damage is particularly severe, 10 days before sowing and 15 days before harvest, poison valleys made of sodium salt and rice of enemy mice are applied to the field for poisoning rats. Fourth, disease prevention 1, sheath blight with jinggangmycin powder 1000 times or Jinggangmycin water 200 times liquid for prevention and treatment. 2, the size of leaf spot can be used 600 times Ruizhi mildew, Longkei 800-1000 times solution or thiophanate-methyl 800 times to control. 3. Rust can be controlled by 2000 times of triadimefon or agricultural streptomycin. Timely harvest When corn glutinous leaves turn white, dried silk, and full grain, you can harvest. At the time of harvest, 4-5 loquat leaves should be retained to facilitate preservation and prolong storage time. China Agricultural Network Editor
