Peanut disposable full-layer fertilization cultivation techniques refer to the one-time application of fertilizers that need to be absorbed in peanuts as base fertilizer before planting, and no additional cultivation techniques during the growth of peanuts. This technology has the characteristics of increasing production, saving labor, simplifying fertilization procedures, and facilitating farmers to master the use in production. From 1999 to 2001, we conducted trials and demonstrations in our county with a total area of ​​250 mu. After the test production, 283.5 kilograms of low yield per mu, up to 332.6 kilograms, with an average yield of 302.5 kilograms. Compared with the traditional fertilization method in our county, the increase in production per mu is 8%-15%. This set of cultivation techniques is described below. First, the choice of place: should choose to facilitate irrigation and irrigation, more than moderate land, water and fertilizer holding capacity of the land cultivation. Soils with medium or less fertility and poor water and fertility retention are not suitable for this technology. Second, the selection: recommended cultivation of Yueyou 79, Yueyou 5. Third, timely sowing: sowing date should be in early August. Timely sowing allows peanut plants to have a longer period of vegetative growth and accumulate more nutrients, which will facilitate the seizure of high yields. 4. Seed treatment: Peanuts are sunned in the sun for 2 days before shelling, and the shells are peeled on the day before or on the day of planting to increase the germination potential and germination rate of the seeds. Before sowing, remove unsaturated kernels, use full kernels as seeds, and use “Carbendazim†for seed dressing (per 0.2 kg of carbendazim per 100 kg of peanut seed), which is beneficial to peanuts after sowing Emergence and neat seedlings, strong seedlings. V. Selection of Fertilizer and Fertilization Method: After the previous site is plowed, apply 80 kg of compound fertilizer (11.3% of nitrogen, 9% of phosphorus oxide, 11.3% of potassium oxide, and 0.6% of borax) or 9 kg of pure nitrogen according to the formula. , Phosphorus oxide 6 kg, potassium oxide 9 kg, borax 0.5 kg, according to this formula or amount of fertilizer all at once under a uniform application, and then the earthworms loose, flat, you can tiller planting. 6. Reasonable close planting: The wide-row narrow-row planting method is used, that is, 1.76 meters per ditch, 5 rows per plant, 2 seeds per seedling, spacing 0.27 meters, 0.17 meters spacing. One of the advantages of this method is the use of edge-advantages. The field population in the middle and late stages of plant growth is more breathable, the stems and leaves do not conceal premature aging, and the second is sufficient number of basic seedlings. This is an important condition for ensuring high yield and stable production of peanuts. Pay attention to digging the ring ditch, remove water in time. Seventh, in addition to cultivator-free cultivator: Evenly spray the herbicide solution on the same day that peanuts are planted. In addition to cultivating cultivars, there are two points worth noting: 1, after spraying herbicides, there are still a small amount of weeds, should be pulled at the flowering time once; 2, drop needles pod stage, the topsoil is too dry, should be properly irrigated to make the soil moist, It helps to make needles and ensure high yields. 8. Apply black and white ash: Apply 50 jin of black and white ash (30 jin of ash + 20 lbs of quick lime) from the peanut flowering stage to the initial stage of podling. Nine, the application of micro-fertilizer: full flowering period, mu with 15 grams of ammonium molybdate water 50 kg sprayed once, before the fruit 40-50 days before spraying again. 10. Spraying foliar fertilizer: Pay attention to spraying foliar fertilizer to protect the leaves at the late stage of growth of peanuts, promote fruit filling, and increase yield. Per acre with 3 pounds of superphosphate soaked in water for 24 hours to take the liquid +1 kg of urea + 0.3 kg of potassium chloride and 120 kg of water sprayed plants. Once every 7 days, spray twice in succession. XI. Prevention and control of pests and diseases: Prevention of rust and leaf spot disease: After flowering, one of the following pesticides may be used and sprayed alternately two or three times in accordance with the instructions for use of the pesticide. 1 world high; 2 chlorothalonil; 3 colloidal sulfur. Control of Peanut Thrips, Aphids, Rollers, Spodoptera litura: The following pesticides may be used to dilute the water according to the instructions for use of the pesticide. 1 Bataan; 2 Aketai; 3 Imidacloprid. 12. Appropriate harvesting: Yueyou 79 was planted for 115 days during the whole growing period; Yueyou 5 was planted for 110 days during the whole growing period.
