Peanut adopts a new technique of mulching and mulching, which has the advantages of early sowing, increasing temperature and moisturizing, preserving drought resistance, improving soil physical and chemical properties, inhibiting weeds, preventing cold and cold damage, promoting early seedlings, early flowering, multiple flowers, increasing fruit production, and mentioning the morning market. advantage. According to the survey, cultivating 667 square meters of peanut film can produce more than 400kg of fresh fruit, and the high-yield field can reach 500kg. It will be listed at the end of June and early July, and the output value of 667 square meters will be more than 2,000 yuan. In the production of plastic film peanuts, the "three-advantage, three-prevention and one-time" high-yield and high-efficiency cultivation techniques are implemented, ie, the varieties are optimized, sowing is optimized, fertilizer is optimized, and measures are taken to prevent leggy, prevent premature senescence, prevent pests, and timely harvest. To achieve the purpose of increasing production gains, the specific technical measures are: First, to optimize varieties, peanut varieties with high quality and high yield should use plants that are robust, strong seedlings, resistant to disease, not premature aging, early-maturing large-grained or medium-maturing kernels, and compact plant types.èš Concentration, great potential for yield increase, and high product quality. Such as Taihua No. 2, Tianfu No. 3 and so on. Second, to optimize sowing, the whole seedlings seedlings should be sun-dried seeds for 2-3 days before sowing, in order to enhance seed coat permeability, enhance seed water absorption capacity, promote seed germination, increase seedling rate. The sowing time should be kept in the cold tail warmer sowing in mid-March. In order to make full use of the pre-fruiting morning market, the planting density must be increased. The general row spacing is 33cm, the hole distance is 20-25cm, and each 10,000 square meters is about 10,000 holes. Each hole is seeded with 2 kernels, and about 20,000 basic seedlings per 667 square meters. Immediately after sowing, it is well covered and pressured to improve the ground temperature, prompting the emergence of seedlings and the emergence of whole seedlings. Third, optimize the fertilization, strengthen the plastic film Peanut should choose a deep layer of soil, loose and fertile soil texture, water retention and fertilizer, breathable winter fields, winter vegetable fields or within two years of Ginkgo leaf interplanting can also be. Combined application of basal fertilizer when ploughing, the main organic fertilizer, coupled with the application of nitrogen, phosphorus, potassium and other fast-acting fertilizer. When site preparation, 667 square meters of methyl isophosphorus O.25kg of water, 5kg of mixed fine soil, 20kg were evenly applied to prevent overwintering. And a good set of ditch, so that energy can be discharged, drought irrigation. Plastic film cultivating peanuts generally emerge in about 15 days, so that after the seedlings are excavated, they must use a knife to cut a triangular mouth, help the seedlings to produce a film, prevent high temperature burning, and lack of basal fertilizer. To use 0.2% urea or potassium dihydrogen phosphate to spray fertilizer out of roots, and promote seedling growth, so that early flowering needles, more flowering needles together, knot early. Fourth, to prevent leggy, high control and promote the strong can be used in peanut cultivation B (9), paclobutrazol and other plant growth regulators, control the stalk above ground length, and promote reproductive growth. In the flowering period, peanuts that grow too busy are sprayed with B (9) paclobutrazol 50g water 50kg per 667 square meters to control high growth, postpone the seal period and reduce shading. Fifth, prevent premature aging and delay the functional period in production. After entering the full-fruit period, the leaf area and photosynthetic productivity drop sharply at the same time, dry matter accumulation dropped to a very low level, and premature aging appeared. Preventing the premature decline of root and leaf in later period, maintaining the vigorous metabolism of plants, especially maintaining the photosynthetic function in the later period is very important. The main management measures are: 1. Strengthen late water management. In the event of drought or waterlogging, roots are susceptible to senescence, causing leaf loss, stem failure, such as field soil moisture below the maximum water holding capacity of 40%, should be timely watering full fruit water, prevent premature plant water shortage. In the event of continuous rain, soil moisture in the field when the water capacity is greater than 70%, should pay attention to drainage and anti-staining. 2. Foliar spray fertilizer is applied at the beginning of the fruiting stage to the full fruit stage. Per 667m2 is sprayed with 50kg of a mixture containing 0.2% potassium dihydrogen phosphate and 1%-2% urea, sprayed every 7-10 days. Once, a total of 2-3 sprays can achieve leaf protection and extend the functional period. Sixth, disease prevention and treatment, and promote the recovery of the main diseases of the mulching peanuts include bacterial wilt, leaf spot, and rust. The main insect pests are cockroaches, aphids, and Spodoptera litura, and they should be focused on preventing and controlling insect pests. Governance, rule early rule of small. Control methods: In addition to strengthening field management, promoting robust growth of peanuts, and enhancing disease resistance, 0.25 kg carbendazim can be used to mix 25 kg of peanut seed before sowing to prevent seed borne pathogens. Rust and leaf spot can be found in peanut growth. In the later stage, combined with extra-root fertilizer application, 75% chlorothalonil can be used alternately with 1% equivalent Bordeaux mixture; when maggots and Spodoptera litura occur, they can be sprayed with 40% dimethoate emulsion or 50% methamidophos; In the initial stage, water pouring with 500 kg of water was controlled by O.25 kg of methylisophos- phorus, and the effect of splashing before the rain was better. VII. Harvesting in Time, Increasing Benefits The general growth period of groundnut peanuts is about 90 days, and the full fruit rate can reach more than 85%. At this time, it should be timely harvested and listed in order to increase the efficiency. The local general can be from late June to early July. Harvested and listed.
