In order to increase the profitability of peanut cultivation and improve the quality of peanut products, it meets the requirements of modern markets for food quality and safety. Specially introduced peanut pollution-free cultivation techniques for the cultivation and application of peanut growers. First, choose to broadcast 1. The sandy loam with deep soil and fertile soil should be used. 2. Select high quality and excellent peanut varieties. The relatively infertile plots were planted with small peanuts and blue flowers on the 6th, and the large peanut Huayu No.33 was planted on the fertile plots. 3. Within one month before sowing, the sunny day was selected to be shelled for two days at noon. To sterilize and prevent diseases, enhance disease resistance, break seed dormancy and increase seed germination rate. 4. Within one or two days before sowing, use 30% chlorpyrifos capsules to prevent seedlings in the whole growth period, 500 grams per mu, 25 kg for peanuts, and 60-80 for the severely dead land. Mice seed dressing, anti-dead effect is obvious. Second, fertilization ridge 1. The application of fertilizers should be combined with the application of organic fertilizers and inorganic fertilizers. Organic fertilizers are not only comprehensive in nutrition, but also can improve soil structure and improve the quality of peanuts. Mu can use 100 kg of high-nitrogen and high-potassium compound fertilizer, and can be used in combination with high-quality bio-organic fertilizer 80-160 kg, evenly mixed and distributed along the ditch. 2. Set up a ridge in the ground before mid-April, which can be ridged mechanically or by cattle. The four ploughs are ridged and the fertilizer is evenly distributed in the middle two furrows. The ridge distance is 85-90 centimeters, and the ridge roof is 40-50 centimeters wide. The height of peanut ridges should be adapted to the local conditions, generally 15-20 centimeters. The dry and thin ridge areas should be lower, and the grazing land should be higher. In previous years, there were many mountain peasants from the peanut ridge is too high, is not conducive to drought resistance peanuts, should pay particular attention to the use of iron floor flat, ridge height of about 15 cm. There are also many peanut ridges that form a ridge, which is not conducive to drought resistance of peanut seedlings, and it is not conducive to the lowering of peanuts. Special attention should be paid to the top of ridges. Third, sowing film 1. In late April in early May, after looting and sowing seeds, it can be used mechanically or artificially, with one ridge and two rows, with a depth of 3-5 cm. 2. After sowing, spray herbicides such as dole and cable to prevent weeds. Acetochlor used to change the habit, acetochlor side effects, high residue. 3. Mu is covered with 5 kg of high quality plastic film. IV. Field Management during Emergence 1. Strengthen field management after lamination. Breaking the membrane in time to emerge the seedlings, promptly tighten the membrane at the cracked place, tightly cover the membrane tilted by the spring breeze, and prevent livestock from trampling and breaking the membrane. At the same time, use a shovel to remove the weeds from the ridges and nets, or use soil pressure to eliminate netgrass. You mustn’t carelessly or think that you have sprayed herbicide and everything will be all right. 2. After the seedling membrane has been unearthed, the membrane surrounding the seedlings should be tightly packed with soil to prevent runaway temperatures and facilitate seedling growth. In past years, many farmers had paid special attention to this issue, either disapprovingly or using excuses as a favor. The wind blows the membrane and it is easy to shake the seedlings. At the same time, it is very helpful to use a soil shovel to raise the seedlings to support the seedlings. 3. Pay attention to the lack of seedling replanting at the late stage of emergence. 4 before and after flowering should pay attention to the prevention and control of aphids, timely use high efficiency and low toxicity pesticide imidacloprid, acetamiprid eradication. V. Flowering and dropping period field management 1. Attention should be paid to the control of cotton bollworm by using highly effective and low-toxic pyrethroids, methacrylate, abamectin, and other pesticides. 2. Completely eliminate the net weeds. 3. In case of special drought should try to water. 4. At the end of the lower needle, when the plants are more than 40 centimeters high, there is a trend of appetite, which can be used to ensure full strength and control. Mu 40 grams, watered 60 pounds of foliar spray. 5. Prevent disease and protect leaves, use 80% mancozeb 500 times and 50% carbendazim 1000 times mixed spray, or use difenoconazole, copper sulfate calcium and other drugs to spray once every 10-15 days, depending on Development can be sprayed two or three times. Sixth, fruit ripening period management 1. spray fertilizer to protect the top leaves. After the peanut is in the pod-setting stage, due to energy transformation, the stem and leaf nutrients do not make up, the base leaves gradually fall off, and only the parietal lobe maintains vitality of the whole plant. Therefore, foliar fertilizer should be sprayed to protect the parietal lobe. Can spray 0.5% potassium dihydrogen phosphate or 1% urea and 3% superphosphate water clarifier, 7-10 days, sprayed 2-3 times. 2. Drainage and filling increase fruit. When there is too much autumn rain, drainage should be taken care of to prevent rotting. If it is too dry and the soil water content is below 40%, it should be watered, which is very beneficial to the increase of production. Seven, timely harvest safe storage It is generally believed that the growth of plants in the shoots is stagnant, the leaves in the lower middle part fall off, and the movement of the upper leaves at night is not sensitive or disappears at night, which is a sign of peanut maturation. In addition, we should mainly look at the fullness of the pods. According to the phenophase of different ripeness, check that most pods are full. If it is not harvested in time, the kernels will turn yellowish-brown in color, and the oil content will decrease, fruit drop, and rotten fruit will increase, which will lead to high yield. Should be selected sunny harvest in time, dried, stored fruit moisture content decreased to 10% or less. At this point, the seed coat is easy to fall off, and the biting seeds have crunchy sounds, which can be safely stored in storage.
