High-yield autumn peanut production technology
In the village of Hemian in Qingshan Management District, Dianbai County, the average annual output of peanuts exceeds 250 kilograms for the tenth year and 360 kilograms for the highest output. The main techniques for the production of high-yielding autumn peanuts are: 1. To implement proper sowing. If the planting is too early and the rainfall is heavy in the early stage, the plants will be prone to excessive growth and diseases and pests will occur. In particular, the occurrence of witches'broom disease will be detrimental to flowering and scarring. If they are too late, they will be affected by the low-temperature drought in the later period and the fruit development will be poor and the yield will be low. During the period from the beginning of autumn to the summer heat, light and warm rain are more suitable for the growth of peanuts. 2. Appropriate density broadcast to ensure full seedlings. During the sowing period of autumn peanuts, due to the effects of high temperature and heavy rain, the general emergence rate is only 70% or 80%. With sowing, the rain is getting less and the temperature is getting lower, which is not conducive to high yields. Therefore, it is necessary to appropriately increase the planting density. It is advisable to broadcast 2-22,000 seedlings per acre. At the same time, the seedlings should also be checked in time to ensure the seedlings. 3. Apply basal fertilizer and apply fertilizer scientifically. In view of the short growing period of the vegetative period of autumn peanuts, the seeds are sown for 20 days. Therefore, it is necessary to apply sufficient basal fertilizer and apply fertilizer scientifically. Basal fertilizer is generally 40 mu for high-quality soil miscellaneous fertilizer, 25 kg for peanut bran, 25 kg for superphosphate, and 10 grams for plant ash. Three kg of urea should be added as base fertilizer before planting. Top dressing application, timely and appropriate, when the seedlings grow 3-4 pieces of seedlings, combined with cultivator, 5 kg of urea per acre, the best flowering lime mu or 30 kg of black and white ash, promote seedling length and robustness, enhance resistance Disease power. In the late period, it is often affected by low temperature and drought. In addition, rootless fertilization should be conducted in time to prevent early corpses. 4. Strengthen management and prevent pests and diseases in a timely manner. Pre-rainy, easy to be baptized, late flowering, crusting will be affected by low temperature and dry weather, therefore, we must strengthen management as soon as possible, open a good "three levels" drainage irrigation ditch, to prevent drought and damage, is a good kind of autumn peanut must pay attention Grasp the key and links. At the same time, we must also timely prevent and treat diseases, insect pests and floating dust. We must control the pesticides in time and use 600 times malathion or 800 times the liquid of trichlorfon to kill, with good results. In the mid-term, there will be locusts and Spodoptera littoralis, which can be sprayed with 800 times the enemy insects. The effect is very good. Leaf spot and rust should be promptly used 200 times more Bordeaux mixture, 200 times colloidal sulphur or 800 times chlorothalonil and other alternately used, spraying once every 10 days for 3-4 times.
