Vegetable Potato Fertilization Points
The main use of potatoes is in the form of vegetables. The edible organs are tubers and their starch content is high. Fertilization is generally dominated by organic fertilizers, with the appropriate application of nitrogen, phosphorus and potassium fertilizers. At the same time, the application of trace element fertilizers can also increase production and improve quality. Potato is a potassium-promoting crop. The application of potash fertilizer has a significant effect on the yield increase, and potassium sulfate is more effective. Experiments show that the effects of nitrogen and potassium on potato yield show a clear interaction. In addition, boron and magnesium fertilizers have significant effect on the increase of potato yield. The effective boron content of 0.6 mg/kg to 0.66 mg/kg in soil can be used as a critical range of potential boron deficiency in potato soil. Mushi 3 kg of magnesium sulfate can reduce browning symptoms in the stem. 1. Fertilizer application amount is 300 kg to 500 kg of organic fertilizer, 6 kg to 7 kg of pure nitrogen, 4.5 kg to 5.5 kg of phosphorus pentanitrate, and 8 kg to 9 kg of potassium oxide. 2. During the fertilization period, nitrogen fertilizer should be applied in stages, and the combination of base fertilizer, seed fertilizer and topdressing fertilizer should be used to meet the requirements of nitrogen for each period of potato. Phosphate fertilizers are generally mostly used as base fertilizers or seed fertilizers. If topdressing is applied deeper, the fertilizer efficiency is still not high. Potash fertilizer application period can be used as a base fertilizer, but also in the late Yenan topdressing. 3. Fertilization methods Basal fertilizers use organic fertilizers from 300 kg to 500 kg and compound fertilizers from 15 kg to 20 kg. The specific method is: In autumn, the organic fertilizer and chemical fertilizer are sprinkled on the ground before the autumn tillage, and then the tiller is ploughed to fully mix the fertilizer and the soil. The second is spring application, which is applied to the surface before the spring plowing, and then tilled. The third is to apply fertilizer and apply it to the sowing ditch at the time of sowing. Fertilizers should be used in conjunction with the potato growth period. The time is optional at the seedling stage, bud stage and early and long-term. Each top dressing should use different fertilizers, and nitrogen, phosphorus and potassium should be used in combination. The general seedling stage and bud stage can be topdressed with nitrogenous fertilizers and phosphate fertilizers. 25 kg of ammonium sulfate and 20 kg of diammonium phosphate and 20 kg of potassium sulfate are used per acre. In the bud stage and early flowering stage, phosphate fertilizer and potash fertilizer were applied, and 10 kg of diammonium phosphate and 15 kg of potassium sulfate were used. Never use nitrogen fertilizer after the flowering period, so as not to cause stems and leaves to grow long. Affects the transport of nutrients to tubers. The borax-magnesium fertilizer and other medium- and micro-fertilizers are generally sprayed on the leaves at the beginning of flowering, once every 7 days, three times in a row. Concentration in the borax 0.05%, 0.5% magnesium sulfate. Erythritol For Chocolate,Zerose Erythritol,Lakanto Erythritol,Pure Erythritol Powder Ningxia Eppen Biotec CO.,LTD , https://www.nxeppen.com
