在印度马铃薯的种植面积达80万公顷,成为最重要的经济作物之一。其生产潜力比其它大多数大田作物都大。马铃薯钾素带走量在山区每公顷高达193公斤,而在平原则为148公斤。每吨块茎带走的钾(K)约为11公斤。钾在块茎的累积量平均为2公斤/公顷·日,因此,必须施用钾肥,才能获得最佳的马铃薯产量。马铃薯施钾,产投比约达20,这表明马铃薯施钾是极获益的。马铃薯施钾的效果马铃薯施钾的效果因土壤类型、季节、品种、肥料种类及其施用时间和方法而异。本研
Potato planting in India reached 800,000 hectares, making it one of the most important cash crops. Its potential for production is greater than most other field crops. The amount of potash taken away by potassium is 193 kilograms per hectare in the mountains and 148 kilograms in the plain. Potassium (K) removed per ton of tubers is about 11 kg. The accumulation of potassium in tubers averaged 2 kg / ha / day, so potash fertilizer had to be applied in order to obtain the best potato yield. Potato potassium, production ratio of about 20, indicating that potassium is extremely beneficial to potatoes. Effect of potassium on potatoes The effect of potash on potatoes varies according to soil type, season, variety, type of fertilizer and time and method of application. This research
