The role and use of potassium nitrate fertilizer尿素价格运动中枢可能进一步下移
第2部分
Potassium nitrate is a commonly used fertilizer in agriculture. It has a high cost-effectiveness and good water solubility. It can be evenly and quickly absorbed and utilized by crops during the peak period of crop fertilizer demand, without chemical residues. Potassium nitrate is suitable for vegetables, fruits, flowers and some chlorine-sensitive crops, such as potatoes, strawberries, beans, cabbage, lettuce, peanuts, carrots, onions, blueberries, tobacco, apricots, grapefruits and avocados. So, what are the effects of potassium nitrate? What are the advantages? How to apply it on crops? We explain in detail!8月份以来，尿素期货价格震荡下跌，目前主力2501合约已跌破1,900元/吨。分析人士认为，需求疲软是尿素价格下跌的主要原因。
What are the effects of potassium nitrate?尿素使用注意事项
1. Promote nitrogen and potassium absorption. Potassium nitrate can promote the absorption of nitrogen and potassium by crops, has rooting, promotes flower bud differentiation, and increases crop yields.
徽商期货研究所工业品分析师刘萌萌表示，近期尿素期货价格连续下跌，主要是需求支撑不足。作为下游需求最大组成部分的农产品需求处于淡季，8月份甚至处于需求空档期。工业需求方面，目前复合肥企业正在生产秋肥，目前开工率已从低位回升至中高位，其对尿素原料的需求有所增加。不过，由于复合肥企业本身就处于库存积压状态，企业对原材料的采购以刚性需求为主，收货积极性不高。在出口方面，表现不佳。尽管印度近期发布了新一轮尿素招标计划，但中国货源参与本轮招标的可能性仍不大。此外，目前出口管制并未放松，鼓励内销。
2. Promote photosynthesis. Potassium can promote photosynthesis and promote the synthesis and transportation of carbohydrates.
3. Improve the stress resistance of crops. Potassium nitrate can improve the stress resistance of crops, such as drought and cold resistance, lodging resistance, disease resistance, and prevention and treatment of premature aging.
4. Improve fruit quality. Use during the fruit expansion period can promote fruit expansion, increase fruit sugar and water content, improve fruit quality, increase yield and increase income.
What are the advantages of applying potassium nitrate?
1. Because it is not volatile, it can be applied directly to the soil surface;
2. It is more beneficial to apply nitrate nitrogen to chloride-sensitive crops than ammonium nitrogen, such as citrus, grapes, vegetables, and other crops that are sensitive to chloride ions, because the nitrate nitrogen in potassium nitrate can prevent crops from absorbing chlorine in the soil;
3. Nitrate nitrogen can quickly provide nutrients under any conditions and is suitable for spring, summer, autumn and winter crops;
4. It will not cause salt accumulation in the soil.
