磷酸二氢钾的作用
　　Effect of Potassium Dihydrogen Phosphate
　　提高作物的抗性，抗低温抗倒伏，有在巴西蕉幼苗上做试验，证明适当浓度的磷酸二氢钾可以提高香蕉苗的抗低温。
　　In order to improve crop resistance, low temperature resistance and lodging resistance, experiments were carried out on Brazilian banana seedlings, which showed that appropriate concentration of potassium dihydrogen phosphate could improve the low temperature resistance of banana seedlings.
　　增强作物抗碰伤和自然腐烂能力，延长贮运期限。
　　Enhance the ability of anti-collision and natural decay of crops and prolong the storage and transportation period.
　　因为磷酸二氢钾是磷钾二元复合肥，所以在果实果实膨大期喷施可起到保果壮果，促进果实膨大，可提高果实的品质，增加着色，改善口味等。
　　Because potassium dihydrogen phosphate is a compound fertilizer of phosphorus and potassium, spraying in the period of fruit enlargement can protect and strengthen fruit, promote fruit enlargement, improve fruit quality, increase coloring, improve taste and so on.
　　在开花前后喷施：促进花芽分化、增加开花数、花苞硕壮、壮花保果、提高坐果，还能有效促进根系的生长发育，促进作物提前成熟。
　　Spraying before and after flowering can promote flower bud differentiation, increase flowering number, strong bud, strengthen flower and fruit, improve fruit setting, and effectively promote root growth and development, and promote early ripening of crops.
　　同时高纯度的磷酸二氢钾因为水不溶物比较少，因此使用方法多样，有喷施、冲施灌根、蘸根移栽、浸种拌种、基施。
　　At the same time, high-purity potassium dihydrogen phosphate is used in a variety of ways, such as spraying, irrigating, transplanting with dipping roots, soaking seeds, mixing seeds and basal application.
　　后，对于磷酸二氢钾是否含氯，要看磷酸二氢钾中钾的来源，是氯化钾还是氢氧化钾或者其他钾源决定的。一般，工业一等品对氯离子含量有限制，而农业标准没有规定。

　　Finally, whether potassium dihydrogen phosphate contains chlorine depends on whether the source of potassium dihydrogen phosphate is potassium chloride or potassium hydroxide or other potassium sources. Generally, the content of chloride ion in industrial first-class products is limited, but the agricultural standards are not stipulated.
　　磷酸二氢钾施用范围：
　　Application range of potassium dihydrogen phosphate:
　　柑橘、西瓜、苹果、梨、葡萄、山楂、香蕉、芒果、荔枝、龙眼、枣、猕猴桃、草莓、水稻、小麦、玉米、棉花、大豆、花生、丝瓜、西红柿、豆角、茄子、辣椒、菠菜、韭菜、薯类、食用菌、药材、花卉、草坪、茶叶、烟草等。
　　Citrus, watermelon, apple, pear, grape, hawthorn, banana, mango, litchi, longan, date, kiwifruit, strawberry, rice, wheat, corn, cotton, soybean, peanut, luffa, tomato, bean, eggplant, pepper, spinach, leek, potatoes, edible fungi, medicinal materials, flowers, lawn, tea, tobacco, etc.
　　注意事项：
　　Matters needing attention:
　　高浓度使用磷二的时候，一定要避开高温时间，一般高温的季节不建议高浓度使用。（特别注意）
　　When using phosphorus dioxide in high concentration, we must avoid high temperature time. In general, high concentration is not recommended in high temperature season. (Special attention)
　　宜选在上午10点前，下午4点后喷施。
　　It is advisable to spray it before 10 a.m. and after 4 p.m.
　　磷二可与酸性，中性农药混合施用，增加药效，不能与碱性物质混用。
　　Phosphorus dioxide can be mixed with acidic and neutral pesticides to increase its efficacy, but not with alkaline substances.
　　磷二属全水溶肥料，遇水即溶，请贮存于阴凉干燥处。开袋未使用完请密封。
　　Phosphorus 2 is a water-soluble fertilizer. It dissolves in water. Please store it in a cool and dry place. Please seal the bags when they are not used.
