磷酸二氫鉀的作用
　　Effect of Potassium Dihydrogen Phosphate
　　提高作物的抗性，抗低溫抗倒伏，有在巴西蕉幼苗上做試驗，證明適當(dāng)濃度的磷酸二氫鉀可以提高香蕉苗的抗低溫。
　　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.
　　增強作物抗碰傷和自然腐爛能力，延長貯運期限。
　　Enhance the ability of anti-collision and natural decay of crops and prolong the storage and transportation period.
　　因為磷酸二氫鉀是磷鉀二元復(fù)合肥，所以在果實果實膨大期噴施可起到保果壯果，促進果實膨大，可提高果實的品質(zhì)，增加著色，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.
　　在開花前后噴施：促進花芽分化、增加開花數(shù)、花苞碩壯、壯花保果、提高坐果，還能有效促進根系的生長發(fā)育，促進作物提前成熟。
　　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.
　　同時高純度的磷酸二氫鉀因為水不溶物比較少，因此使用方法多樣，有噴施、沖施灌根、蘸根移栽、浸種拌種、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，對于磷酸二氫鉀是否含氯，要看磷酸二氫鉀中鉀的來源，是氯化鉀還是氫氧化鉀或者其他鉀源決定的。一般，工業(yè)一等品對氯離子含量有限制，而農(nóng)業(yè)標(biāo)準(zhǔn)沒有規(guī)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.
　　磷酸二氫鉀施用范圍：
　　Application range of potassium dihydrogen phosphate:
　　柑橘、西瓜、蘋果、梨、葡萄、山楂、香蕉、芒果、荔枝、龍眼、棗、獼猴桃、草莓、水稻、小麥、玉米、棉花、大豆、花生、絲瓜、西紅柿、豆角、茄子、辣椒、菠菜、韭菜、薯類、食用菌、藥材、花卉、草坪、茶葉、煙草等。
　　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.
　　注意事項：
　　Matters needing attention:
　　高濃度使用磷二的時候，一定要避開高溫時間，一般高溫的季節(jié)不建議高濃度使用。（特別注意）
　　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)
　　宜選在上午10點前，下午4點后噴施。
　　It is advisable to spray it before 10 a.m. and after 4 p.m.
　　磷二可與酸性，中性農(nóng)藥混合施用，增加藥效，不能與堿性物質(zhì)混用。
　　Phosphorus dioxide can be mixed with acidic and neutral pesticides to increase its efficacy, but not with alkaline substances.
　　磷二屬全水溶肥料，遇水即溶，請貯存于陰涼干燥處。開袋未使用完請密封。
　　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.
