萘乙酸纯品为无色针状晶体,工业品为黄褐色针状晶体,易溶于热水、乙醇、乙酸、丙酮和苯,是一种广谱植物生长调节剂。可用于小麦、水稻增加有效分蘖,提高成穗率,促进籽粒饱满,增产显著。也用于甘薯、棉花增产。用于茄类和瓜类,可防止落花落果和形成无籽果实,还能增强植物抗旱涝、抗盐碱、抗倒伏能力。
操作步骤 (仅供参考):
1、小麦用 20mg/L 药液浸种 10-12h,风干播种,拔节前用 25mg/kg 喷洒 1 次,扬花后用 30mg/kg 药液着重喷剑叶和穗部,可防倒伏,增加结实率。
2、水稻用 10mg/L 药液浸秧 6h,插栽后返青快,茎秆粗壮。
3、棉花盛花期用 10-20mg/L 药液喷植株 2-3 次,间隔 10 天,防蕾铃脱落。
4、甘薯用 10mg/L 药液浸秧苗下部 (3cm) 6h 后栽植,提高成活率增产。
5、番茄、瓜类用 10-30mg/L 药液喷花,防止落花,促进坐果。
6、果树采前 5-21 天,用 5-20mg/L 药液喷洒全株,防止落果。
7、茶、桑、侧柏、柞树、水杉等插条 用 25-500mg/L 药液浸泡扦插枝条基部 (3-5cm) 24h,可促进插条生根,提高成活率。

Pure 1-Naphthaleneacetic acid (NAA) is colorless acicular crystals, while the industrial grade is yellowish-brown acicular crystals. It is soluble in hot water, ethanol, acetic acid, acetone and benzene, and serves as a broad-spectrum plant growth regulator. It can be applied to wheat and rice to increase effective tillers, raise the spike rate, promote grain plumpness and achieve significant yield increase. It also boosts yields of sweet potato and cotton. For solanaceous and melon crops, it prevents flower and fruit drop, induces seedless fruit formation, and enhances plant tolerance to drought, waterlogging, salinity, alkalinity and lodging.
Operating Procedures (For Reference Only):
1. For wheat: Soak seeds in 20 mg/L solution for 10–12 h, air-dry before sowing. Spray once at 25 mg/kg before jointing stage. After anthesis, spray flag leaves and panicles with 30 mg/kg solution to prevent lodging and improve seed setting rate.
2. For rice: Soak rice seedlings in 10 mg/L solution for 6 h. Transplanted seedlings recover rapidly and develop robust stems.
3. For cotton: Spray plants with 10–20 mg/L solution 2–3 times during full blooming stage at an interval of 10 days to prevent boll abscission.
4. For sweet potato: Soak the lower part (3 cm) of sweet potato seedlings in 10 mg/L solution for 6 h before transplanting to improve survival rate and yield.
5. For tomato and melons: Spray flowers with 10–30 mg/L solution to prevent flower drop and promote fruit setting.
6. For fruit trees: Spray the whole plant with 5–20 mg/L solution 5–21 days before harvest to avoid pre-harvest fruit drop.
7. For cuttings of tea, mulberry, oriental arborvitae, oak, metasequoia, etc.: Immerse the base (3–5 cm) of cuttings in 25–500 mg/L solution for 24 h to promote rooting and raise survival rate.
