具有矮化、 促熟和抗逆作用的植物生长调节组合物
发明领域
本发明涉及具有矮化、 促熟和抗逆作用的含有天然脱落酸的植物生长 调节组合物, 国际分类号属于 A01N37 I 06。
背景技术
天然脱落酸, 农药通用名为 S—诱抗素 (S-ABA) , 即 (+) -顺, 反-天然脱 落酸, 化学名称: 5- (1,-羟基- 2,, 6,, 6,-三甲基 -4,-氧代- 2,-环己烯 -1, - 基) - 3-甲基- 2-顺 -4 -反 -戊二烯酸, 结构式如下:
Figure imgf000002_0001
S— ABA的化学结构 天然脱落酸 (S- ABA ) 与生长素、 乙烯、 赤霉素和细胞分裂素一起并 列为植物五大类激素。 1963 年天然脱落酸首次由 Addicot 等人从棉花幼 果中提取到。 三十多年来, 各国科学家对其植物生理活性作用进行了广 泛深入的研究, 研究表明, 天然脱落酸是植物的 "抗逆诱导因子", 在植 物生长的各个时期起着重要的生理活性作用, 特别是在诱导植株提高抗 旱、 抗寒、 抗盐碱能力和增强植株自身免疫抗病能力等方面, 具有重要 的作用。
S-ABA ( 1. 0-100ppm ) 对作物具有抗寒、 抗旱作用, 但矮化作用不明 显。 助壮素 (Pix ) ( 10. 0-300ppm) 可矮化植株, 促进座果, 但不会引起 早开花, 早结果。 6-苄氨基嘌呤 (6 BA) ( 1. 0-50ppm) 和萘乙酸 (NAA ) ( 1. 0-50. Oppm) 必须处理植物例如棉花的花器才能促进座果, 叶面喷雾 不明显。
本发明者根据天然脱落酸的植物生理活性作用, 以及其与其它植物生 长调节剂等的相互作用研究, 出人意外地发现, 当釆用抑制型调节剂例 如 S-ABA或 Pix与促进型调节剂例如乙烯利、 萘乙酸或 6- BA组合时, 则 既可以矮化作物如棉花、 黄瓜, 促进座果, 又可以达到早开花、 早结果、 早采收, 且果实品质有明显改善, 若在结果期遇到寒冷、 干旱天气, 则 会发挥抗旱、 抗寒的作用, 于是完成了本发明。
发明内容
本发明的目的是提供一种具有矮化、 促熟和抗逆作用的植物生长调节 组合物, 该组合物含有 A ) 天然脱落酸, B ) 助壮素和 C ) 至少一种选自 下列的促进型植物生长调节剂: 乙烯利、 6—苄氨基嘌呤、 萘乙酸、 芸苔 素内酯、 赤霉素、 乙酰水杨酸、 茉莉酸或茉莉酸甲酯。
完全出人意外的是, 本发明所述的天然脱落酸与多种选自所述植物生 长调节剂的植物生长调节剂的组合对作物的生长调节活性超过预期的加 合作用, 且特别在二个方面提高每种成分的活性范围: 一方面, 天然脱 落酸和其它的植物生长调节剂个自的浓度降低而同时保持良好 '的活性, 另一方面, 该新植物生长调节剂组合还在单个化合物在低浓度下不再有 农业效果的情况下获得良好的植物生长调节水平。
本发明中所述的促进型植物生长调节剂乙烯利、 6—苄氨基嘌呤、 萘 乙酸、 芸苔素内酯、 赤霉素、 乙酰水杨酸、 茉莉酸或茉莉酸甲酯均是已 知的, 且描述于例如 《国外农药品种手册》 (新版合订本), 化工部农药 信息总站; 《新编农药手册》, 农业部农药检定所, 农业出版社, 1989 年; 《新编农药手册》 (续集), 农业部农药检定所, 农业出版社, 1998年。
本发明植物生长调节组合物可以用于棉花、 黄瓜、 水果例如草霉、 葡 萄、 荔枝等。
单用 S- ABA ( 1. 0-lOOppm) 对作物具有抗寒、 抗旱作用, 但矮化作用 不明显。 助壮素 (甲哌啶, Pix ) ( 10. 0-300ppm) 可矮化植株, 促进座果, 但不会引起早开花, 早结果。 而促进型调节剂如 6-苄氨基嘌呤 (6- BA ) ( 1. 0-50ppm ) 和萘乙酸 (腿) ( 1. 0-50. Oppm ) 必须处理植物例如棉花 的花器才能促进座果, 叶面喷雾不明显。 釆用本发明的抑制型调节剂例 如 S- ABA或 Pix与促进型调节剂例如乙烯利、 萘乙酸或 6- BA组合时, 则 既可以矮化作物如棉花、 黄瓜, 促进座果, 又可以达到早开花、 早结果、 早采收, 且果实品质有明显改善, 若在结果期遇到寒冷、 干旱天气, 则 会发挥抗旱、 抗寒的作用。 本发明植物生长调节组合物突破了传统组合 物仅在应用上的增效作用, 抑制型与促进型两种调节剂互相取长补短, 使某些调节剂焕发了应用青春, 既能在逆境条件下增加产量, 又可以不 同程度改善果实的品质。
一般而言, 在本发明组合物使用时, ABA 使用浓度为 1. 0- lOOOppm, 优选为 1. 0-500ppm , 更优选为 1. 0-50. Oppm ; 助壮素使用浓度为 1. 0- 500ppm, 优选为 10. 0-300ppm, 更优选为 50. 0-250ppm; 促进型调节剂使 用浓度为 0. 01-500ppm, 优选为 0. 01-100ppm, 更优选为 1. 0- 50ppm。
一般而言, 在本发明植物生长调节剂中, 天然脱落酸: 助壮素: 促进 型生长调节剂混合比率 (重量比〕 介于 1 : 0. 01-100: 0. 001-10 , 优选介 于 1: 0, 1-100 : 0. 01 - 10之间。
施用剂量可以在相当宽的范围内变化且取决于施用类型 (叶面喷施、 涂抹、 灌根、 注射等); 栽培植物的种类、 植物的生长期、 气候条件等; 和受施用类型和时间控制的其它因素。 通常, 根据本发明的组合物可以 以 0. 01至 2. 50千克活性成分 /公顷的施用剂量。 一般而言, 施用时植物 生长调节组合物的施用剂量不是关键的, 关键的是使用时的天然脱落酸 浓度应保持在 1. 0- lOOOppm之间。

通常方便的是将天然脱落酸和各植物生长调节组分分别加工, 直到施 用前由施用者以所需的混合比率将之组合成 "桶混" 水液形式。
采用本发明植物生长调节组合物处理植物, 可以通过在盛花期受精之 后用喷雾方式处理来完成。
一般而言, 施用时组合物的施用剂量不是关键的, 关键的是使用时的 天然脱落酸浓度应保持在 1. 0-1000ppm, 优选 1. 0-500. Oppm之间。
可以根据本发明使用的活性化合物可以以其原样或也可以是其与其它 活性化合物混合的制剂, 例如与已知的杀菌剂、 杀虫剂和植物养分混合, 由此而拓宽作用谱或防治抗性产生以及治疗植物营养匮乏症。 在许多情 况下, 可以获得增效作用, 即, 混合物的活性超过单独组分的活性。
混合物中共组分的实例是如下物质:
