  • Thidiazuron is a new type of high-efficiency plant growth regulator. It has been found to have strong biological activity, and its ability to induce plant cell division and callus is more than a thousand times higher than that of general cytokinins.

At the same time, it can also improve the drought resistance and cold resistance of crops, and alleviate the symptoms of crop diseases and insect pests, phytotoxicity, fertilizer damage and freezing damage. It has no residue in plants, no pollution to the environment, no safety to humans and animals, no poison to bees, birds, natural enemies, silkworms and fishes. Because of its high safety, it has broad application prospects in agricultural production.
  • Moss plant growth regulators belong to cytokinins.

Description

一种植物生长调节组合物 技术领域
本发明属于农业植物保护领域，特别是涉及一种具有改进性能的植物生长调节剂的组合物，具体地说是涉及一种包含噻苯隆和嘌呤类植物生长调节剂的组合物。
背景技术
噻苯隆(thidiazuron)是一种新型高效植物生长调节剂，科学研究发现它具有很强的生物活性，其诱导植物细胞分裂、愈伤组织的能力比一般细胞分裂素高一千倍以上；能延缓植物衰老，增强其抗逆性，促进植物的光合作用；还能提高作物产量，改善产物品质，并能明显改善品质，增加糖份和果实重量，增加花卉艳丽。同时还能提高作物的抗旱，抗寒能力，缓解作物遭受病虫害，药害，肥害，冻害的症状。并且在植物体内无残留，对环境无污染，对人、畜安全，对蜂、鸟、天敌、蚕、鱼无毒；由于它的安全性比较高,所以在农业生产上的应用前景广阔。
嘌呤类植物生长调节剂属于细胞分裂素。一般认为细胞分裂素是在植物的根尖合成，然后通过木质部运转到地上部，促进植株生长，细胞分裂素除了促进细胞伸长外，更重要是促进细胞分裂.是植物组织分化的物质基础之一。这类化合物对植物的生长发育起重要作用，不仅可以促进核酸和蛋白质的合成，而且能抑制核酸和蛋白质的分解，从而起到促进植物细胞分裂和延缓植物衰老的作用。目前现有公开的嘌呤类植物生长调节剂的衍生物较多，如糠氨基嘌呤、烯腺嘌呤、羟烯腺嘌呤、苄氨基嘌呤等，这些衍生物在针对具体的靶标作物时，相互间的活性差异较大。

通过实验发明人发现，噻苯隆与糠氨基嘌呤之间具有很好协同提升作用，噻苯隆与糠氨基嘌呤混配在不同配比下，相对噻苯隆、糠氨基嘌呤单剂，以及清水对照，对玉米的生长调节作用明显，主要表现在：1、可有效增加玉米的株径，提升植株上下营养传导能力，而且通过促进株径，可以提高玉米的抗倒伏性能；2、噻苯隆具有很好地激发植株内在抗病、防病生理机制，对玉米炭疽病具有很好的预防作用，而属于植物内在生长激素，可以增强作物的抗病抗逆能力，噻苯隆与糠氨基嘌呤之间共同施用具有良好的协同作用，从上表分析可以看出，噻苯隆与糠氨基嘌呤之间协同作用对玉米炭疽病的预防效果相对于单剂及清水对照，具有很好预防效果；3、噻苯隆与糠氨基嘌呤之间的协同作用，可以有效地的增加玉米叶片的单位叶片面积，增强光合作用；4、由于玉米生长前期噻苯隆与糠氨基嘌呤的协同作用，促进了玉米植株的营养传导、抗病抗逆，在玉米成熟期，对玉米的千粒重以及单位亩产有显著的提升作用。
2、噻苯隆与羟烯腺嘌呤复配对葡萄(品种：玫瑰香)生长调节综合测定试验
将噻苯隆与羟烯腺嘌呤用丙酮按照一定浓度稀释，分别在葡萄开花前10天和葡萄盛花后12天进行两次喷雾，在田间测定各个配比对作物生长的影响，包括对坐果率、抗病情况、果实百粒重，以及产量情况等进行综合评价。
座果率通过标记各个葡萄植株的花蕾数，来计算座果数量。
座果率＝果粒数/花蕾数*100％
穗粒提高率＝(清水对照穗粒数量-药剂处理的穗粒数量)/清水对照穗粒数量*100％
穗粒重量率＝(清水对照百粒重量-药剂处理的百粒重量)/清水对照百粒重量*100％
病害预防控制率＝(清水对照发病指数-处理后发病指数)/清水对照的发病指数*100％
增产量＝(药剂处理的每穗重量-清水对照的每穗重量)/药剂处理的每穗重量*100％

注：表格中“噻”为“噻苯隆”的缩写，“羟”为“羟烯腺嘌呤”缩写。
从上表实验数据分析表明(表2)，1、噻苯隆与羟烯腺嘌呤复配对葡萄的座果率有显著的提升作用；2、由于座果率的提升，葡萄后期生长的穗粒数也有相应的提升作用；3、由于噻苯隆、羟烯腺嘌呤均属于植物内在激素，两者混配后可以使葡萄叶片更厚实，增强光合作用，促进葡萄内在营养的传导作用，提高葡萄的糖分和水分，因此对葡萄的籽粒有显著的提升作用，籽粒重量相应提高，从而显著提高葡萄的单位产量。
