Description

一种海藻酸包膜种衣剂及其制备方法
技术领域
本发明属于种子包衣剂领域，具体地说涉及一种海藻酸包膜种衣剂及其制 备方法。
背景技术
种子包衣是指利用粘着剂或成膜剂，用特定的种子包衣机，将杀菌剂、杀 虫剂、微肥、植物生长调节剂、着色剂或填充剂等非种子材料，包裹在种子外 面，以达到种子成球形或者基本保持原有形状，提高抗逆性、抗病性，加快发 芽，促进成苗，增加产量，提高质量的一项种子技术。种衣剂能迅速固化成膜， 因而不易脱落。用种衣剂包过的种子播种后，能迅速吸水膨胀。随着种子内胚 胎的逐渐发育以及幼苗的不断生长，种衣剂将含有的各种有效成分缓慢地释放， 被种子幼苗逐步吸收到体内，或缓慢释放到种子附件的土壤中，从而达到防治 苗期病虫害、促进作物生长发育、提高作物产量的目的。种子包衣已被列为我 国重点推广的农业技术项目。
同时，随着我国逐步向海洋进军，海洋中的大量生物逐渐的被人类所认识 并逐渐利用，海藻是海洋中数量巨大的一种植物，其含有的海藻酸具有激植物 体内防御酶***活性，增强作物抗干旱、寒冷、盐碱等多种抗逆能力；均衡调 节植物生长，促进花芽分化，提高座果率，减少落果、裂果；促进植物根系发 育，提高对土壤养分、水分的吸收利用；增加叶绿素含量，提高光合作用效率， 大幅度提高产量，改善品质。海藻酸对种苗的初期发育和分化具有重要作用， 因此，将海藻酸用作包衣剂的一种成分对种苗初期的生长具有重要作用。
发明内容
针对现有技术的种种不足，现提出一种含有海藻酸的种衣剂，能够有效提 高种子发育初期耐寒抗病抗旱的能力，有效提高种子的成活率，有效保证种苗 的后续生长。

优选地，所述保水剂包括但不限于吸水树脂。
优选地，所述杀虫剂包括但不限于吡虫啉、***磷、灭多威。
优选地，所述杀菌剂包括但不限于50％多菌灵和/或75％的百菌清可湿性粉。
优选地，所述生根剂包括但不限于萘乙酸生根粉。

优选地，所述警戒性染料包括但不限于胭脂红、酸性大红或玫瑰红。
另，本发明还提供一种海藻酸包膜种衣剂的制备方法，将海藻酸、黄土、 保水剂、杀虫剂、杀菌剂，生根剂、水与种子按照比例添加混合，通过药用包 衣锅进行丸化包衣，再添加驱避剂，最后添加警戒性染料进行丸化包衣。
本发明的有益效果是：
1、海藻酸能够刺激植物体内防御酶***活性，增强作物抗干旱、寒冷、盐 碱等多种抗逆能力，促进植物根系发育，提高对土壤养分、水分的吸收利用， 有效提高种子的成活率。
2、本发明包含杀虫剂和杀菌剂能够防止害虫危害幼苗或土壤中的种子，并 有效的防止病菌侵害，保证种苗成长，提高作物产量。
3、本发明制得的种子，在种衣的外层包覆有驱避剂或警戒性染料，能够有 效的防止鸟类的破坏。
