Description
技术领域
本发明涉及水稻种植技术领域，具体涉及一种直播稻促耐淹生长调控剂及其使用方法。
背景技术
水稻是中国重要的粮食作物之一，稻直播指无需育秧、移栽而直接将种子播于大田的一种栽培方式，水稻直播栽培省去了育秧和移栽环节，具有显著的节本、省工、省力、省秧田、高效的优点，可实现水稻种植的机械化与轻型化，成为缺少劳动力农户的首选。
在我国普遍采用的湿直播栽培模式中，通过直播稻出苗阶段构建田间水层可起到良好的封田防草效果，但往往导致稻种处于长期淹水状态，种子萌发时处于淹水条件下，焖种、烂种和死苗率较高，造成出苗不齐、不匀，或偏稀或偏密，群体结构劣化，生产风险较大。因此，齐苗差、全苗率低、杂草难防控是直播稻产量不高不稳的首要问题。
发明内容
为解决上述技术问题，本发明的目的在于提供一种直播稻促耐淹生长调控剂及其使用方法，该生长调控剂充分利用通过羟丙基纤维素和海藻酸钠两个大分子聚合物之间通过羟基形成氢键，从而形成性能好的混合膜，同时，淀粉经高温溶解在水中，作为种衣剂的粘结剂，含有大量的羟基，与海藻酸钠也会形成氢键作用，提高混合膜的缓释功能，增氧剂提高种子周围的氧含量，无机盐渗调引发，杀菌剂、杀虫剂以及赤霉素、羟甲基壳聚糖生长调节剂的活性成分，可以缓慢释放、持续时间长，促进植物生长、提高作物抗逆能力。
为实现上述目的，本发明的技术方案如下。
本发明的目的之一是提供一种直播稻促耐淹生长调控剂，所述生长调控剂以重量份数计，包括如下原料组分：羟丙基纤维素6～10份、海藻酸钠20～25 份、淀粉10～15份、赤霉素3～5份、羟甲基壳聚糖4～6份、无机盐1～3份、杀菌剂2～5份、杀虫剂2～5份、增氧剂3～5份、水30～45份。
优选的，所述无机盐为KNO3、Al(NO3)3、NaNO3、Na2HPO4、KH2PO4、 MgSO4、NaCl和KCl的多种混合。
优选的，所述杀菌剂为甲霜灵、多菌灵、甲基硫菌灵、拌种灵、井冈霉素、稻瘟净的一种或多种。
优选的，所述杀虫剂为锐劲特、毒死蜱、阿维菌素、乙酰甲胺磷、杀虫单、三唑磷的一种或多种。
优选的，所述增氧剂为过氧化钙、过氧碳酸钠、过氧酰胺的一种或多种。
优选的，由以下重量份的组分制成：羟丙基纤维素8份、海藻酸钠22 份、淀粉12份、赤霉素4份、羟甲基壳聚糖5份、无机盐2份、杀菌剂2 份、杀虫剂2份、过氧化钙3份、水30份。
本发明的目的之二是提供上述直播稻促耐淹生长调控剂的使用方法，其特征在于，包括如下步骤：
S1、按照比称羟丙基纤维素、海藻酸钠、淀粉、赤霉素、羟甲基壳聚糖、无机盐、杀菌剂、杀虫剂、增氧剂和水；
S2、将S1中赤霉素、羟甲基壳聚糖、无机盐、杀菌剂和杀虫剂加入总量一半的水中室温搅拌均匀形成混合物A；
S3、将剩余的水加热至50～60℃，将S1中羟丙基纤维素、海藻酸钠和淀粉加入搅拌均匀得到混合物B，室温冷却后将混合物A再加入混合物B 后，调节pH6.5～7之间，搅拌均匀形成悬浮溶液的生长调控剂；
S4、将S3得到的生长调控剂倒入容器中，将直播稻种子完全浸渍在生长调控剂溶液中，进行搅拌后静置8～15min，然后取出进行晾晒，干燥后进行播种。
优选的，S4中，所述静置的时间为8～15min。
优选的，S4中，所述生长调控剂通过水稀释10～15倍。
优选的，S4中，所述直播稻种子与生长调控剂溶液的体积质量比为 1g:3mL。
本发明与现有技术相比，其有益效果在于：
1、本发明通过羟丙基纤维素和海藻酸钠两个大分子聚合物之间通过羟基形成氢键，可以改善膜的性能，从而形成性能较好的混合膜，同时，淀粉经高温溶解在水中，作为种衣剂的粘结剂，含有大量的羟基，与海藻酸钠也会形成氢键作用，从而可以有效抑制海藻酸钠的大量溶胀，提高其缓释功能，通过海藻酸钠可以在液体状态的混合膜中会有大量气泡，并且在成膜后气泡也不会消失，增加膜的通透性，对水稻种子进行包衣，进而可防止稻种处于长期淹水状态，增氧剂可与水反应缓慢放氧，可提高种子周围的氧含量，起到增氧剂的作用，避免种子萌发时处于淹水条件下造成焖种、烂种；且淀粉以及无机盐在水中逐渐水解也为种子提供丰富的碳源、氮源。
2、通过混合膜内的无机盐小分子在水溶液中均可以解离为相应的离子，种子萌发过程中，可以渗透进入细胞内，改善细胞内的微环境，降低细胞的水势，增加种子在引发过程中水分的吸收量，同时，也能使混合膜的水势保持在一个较低的状态，从而对在萌发时过程中由于种子稻种处于长期淹水状态有一定的缓冲作用。
3、通过混合膜对种子进行包衣，可以使杀菌剂、杀虫剂以及赤霉素、羟甲基壳聚糖生长调节剂的活性成分，可以缓慢释放、持续时间长，能够有效防治苗期的病虫害，并且可以适当缓解缺素症，促进植物生长、提高作物抗逆能力，确保苗齐苗壮、促进幼苗生长，能提高产品产量、改善产品品质。

对比例6
采用清水进行对种子进行浸泡处理。
将实施例1～4及对比例1～5处理的种子进行大田实验，每组种子的数量为500粒，种植前施入基肥，按照每亩施用20千克撒可富，采用随机区组设计，种植方式为湿直播，每组实验田的播种量相同，均匀条播成5行，于 5月10号播种，人工撒播；在播种后保持2～3cm的水层，出苗稳定后褪去水层，正常水分管理。
田间管理：在出苗稳定褪去水层后，分别在水稻的分蘖期和拔节期施氮肥、钾肥和磷肥，其中氮肥、钾肥和磷肥的施用量分别为120kg hm～2的尿素，80kg hm～2的硫酸钾、30kghm～2的钙镁磷肥；待水稻成熟后进行收割；
分别在第15d起统计种子发芽数，以15d内发芽的百分率分别为发芽势和发芽率，其中发芽率(％)＝正常幼苗数/供试种子数*100％；发芽势(％)＝前 10d发芽数/供试种子数*100％；发芽指数为15d的种子发芽数/相对应的种子发芽天数；每个处理随机选取每个实验田的水稻幼苗20株，进行计算平均后的活力指数。
如表1所示，实施例1～4及对比例1～5处理的种子15d后的活力状况，从表1可以看出，经过本发明实施例1～4的生长调控剂浸泡种子后，对芹菜种子发芽势有极显著提高作用，种植10天后的水稻发芽数量明显高于对比例1～5处理的种子，其对比例1～5处理的种子在15d天时才明显增加，其 15d后发芽率达到90％以上，发芽指数达到30％以上，其中实施例1活力指数最高为20.03，比对比例1单一膜形成的生长调控剂高出近一倍；实施例 1～4出苗后苗期的发病率明显下降，可见，混合膜对种子进行包衣，可以使杀菌剂、杀虫剂以及赤霉素、羟甲基壳聚糖生长调节剂的活性成分，可以缓慢释放、持续时间长，能够有效防治苗期的病虫害，并且可以适当缓解缺素症，提高作物抗逆能力，提高了种子的萌发，确保苗齐苗壮、促进幼苗生长。
表1实施例1～4及对比例1～5处理的出苗状况
表2为实施例1～4及对比例1～5得到的直播稻产量的影响，如表2所示，实施例1～4经过本发明的生长调控剂浸泡处理种子后，其结实率在95％以上，远远高于对比例1采用一种成膜剂进行包衣后以及不添加生长调控剂的对比例2水稻种植后的结实率，实施例1～4得到的实际产量在11.3t以上，增加了22.6％，比对比例1增加14％以上，故通过羟丙基纤维素和海藻酸钠两个大分子聚合物之间通过羟基形成氢键，可以改善膜的性能，从而形成性能较好的混合膜，同时，淀粉经高温溶解在水中，作为种衣剂的粘结剂，含有大量的羟基，与海藻酸钠也会形成氢键作用，从而可以有效抑制海藻酸钠的大量溶胀，提高其缓释功能，增加膜的通透性，对水稻种子进行包衣，增氧剂可与水反应缓慢放氧，可提高种子周围的氧含量，起到增氧剂的作用，淀粉以及无机盐在水中逐渐水解也为种子提供丰富的碳源、氮源，可以使杀菌剂、杀虫剂以及赤霉素、羟甲基壳聚糖生长调节剂的活性成分，可以缓慢释放、持续时间长，能够有效防治苗期的病虫害，并且可以适当缓解缺素症，促进植物生长、提高作物抗逆能力，确保苗齐苗壮、促进幼苗生长，能提高产品产量、改善产品品质。
表2实施例1～4及对比例1～5得到的直播稻产量的影响
需要说明的是，本发明中涉及到数值范围的，表示在该数值范围内的任意数值均可行，为了防止赘述，本发明仅描述了的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例做出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本发明范围的所有变更和修改。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
