The invention discloses a method for improving the substrate of water grass plus peat tissue culture seedlings. The method comprises: mixing the peat: organic fertilizer according to 10:1 and placing it at the bottom 1/2 of the hole tray; wrapping the tissue culture seedlings with water grass and placing it at the top 1/2 of the hole tray. The tissue culture seedlings cultivated by the aquatic grass substrate have the advantages of fast growth, fast growth of new roots and more bacteria. The tissue culture seedlings cultivated by peat substrate were strong, the stem was thick and the price was low. Mixed organic fertilizers of peat provide nutrients for tissue culture seedlings, so that the growth of tissue culture seedlings is strong. According to the characteristics of fertilizer-oriented growth of plants, the mixed organic fertilizer of peat is placed at the bottom of small holes in the tray, which is conducive to the root growth of tissue culture seedlings, but also conducive to the survival of tissue culture seedlings after transplantation in the field. This also saves the usage of water grass and reduces the cost.
【技术实现步骤摘要】
水草加草炭组培苗练苗基质改进方法
本专利技术涉及练苗基质
,尤其是涉及一种水草加草炭组培苗练苗基质改进方法。
技术介绍
组培苗出瓶后苗子非常柔弱,娇嫩,必须要经过驯化练苗过程进行强壮组培苗,组培苗得以适应自然环境条件生长。现有练苗基质主要有两种模式:一种草炭混合其他保水透气材料的基质,另外一种是纯水草的基质。驯化练苗过程是组培苗进入自然环境必备的一个过程,过程中间组培苗会有损耗,当然成活率越高越好。这两种模式都有弊端:一种草炭混合其他保水透气材料的基质,练苗中的缺点:导致组培苗低矮,生长缓慢;生长新根的速度慢,数量少;基质中易带杂菌,导致组培苗也易感染杂菌。一种是纯水草的基质,练苗中的缺点:组培苗虚弱,徒长,茎细弱;成本高。
技术实现思路
本专利技术的目的就是为了解决上述问题,提供一种水草加草炭组培苗练苗基质改进方法,其大大提高了组培苗成活率,这样驯化后的组培苗根系好,苗壮,移栽大田成活率高。为解决上述技术问题,本专利技术提供了一种水草加草炭组培苗练苗基质改进方法,该方法为:将草炭:有机肥按照10:1混合后置于穴盘小穴底部1/2处;用水草将组培苗包裹起来而置于穴盘小穴上部1/2处。与现有技术相比,本专利技术提供的水草加草炭组培苗练苗基质改进方法结合现有的两种基质混合使用,并且加以改进。水草做组培苗驯化练苗的基质的优点是:组培苗高,生长快;生长新根的速度快,数量多;水草基质因做过高温脱水处理,带杂菌少,组培苗不易感染杂菌。但是水草导致组培苗虚弱,徒长,茎细弱。并且成本高。草炭混合其他保水透气材料的基质做组培苗驯化练苗的基质的优点,生长慢,苗壮,茎粗;成本低 ...
