摘要
利用中药渣和粉碎稻草为基质代土育秧,探讨中药渣基质的育秧效果。结果表明,不同药渣体积比处理的种子出苗率在93%~98%,成秧率在91%~97%。播种后7 d之内秧苗生长较慢;7 d之后秧苗生长随药渣比例的增加,生长加快。增加育秧基质中药渣比例,提高秧苗素质,表现出苗高更高,叶片数多,假茎宽增大,壮苗指数提高;发根数增多、根系氧化力提高。增加育秧基质中药渣比例可提高水稻秧苗叶绿素和氮素含量。植株中全氮33 mg/g、总糖38 mg/g左右,氮/糖比接近1的秧苗素质最佳。基质比例为药渣70%、稻草10%、红壤粘土20%,培育的秧苗综合素质最好。中药渣是一优质取代土壤培育水稻秧苗的基质。
The effect of substrate of fraditional Chinese medicine residue plus crushed rice straw on cultivation of rice seedlings was expolred.The results showed that the emergence rate of the seeds treated with this substrate was between 93% and 98% and the seedling rate was between 91% and 97%.The seedling growth was slow within 7 days after sowing and the seedling growth quickened with the increase of the proportion of drug residue after 7 days.The seedling quality was improved with the increase of the proportion of traditional Chinese medicine residue in the seedling raising substrate.The expressions were increased seedling height,number of leaves,width of false stem,the index of strong seedlings the number of roots and the oxidation power of roots.The chlorophyll and nitrogen contents of the rice seedlings was increased by the increased proportion of traditional Chinese medicine residue in the raising substrate seedling.The seedlings had the best quality with total nitrogen 33 mg/g,total sugar 38 mg/g and ratio of nitrogen/sugar close to 1.The substrate with the proportion of 70% of traditional Chinese medicine residue,10% of rice straw and 20% of red clay cultivated seedlings of best overall qualitu.The residue of traditional Chinese medicine was a high quality matrix substitute for soil to cultivate rice seedlings.
