摘 要: | [目的]研究生物培肥剂培肥秧床对机插秧苗形态特征的影响。[方法]以华粳9号为材料,利用生物培肥剂培肥秧床,对水稻秧苗形态特征进行了分析。[结果]生物培肥剂培肥处理的秧苗株高、茎基宽度、地上部鲜重、地上部干重、叶面积较常规培肥处理分别增加了28.86%、6.01%、7.38%、11.56%、16.34%;而秧苗不定根数、根系长度、根系鲜重、根系干重、根系面积、根系发根力也均比常规培肥处理增加了0.41条/株、4.17%、14.61%、16.77%、14.76%、0.7条/株。[结论]生物培肥剂培肥处理有利于增强秧苗素质,促进根系活力,有利于栽后早发。

Abstract: | [Objective] The aim was to study the effect of biological fertility agents on morphological characteristics of transplanted with machinery. [Method] With Huajing 9 as the tested material,biological fertility agents were used as fertility betterment to study the morphological characteristics. [Results] The plant height,base stem width,fresh weight and dry mater weight above-ground,and leaf area of seedlings fertilized by rapid fertilization increased by 28.86%,6.01%,7.38%,11.56%,and 16.34%. Compared with seedlings conventionally fertilized,meanwhile,adventitious root,root length,root fresh weight,root dry weight,root absorbing area and root growth ability also increased by 0.41 bands/plant,4.17%,14.61%,16.77%,14.76%,0.7 bands/plant. [Conclusion] The quality of seedlings was significantly improved and root activities was improved by biological fertility agents,and was beneficial to advance growth after seeding. |
