- 摘要:
- 为了研究不同难溶性磷（钙磷，铝磷和铁磷）与大豆根系生长的关系，以田间筛选试验为基础，采用室内砂培与水培相结合的栽培方法，分别对磷高效基因型（东农44和东大1号）和磷低效基因型（黑河13和黑河24）大豆苗期根系生长进行比较。结果表明：4个基因型大豆利用难溶性磷酸盐的能力存在显著差异。难溶性磷源条件下，各基因型大豆的根干重、根冠比、总根长、根总表面积比对照处理均有显著增加，而根系全磷浓度、磷含量和平均半径均减小。磷高效基因型大豆在各处理下的根长和根表面积均大于磷低效基因型，但磷高效基因型部分性状的适应性未表现出优势。
- Abstract:
- Based on previous field experiment，two P-efficient soybean genotypes(Dongnong 44 and Dongda 1)and two P-inefficient soybean genotypes(Heihe 13 and Heihe 24)were selected as materials to investigate the relationship between root growth and insoluble phosphate using sand culture and water culture.The results showed that there was significant difference among the ability to use insoluble phosphate for the four soybean genotypes.Compared with control，under the condition of Al-P，Ca-P and Fe-P treatment，the root dry weight，the root/shoot ratio，total length and surface area per plant of root system for the four soybean genotypes increased evidently，while the root P concentration，root P uptake and average root radius all decreased.Under different treatment，the root length and surface area of P-efficient soybean genotypes was greater than that of P-inefficient soybean genotypes，but the adaptability of some traits in P-efficient soybean genotypes did not had advantages.
