Through the experiments of the seedbed cultivation, the influence of rice seedling growth characteristic and phosphorus absorption on the low nutrient soil of available phosphorus that using sturdy-seeding agent which inoculates penicillium of dissolving phosphorus.

通过苗床培养试验，研究了在低有效磷营养土上施用接种解磷青霉菌的壮秧剂对水稻秧苗的生长特性及磷素吸收的影响。

The result indicated that in the low phosphorus condition, using sturdy-seeding agent which inoculates fungi of dissolving phosphorus could obviously improve the plant height, increase fresh and dry biomass of the shoots, root vigor, phosphorus content and P uptake of the shoots. In the five treatments, compared to the blank control groups, the plant height of rice seedling increases 16.81%, fresh biomass 21.28%, dry biomass 12.42%, phosphorus content 31.11% and P uptake 44.03% for the shoots, the results were good. Next was P1 and P4 treatments, especially in the P1 treatment, the dry and fresh biomass, phosphorus content and phosphorus uptake of the roots were highest than any other treatment.

结果表明，在低磷条件下，施用接种解磷菌的壮秧剂可以显著提高水稻秧苗的株高、地上部干、鲜生物量、根系活力、地上部磷含量和磷吸收量，在5个处理中，P2处理水稻秧苗的株高比对照提高16.81%，地上部鲜生物量比对照增加21.28%，地上部干生物量比对照增加12.42%，地上部磷含量比对照提高31.11%，地上部磷素吸收量比对照提高44.03%，表现效果较好，其次是P1和P4处理，其中P1处理的根部干、鲜生物量、根部的磷素含量和磷素吸收量均高于其他处理。

Soil samples were collected from different ecological conditions. More than 70 Streptomyces hygroscopicus strains were isolated from the soil samples. Fermentation centrifugal supernatant of the strains were used as biocontrol agents to bioassay the seedling of rice and barnyard grass and rice pathogens of sheath blightand bakanae. Three strains showed good effects of inhibitingbarnyard grass seedling, the another three strains well inhibited the growth of rice pathogenic fungi.

从国内外不同生态条件下采集的土壤标本中分离到70多个吸水链霉菌，用其发酵离心上清液对水稻、稗草秧苗和稻纹枯病菌、恶苗病菌进行生物测定，结果有3个菌株对稗草根的生长具有较好的抑效果；有3个菌株对水稻病原菌有很好的抑制生长作用。
