Abstract
本試驗分田間及盆栽兩部份，其目的在探求適於琉球大豆根瘤菌，以供接種而增加其產量，特再以自琉球大豆本身分離出之根瘤菌重作試驗，以觀察其增產效果。可得結論如下：
(1) 由本試驗結果，確定琉球大豆根瘤，非為一般大豆之根瘤菌，故必須自琉球大豆本身分離出之根瘤菌接種，方有顯著效果。
(2) 在施用石灰及磷肥之情形下，接種琉球大豆根瘤菌有顯著之效果。
(3) 田間試驗各處理間，接種琉球大豆根瘤菌與否，對根瘤數及乾物重所生之差異甚大，接種處理之根瘤數既多，根瘤乾物重亦大。
(4) 施用石灰與磷肥之殘效，以每公頃施用5,000公斤及磷肥施用160公斤（P2O5）為優。
Field experiments of double split Plot design with four replications were carried out at Ping-Cheng to investigate the effect of lime, phpsophate and inoculation on the growth of legume plant, Clycine Koidzum. A pot trial was carried out during the same time at Tari in Taipei for the same purpose but different treatments. In the field expriment, two levels of lime, three levels of phosphate, two kinds of inoculation were involved. While in the pot trail, there were four treatments (1) without lime, phosphate and inoculation (2) without lime and phosphate, with inoculation (3) with lime and phosphate, without inoculation (4) with lime, phosphate and inoculation.
The experimental results may be summarized as follows:
1. Results showed that Rhizobium bacteria isolated from the root nodules of G koidzum was different from the other strains of Rhizobium japonicum. Inoculation of the said Rhizobium bacteria had a significant effect on growth of G. koidzum.
2. Data indicated that liming and phosphate application had a better effect on the fresh weight of G. kidzum plants inoculated with the so-called Rhizobium bacteria.
3. The results of the yield experiments revealed marked difference in the number and dry weight of nodules between inoculation treatment. There were more number and higher dry weight of nodules in the plots with inoculation than that without inoculation.
4. Application of lime with 5 tons/ha. and phosphate 160 kg/ha had a better results on the residual effect in fertility.
