摘要
应用液体发酵液（５０亿／ｍｌ）研制的根瘤菌液体剂型，其有效活菌数比固体剂型高１．３～２．７倍，在１５～１８℃条件下贮存，６０天后其菌数下降１６％。１９９１～１９９２年，全省２７个试验点试验，液体剂型增产率为１３．４～１６．７％，固体剂型增产率为１３．２～１４．７％，二者增产效果一致，但液体剂型使用量少（５０ｍｌ／亩），简便易行，特别适于大豆机械播种，同时能降低菌剂的生产成本。
The number of living cells of new form Of soybean rhizobium inoculum the was develped through fermentative Original liquid was 1. 3-2. 7 time higher than that Of Peat inoculum. The number of living cells decreased 16% ther 60 days at 15 - 18 condition. The results of 27 locations, trails thoughtout Heilongjiang Province indicated that new form inoculant and peat inoculum could increase grain yield 13. 4-16. 7% and 13. 2-14. 7% respectively. AlthOUgh the increaSe production eflect were the same for two forms inoculum, liquid inoculant could decrease the application rate (soml/mu) and was easy to operate it also is suitable for soybean mechanical sowing and ted nces inoculum production
