Optimization of Preparation Technology of Bio-organic Fertilizer and Its Application in Rice Production
Developing bio-organic fertilizers and applying them to agricultural production are not only increasing soil organic matter and improving soil environment,but also promoting crop growth.In order to explore an economical and practical solid fermentation process for Streptomyces rochei,95％edible mushroom residue and 5％rice straw were mixed for fermentation for 10 days,and 5％Streptomyces rochei broth was inoculated.The entire fermentation cycle was 50 days.After the fermentation was completed,the effective bacterial content in the fermentation material and the germination index met the national standard for biological organic fertilizers.Compared with conventional fertilization,the tiller number,thousand-grain weight and yield of rice were significantly increased after the application of bio-organic fertilizer to the rice production.The tiller number of rice,thousand-grain weight and yield increased by 32.0％,10.6％and 17.6％,respectively after application of bio-fertilizer at a rate of 300 kg/667 m2.Economic benefit analysis showed that there was a better economic benefit at a rate of 200 kg/667 m2 of bio-organic fertilizer.With the increase of the application of bio-organic fertilizers,the yield of rice also increased,but the economic benefits did not increase accordingly.Therefore,in actual production,the appropriate dosage of bio-organic fertilizer is 200 kg/667 m2.
