Abstract:

To further application the yield increasing effect of the biological bacterium compound organic fertilizer which produced by Taiwan Biotech Company, we did some multiple repeat contrast tests with biological bacterium (Bs Y1336), compound organic fertilizer and common fertilizer, and analyzed the influence to the growth vigor, growth period, diseases and insect pests occurrence, yield components and the yield change in the rice field. The results showed that, when the total content of nitrogen, phosphorus, potassium was close to control, used the biological bacterium supplied by Biotech Company and compound organic fertilizer, the growth period would be longer of 1-2 days, the leaves would be more green in later stage, the effective of photosynthesis would last longer, promoted to enhance the grain weight in filling obviously, and had better inhibition action to sheath blight. Compared with using common fertilizer in per hm2 rice field, the yield increased by 533.7 kg, increase amplitude was 6.67% with controlling sheath blight, and the yield is also increased by 392.4-768.8 kg without sheath blight control, increase amplitude was 5.04%-10.37%, reach to the significant level and extremely significant level, have a better yield-increasing effect and good economic benefit.
