百泰生技肥料（Bs Y1336+复合有机肥）水稻田间对比试验结果分析

为了进一步研究台湾百泰生物科技公司（简称百泰生技公司）研制生产的生物菌复合有机肥对水稻的增产作用,通过生物菌（BsY1336）、复合有机肥与普通化肥水稻田间多重对比试验,对水稻长势、生育期、病虫害发生、产量构成因素及产量变化的影响进行比较分析。结果表明：水稻田间施用台湾百泰提供的生物菌＋复合有机肥与普通化肥相比,在总氮、磷、钾含量与对照相近的情况下,生育期稍微长1～2天,后期叶片较翠绿,有效光合作用时间延长,对灌浆提高粒重有明显的促进作用;对纹枯病的发生具有较好的抑制作用;在防治纹枯病下,比施用普通化肥每公顷可增产稻谷533.7kg,增幅6.67%,在没有防治纹枯病下,可增产稻谷392.4～768.8kg,增幅5.04%～10.37%,对产量的增产作用达到显著和极显著水平,有较好的增产效果,具有良好的经济效益。

Result Analysis for the Contrast Tests of Biotech Fertilizer (Bs Y1336+Compound Organic Fertilizer) in the Rice Field

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.
