商品有机肥肥效试验报告

Experimental report on fertilization effect of commercial organic fertilize

【目的】探索有机肥对水稻产量产值的影响及对土壤改良效果,为耕地保护与质量提升项目的进一步实施提升技术支撑,为大面积推广商品有机肥提供科学依据。【方法】设3个处理,每个处理重复3次,共9个小区,随机区组排列。通过在常规配方基础上,增施广西鸿生源有机肥和宜州市三堡有机肥两种商品有机肥的试验,测定早稻产量及土壤理化性质的变化。【结果】施用有机肥对各小区水稻的生育期差别不大,增施有机肥的两个处理亩有效穗、穗粒数、实粒数、千粒重都较对照增加。增施有机肥的两个处理比试验前及对照土壤容重稍有下降,土壤有机质、全氮、有效磷、有效钾的含量较对照有所增加。【结论】增施商品有机肥能促进生长和结实,改善水稻的生物学性状,对水稻产量有明显的增产作用,同时能改良土壤结构和环境,培肥土壤肥力,值得大力推广。

【Objective】To explore the impact of organic fertilizer on rice production quantity and value; to provide technical support for farming land conservation and quality improvement and for further execution of the project; to provide scientific basis for vast extension of commercial organic fertilizer.【Method 】Conducted field contrast test,applying the arrangement of randomized block with three repetition,total are 9 sub-areas. Based on regular formula,fertilization of two kinds of commercial fertilizer,Guangxi Hong Sheng Yuan organic fertilizer and Yi Zhou San Bao organic fertilizer are used for experiment,so as to measure the early season rice yield and the change of earth physical and chemical properties.【Result】Fertilization of organic fertilizer does not make big difference to the rice growing period of different subarea.t The efficient spikes of rice,number of spikes,number of solid spikes and the thousand seed weight from the two experimental plots increase in comparison. The earth bulk density of the two experimented plots is slightly decreased by comparison to the state before experiment. The content of earth organic material,total nitrogen,effective phosphorus,effective potassium is increased in comparison.【Conclusion】Fertilization of commercial organic fertilizer can promote rice growth and spiking,can improve rice biocharacter and obviously increase the rice yield,and meanwhile it can improve the earth structure and environment,increase the soil fertility,therefore it is worth of vast extending.
