【摘要】：【目的】研究新疆伊犁地区伊贝母的最佳施肥技术模式。【方法】通过采用四因素三水平正交试验设计,设计微生物菌肥、磷肥,生物有机肥+有机物料腐熟剂,精制有机肥+有机物料腐熟剂4因素,在优化施肥(2水平)基础上,设计1水平(2水平×0.5)、3水平(2水平×1.5),正交处理共9个,对伊贝母生长及土壤进行了测定。【结果】不同施肥量处理下的伊贝母植株高度、伊贝母植株鲜重、鳞茎鲜重、土壤有机质、土壤全氮含量和土壤p H值均不同;随着伊贝母生育进程的推进,各个处理下的土壤p H均表现为萌芽期显著高于现蕾期和始花期,而土壤有机质和土壤全氮含量规律并不明显;不同施肥量处理下,伊贝母每667 m~2株数没有明显差异;在同一微生物菌肥施用量下,伊贝母产量的变化趋势无明显规律,处理8即微生物菌肥为6 kg/667m~2,磷肥为18 kg/667 m~2,生物有机肥+有机物料腐剂为16 kg/667 m~2,精制有机肥+有机物料腐剂为60 kg/667 m~2时,伊贝母产量最高为381.14 kg/667 m~2;在单一微生物菌肥施用量下,伊贝母产量的变化趋势无明显规律。【结论】以微生物菌肥、磷肥基施为主,配施生物有机肥、有机物料腐熟剂,生育期开沟追施微生物菌肥,可获得伊贝母高产。
[Abstract]:[objective] to study the best fertilization technology model of Fritillaria japonicus in Yili area, Xinjiang. [methods] by using four factors and three levels orthogonal design, the microbial fertilizer, phosphorus fertilizer and organic fertilizer organic fertilizer were designed. On the basis of 4 factors of cooked agent of refined organic fertilizer, on the basis of optimizing fertilization level 2, the design of level 1 and 2 脳 0. 5 / 2 level 脳 1. 5 ~ 2 level 脳 1. 5%, and 9 orthogonal treatments were carried out. [results] the plant height, plant fresh weight, bulb fresh weight, soil organic matter, soil total nitrogen content and soil pH value of different fertilization treatments were different. With the development of Fritillaria japonica, the soil pH in different treatments was significantly higher than that in budding stage and flowering stage, but the rules of soil organic matter and soil total nitrogen content were not obvious. There was no significant difference in the number of plants per 667m ~ (2) of Fritillaria japonica, and there was no obvious change trend of the yield of Fritillaria japonica under the same application rate of microbial fertilizer. In treatment 8, the yield of Fritillaria japonicus was up to 381.14 kg/667 m-2 when microbial fertilizer was 6 kg / 667mc-2, phosphorus fertilizer was 18 kg/667 mm2, organic material rot agent of biological organic fertilizer was 16 kg/667 mt2, and organic material rot agent of refined organic fertilizer was 60 kg/667 m2, the highest yield of Fritillaria was 381.14 kg/667 m-2. [conclusion] High yield of Fritillaria Fritillariae could be obtained by applying microbial fertilizer, phosphate fertilizer, organic fertilizer, organic material maturing agent, and topdressing microorganism fertilizer at growth stage.
