增施腐殖化木耳菌渣对玉米养分和产量的影响

Effect of Adding Humic Fungus Residue on Nutrient and Yield of Maize

通过研究增施有机物料对石灰性黑钙土上玉米产量和养分吸收的影响规律,以期为腐殖化木耳菌渣在石灰性黑钙土改良中科学应用提供理论依据。以先玉335为供试材料,设置不施肥处理、常规施肥对照、腐殖化木耳菌渣+常规施肥3个处理,小区试验设计,3次重复。结果表明:增施腐殖化木耳菌渣与常规施肥对照相比显著提高了玉米干物质积累量、氮和磷吸收量,但不会对玉米钾吸收产生显著影响;增施腐殖化木耳菌渣提高了玉米穗长、穗粒数和穗重,产量和产值分别提高了20.52%和4747.5元·hm^(-2),同时提高了玉米氮、磷、钾肥利用效率。综合分析认为,在当地常规施肥基础上增施腐殖化木耳菌渣有利于促进玉米生长、提高产量和肥料利用效率。

In order to provide a theoretical basis for the scientific application of humic fungus residue in the improvement of calcareous black calcareous soil,effects of increasing organic materials on maize yield and nutrient absorption were studied.Xianyu 335 was used as experimental material,three treatments were set up:no fertilization treatment,conventional fertilization control,humic fungus residue and conventional fertilization.The results showed that the dry matter accumulation,N and P uptake of maize were significantly increased by adding humic fungus residue,but no significant effect on K uptake was observed.The ear length,grain number and weight of maize were increased by 20.52%and 4747.5 yuan·hm-2 respectively,and the N,P and K utilization efficiency of maize were increased by applying humic fungus residue.It was concluded that the application of humic fungus residue on the basis of local conventional fertilization could promote maize growth,increase yield and fertilizer utilization efficiency.
