绣球菌渣复合基质对黄瓜幼苗素质及产量的影响

为减少绣球菌渣废弃物带来的潜在农业面源污染的风险,探讨其资源化利用的可行性,本试验将绣球菌渣与草炭、珍珠岩进行复配,研究不同绣球菌渣复合基质理化性质的差异,黄瓜幼苗生长、生理生化特性及成苗栽培后产量差异,探讨不同基质配方对黄瓜幼苗素质的影响。结果表明,绣球菌渣复合基质的理化性质均在适合黄瓜生长的范围内;配方(绣球菌渣∶草炭∶珍珠岩=1∶1∶1)与对照(CK,草炭∶珍珠岩=2∶1)相比,出苗后20 d,幼苗根冠比、可溶性糖、叶绿素含量分别提高9.84%、25.89%、56.67%,且根系活力是CK的1.79倍;单株果数和产量分别提高17.82%和10.80%,绣球菌渣最佳使用比例为33%。本研究结果为绣球菌渣资源化利用提供了理论依据。

Effects of Sparassis Crispa Residue Composite Substrate on Quality and Yield of Cucumber Seedlings

In order to reduce the risk of potential agricultural non-point source pollution caused by Sparassis crispa residue waste, and to explore the feasibility of its resource utilization. In this experiment, Sparassis crispa residue was mixed with peat and perlite to study the difference of physical and chemical properties of different composite matrix, the growth of cucumber seedlings, physiological and biochemical characteristics and the difference of yield after seedling cultivation, and to explore the effect of different matrix formulations on the quality of cucumber seedlings.The results showed that the physicochemical properties of the compound matrix of Sparassis crispa residue were in the range suitable for cucumber growth; compared with the control (CK, peat: perlite=2:1), the root-shoot ratio, soluble sugar and chlorophyII of the formulation (Sparassis crispa residue∶peat∶perlite=1∶1∶1) increased by 9.84%, 25.89% and 56.67% respectively; and the root vigor was 1.79 times of CK; and the fruit number and yield of per plant cucumber increased by 17.82% and 10.80% respectively. The optimum use ratio of Sparassis crispa residue is 33%. The results of this study provide a theoretical basis for the resource utilization of Sparassis crispa residue.
