利用生产食用菌后的棉籽壳料渣作棉花育苗基质研究

Study on Cotton Nursery Substrate Using Cotton Seed Hulls Residue after Producing Edible Mushroom

为了探讨棉花基质育苗的本土化应用技术问题,通过以生产食用菌后的棉籽壳料渣与河沙、草炭不同配比的配方,在田间和室内进行育苗试验。结果表明:按棉籽壳料渣、河沙和草炭的体积比为6:3:1的配方3,其三叶期单株干物质质量和单株叶面积分别比江西高安生产商品基质增加48.4%和73.5%;其育苗成苗率、移栽成活率和实收籽棉产量与对照基质育苗移栽无明显差异;育苗后的基质可还田作肥料,减少了环境污染,实现了棉副产品的综合和循环利用。生产食用菌后的棉籽壳料渣是一种取材方便、节本省工和环保的棉花育苗基质材料,在棉区有较好的推广应用前景。

In order to discuss the localization application of cotton seedling using substrate, the author used cotton seed hulls residue after the production of edible fungi, river sand and peat in different proportion formula to conduct cotton seedling test in field and laboratory. The results showed that： dry mass per plant and leaf area per plant of formula 3 （bulk ratio of seed hulls residue, river sand and peat was 6：3：1） were higher than Jiangxi cotton seedling nursery substrate for 48.4% and 73.5%, respectively; the rate of forming plantlets, survival rate of transplant and the unginned cotton yield had no obvious difference with the other matrix seedling and transplanting; nursery substrate was returned to field as fertilizer to reduce environmental pollution and achieve comprehensive and cyclic utilization. Therefore, being a cotton material, cotton seed hulls residue after the production of edible fungi is easily-obtained, environment-friendly and has a good application prospect. seedling substrate cost-effective and
