气化渣和花生壳添加对小白菜生长的影响

为明确气化渣与花生壳添加对作物生长的影响，实现气化渣与花生壳的资源化利用，本研究以气化粗渣和腐熟的花生壳为添加材料进行小白菜风沙土盆栽试验，研究了气化渣、花生壳和风沙土不同配比条件下小白菜的生长特征(出苗率、建值率、生物量)。结果表明：(1)与未添加气化渣处理相比，气化渣添加量占比为5%处理下，小白菜建植率显著提高，且生物量最大。(2)花生壳添加对小白菜出苗率和建植率无显著影响，但5%的花生壳添加量可有效提高小白菜的生物量。(3)隶属函数法分析表明，当气化渣与花生壳的添加总量与沙土量的比值为5%,气化渣占气化渣和花生壳添加总量的33%时，小白菜的综合生长状况最佳。该研究结果可为气化渣的资源化利用提供一定参考。

Effects of Gasification Slag and Peanut Shell Addition on Growth of Brassica rapa chinensis

To investigate the effects of gasification slag and peanut shell addition on the growth of crop and to promote their resource utilization,a pot experiment of Brassica rapa chinensis in aeolian sandy soil was conducted, using decomposed peanut shell combine with gasification coarse slag as the additive substrates. The growth characteristics of Brassica rapa chinensis was investigated under different ratios of gasification slag, peanut shell and aeolian sandy soil. The results showed that the addition of gasification slag at 5% significantly increased the planting rate and biomass of Brassica rapa chinensis compared to the treatment without gasification slag. The addition of peanut shell had no significant effect on the seedling emergence and planting rate, but 5% addition of peanut shell effectively increased the biomass of Brassica rapa chinensis. The synthetic appraising index of Brassica rapa chinensis was the highest when the proportion of (gasification slag+ peanut shell)/aeolian sandy soil was recorded as 5%, and gasification slag/(gasification slag+ peanut shell) was 33%. The analysis of membership function suggested that this ratio was optimal for Brassica rapa chinensis growth. The results provide useful reference for the resource utilization of gasification slag and peanut shell in the agricultural industry.
