摘要: 为研究麻地膜对无土栽培辣椒生长发育环境的影响,采用单因素变量法对无地膜土壤栽培(CK)、PE膜土壤栽培(T1)、PE地膜基质栽培(T2)、麻地膜覆盖无土栽培(T3)4种处理下土壤和基质基本理化性状、辣椒生长发育状况以及品质、 辣椒根际土壤微生物数量的差异进行了研究。结果表明,对比CK、T1、T2处理,T3处理明显提高了辣椒的产量和品质,辣椒可溶性糖和VC含量较CK分别提高21.13%、49.26%。与定植前比较,CK、T1、T2、T3处理的土壤或基质中的有机质含量、速效氮含量、速效磷含量和速效钾含量均增加,其中T3处理含量增加最明显。通过分析可知,麻地膜对基质的理化性质提升较为明显,改善了基质电导率以及孔隙度大小,提高了地温,增加了基质中细菌的多样性,降低了真菌丰度,进而有利于加速养分分解,对植物根部环境和生长发育有较大的作用。

Abstract: In order to study the effect of hemp mulch on the growth and development environment of soilless cultivated peppers, the basic physicochemical properties of soil and substrate, growth and development of peppers, as well as the quantity of soil microorganisms of peppers' inter-root were investigated by using the single facter variable method in four treatments, namely, soil culture without mulching (CK), PE film soil culture (T1), PE film substrate cultivation (T2), and hemp film-covered soilless culture (T3). The results showed that compared with the CK, T1 and T2 treatments, the T3 treatment significantly improved the yield and quality of peppers. Compared with the CK, the soluble sugar and VC content of peppers increased by 21.13% and 49.26%, respectively. Compared with the pre-planting period, the organic matter content, quick-acting nitrogen content, quick-acting phosphorus content and quick-acting potassium content in the soil or substrate of CK, T1, T2 and T3 treatments were increased, among which the content of the T3 treatment increased the most obviously. It could be seen from the analysis that hemp mulch enhanced the physicochemical properties of the substrate more obviously, improved the substrate conductivity as well as the porosity size, raised the ground temperature, increased the diversity of bacteria in the substrate, reduced the fungal abundance, which in turn was conducive to accelerating the decomposition of nutrients, and had a greater effect on the root environment and the growth and development of plants.
