摘　　要：为明确大棚内麻地膜覆盖对辣椒营养生长的影响,测量不同覆盖处理下辣椒主要营养生长时期的株高和分枝级数,开花初期的开花率,结果初期的结果率,结果期辣椒的总产量,拔棵期辣椒的营养器官干物质积累及养分积累。结果表明,白色麻地膜覆盖下辣椒的株高一直最高,除5月2日取样外,其余时期分枝级数也最多;白色麻地膜覆盖下辣椒营养器官干物质积累和养分积累最高;白色麻地膜覆盖辣椒开花率比无覆盖高53.34%,结果率同样为白色麻地膜覆盖最高;白色麻地膜覆盖产量比无覆盖高31.20%。研究表明,麻地膜覆盖促进辣椒营养生长,同时没有对生殖生长造成不利影响,可以增加辣椒产量。To identify the effects of bast fiber mulching film on vegetative growth of pepper in greenhouse,the plant height and number of branches were measured in the main period of vegetative growth,the flowering rate of pepper was measured in the early flowering period,the fruit set percentage of pepper was measured in the early fruiting period,the total yield was measured in the fruiting period,the dry matter accumulations and the nutrient accumulations of vegetative organs were measured in late growth stage of four treatments with different mulching film.The results showed that the height of pepper with white bast fiber mulching film was the highest among these treatments,the number of branches was the maximum excluding the sample obtained on May 2nd;the dry matter accumulations and the nutrient accumulations of vegetative organs with white bast fiber mulching film were the maximum among these treatments;the flowering rate with white bast fiber mulching film was 53.34% higher than that with no coverage,and the fruit set percentage with white bast fiber mulching film was the maximum among these treatments;the total yield with white bast fiber mulching film was 31.20% higher than that with no coverage.Conclusion was drawn that bast fiber mulching film could promote the vegetative growth of pepper,had no adverse effects on reproductive growth of pepper,and could increase the total yield of pepper.
