加工型辣椒干物质积累与分配对种植方式的响应

Response of Dry Matter Accumulation and Distribution of Processed Pepper to Planting Patterns

以加工型辣椒品种‘英潮红4号’为试材,采用裂区设计方法,研究了加工型辣椒干物质积累与分配对种植方式的响应,以期为加工型辣椒高产高效栽培技术提供参考依据。结果表明:不同种植方式(3种密度、3种行距处理)下加工型辣椒茎和叶的干物质积累量均表现先增后减的变化趋势,其峰值在盛果期,而果实干物质的积累量随生育时期的推进逐渐增加。与行距60+60处理相比,大小行种植(80+40、70+50)有利于促进各器官干物质的积累与分配,提高茎、叶对果实的贡献率,并且密度较高时其对果实的贡献更加明显,其中密度82 500株·hm^(-2)、行距80+40处理时,植株群体分布合理,各器官干物质积累最多,茎和叶的干物质转运量、转运率以及对果实的贡献率均为最高,增产潜力最大,为加工型辣椒最佳种植方式。

Taking processed pepper ‘Yingchaohong No.4’ as materials, the responses of dry matter accumulation and distribution of processed pepper to planting methods were studied by using split zone design method, in order to provide reference for high-yield and high-efficiency cultivation technology of processed pepper.The results showed that the dry matter accumulation of the stems and leaves of processed pepper under different planting patterns(three kinds of densities and three kinds of row spacing treatments) displayed a trend of increasing first and then decreasing, and the peak value was in the fruiting stage, while the dry matter accumulation of fruits was gradually increasing with the advancement of the growth period.Compared with the row spacing 60+60 treatment, the wide-narrow planting(80+40,70+50) was conducive to promoting the accumulation and distribution of dry matter in various organs, increasing the contribution rate of stems and leaves to fruits.And when the density was higher, its contribution to the fruit was more obvious.When the density was 82 500 plants per hectare, and the row spacing was 80+40,the plant population was distributed reasonably, the dry matter accumulation of each organ was the most, the dry matter transshipment, transfer rate and the contribution to the fruit of stem and leaves was the highest, and the potential for increasing yield was the best.It was the best planting patterns of processed pepper.
