摘要:

研究不同钾肥品种对辣椒生长和产量的影响,为辣椒的合理施肥、高效种植提供理论依据。在盆栽土培试验条件下,以氯化钾和硫酸钾为钾肥肥源,基于不施钾肥(CK)、施氯化钾(K1)和施硫酸钾(K2) 3个不同处理,对辣椒植株株高、茎粗、根茎叶生物量等农艺性状及产量进行了测定,供试辣椒品种为‘正鸿189’和‘艳椒425’。结果表明:与CK组相比,施用氯化钾和硫酸钾能促进辣椒株高、茎粗、根茎叶的生物量,促进了辣椒生长发育,‘正鸿189’K1和K2总生物量较CK分别增加19.26%、25.88%,‘艳椒425’K1和K2总生物量较CK分别增加49.22%、73.93%。2种钾肥均增加了辣椒种子数量、增加了单果重、促进辣椒结实率,从而增加辣椒产量,‘正鸿189’K1与K2处理较CK产量分别增加6.43%、10.46%,‘艳椒425’K1与K2处理较CK产量分别增加(P<0.05) 20.23%、22.49%。2个品种辣椒相比,‘艳椒425’对钾肥更敏感。本试验条件下,辣椒对氯不敏感,在正常施用氮、磷肥条件下,施用硫酸钾在促进辣椒生长、产量的提升方面均优于氯化钾,要实现辣椒高产优质以硫酸钾处理为宜。

Abstract:

The effects of different potassium fertilizer types on the growth and yield of pepper were studied to provide a theoretical basis for rational fertilization and efficient planting of pepper. Under the potted soil culture condition, potassium chloride and potassium sulfate were used as the source of fertilizer. The plant height, stem diameter, biomass of root, stem and leaf, and yield of pepper were measured based on three different treatments: no potassium fertilizer (CK), potassium chloride (K1) and potassium sulfate (K2). The tested pepper varieties were ‘Zhenghong 189’ and ‘Yanjiao 425’. The results showed that: compared with CK group, the application of potassium chloride and potassium sulfate could promote the plant height, stem diameter, and biomass of root, stem and leaf of pepper, and enhance the growth and development of pepper. The total biomass of ‘Zhenghong 189’ under K1 and K2 increased by 19.26% and 25.88%, respectively, compared with that of CK, and the total biomass of ‘Yanjiao 425’ under K1 and K2 increased by 49.22% and 73.93%, respectively, compared with that of CK. The two types of potassium fertilizers increased the number of pepper seeds, the weight of single fruit and the seed setting rate of pepper, thus increasing the yield of pepper. The yield of ‘Zhenghong 189’ under K1 and K2 increased by 6.43% and 10.46%, respectively, compared with that of CK, and the yield of ‘Yanjiao 425’ under K1 and K2 increased by 20.23% and 22.49%, respectively, compared with that of CK (P<0.05). Comparing the two pepper varieties, ‘Yanjiao 425’ was more sensitive to potassium fertilizer. Under the conditions of this experiment, pepper was not sensitive to chlorine, and potassium sulfate was better than potassium chloride in promoting the growth and yield of pepper under the normal application of nitrogen and phosphate fertilizer. In order to achieve high yield and high quality in pepper cultivation, potassium sulfate treatment is an appropriate choice.
