摘要

摘要: 目的通过叶面喷施不同钙源研究其对辣椒的农艺性状、果实钙含量的影响，为生产上辣椒果实钙含量的提升、产量增加和品质改善提供参考。方法以辣椒为试验材料，采用基质培养，设置CK（叶面喷施清水）、G1（叶面喷施氯化钙）、G2（叶面喷施糖醇钙）、G3（叶面喷施小分子肽钙）4个处理，测定辣椒的主要农艺性状、钙含量、产量和品质等指标。结果喷施3种不同的钙源均可加快辣椒果实的成熟，提高地上部钙素在果实的分配率。G3与CK相比，辣椒的地上部鲜重显著增加22.02%，单株产量为536.9 g，显著增产38.77%。果实钙含量与积累量分别达2.78 g·kg⁻¹和96.86 g·株⁻¹，较CK处理显著升高46.32%和78.25%。辣椒地上部中，果实的钙素分配率较CK处理显著提高58.58%，维生素C含量达0.6378 mg·g⁻¹，较CK处理显著增加17.29%；G3与G1相比，辣椒的单株产量、单果重和维生素C含量分别显著提高18.0%、33.8%、18.3%；G3与G2相比，辣椒的地上部鲜重、成熟果个数和单株产量均显著提高。地上部氮、钾、钙的积累量增加。结论与氯化钙和糖醇钙相比，小分子肽钙能更好地从辣椒的叶片转移到果实中，进而提高果实钙含量。供试条件下，在促进辣椒生长、提高产量和品质方面，叶面喷施小分子肽钙的处理效果最佳。

Abstract: Objective Effects of foliar spraying different calcium solutions on the agronomic traits of chili pepper were studied for crop yield and quality improvements. Method Four foliar spraying treatments using water (CK) or solutions of calcium chloride (G1), calcium sugar alcohol (G2), and small molecular peptide calcium (G3) were performed on chili pepper plants. Major agronomic characteristics, calcium content, yield, and quality of the plants were determined. Result The various calcium sprays hastened the pepper ripening and increased the fruit calcium content. Compared with CK, the G3-treated peppers increased significantly by 22.02% on fresh weight and by 38.77% at 536.9 g on yield per plant. Meanwhile, the content and the accumulation of calcium in the fruit reached 2.78 g·kg⁻¹ and 96.86 g per plant, representing significant increases over CK by 46.32% and 78.25%, respectively. In the aboveground pepper plant, the fruits had a significantly increased share of calcium by 58.58% and Vitamin C (0.6378 mg·g⁻¹) by 17.29% over those of CK. The G3-treated peppers also had higher yield per plant, fruit weight, and Vitamin C by 18.0%, 33.8%, and 18.3%, respectively, than the G1-treated ones, and significantly higher fresh shoot weight, mature fruit count, and yield per plant than the G2 counterparts. The sprays also resulted in more accumulations of nitrogen, potassium, and calcium in the aboveground parts of the plants. Conclusion The small molecule peptide calcium used in the foliar spraying was more efficient than the other forms in transferring calcium from the leaves to the fruits of a chili pepper plant. It was recommended for promoting the plant growth as well as increasing the yield and nutritional quality of chili peppers.
