摘要/Abstract

摘要： 保水剂可改良土壤结构、提高植物水肥利用效率，并对植物的产量和品质产生影响。为研究保水剂对袋式复合沙培辣椒的影响，以辣椒栽培品种‘瑞霸五号’为材料，于幼苗定植前在栽培基质中按基质体积分别穴施0、0.075、0.150、0.225、0.300和0.375 g·L^-1的淀粉型保水剂，对比分析不同剂量保水剂对辣椒生长发育、生理生化及果实产量与品质的影响。结果表明，在栽培基质中适量施加保水剂（≤0.300 g·L^-1）有利于促进辣椒植株的生长；提高叶片的光合效率；叶片SOD、POD和CAT活性增强，叶片游离脯氨酸、可溶性糖和可溶性蛋白含量增加，降低逆境对植株造成的伤害；提高辣椒果实产量；果实中维生素C、可溶性糖和可溶性蛋白含量升高，硝酸盐含量也显著增加。随着保水剂剂量的进一步增加（≥0.375 g·L^-1），辣椒植株的真叶数、叶面积等又有所降低；叶片SOD、POD和CAT的活性减弱，叶片可溶性糖和可溶性蛋白含量减少；果实硬度降低、果肉厚度减少；单株结果数减少从而造成单株产量降低；果实中维生素C、可溶性糖和可溶性蛋白含量降低，硝酸盐含量进一步增加，从而造成品质下降。由此可见，在辣椒定植栽培基质中施加适宜剂量（0.300 g·L^-1）保水剂有助于促进辣椒的生长发育。

Abstract: The water-retaining agent can change the soil structure, enhance the utilization efficiency of water and fertilizer and improve the yield and quality of crop. In order to study the effect of water-retaining agent on the growth and quality of bag-shaped compound sape peppers, the pepper cultivar ‘Ruiba 5’ was used as material. Six treatments (0, 0.075, 0.150, 0.225, 0.300, and 0.375 g·L^-1) of water-retaining agent were studied. The growth, physiology, yield and quality of pepper under different treatments were analyzed. The results showed that the application of an appropriate amount of water-retaining agent in the cultivation substrate was conducive to reduce the damage caused by stress and increase the yield of pepper by improving plant growth and leaf photosynthetic efficiency, enhancing the activities of SOD, POD and CAT, increasing the contents of free proline, soluble sugar and protein. With the increase of water-retaining agent, the numbers and areas of leaves were decreased, the activities of SOD, POD, CAT and the contents of soluble sugar and protein were reduced, the firmness and thickness of fruit were also affected, and the yield was decreased due to the reducing of fruit number. In conclusion, the application of 0.300 g·L^-1 water-retaining agent in the cultivation substrate before pepper planting would promote the growth and development of pepper.
