| 【目的】节水节肥、优质高效生产。【方法】以‘安莎19’、‘奥黛丽’甜椒品种为试材，设传统沟灌定期冲肥（CK1）、常规滴灌定期追肥（CK2）、每日定量滴灌1/4剂量（T1）、1/2剂量（T2）、3/4剂量（T3）、1剂量（T4）山崎甜椒专用配方加微量元素通用配方营养液共6个处理，在日光温室条件下研究了不同灌溉施肥方式对土壤栽培甜椒生长、产量及品质的影响。【结果】与CK1和CK2比较，每日定量滴灌营养液的处理促进了甜椒植株生长，增大了根长、根表面积、根体积、根尖数及根干物质量，增强了根系活力和SOD活性，降低了丙二醛量，提高了果实产量并能部分改善其品质，同时水分生产效率和肥料偏生产力显著提高；随着滴灌营养液浓度增加，甜椒生长势、产量、品质和水分生产效率基本呈先升高后降低变化趋势，肥料偏生产力逐渐减小；T2处理的甜椒单株结果数最多，产量最高，T1、T3和T4处理产量无显著性差异；与CK1、CK2相比，T2处理冬春茬分别增产31.11%和22.44%，秋冬茬分别增产35.52%和16.29%，节水率9.45%～30.92%，节肥率59.71%～64.60%；Vc、可溶性糖和游离氨基酸质量分数均以T2处理最高，CK1最小。【结论】每日定量滴灌营养液有利于促进甜椒生长，提高产量，改善品质，并显著提高水肥利用效率，本试验条件下以T2处理效果最好。 |

| Abstract: |
| 【Objective】 Physiological development of crop is controlled by water and nutrient availability, and this paper is to study the impact of different fertigation on yield and fruit quality of sweet pepper grown in solar greenhouse.【Method】 The experiments examined two varieties, ‘Ansha19’ and ‘Aodaili’, and compared six treatments: conventional furrow irrigation with periodic fertilizer topdressing (CK1), conventional drip irrigation with periodic fertilization (CK2), daily fertigation with 1/4 , 1/2 , 3/4 and 4/4 of the strengthened Yamazaki specific nutritious ingredients for sweet pepper formula along with the recipes of trace elements, which were referred as to T1, T2 T3 and T4 respectively. The effects of different fertigation on growth, yield and quality of the sweet pepper cultivated in a solar greenhouse were measured. 【Result】 Compared with CK1 and CK2, daily fertigation with the nutrient solution promoted growth of the sweet pepper, increased the length, surface area, volume, apex number and dry matter of the root, enhanced root vigor and SOD activity, decreased malondialdehyde content, improved fruit yield and quality, water use efficiency and partial productivity of the fertilizer. With nutrient concentration in the drip irrigation increasing, the growth, yield, quality and water production efficiency of the sweet pepper first increased and then decreased, while the partial productivity of the fertilizer decreased monotonically. Fruit number and yield maximized in T2, and there was no significant difference in them between T1, T3 and T4. Compared to CK1 and CK2, T2 increased the yield of spring-pepper by 31.11% and 22.44% respectively, and of autumn-winter pepper by 35.52% and 16.29%, respectively, in addition 9.45%~30.92% increase in water saving and 59.71%~64.60% fertilizer saving. The contents of Vc, soluble sugar and free amino acid were the highest in T2 and lowest in CK1. 【Conclusion】 Daily fertigation promotes the growth and yield of the sweet pepper, in addition to improving its fruit quality, water and fertilizer use efficiency. |
