不同滴灌带配置对辣椒耗水量及产量的影响
Effects of Different Configurations of Drip Irrigation Belt on Water Consumption and Yield of Capsicum annuum L.
摘要
Abstract
To explore the optimal water-saving method for field pepper,'Honglong No.22'was used as the test material and three configurations of drip irrigation belt were set,namely,labyrinth-type high flow(L30 with 3.0 L/h drip rate and 30 cm spacing between drippers),inlaid-type medium flow(L25 with 2.0 L/h drip rate and 25 cm spacing between drippers)and inlaid-type low flow(L25 with 1.38 L/h drip rate and 25 cm spacing between drippers)to investigate the effects on irrigation uniformity,survival rate,water consumption,growth indicators and economic benefits of peppers.The results showed that the low-flow drip irrigation configuration achieved the highest irrigation uniformity coefficient(0.946)and survival rate(98.80%),significantly outperforming the high-flow(CK)treatment.Compared with CK,the low-flow treatment saved 18 m3 water per 667 m2(4.16%reduction),increased yield by 3.86%per 667 m2 and raised net profit by 20.43%per 667 m2.In addition,low-flow drip irrigation could significantly increase the plant height and shoulder width of pepper,but the fruit length,the number of single hole fruit setting and the number of bifurcation were not significantly different from other treatments.In conclusion,the inlaid-type low-flow drip irrigation belt is recommended for pepper cultivation with mulch covering in the Hexi Corridor region,achieving both water-saving and economic benefits.关键词
