不同栽培措施对盐碱地辣椒根区盐碱动态及辣椒生长的影响
Effects of Different Cultivation Measures on Salt-alkali Dynamics in the Root Zone and Growth of Pepper in Saline-alkali Soil
摘要
Abstract
Taking'Bola Tianjiao 60'as the experimental material,mulched drip irrigation(-30 kPa)and non-mulched drip irrigation(-30 kPa)were used as controls.Five treatments were established,included mulched drip irrigation combined with leaching for salt suppression,microbial inoculants,soil amendments,and different soil matric potentials(-25 kPa and-35 kPa).The effects of these treatments on total soil salinity(TS),pH,and pepper growth in the 0-40 cm soil layer of the root zone were investigated,in order to provide references for efficient and high-yield pepper cultivation in saline-alkali land in the Hetao Irrigation District.The results showed that,1)compared with non-mulched drip irrigation,mulched drip irrigation significantly inhibited salt accumulation in the 0-20 cm soil layer;2)mulched drip irrigation combined with soil amendments,microbial inoculants,or a higher soil matric potential(-25 kPa)effectively reduced TS and pH in the rhizosphere,among which the soil amendment showed the most significant salt-reducing effect at the full-bloom stage,while the microbial inoculant had a more persistent effect,and the effects of all measures were mainly concentrated in the 0-20 cm soil layer;3)leaching for salt suppression was only effective in the short term,while soil salinity re-accumulated and pH increased in the later stage;4)the comprehensive evaluation results showed that,compared with single mulched drip irrigation,mulched drip irrigation combined with soil amendments had the best effect,increasing pepper yield by 12.07％.关键词
