通过田间小区磁化水滴灌试验,研究了磁化水膜下滴灌对土壤水盐分布特征、棉花生长特性及产量的影响。结果表明:磁化水灌溉可以提高土壤含水量,促进棉花根系对水分的吸收,0-100 cm土层内磁化强度为3 000 Gs时的土壤含水量最大,保水效果最好。磁化水灌溉可以有效降低土壤盐分含量,加快土壤盐分的淋洗,0-100 cm土层内各磁化水处理土壤平均含盐量表现为3 000 Gs < 4 000 Gs < 1 000 Gs < 5 000 Gs < 0 Gs,磁化淡水处理的土壤脱盐率为2.7%~28.2%,3 000 Gs磁化处理的土壤脱盐率最高;磁化微咸水处理的土壤积盐率为21.7%~33.9%。磁化水滴灌可以促进棉花生物量及产量的增长,淡水、微咸水磁化处理的产量较未磁化处理增加了8.98%~31.4%,3 000 Gs磁化处理下的棉花产量最高。从棉花生长特征、产量、水分利用效率等方面综合考虑,3 000 Gs为最佳磁化强度处理。
A field experiment was conducted to study the soil water-salt distribution and cotton growth using magnetized water for mulched drip irrigation. Results showed that magnetized water used in the experiment could improve the soil water retention and holding capacity effectively
and promote the water absorption of cotton roots. The soil moisture content of 3 000 Gs magnetized water irrigation treatment was highest at the soil layer of 0-100 cm. The magnetized water irrigation could reduce the soil salt content effectively
due to the magnetized water treatment could facilitate the soil salt leaching from the main root area of cotton into the below. At the 0-100 cm soil layer
the salt contents under magnetized water irrigation treatments were 3 000 Gs(low) < 4 000 Gs < 1 000 Gs < 5 000 Gs < 0 Gs. The soil desalination rates under mulched drip irrigation with magnetized fresh water were 2.7%~28.2%
among which the 3000Gs treatment had the most significate impact on reducing soil salinity. The soil desalination rates for magnetized brackish water treatments were 21.7%~33.9%. The magnetized water irrigation could improve the cotton biomass and output. The yields of seed cotton of magnetized water were increased by 8.98%~31.40% compared with ordinary water. The 3 000 Gs treatment was the best magnetic treatment by taking into consideration of both cotton output and water use efficiency.
