以春玉米为研究对象,通过磁化水灌溉试验,研究磁化水灌溉条件下不同灌水量(4 200,4 800,5 400 m3/hm2)对土壤水盐分布、玉米干物质量积累、产量及生长特性的影响,以探寻3 500 Gs磁化强度磁化水灌溉条件下适宜的灌水量,为促进塔里木盆地农业资源高效利用提供相关数据支持。结果表明:不同灌水量下磁化水灌溉均能提高土壤含水量,40—60 cm土层土壤盐分淋洗效果优于0—20 cm土层;磁化水灌溉可促进玉米植株生长及产量增加,各处理磁化水灌溉玉米产量较非磁化处理增加了2.11%~19.31%;磁化水3 500 Gs磁化强度灌溉4 800 m3/hm2处理产量均最佳,水分利用效率及灌溉水利用效率均达到最大,分别为2.64,2.86 kg/m3。因此,与非磁化灌溉相比,适宜的磁化水灌溉量可改善玉米穗部干物质积累,有利于提高玉米的产量及水分利用效率。
Taked spring corn as the research object
through magnetized water irrigation experiments
the effects of different irrigation amounts (4 200
4 800
5 400 m3/hm2) on the distribution characteristics of soil water and salt
dry matter accumulation
yield and growth of maize under the conditions of magnetized water irrigation were studied. The impact of characteristics
to explore the appropriate irrigation volume under the conditions of 3 500 Gs magnetized water
to provide relevant data support for promoting the efficient use of agricultural resources in the Tarim Basin. The results show that magnetized water irrigation could increase soil water content under different irrigation amounts. The soil salt leached effect of 40-60 cm soil layer was better than that of 0-20 cm soil layer. Magnetized water irrigation could promoted corn plant growth and increased yield. Each treatment of magnetized water Irrigated corn yield increased by 2.11%~19.31% compared with non-magnetized treatment; magnetized water 3 500Gs magnetization intensity irrigation 4 800 m3/hm2 treatment yields the best
water use efficiency and irrigation water use efficiency reached the maximum
respectively 2.64 and 2.86 kg/m3.Therefore
compared with non-magnetized irrigation
the appropriate amount of magnetized water irrigation could improved the dry matter accumulation of corn ears
which was beneficial to increased the yield and water used efficiency of corn.
