从1990年开始,连续3年进行田间试验。结果表明,麦鱼套作明显减少大麦幼苗盐害;在土壤含盐量为2.0g/kg左右,灌溉水含盐1.2~1.5g/L的情况下,麦鱼套作脱盐速率最快,而蓄淡养鱼土壤脱盐缓慢,0~20cm土层Ca2+富集显著,Na+/Ca2+比下降幅度最大;麦鱼套作明显提高盐土0~20cm土层的有机碳、全氮、碱解氮及有效磷含量,土壤供氮强度及有效磷提高幅度亦以麦鱼套作为最显著。
Beginning in 1990, field trials were conducted for three consecutive years. The results showed that the use of mandarin fish maize significantly reduced the salt stress in barley seedlings. Under the condition of salt content of 2.0 g / kg and salt content of 1.2-1.5 g / L in irrigation water, the desalting rate While the rate of Na + / Ca2 + decreased most significantly in 0-20 cm soil layer. The increase of Na + / Ca2 + ratio in soil layer of 0-20 cm soil layer significantly improved the organic carbon, total nitrogen and alkali of 0-20 cm soil layer Nitrogen and available phosphorus content, soil nitrogen supply and available phosphorus to increase the rate of wheat as the most significant set of fish.
