摘要:

为了探究聚琥珀酰亚胺(PSI)施用量对华北地区夏玉米-冬小麦轮作系统作物产量的影响,本研究以夏玉米(郑单958)和冬小麦(济麦38)为试验材料,设置不同PSI施用量处理,开展了连续2年共4季的田间试验,系统分析了PSI对两种作物产量的影响。结果表明:在首个生长季施用PSI可显著(p<0.05)提高前3个生长季作物的产量。PSI主要通过增加夏玉米的穗粒数和冬小麦的有效穗数实现增产效应。在常规施肥基础上,PSI施用量为6.0~12.0 kg·hm-2时,其有效期为22~23个月;当施用量提高至18.0 kg·hm-2时,有效期可延长至24个月。综合考虑施肥效果的稳定性和土壤微生物活性等因素的影响,建议在每年夏玉米播种期以种肥同播方式施用PSI 6.0~12.0 kg·hm-2

Abstract:

To investigate the effects of polysuccinimide (PSI) application rate on crop yield in the summer maize-winter wheat rotation system in north China,a field experiment was conducted over two consecutive years (four growing seasons) using summer maize (Zhengdan 958) and winter wheat (Jimai 38) as test materials. Different PSI application rates were set as treatments to systematically analyze their impacts on the yields of both crops. The results showed that PSI application in the first growing season significantly(p<0.05) increased the yields of both crops during the initial three consecutive seasons. PSI enhanced maize yield primarily by increasing kernel number per ear,and improved wheat yield by increasing the number of effective panicles. Under conventional fertilization,the effective duration of PSI was 22-23 months at application rates of 6.0-12.0 kg·hm-2,and extended to 24 months when the rate was increased to 18 kg·hm-2. Considering the stability of the fertilization effect,soil microbial activity,and other factors,it is recommended to apply PSI at 6.0-12.0 kg·hm-2 simultaneously with seeds during the summer maize sowing period each year.
