摘要:

【目的】促进水温土等资源匮乏的冀西北寒旱区作物生产对水分、养分的合理与均衡利用,保护农田生态环境。【方法】采用交叉式种植方法,在草甸栗钙土和砂质栗土农田,分别设计了包括5个主栽作物的全部组合的轮作与连作田区试验,年际间进行重复,研究区域主栽作物轮作倒茬的产量效果。【结果】在草甸栗钙土农田,与连作相比,不同前茬马铃薯、甜菜、莜麦的产量分别提高了58%—94%、28%—53%和16%—70%;蚕豆与连作相比,除甜菜茬减产外,其他茬口较连作增产4%—43%;马铃薯、蚕豆茬玉米较连作分别增产12%、5%,甜菜、莜麦茬玉米产量仅为连作的81%、93%。在砂质栗钙土农田,不同前茬马铃薯、甜菜的产量分别较连作提高了5%—36%、13%—36%;甜菜茬谷子表现减产,其他茬口的谷子较连作提高了5%—30%;谷子茬莜麦减产,其他茬口莜麦较连作提高了9%—15%;马铃薯、莜麦茬亚麻较连作增产5%、8%,谷子、甜菜茬亚麻产量为连作的94%、99%。【结论】草甸栗钙土田马铃薯→莜麦、马铃薯→甜菜呈现互利轮作,玉米茬马铃薯、莜麦茬甜菜、蚕豆茬甜菜、玉米茬甜菜和蚕豆茬马铃薯表现偏利轮作;砂质栗钙土田莜麦茬马铃薯、马铃薯茬甜菜2种方式表现偏利轮作,可资生产应用。

Abstract:

【Objective】The study was carried out to promote the rational and balanced utilization of water and nutrients in crop production in cold and arid areas of Northwest Hebei province, where water, temperature and soil resources were scarce, and to protect the farmland ecological environment. 【Method】A field experiment of rotation and continuous cropping with five main crop combinations was designed in the meadow chestnut soil and sandy chestnut soil farmland by using the cross planting method. The yield effect of rotation of main crop in the region was studied by repeating the experiment between years. 【Result】Compared with continuous cropping, the yield of potato, beet and oat under rotation conditions in meadow chestnut soil farmland increased by 58%-94%, 28%-53% and 16%-70%, respectively; The yield of faba bean increased by 4%-43% rotated with other crops except for beet; The yield of potato and faba bean stubble forage maize increased by 12% and 5%, respectively, compared with continuous cropping, and the yield of beet and oat stubble forage maize was only 81% and 93% of that of continuous cropping, respectively. In sandy chestnut soil farmland, the yield of potatoes and beets in different Preceding crop fields increased by 5%-36%, 13%-36%, respectively, compared with continuous cropping; The yield of beet stubble forage millet decreased, and it increased by 5%-30% rotating with other crops compared with continuous cropping; The yield of forage millet stubble oats decreased, while that of other stubbles increased by 9%-15% compared with continuous cropping. The yield of potato and oat stubble flax was 5% and 8% higher than that of continuous cropping, respectively, and the yield of forage millet and beet stubble flax was only 94% and 99% of continuous cropping, respectively. 【Conclusion】The rotation of potato and oat, potato and beet in meadow chestnut soil was mutually beneficial, forage maize stubble potato, oat stubble beet, faba bean stubble beet, forage maize stubble beet and faba bean stubble potato showed commensalism rotation. In sandy chestnut soil field, oats stubble potato, potato stubble beet showed commensalism rotation, and this could be applied in production.
