Abstract

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.
