摘要
研究麦套春棉不同带宽的麦、棉产量及其土壤养分动态变化。结果表明,皮棉产量在1125kg/hm2以上,以180cm的带宽为好;皮棉产量在1125kg/hm2以下,以160～170cm的带宽为宜。在中上等土壤肥力条件下,每年施纯N、P2O5、K2O分别为375、210、150kg/hm2时,可产皮棉1125kg/hm2、小麦4500kg/hm2,并能使土壤肥力不断提高。该研究结果为黄淮海地区推广麦套春棉发展高产高效农业提供了参考。
The dynamic changes of yield of wheat and cotton and soil nutrients with different width in intercrop wheat and spring-cotton farmland were researched.The results showed that if expecting the yield of lint cotton is over 1 125 kg/hm2,the width should be 180 cm;if expecting the yield of lint cotton is less than 1125 kg/hm2,the width should be 160～170 cm.Under the condition of middle-upper soil fertility,fertilizing N of 375 kg/hm2,P2O5 of 210 kg/hm2 and K2O of 150 kg/hm2 respectively,the yield of lint cotton will reach 1 125 kg/hm2,the yield of wheat will reach 4500 kg/hm2,and it could also improve the soil nutrient at the same time.The results can provide reference for the development of high-efficiency agriculture in Huanghe-huaihai region.
