摘要
通过不同模式玉米秸秆覆盖种植马铃薯,探讨不同覆盖模式种植对土壤水热和马铃薯生长的影响,筛选出定西旱作农业区玉米秸秆覆盖马铃薯种植的最佳模式。结果表明,秸秆覆盖在马铃薯生长过程中对土壤表层的温度和水分调控明显,能够降低土壤温度、增加土壤水分,有利于马铃薯的生长;与传统露地种植相比较,秸秆覆盖栽培平均增产15.6%,马铃薯商品属性提高。
Through different types of corn stalks covered with potato planting,the effects of different mulching patterns on the soil water and heat and potato growth were discussed,and the best mode of corn stalk-covered in potato cultivation in Dingxi dry farming area was screened out.The results showed that the stalk cover increased the temperature and moisture of the soil surface during the growth of potato,which could reduce the soil temperature and increase the soil moisture.Compared with the traditional open field planting,the yield of potato by stalk covering increased by 15.6%,the commodity attributes have also improved.
