玉米秸秆还田对小麦生长和土壤水分含量的影响
Response of Wheat Growth and Soil Moisture Content to Corn Straw Returned to Field
摘要
Abstract
[Objective] Response of wheat growth and moisture status of lime concern black soil to rate of corn straw returned to field was conducted so as to seek the suitable amount.[Method] Five rates of corn straw 0, 1 500,3 000,4 500 and 6 000 kg/hm2 returned to field were designed and soil moisture content of 0-10 cm and 10-20 cm depth was analyzed in the main period of wheat growth, yield components were reviewed in wheat mature stage.[Result] There was a better accelerated effect of corn straw directly returned to field on wheat growth late season, seed yield increased by 3.49%-7.09%,averagely 4.94%, and the treatment of 3 000 kg/hm2 corn straw rate obtained the highest yield.Soil moisture content of 0-10, 10-20 and 0-20 cm improved obviously in the stage of jointing, booting and flowering so that the drought degree was alleviated.[Conclusion] The suitable rate of corn straw directly returned to field was 3 000 kg/hm2 at present production in lime concern black soil of Huaibei Plain.关键词
