冬闲田种植豌豆和蚕豆的生产及生态效益分析
Analysis of Productive and Ecological Effectiveness of Planting Peas and Broad Beans in Winter Idle Field
摘要
Abstract
Planting peas and broad beans overwinter can add green and reduce carbon dioxide,their fresh pods harvested in the following spring can supply products in the off-season vegetable market,their roots can fix free nitrogen,and their straw returned to the field can improve soil fertility,which has both productive and ecological effectiveness.In this study,the four cultivars of these crops were planted in the winter idle rice field in Dongxihu District of Wuhan City.The yield,photosynthetic characteristics,CO2 absorption,straw weight returning to the field,and their contents of N,P,and K were measured,comparing with the rape and milk vetch cultivated in the same period.The results showed that the yield and net income of pea cultivar WD-001 were higher than the others;the CO2 absorption amount of the broad bean cultivar 'YouzhiDabaipi' was the highest,reaching 941.32 kg/667m2 during the whole growth period,the N content(129.16 kg/667m2)in its returned straw was significantly higher than that of other cultivars except for milk vetch,the P content(53.30 kg/667m2)was slightly lower than that of milk vetch and rape,the K content(159.06 kg/667m2)was significantly higher than the other cultivars,which had a good carbon reduction effect and fertilizer potential.Therefore,planting peas and broad beans in winter idle fields has both good economic and ecological effectiveness,which is a new mode to make full use of the winter idle fields after the main crops are harvested.关键词
