摘要
宽幅麦套花生与小麦有较长共生期,其生长发育有前期晚发、后期缓降和中期猛增的特点。生育中期猛增是干物质累积的关键,此阶段(始花后80天)中所累积的干物质量,占全生育期累积总量的87.6％,是转换成经济产量的基础。在收获前40天内荚果增长量,占荚果产量的68.6％。采取用养结合集约耕作施肥一体化;良种配套充分利用光热资源;改变种植方式发挥边际优势;规范种植;早套覆膜严把播种质量关;根据生长特点加强促保管理等配套技术,实现小麦花生双300—400公斤。
Regularity of growth and development of peanut inrerplanted in wide bed wheat field and the techniques for double high yields of both wheat and peanut were studied during 1987-1989.Because of a longer symbiotic growth stage with wheat,the growth and development of interplanted-peanut showed the characteristics of raising slowly in early glowing stage,increasing sharply during middle growing stage and decreasing gradualy in late growing stage.Rapid increase of vegetative growth during middle growing stage was the key stage of dry matter accumulation.The amount of accumulative dry matter within 80 days( 20-100 days after flowers emergence)made up 87.6% of its total dry mass.Swift increase of reproductive development was the foundation of economic yield for-mation The accamulative amount of pod dry matter,40days before harvest made up 68.6% of peanut (pod)yield.Five item measures were necessary for double yields of 300-400kg per mu for both wheat and peanut.
