【摘要】 随着国家惠农政策增加,西藏养殖业发展迅速,饲草问题凸显。为解决饲草问题,各地农业科技工作者在不断地思考和探索。通过引进超深旋犁耕作创新耕作技术,研究对青贮玉米生产和产量的影响发现,在覆膜的条件下,该技术对青贮玉米的出苗率和生育期等没有影响,但可使茎粗增加15.3%,持绿叶片数增加15.5%,产量增加10.1%。通过综合经济效益分析,实施该项技术,每667 m2可以增加经济收入302.17元。更多还原

【Abstract】 With the increase of the national policy of benefiting farmers,the breeding industry in Tibet has developed rapidly,and the problem of forage grass has become prominent. In order to solve the forage problem,agricultural science and technology workers in various places are constantly thinking and exploring. In this experiment,the effect of ultra deep rotary plough on the production and yield of silage maize was studied. It was found that under the condition of plastic film mulching,the technology had no effect on the emergence rate and growth period of silage maize,but it could increase the stem diameter by 15.3%,the number of green leaves by 15.5% and the yield by 10.1%. Through comprehensive economic benefit analysis,the economic income can be increased by 302.17 yuan per 667 m~2.更多还原
