通过对红花地膜覆盖栽培 ,以不铺膜为对照 ,对红花田间出苗率、发育状况、产量性状以及经济效益进行比较。结果表明 :(1)铺膜可使红花的田间出苗率提高 15 %左右 ,保苗株数提高 7%左右。 (2 )铺膜可使红花的各生育时期提前 ,干物质产量增加 4 9.15 %左右。 (3)铺膜可使子粒产量增产 5 1.6 %左右 ,花丝产量增产 30 .5 %左右。
Through the cultivation of safflower mulching film, compared with non-filming, the emergence rate, development status, yield traits and economic benefits of safflower field were compared. The results showed that: (1) The filming rate could increase the emergence rate of safflower in the field by about 15% and the number of seedlings in saplings by about 7%. (2) The filming can make safflower each growth period ahead of schedule, dry matter production increased by 4 9.15%. (3) Membrane can increase grain yield about 5 1.6%, filament yield increased about 30.5%.
