摘要
在辽西北地区覆膜条件下,试验了大粒、小粒花生的单粒与双粒适宜播种密度。试验表明:大粒单粒适宜播种密度9 900株/667m^2,可比双粒节约用种0.51 kg/667m^2,节约成本5.1元/667m^2,增加产量8 kg/667m^2,增加效益48元/667m^2,合计节本增效53.1元/667m^2。小粒型花生单粒适宜密度15 500株/667m^2,可比双粒节约用种1.746 kg/667m^2,节约成本17.46元/667m^2,可提高产量11 kg/667m^2,增加效益66元/667m^2,合计增加效益83.46元/667m^2;大粒型花生双粒适宜播种密度10 500株/667m^2,小粒型花生双粒播种适宜密度17 500株/667m^2。
Under the conditions of film in Liaoning region. through the large particles,Small-sized peanut seed and two-grains seeding suitable density study,to reduce the planting density,play individual production performance. Tests show that： Large grain single seed suitable for planting density of 9 900 plants/667 m^2,can save the use of 0. 51 kg,saving costs 5. 1 yuan,increase production 8 kg,increase efficiency of 48 yuan,the total cost of 53. 1 yuan. Small-sized peanut individual grain suitable density of 15 500 plants/667 m^2,can save the use of 1. 75 kg,cost savings of 17. 46 yuan,can increase the yield of 11 kg,increase efficiency of 66 yuan,the total efficiency of 83. 46 yuan; Large grain peanut seeds suitable for planting density of 10 500 plants/667 m^2,Small-sized peanut seeding suitable density of 17 500 plants/667 m^2.
