摘要
通过对冬小麦8 种不同栽培方式的试验研究,从经济学产量和产投比的角度进行了分析比较,得出适合于渭北旱原冬小麦全生育期地膜覆盖穴播和膜侧条播栽培方式。其中冬小麦全生育期地膜覆盖穴播产量达2 856.0 kg/hm 2,膜侧条播产量2 638.5 kg/hm 2,分别较对照(露地平作)1 605.0 kg/hm 2 增产1 251.0 kg/hm 2、1 033.5 kg/hm 2,增产幅度达78.0% 和64.4% ,产投比分别达1.78 和1.90,比对照高出21.1% 和29.3% 。
In view of economic yield and the ratio of output/input,comparision of eight cultivating forms for winter wheat show that the film mulching and bunch seeding cultivation and the film mulching and double sides strip seeding are suitable for Weibei rainfed areas. Among them, this two forms increase yield by 1 251.0 kg/ hm 2 and 1 033.5 kg/hm 2 ,reaching up to 2 856.0 kg/hm 2 and 2 638.5 kg/hm 2 respectively. Compared with conventional cultivation, the percentage of increase gets to 78.0% and 64.4%. However, the ratio of O/I individually reach 1.78 and 1.90, which is 21.1% and 29.3% higher in comparison with the conventional cultivation.
