地膜覆盖对油用亚麻干物质积累、经济效益的影响
Effects of Plastic Mulching Film on Dry Matter Accumulation and the Economic Benefit of Flax
摘要
Abstract
A field experiment was conducted to study the effect of uncovering film at different stage on dry matter accumulation and the economic benefit of flax.Results indicated that,the film covering treatments(A-D)can significantly increase dry matter accumulation during the period from seedling to green fruit.The increasing proportion was 49.0％ 、36.27％ 、39.22％ 、60.78％,respectively.The treatment of uncovering film at the 40th day was the highest among the film covering treatments (A-D),reaching 1.02 g per strain.Economic benefit analysis showed that A treatment had the best economic benefit which was,increased by 3266.8 yuan/hm2 compared with CK.In summary,the treatment of uncovering film at the 40th day is the most appropriate time for high yield of flax.关键词
