胡麻是我国主要的油料作物之一,作为一种抗旱、耐寒、耐瘠薄、适应性广的作物,广泛种植于我国北方的干旱、半干旱地区.垄膜集雨沟播种植作物技术是集垄沟种植、覆膜抑蒸、膜面集雨、宽窄行种植技术于一体的旱地作物增产栽培技术. 本文通过对旱地垄膜集雨沟播种植胡麻分别在播种量为 22.5、37.5 、52.5、67.5、82.5 kg/hm2的情况下与传统条播(CK)播量为75 kg/hm2的出苗率、生长量、农艺性状、产量等因素相比较,发现出苗率与播种量成负相关,胡麻生长量与播种量成负相关性.越到胡麻生长后期垄膜集雨沟种植对生长量的提高越明显.并明确旱地垄膜集雨沟播胡麻最适播种量为52.5 kg/hm2.

Flax is one of the main oil crops in our country,as a kind of drought,cold and barren resistance,a wide adaptability of crop,is widely grown in the arid and semiarid regions. In the north ridge membrane catchments ditch sowing cultivation technology is the collection ditch planting,coated or steamed,rainwater harvesting,spacing planting skill at the membrane surface in the integration of upland crops yield cultivation techniques. This article is to compare the seedling emergence,growth,agronomic characters,yield,etc. by different planting density respectively in the rate of 22.5,22.5,52.5, 67.5,82.5 kg/hm2 cases of ridge membrane catchments ditch seeding and conventional drilling (CK) on volume of 75 kg/hm2 . We find there are negative relationship between seedling emergence and seedling density,and between the growth and seedling density. There is significant improvement for growth in the end of season by measure of dry ridge film mulching. The best seeding density is 52.5kg/hm2 for Flax with dry ridge film mulching.
