摘要
通过成苗数、苗期根系生长、有效收获株数、收获时主要经济性状及原茎产量的考查结果分析,认为免耕、免镇压等耕作方式对亚麻成苗数和苗期根系生长有一定的影响。但由于亚麻自身群体结构调控能力较强,各处理在收获时其有效收获株数、收获时主要经济性状及原茎产量差异不大。建议南方冬播亚麻生产区在土壤、气候条件适宜的情况下,可采用免耕、免镇压措施,降低种植亚麻的劳动强度和生产成本,促进农民种植亚麻的积极性,提高种植亚麻的经济效益。
According to the numbers of survived seedlings, growth of root system during seedling stage, numbers of stalks harvested effectively, main economic benefits and stalk yields, it is regarded that some cultivating methods such as non - plowing and non - covering under earth have some effects on the numbers of survived flax seedlings and the growing of root system during seedling stage. Because of flax group＇ s stronger structural self - modulation, different treatments have no obvious difference between the numbers of plants harvested effectively, main economic benefits and stalk yields. In order to decrease labor strength and production costs, and to enhance peasants ＇ enthusiasm of planting fax and increase economic interest, the two cultivating methods of non - plowing and non - covering can be applied in southern flax - planting zones in winter where the soil and climate are under a good condition for planting flax.
