Agronomic cultivation measures on productivity of oilseed flax: A review

Oilseed flax is one of the most important oil crops in China. With the improvement of people's living standards and the deepening knowledge of the nutritional value of oilseed flax, the demand and economic value of oilseed flax are increasing, and the cultivated area in China is expanding. However, the grain yield of oilseed flax is lower than other oil crops. It varies significantly from year to year, combined with a lower degree of mechanization, which has greatly limited the healthy development of the flax industry. Some of the effects of agronomic measures on productivity and water use efficiency of oilseed flax are reviewed in this paper. The major agronomic strategies for the productivity of oilseed flax were presented based on fertilization, plant density, irrigation, cropping pattern and weed control. Future research should investigate the effect of silicon and potassium fertilizers on the mechanism of lodging resistance of oilseed flax, the effects of diversified cropping systems (strip intercropping and crop rotation) on high and stable productivity and efficient utilization of resources.
