胡麻是我区的重要油料作物,近年播种面积约为300多万亩,占全国播种面积的三分之一左右。胡麻多分布在较瘠薄的旱坡地上,土壤肥力低,经营管理粗放,缺肥现象比较普遍,是低产的重要原因之一。 国内外对油用胡麻吸肥规律的研究资料较少。1978年我们曾在水肥水平较高的条件下测定胡麻对氮、磷、钾的吸收量及特点。结果表明:生产100斤胡麻籽实大约从土壤中
Flax is an important oilseed crop in our region. In recent years, the sown area is about 300 million mu, accounting for about one third of the sown area in the country. Flax is more distributed in the barren dry slope on the ground, low soil fertility, extensive management, lack of fertilizer is more common, is one of the important reasons for low yield. Domestic and foreign research on the rule of oil absorption of flax with less information. In 1978, we measured the amount and characteristics of nitrogen, phosphorus and potassium absorption of flax under high water and fertilizer levels. The results showed that: producing 100 pounds of flax seeds is about from the soil
