了解胡麻对主要肥分氮磷钾的吸收数量与需肥特点,对指导合理用肥有着重要的作用。为此,我们在呼市郊区的水浇地上,对高产胡麻的需肥特点与数量进行了研究,结果如下。一、胡麻对主要肥分的吸收数量胡麻籽实较小,但脂肪含量达30—47%,蛋白质含量在 Understanding flax on the main fertilizer points to absorb the amount of nitrogen, phosphorus and potassium characteristics and needs of fertilizer, to guide the rational use of fertilizer has an important role. Therefore, on the irrigated land on the outskirts of Hohhot, we studied the characteristics and quantities of fertilizer required for high-yield flax. The results are as follows. First, flaxseed on the absorption of the main amount of fat Flaxseed is small, but the fat content of 30-47%, the protein content of
