为了探讨辽藁本对氮、磷、钾元素的吸收、分配规律以及辽藁本施肥的关键时期,较科学地确定氮、磷、钾三要素的分配方案、施用时期和施用方法,试验采用田间生长指标调查的方法对辽藁本营养元素的吸收积累与分配规律进行了研究。结果表明:辽藁本植株在进入营养生长期后,生长旺盛,对氮、磷、钾的需求量急增,尤其是磷、钾元素,此时的吸收量均达到全年的最大值;种子成熟后,辽藁本吸收氮肥较多。
In order to investigate the absorption and distribution of nitrogen, phosphorus and potassium and the key period of fertilization, the allocation, application and application of three factors of nitrogen, phosphorus and potassium were determined scientifically. Growth index survey method of Liao Tiao nutrition elements absorption and accumulation and distribution of the law were studied. The results showed that: After the Liaozhuo plant entered the vegetative growth period, its growth was vigorous, the demand for nitrogen, phosphorus and potassium increased sharply, especially phosphorus and potassium, and the absorption reached the annual maximum; the seed After maturity, Liao Tiao Ben absorbed more nitrogen.
