定海县科委蒋长华,白泉片农技站张友旦、王贤仑、张渭清对本刊来稿,报导了磷肥在大麦生长中的作用。来稿说,目前随着水田大麦面积的扩大,在栽培技术上,也出现了一些难点,如播种后,总有一部分大麦生长很差,尽管在开春后继续进行氮肥培育,结果还是不行,最后只好耕掉。根据近年来各地报导,认为土壤酸性偏重是影响大麦生长的主要因素,然而近年来,发现不带酸性的土壤上也会出现类似的现象。他们通过试验和调查认为大麦生长差,缺磷是个重要因素。 Dinghai County Science and Technology Commission Jiang Changhua, Baiquan Tablet Farm Zhang Youdan, Wang Xianlun, Zhang Weiqing contribution to the publication, reported the role of phosphate fertilizer in barley growth. According to the manuscript, at present, with the expansion of the barley field in paddy field, some difficulties have also appeared in the cultivation techniques. For example, after sowing, some barley grows poorly. Although the nitrogen fertilizer cultivation continues after the spring, the result is still not good. Finally, Plow away. According to reports from various places in recent years, it is considered that soil acidity is a major factor affecting the growth of barley, but in recent years, similar phenomena have also been found in soil without acidity. They believe that barley growth is poor through experiments and investigations, and phosphorus deficiency is an important factor.
