| 摘 要： | 采用亚硫酸氢钠、白砂糖、尿素、磷及二氢钾等化学药剂及营养物质配合使用，对茎用莴苣进行叶面喷施。试验结果表明：用１５０ｐｐｍ的ＮａＨＳＯ３配以０．２％的白糖、０．２％的尿素、０．２％的ＫＨ２ＰＯ４进行叶面喷施效果最好，能增产２０．２２％，其中各种喷施物对产量影响白大到小的顺序依次为ＮａＨＳＯ３＞白糖＞尿素＋ＫＨ２ＰＯ４，Ｎ／Ｋ比例明显影响有机物的分配和嫩茎的生长情况．

| Abstract: | in this paper,we have adapted sodium sulphite granulated sugar.urea.potassium phosphate to coordinate and apply for the leaves of asparagus lettuce.It make clear:Using 150ppm sodium sulphite +0.2% granulated sugar +0.2% urea +0.2% potassium phosphate is the best answer for increasing output by over 20. 22 per cent The order from big to small about the effect is NaHSO3>granulated sugar>urea +KH2PO4; The proportion of N/K obviously influence the distribution of the organic substance and the tender stem's growth of asparagus lettuce. |
