| 摘 要： | 以云光109为材料,采用精确定量栽培技术、不同氮肥水平(B0、B1、B2、B3、B4、B5)与磷肥运筹(A1、A2)相结合,研究云光109叶长、剑叶SPAD值变化,并分析对其产量及结构的影响。结果表明,云光109在磷肥运筹A2时叶长顺序为倒2>倒3>倒4>倒1>倒5,在磷肥运筹A2各不同氮肥施用量的叶长、抽穗灌浆期剑叶的SPAD值大于磷肥运筹A1。通过不同氮肥水平与磷肥运筹措施,明确了云光109在生育后期施磷可以使其在抽穗期增加叶长,提高剑叶叶片的叶绿素含量,氮肥施用量为B3与磷肥运筹A2组合产量最高,达11.88 t/hm2。

| Abstract: | The experiment of different nitrogen levels(B0,B1,B2,B3,B4,B5) and phosphorus fertilizer managements(A1,A2) using precise and quantitative cultivation patterns in Yunguang 109 was carried out to study the effect of primary leaves leaf length,sword leaves SPAD and grain yield.Results showed that in phosphorus fertilizer management A2,the leaf length order was 2-3-4-1-5 from above,and it’s each leaf length and SPAD in heading filling stage were greater than that of A1.Through different nitrogen levels and phosphorus fertilizer managements,the later period fertilized phosphate in Yunguang 109 could increase photosynthetic leaves area and improve the chlorophyll content of sword leaf,and the yield of the combination B3 and A2 was the highest,11.88t/hm2. |
