为了探讨小麦对磷肥的适宜施用量,我们在坡马大队试验场安排了磷肥不同量作小麦底肥试验,现将试验总结于后。供试磷肥为过磷酸钙,分别亩施60斤,80斤、100斤、150斤和对照,五个处理。品种“郑州761”。在缺磷的地块,施用磷肥可以使小麦健壮生长分蘖增多,植株含磷量随施用量的增加而提高。从群体结构来看,以每亩施100斤的表现最好,年前分蘖76.9万株,春季分蘖达到94.9万株,成穗40.5万株,分别比对照增加16.4万株、19.6万株、6.1万株。单株成穗3.1个,比 In order to investigate the appropriate amount of wheat on the application of phosphate fertilizer, we Pok Brigade test site arranged for different amounts of phosphate fertilizer for wheat base test, the test is summarized later. Phosphate fertilizer test for the superphosphate, respectively, 60 kg Shi Shi, 80 pounds, 100 pounds, 150 pounds and control, five treatment. Variety “Zhengzhou 761”. In phosphorus-deficient plots, the application of phosphate fertilizer can increase the robust growth and tillering of wheat, and the phosphorus content of plants increased with the increase of application rate. From the point of view of group structure, the best performance was 100 kg / acre. The number of tillers was 769,000 and the number of tillers reached 949,000 and 400,000 per acre in spring, which increased 164,000 and 196,000 respectively, compared with the control Million. 3.1 per plant into ear, than
