| 中文摘要: |
| 在关中棉区大田条件下,采取不同种植密度下控制供水的方法,研究了灌水和密度对转基因抗虫棉生长发育、干物质分配及产量的影响。结果表明,灌水和密度对棉花生长具有双向调控功效,二者优化高效组合是灌水675 m3/hm2,密度4.57.5万株/hm2,比CK增产21.6%23.6%,灌水效率达2.493.19 kg/m3。 |
| 英文摘要: |
| The effect of irrigation plant density on the development,dry matter distribution and yield of transgenic insect-resistant cotton was studied with the method of controlling irrigation and different plant density under farm condition in the middle cotton belt of Shaanxi Province.The results showed that irrigation and density had two-way regulated effect on the development of cotton.The optimum composition of both measures was irrigation in 675 m3/hm2 and density in 4.5～7.5×104 plant/hm2.In this case,the yield was increased by 21.6%～23.6% over that of CK,and the irrigation efficiency got 2.49～3.19 kg/m3. |
