| 摘 要： | 研究了稻草还田对免耕水稻根系生长和产量的影响.结果表明,稻草还田可显著提高免耕水稻产量,显著或极显著提高单株根系干重、单株生物鼍、根半径、单株根表面积、单株根长、单条根长、根长密度、根系活力及超氧化物歧化酶活性,但是对单株总根数的影响不大.与3 t/hm<'2>稻草还田量相比,6 t/hm2稻草还田量的增产效果和对根系生长的促进作用更大. |

| Abstract: | The effects of straw incorporation on root growth and grain yield under no-tillage of rice were studied.The results showed that grain yield increased significantly and root dry weight per plant,biomass per plant,root radius,root area per plant,root length per plant,average root length,root length density,root activity and SOD activity increased significantly or very significantly with straw incorporation under no-tillage.However,there was not a significant effect of straw incorporation on the number of root... |
