Experiment in Cold Water Irrigation of Low Critical Temperature TGMS Rice for High-yielding Multiplication |
| |
| Abstract: | The cold water irrigation is an effective way of multiplying the low critical temperature TGMS rice. The paper studied several key techniques in the multiplication of low critical temperature TGMS rice, the results showed that conducting cold water irrigation at Ⅳ～Ⅵ stage of young panicle differentiation of main spike or at Ⅲ～Ⅵ stage of young panicle differentiation of tillering spike, keeping at about 22℃ of water temperature at exit and spraying "920"to prolong spikelet's activity can obtain high yield. |
