| Abstract: | The effects of different sowing dates from September to November on the plant height, tiller density, leaf density, proportion of withered and yellow leaves, fresh yield, dry yield and stem - leaf ratio of Lolium multiflorum in Fujian province were studied. The results showed that ： for varieties Maximus and Hercules, the suitable sowing date was from September to mid - October; under the condition of above sowing date, 5 - times clipping harvest in the whole growth period of each variety could be realized, stem - leaf ratio was less than 0.42, tiller density was more than 430/0.3 m2 , fresh yield was over 94 t/hm2, and dry yield was below 24.91 t/hm2. |
