Abstract: | Objective] To improve the unit yield level of rice in Longyang District, and to find the relationship between cultivated density and rice yield. Method] Under the condition of field plot test, effects of cultivated density on the yield and component factor were researched with Japonica rice Longke 16 as the test material.Result] Under 270 000-330 000 clusters/hm2 planting density and 540 000 -660 000/hm2 tillers, the yield of Longke 16 reached 11 250-12 000 kg/hm2 . Conclusion] Longke 16 is a high-yield Japonica rice variety with good com-prehensive traits.Rational cultivation and accurate planting can fully exert its potential of high yield. |
