Demonstration Summary Of The High Photosynthetic Efficiency Cultivation Of Rice In Antu County

At present, how to improve the yield of rice has become one of the major problems needed to resolve in the world. The rice planting angle from the north and south to change for South West 19 degrees 57 minutes, the traditional 30cm isometric changed to 50 cm and 20 cm combination spacing of new cultivation technology demonstration and extension of the results, adjust to and narrow and wide with high photosynthetic efficiency of new cultivation techniques, yield region three point average yield than conventional planting structure increased by 15.2%, production first is three points of 1000 grain weight were increased, the average increase rate was 13.3%, and the second is to increase the panicle number, the average increase rate is 11%; three points have increased is reducing the unit Area effective spike number per plant and seed setting rate. Improve the weight that is high efficiency model cultivation techniques to adjust the increased the late photosynthetic rate, reduce the empty flat rate, enhanced the 1000 grain weight, spike number per unit area increases is high efficiency model cultivation techniques of wide narrow row mode for tiller development. At present, Antu county promotion high efficiency new cultivation technology promotion area of 1400 hectares, average per unit area yield than conventional planting increased 1000 kg/hm2.If further play high photosynthetic efficiency of new cultivation techniques of yield potential and high photosynthetic efficiency of new cultivation techniques of area to expand, to farmers bring benefits, need to be further studied in high efficiency new cultivation technique under the condition of suitable varieties, the optimum fertilization technology system and other agronomic measures of variable factors; the need to redesign paddy pool ridge direction of basic construction.
