‘Q优1号’从2004年起在越南示范种植,2006年通过越南农业部审定,重庆中一种业有限公司每年向越南出口Q优1号杂交水稻种子100万kg。在越南种植表现出产量高、米质优、生育期短、适应性广等特点。栽培上宜适时早播,移栽40～45窝/m2,施肥实施"重底早追"原则,科学肥水管理,及时防治病虫害。
针对现有杂交水稻种子生产方式即将被集约化的种子生产方式所取代的趋势,2010年度开展了机械化育苗、插秧、赶粉等技术的探索,结果初步表明：杂交水稻制种生产全程机械化是可行的。制种生产全程机械化比目前大面积的常规生产每667m2节约成本421.5元,同等条件下增产6%～10%。

Diapause in insects is the adaption of insects to adverse living conditions in long-term evolving and environment selection to insects. This paper has discussed the influence of environmental factors which are photoperiod, temperature, moisture and food on induction of diapause in insects. Among all environmental factors, photoperiod and temperature are the most important in induction of diapause. Moisture effects induction of diapause mainly by changing photoperiod and temperature of the response, Food as an adjustment factor of insect together with photoperiod and the temperature induce diapause. Food also can be a direct impact on the growing of insect in the equatorial region when photoperiod and the temperature are rarely happened and changes.

To explore suitable application of nitrogen and phosphate fertilizer in rice production and methods of increasing absorption and use efficiency of N and P in rice plants, the experiment of nitrogen and phosphate levels was conducted in Bishan of Chongqing. The results showed that there was a parabola relationship between rice yield and the application rate of N, P fertilizer; The effect of soil/plant conditioner was remarkable in increasing absorption and use efficiency of N and P in rice plants. Under this experiment condition, the high yield was obtained in treatments which amounts of fertilizers and soil/plant conditioner application were as follows： 5.9 kg/667 m2 of nitrogen, 4.1 kg/667 m2 of phosphate, 5 kg/667 m2 of potassium and 33 kg/667 mE of soil/plant conditioner. Rational fertilization and application of soil/plant conditioner could obtained the high yield in rice varieties which great demand for nitrogen and phosphate fertilizer.
