晚稻施用“红四方”控释肥料田间效果试验

通过晚稻小区试验和大田示范试验,研究了"红四方"控释肥对晚稻作物生长的影响。结果表明,与施用常规肥料相比,"红四方"控释肥有利于改善晚稻的经济性状,如株高、有效穗数、穗实粒数和千粒重,分别提高1.31 cm、0.18万株/667m~2、2.17粒/穗和0.41 g;施用控释肥与常规肥相比,稻谷平均增产59.49 kg/667m~2,增产率为15.8%,增加纯收入70.84元/667m~2。且控释肥优于复合肥,施用"红四方"控释肥料与施用复合肥相比较,平均稻谷增产31.16 kg/667m~2,增产率为7.71%,增加纯收入39.3元/667m~2。

Field Effects of"Red Quartet" Controlled Release Fertilizer on Late Rice

A plot experiment and a field demonstration experiment have been conducted to study the "Red Quartet" effects of the controlled release fertilizer on the growth of late rice. The results showed that compared with conventional fertilizers, "Red Quartet"controlled release fertilizer is beneficial to improve the economic traits of rice, such as plant height, effective panicles, grain number per ear and 1000-grain weight, which increased 1.31 cm, 2.7million plants/hm2, 2.17 grains/spike and 0.41 g respectively. Moreover, the average yield increased by 892.35 kg/hm2, the increasing rate was 15.8%, and net income increased by 1062.6 yuan/hm2 (RMB). The controlled release fertilizer is better than the compound fertilizer, the application of "Red Quartet" controlled release fertilizer created average yield increase of 467.4 kg/hm2, 7.71% increasing rate, and pure income increased 589.5 yuan/hm2 (RMB).
