平衡施用有机肥对有机稻产量及构成因素的影响

Effects of Balanced Fertilization of Organic Fertilizer on Yield and Component Factors of Organic Rice

[目的]采用不同有机肥配方,探索有机肥平衡施用效果,以提高有机稻生产水平。[方法]采用随机区组设计,检测不同有机肥配方的施用效果。[结果]在稻鸭共作模式下,平衡施用有机肥对水稻产量以及单位面积穗数有显著影响,但对每穗粒数、结实率和千粒重的影响较小。[结论]试验基地采用施用"水稻秸秆堆肥15 000 kg/hm2+菜籽饼1 500 kg/hm2+鸡粪750 kg/hm2"的有机肥配方,有机稻产量达到6 200 kg/hm2,说明平衡施用有机肥可以提高单位面积水稻的产量。

[Objective] In order to improve the production level of organic rice,the effects of balanced fertilization of organic fertilizer were studied with different organic fertilizer formulas.[Method] Randomized block design was adopted to study the application effect of different organic fertilizer formulas.[Result] Under rice-duck integrated farming system,balanced fertilization of organic fertilizer had the obvious effects on the rice yield and ear number per unit area,but had litde effects on number of grain per ear,maturing rate and thousand seed weight.[Conclusion] The organic fertilizer formula of rice straw compost 15 000 kg/hm2,rape seed cake 1 500 kg/hm2 and chicken manure 750 kg/hm2 was used in the test base.And the yield of organic rice reached 6 200 kg/hm2,which showed that the balanced fertilization of organic fertilizer could improve the rice yield per unit area.
