摘要:

以粤晶丝苗2号为材料,开展不同比例有机无机肥配比试验,探究不同比例有机肥与无机肥配施条件下水稻的生长情况,以筛选出最佳施肥方案,进而获得高产水稻生长模式。结果表明,水稻在T3处理(有机肥11 250 kg/hm2,尿素169.8 kg/hm2,过磷酸钙468.75 kg/hm2,氯化钾187.5 kg/hm2)下的茎蘖数、总穗数、千粒重、结实率和产量等指标均达到最大值,且总穗数、千粒重、产量显著或极显著高于其他处理,是本试验条件下的最佳比例。

Abstract:

In order to explore the effects of different ratio of organic fertilizer and inorganic fertilizer on growth and yield of rice, select the optimum mix ratio, an experiment was carried out with Yuejingsimiao 2 as material. The results showed that the tiller number,total panicle number, 1000-grain weight, seed setting rate and yield of T3 treatment were the highest, and the total panicle number, 1000-grain weight and yield were significantly higher than the other treatments. T3 treatment was the best proportion in this test.

Key words: rice, organic fertilizer, inorganic fertilizer, growth, yield
