摘要：

为明确生物炭施用量对垦粳5号产量及品质的影响，设置单因素完全随机试验。结果表明，生物炭施用量为7 500 kg/hm2时，水稻产量最高，达13.90 g/丛，极显著高于对照；有效穗数为13.86穗/丛，比对照高16.86%，差异极显著；籽粒蛋白质含量最低为6.5%，较对照低2.56%，食味评分值最高为87.6分，比对照高1.04%。整精米率各施生物炭处理均高于对照，其中，生物炭施用量为16 500 kg/hm2时最高，比对照高7.09%。生物炭施用量为12 000 kg/hm2时，垩白度、垩白粒率最低，分别为7.30%和13.90%，分别较对照低28.76%和20.11%。本试验条件下，7 500 kg/hm2是生物炭适宜的施用量。

Abstract:

In order to explore the effects of biological carbon on yield and quality of Kenggeng 5, a single factor complete random test was designed. The results showed that when the amount of biological carbon was 7 500 kg/hm2, the yield of rice was the highest, up to 13.90 g per hill, which was significantly higher than the control; the effective panicles were 13.86 per hill, which were significantly higher than that of the control; the protein content was the lowest, which was 2.56% lower than the control, and the taste score was the highest, which was 1.04% higher than the control. The head rice rate of all treatments was higher than that of the control, and when the amount of biological carbon was 16 500 kg/hm2, the head rice rate was the highest, which was 7.09% higher than the control. When the amount of biological carbon was 12 000 kg/hm2, the chalkiness degree and chalky rice rate were the lowest with 7.30% and 13.90%, respectively, which were 28.76% and 20.11% lower than the control. The yield, effective panicles, grain number per panicle, seed setting rate, head rice rate and taste score of rice were increased when the application of biological carbon was 7 500 kg/hm2.
