摘  要：
采用田间试验和室内分析方法,研究了2017—2018年不同试验地3个水稻品种喷施不同浓度、用量、喷施次数植物营养剂对精白米必需氨基酸含量的影响。结果表明,植物营养剂的使用浓度从8.0%～16.0%均可提高精白米必需氨基酸含量。喷施11.0%植物营养剂,用量为61.875 kg/(hm~2·次),田间施喷植物营养剂溶液量562.5 kg/(hm~2·次),喷2次,精白米必需氨基酸含量达3 310.6 mg/100 g,比对照增加16.73%。喷施16%植物营养剂,用量为30.000 kg/(hm~2·次),田间喷施植物营养剂溶液量187.5 kg/(hm~2·次),喷2次,精白米必需氨基酸含量为3 156.6 mg/100 g,比对照增加10.96%,但在湘早籼45号上使用此浓度会产生灼伤斑。为节约成本、减少喷施工作量并最大限度地增加稻米必需氨基酸含量,实际应用中,植物营养剂的使用浓度以10%为宜,植物营养剂的用量以56.25 kg/(hm~2·次)为宜,田间喷施植物营养剂溶液量以562.5 kg/(hm~2·次)为宜,孕穗末期和齐穗期各喷施1次。

摘  要：
Field experiments and laboratory analysis methods were used to study the effects of spraying different concentrations, dosages and times of plant nutrients on the essential amino acid content in white rice from 2017 to 2018. The results showed that the essential amino acid content of rice was increased from concentration of plant nutrients 8.0%～16.0%. The application of 11.0% plant nutrient was 61.875 kg/hm~2 per dose, the application in the field was 562.5 kg/hm~2 per dose. The essential amino acid content of white rice reached 3 310.6 mg/100 g,which was 16.73% higher than that of the control. The application of 16.0% plant nutrient was 30.000 kg/hm~2 per dose, the application in the field was 187.5 kg/hm~2 per dose. The essential amino acid content of white rice reached 3 156.6 mg/100 g,which was 10.96% higher than that of the control,but burns were produced by using this concentration on Xiangzaoxian 45. In order to save cost, reduce spraying amount and maximize the content of essential amino acids in rice, in practical application, the concentration of plant nutrients is 10%, the dosage of plant nutrients is 56.25 kg/hm~2 per dose, the dosage of plant nutrients solution is 562.5 kg/hm~2 per time in the field, and it is sprayed once at the end of booting and full heading stages.
