摘　　要：为探明以氨基酸和腐殖酸为有机质来源的含有机质叶面肥对水稻生物量、农艺性状及产量的影响,共设置5种处理:不含有机质对照(CK)、氨基酸125 g/L(T1)、氨基酸110 g/L+腐殖酸20 g/L(T2)、氨基酸95 g/L+腐殖酸40 g/L(T3)、氨基酸80 g/L+60腐殖酸g/L(T4),处理T1~T4有机质含量均为100 g/L。以水稻品种“内5优39”为试验材料,在孕穗期稀释600倍进行喷施。并测定水稻4个关键生育期的生物量积累,收获期的株高、叶绿素、有效穗数、结实率和产量。结果表明,在水稻孕穗期喷施各处理,均可促进水稻生物量积累,提高农艺性状,并增加产量;且随着氨基酸添加量的降低,腐殖酸含量的增加,各项指标呈先增加后降低的趋势。其中氨基酸95 g/L+腐殖酸40 g/L处理与其他处理差异达显著水平。有机质配比为氨基酸95 g/L+腐殖酸40 g/L,水稻农艺性状、产量等增加幅度最高,推荐在水稻孕穗期喷施。The study aimed to find out the effect of folìar fertilizer with organic matter between amino acids(WSA)and humic acid(HA)on biomass,agronomic traits and yield of rice.There were five treatments:CK(no organic matter),WAS 125 g/L(T1),WAS 110 g/L+HA 20 g/L(T2),WAS 95 g/L+HA 40 g/L(T3),WAS 80 g/L+HA 60 g/L(T4).The contents of organic matter were 100 g/L from T1 to T4.Rice variety“5 you 39”was used as the test material.The treatments were sprayed in diluted 600 times at booting stage.The biomas accumulation at the key growth stages of rice,and the plant height,chlorophyll,effective panicle number,seed setting rate and yield at harvest time were detected.The biomass accumulation,agronomic characters and yield of rice could be promoted by spraying all treatments at booting stage.Moreover,with the decrease of WSA and the increase of HA,each index showed a trend of increasing at first and then decreasing in the end.The treatment of WAS 95 g/L+HA 40 g/L was significantly different from other treatments.The ratio of organic matter was WAS 95 g/L+HA 40 g/L with the highest increase in agronomic characters and yield.It was recommended to spray rice at booting stage.
