摘　　要：为了研究叶面喷施富硒水溶肥对水稻产量及稻米含硒量的影响。设置5个处理,分别为CK(对照)、A、B、C、D处理,每个处理均进行3个重复,每个重复按30 m^(2)进行区组随机排列。对照组(CK)喷施50 kg清水;处理A喷施14 g硒肥+50 kg清水;处理B喷施22 g硒肥+50 kg清水;处理C喷施30 g硒肥+50 kg清水;处理D喷施38 g硒肥+50 kg清水,待水稻成熟后对其产量性状和水稻籽粒的硒含量进行测定。结果发现:对照组(CK)和其他处理在株高、穗长、穗总粒数、穗实粒数、结实率和千粒质量上差异不显著;理论产量(kg/667 m^(2))以处理C最高,显著高于其它处理;籽粒的硒含量,处理D>C>B>A>CK;处理D的硒含量显著高于其它处理。综上所述,说明叶面喷施水溶性富硒水溶肥可以提高水稻的产量,同时提高稻米的硒含量。综合考虑,30 g硒肥+50 kg清水/hm^(2)的喷施量最适宜水稻种植。To investigate the impact of foliar application of selenium-rich water-soluble fertilizer on rice yield and selenium content in rice grains,five treatments were set up:CK(control),A,B,C,and D.Each treatment was replicated three times,with each replicate arranged in a randomized block design covering 30 square meters.The control group(CK)received a spray of 50 kg of water.Treatment A involved spraying 14 g of selenium fertilizer plus 50 kg of water;Treatment B,22 g of selenium fertilizer plus 50 kg of water;Treatment C,30 g of selenium fertilizer plus 50 kg of water;and Treatment D,38 g of selenium fertilizer plus 50 kg of water.After the rice matured,its yield characteristics and selenium content in the grains were measured.There were no significant differences in plant height,panicle length,total grains per panicle,total grains per panicle,seed setting rate,and thousand grain weight between the control treatment(CK)and each treatment;The theoretical yield of 667 m^(2) was highest in treatment C,significantly higher than other treatment;The selenium content in seeds was treated with D>C>B>A>CK;The selenium content in treatment D was significantly higher than that in other treatments.Conclusion:In summary,foliar spraying of water-soluble selenium rich water-soluble fertilizer can increase rice yield and selenium content.Taking all factors into consideration,the optimal spraying rate is 30 g selenium fertilizer+50 kg clean water/hectare.
