摘  要:
硝酸稀土是我国农业生产中常用的稀土元素.本试验在苹果梨、早酥梨和锦丰梨上喷施不同浓度的硝酸稀土,研究硝酸稀土对不同梨树品种产量和品质的影响,结果表明:施用硝酸稀土能够极显著增加不同梨树品种的单果质量(p<0.01),并提高其增产率,当硝酸稀土浓度为0.05%时,3种梨树品种的单果质量和增产率达到最大.施用硝酸稀土对不同梨树品种可溶性固形化合物和果形指数影响不显著,但品种间差异显著(p<0.01),锦丰梨的可溶性固形化合物显著高于苹果梨和早酥梨(p<0.05),早酥梨的果形指数显著高于苹果梨和锦丰梨(p<0.01).

摘  要:
Rare earth nitrate is a rare earth element commonly used in agricultural production in China.In this experiment,the effects of rare earth nitrate on the yield and quality of different pear cultivars were studied by spraying different concentrations of rare earth nitrate on Zaosu pear,Pingguo pear and Jinfeng pear.The results showed that the application of rare earth nitrate could significantly increase the yield of different pear cultivars(p<0.01),and the yield of the three pear cultivars was the highest when the concentration of rare earth nitrate was 0.05%.The effect of rare earth nitrate on soluble solid compounds and fruit shape index of different pear cultivars was not significant,but the difference among cultivars was significant(p<0.01).The soluble solid compounds of Jinfeng pear were significantly higher than those of Pingguo pear and Zaosu pear(p<0.05),And the fruit shape index of Zaosu pear was significantly higher than that of Pingguo pear and Jinfeng pear(p<0.01).
