喷施适量的稀土溶液,对多种果树都有10～30％增产幅度。同时坐果率和果实品质都有明显提高。 稀土在果树整个生长发育期均可施用。最佳施用期是在果树生长的主要物候期之前。如花期、果实膨大期之前施用,以每年喷施2—3次为好。适宜的浓度能有效的促进果树生长发育,浓度过高,则起抑制作用。适宜浓度一般为300～800ppm。溶解稀土时可适 Spraying an appropriate amount of rare earth solution, a variety of fruit trees have 10 ~ 30% yield increase. At the same time, the fruit setting rate and fruit quality have obviously improved. Rare earth can be applied throughout the growth and development of fruit trees. The best period of application is before the main phenology of fruit trees. Such as flowering, fruit enlargement before the application, spraying 2-3 times a year as well. Appropriate concentration can effectively promote the growth and development of fruit trees, the concentration is too high, it plays an inhibitory effect. Appropriate concentration is generally 300 ~ 800ppm. When dissolved rare earth may be suitable
