由沈阳农业大学研制的山楂丰收素,是由植物激素加山楂果实生长发育所必需的营养元素配制而成的。在山楂花期喷洒山楂丰收素,叶使花序坐果率提高31％,花朵坐果率提高128％,单株产量提高98％,果实成熟期提早10余天。同时,山楂百果重、果肉率也有提高。经喷施山楂丰收素的树,所结果实的呼吸强度降低、烂果率轻,这对延长贮藏期,保证果品质量,提高商品率,具有重要意义。
Developed by Shenyang Agricultural University hawthorn, is a plant hormone plus hawthorn fruit growth and development of the necessary nutrients formulated.
