摘要
绿叶宝是新研制的一种高效叶面肥料。每个蚕期,用10—20ppm的绿叶宝溶液喷施桑树2次,可增产桑叶7.6％—20.0％,其增产幅度、稳定性均高于同类产品喷施宝、植宝18、多元复合微肥。用喷施过绿叶宝的桑叶养蚕,公斤桑产值提高3.6%,绿叶宝对蚕、人、畜无毒,且成本低、使用方便。1992年在10多个省区进行中试推广。
LUYEBAO is an effective and newly developed foliar fertilizer. Within each silkworm rearing season,twice applications at the concentration of 10 to 20 ppm on mulberry leaves result in an increment of leaf yield by 7-6% to 20. 0%.The stability and the scope of yield increment are both better than those of other foliar fertilizers tested,such as PENSHIBAO and ZHIBAO18, etc. Feeding silkworms with the mulberry leaves sprayed with LUYEBAO raise the output value per kg leaves by 3. 6%. It is safe to human beings, silkworms and livestock. Being low cost, effective and easy in application, it was tested and extended to mulberry gardens in more than 10 provinces/areas in 1992.
