THE EFFECT OF “LIANG-FENG-SU”ON INCREASING PRODUCTION OF SWEET POTATO

摘要: <正> 一、前言随着科学技术的发展,植物生长调节剂的开发应用已同农药、化肥一样,日益成为一项促进农业增产的重要措施。为此,山东省化工厅组织济宁农药厂研制生产了一种新型植物生长调节剂——粮丰素。其化学活性成分为五苯氧乙酸与微量元素的络合物,总含量为2％。为无色、无味、无毒水溶液。常温下稳定性好。该产品对根茎类作

Abstract: Treating sweet potato seedling with 33×10~(-6) "Liang-Feng-Su", by means of phosphorus-32 and carbon-14 tracing technique showed that the use of "Liang-Feng-Su" not only increased the root vigor and net photosynthetic efficiency of leaves, but also promoted the transport of photosynthate to root tubers which results in economic benefit.
