1988～1989年在平原沙壤土地上以3年生晚熟桃为试材,进行了土施和树上喷布PP333试验。结果表明,土施0.5g/m2和1.0g/m2PP333,对桃树生长有明显的抑制作用并能促进花芽形成,250ppm液喷二次的效果与土施0.5g/m2相当。但处理后第二年土施。0.5g/m2的作用大大下降,喷布处理树的长势
From 1988 to 1989, perennial perennial peach was used as test material on sandy loam soil in plain area, and soil and tree spraying PP333 was conducted. The results showed that soil application of 0.5g / m2 and 1.0g / m2PP333 could significantly inhibit the growth of peach trees and promote flower bud formation. The effect of spraying 250ppm liquid twice was equivalent to 0.5g / m2 soil application. But the second year after the treatment of soil facilities. 0.5g / m2 greatly reduced the role of spray processing tree growth
