硼是果树生育不可缺少的元素之一,果树缺硼将会发生生理病害。朝阳地区果园土壤瘠薄,有机质缺乏。大部分果园土壤pH值在7.5～8以上,土壤水溶性硼偏低。果树缺硼较为普遍。又加上近年来严重干旱,许多缺硼严重的果园苹果发生缩果病,影响果树生产。为探讨硼肥在朝阳地区果树生产上的应用效果,我们于1981～1984年开展了硼肥对果树的应用效果试验。
Boron is one of the indispensable elements of fruit tree growth, fruit trees lack of boron will occur physiological diseases. Orchard soil in the Chaoyang barren, lack of organic matter. Most of the orchard soil pH value of 7.5 to 8 above, soil water-soluble boron is low. Boron deficiency is more common in fruit trees. Coupled with severe drought in recent years, many serious orchards lack of apple fruit shrinkage occurs, affecting the production of fruit trees. In order to explore the application effect of boron fertilizer on fruit tree production in Chaoyang area, we carried out the application effect test of boron fertilizer on fruit trees from 1981 to 1984.
