俗话说:“四季施肥料,秋肥最重要”、“果树要高产,秋肥最关键”。这是很有科学道理的。因为,秋季临冬,经过近一年的“春华秋实”和地力消耗,果树生长和营养处于一年之中最弱的阶段,果树秋季生产后的营养补给、营养回流、果树越冬、抗旱抗寒、土壤保温保墒、土壤板结酸化的消解、地力恢复、土传病害的消除以及来年的枝芽萌发、开花结果、增产、提高品质,都依赖于秋季肥料的科学使用,依靠土壤健康和营养的有效供给;同时,秋收后正值多数果树根系的最后一次生长高峰,伤根容易愈合,病根容易修复,并可促发新根,提 As the saying goes: “Four seasons of fertilizers, autumn fertilizer most important ”, “fruit trees to high yield, autumn fertilizer the most critical ”. This is very scientific. Because the autumn winter, after nearly a year “Spring Harvest ” and the consumption of manpower, fruit tree growth and nutrition in one of the weakest stages of the year, fruit trees after the fall of nutritional supplements, nutrient reflux, fruit trees overwinter, drought resistance Cold, soil moisture and soil conservation, digestion of soil compaction acidification, ground recovery, elimination of soil-borne diseases and buds in the coming year germination, flowering, yield, improve quality, depend on the scientific use of fertilizer in the fall, relying on soil health and nutrition Effective supply; the same time, autumn harvest is the peak of most fruit trees the last growth peak, root injury easy to heal, easy to repair the root cause, and can promote new root, mention
