目前,果树产量低而不稳的主要原因是果园土壤理化性能差,有机质含量低。果树秋季施肥,可提高土壤肥力,增强果树抗寒性,促使肥料中有机质充分腐烂分解,便于来年春季果树及时吸收利用。所以,果树秋季施肥是果树高产稳产的重要措施。 At present, the main reason for the low and unstable fruit tree production is that the orchard soil has poor physical and chemical properties and low organic matter content. Fruit trees fall fertilization, can improve soil fertility, enhance cold hardiness of fruit trees, promote complete decay of organic matter in fertilizers decomposition, to facilitate the next spring fruit trees timely absorption and utilization. Therefore, the autumn fruit tree fertilization is an important measure of high and stable yield of fruit trees.
