一、调节和增加树体营养 1.增加树体营养。一是秋施基肥,采用环状沟施入,一般树冠外围挖深50厘米、宽40厘米。这时秋梢停止生长,正是养分积累、根系旺长期,断根愈合快,还可长出一段新根,另外肥料也因当时温度高而易于分解可被晚秋或来春充分吸收利用。二是要防止早期落叶,保持秋季叶片完好。三是要调整果实负载量,适期采收。结果过多,会消耗大量的树体养分,不利于贮存营养的积累。因此,调整果实合理负载,也是提高树体贮营养水平的重要技术措施。
First, adjust and increase tree nutrition 1. Increase tree nutrition. First, autumn base fertilizer, the use of annular ditch into the general crown dug 50 cm deep, 40 cm wide. At this time autumn shoots to stop growing, it is nutrients accumulation, root long-term root pruning heal fast, but also grow a new root, the other because of the high temperature and easy decomposition can be late autumn or spring full absorption and utilization. The second is to prevent early deciduous, keep the autumn leaves intact. The third is to adjust the fruit load, the appropriate harvest. The result is too much, it will consume a lot of tree nutrients, is not conducive to the accumulation of stored nutrients. Therefore, adjusting the reasonable fruit load is also an important technical measure to improve the nutrition level of tree storage.
