| 摘 要： | 大山楂对土壤的适应性很强,能耐水涝5～7d以上,还耐pH=8.75～9.02,返碱重,土壤含Na_2CO_3和NaHCO_3表层为0.015％～0.250%及下层为0.0028％～0.0081％的条件,在同一条件下山楂在生长、结果等方面均较正常,更好于苹果和梨.在pH=8.75～9.02条件下,pH8.75的地块生长结果等方面又明显好于pH9.02的地块,在此条件下,如果光照不足,则生长结果等表现不良,其不良作用大于土壤不良的危害。

| Abstract: | Experiments (1989-1991) were made on the effect of the high pH of soil,waterlogging and pernicious calt of oil of orchard on the growth and producting ofhawthorn. The result indicated that normal growth, flowering and roducting of thetree can maintained under those conditions (1) Waterlogging 5～7days; (2). pH8.75-9.02 in year ycle, 3).Na_2 CO_3 and NaHCO_3 0.015%～0.025% in surface layer of soil andNa_2CO_3 and NaHCO_3 0.0028%～.0081% in bottom layer of the soil. It is said that Haw-thorn tree resisit more than other pome fruit (apple and pear ree), the growth andproducting of hawthorn tree in pH8.75 appears to be better significantly than those inpH9.02. nder the soil condition of the experiment the sunlight deficit could have aharmful effection on the growth and roducting of the tree. |
