李树是落叶乔木,对气候条件适应性强,易管理。近年来,北方各省推广用毛樱桃作矮化砧木的李树苗木,当年即可形成花芽,栽后二年见果,五年即可进入盛果期。因此在庭院育苗或栽树都可获得较高的经济效益。1.矮化砧木苗的繁育六七月间,采集成熟的毛樱桃果实,沤烂果肉,洗出种子,混入湿砂挖坑埋藏。翌春解冻,取出催芽。上年秋翻育苗地,耙压,早春整地施基肥,按实际需要做畦或做垄,春分至清明期间,开沟播种。
Li tree is a deciduous tree, adaptable to climatic conditions, easy to manage. In recent years, the northern provinces promote the plum trees with dwarf cherry as seedlings, and flower buds can be formed in those years. Seeing fruit two years after planting, it can enter the fruitful stage in five years. Therefore in the garden nursery or planting trees can get higher economic benefits. 1. dwarf rootstock breeding Breeding six or seven months, the acquisition of ripe cherry cherry fruit, rotten flesh, washed seeds, mixed with wet sand digging buried. The next spring thaw, remove the germination. In the autumn of last year, transplanting seedlings, raking pressure, early spring basal fertilizer, according to the actual need to do 畦 or ridge, during the vernal equinox to the Qingming ditch seeding.
