李树原产我国,分布很广,栽培历史悠久。它具有进人结果期早、成熟早、见效快、供应期长、适应性强、栽培管理容易、树体矮、宜密植等特点。同时它的营养价值和经济价值也都很高。我省由于重视不够,李树栽培面积较少,产量较低,不能满足市场的需要。为了促进我省李树生产的发展,现把适宜在我省栽培的优良李树品种介绍如下。1 绥李3号 9月上旬成熟。树势强,树姿较直立,成枝力强。果实圆形,平均单果重60克,果实底色黄绿、熟后紫红色、被有白色果粉,果肉黄色、汁多、味香甜、纤维少,核小,粘核,较耐贮运,品质上等。栽植后2～3年可开花结果。抗寒,丰产,在多雨年份或低洼地栽植稍有裂果现象。2 北方1号(绥陵江)8月上旬成熟。树势强,树姿直立,半开张,成枝力强。果实圆形,平均单果重34.5克,果实底色黄绿、复粉红色,果肉黄色、厚而多汁、味香甜,核小、粘核,品质上等,但皮薄不耐贮运。较抗寒、个别年受冻伤后恢复力强。抗红点病,采前不落果,较丰产。我省南部地区可低接栽培,中部地区应高接栽培,
Li Shu origin of our country, is widely distributed, cultivation has a long history. It has entered the early results, early maturity, quick, long-term supply, adaptability, cultivation and management is easy, short trees, should be close planting and so on. At the same time its nutritional value and economic value are also high. Due to insufficient attention in our province, Li cultivated less area, lower yield, can not meet the needs of the market. In order to promote the development of plum tree production in our province, we now introduce the fine plum tree species suitable for cultivation in our province as follows. 1 Sui Li 3 early September mature. Strong tree, tree posture more upright, strong branch. The fruit is round with an average fruit weight of 60 grams. The fruit is yellow-green in color, purple in cooked fruit, white fruit powder, yellow in fruit pulp, juicy in taste, sweet in taste, few in fiber, small in nuclear, sticky kernel, First class. 2 to 3 years after planting can flowering results. Cold, high yield, in the rainy years or low-lying planting a slight crack phenomenon. 2 North No. 1 (Suiling River) mature in early August. Strong tree, tree posture upright, half-open, strong branch. The fruit is round with an average fruit weight of 34.5 grams. The fruit is yellow-green in color, pink in color, yellow in fruit, thick and juicy, sweet in taste, small in nucleus and sticky in core. More cold, individual years after the frostbite resilience. Anti-red dot disease, no fruit before harvest, a more productive. The southern region of our province can be low-take cultivation, the central region should be high-take cultivation,
