余甘,又名油甘,系大戟科,叶下珠属。果实鲜食先酸后甜,余味无穷,故而得名余甘。果实营养丰富,维生素C含量甚高。树体寿命长,速生,早产,丰产,病虫害少,耐旱,耐瘠,适应性强,用余甘绿化荒山,改善生态,保持水土,投资少,见效快,效益大,是山区治穷致富的有效途径之一.惠安县是余甘的主产县,栽培历史长,产量高,品质优。余甘繁殖,历史上,群众多利用野生余甘嫁接栽培品种。为了加速育苗,三年来,我们试用播种育苗嫁接,取得成效,生产出大量余甘苗。具体做法:(一)种子采集及处理 种子质量同成熟度关系很大。成熟特征是,果实转为浅黄色,果实变硬,种仁饱满、乳白色,置于水中会下沉,应及时采收。采来果实要用机械捣伤,再根据数量堆成长方形后用薄
More than willing, also known as oil Gan, Department of Euphorbiaceae, Phyllanthus. Fresh sour fruit after the sweet, endless aftertaste, it was named Yu Gan. Rich nutrition, high vitamin C content. Tree life is long, fast-growing, premature, high yield, less pests and diseases, drought, barren, adaptability, with green barren greening, ecological improvement, soil and water conservation, less investment, quick, effective, One of the effective ways.Hui’an County is the main producing county of Yu Gan, long cultivation history, high yield, excellent quality. More willing to reproduce, in history, the masses make use of wild more than grafted cultivars. In order to speed up the nursery, three years, we pilot sowing seedling grafting, and achieved fruitful results, to produce a large number of extra-plant seedlings. Specific practices: (a) seed collection and processing of seed quality is closely related with the maturity. Mature characteristics is that the fruit turned light yellow, hardened fruit, seeds full, milky white, placed in the water will sink, it should be timely harvesting. To adopt fruits to mechanical ramming, and then according to the number of heap into a rectangle after thin
