施肥对新疆引进欧李生长及营养品质的影响

[目的]施肥对欧李生长及营养品质的影响.[方法]对野生欧李和山西选育的三个欧李品种的基肥、追肥、微肥的根施和叶面喷施处理以及果实营养成分分析.[结果]在肥力水平较高的试验地栽培,定植时不宜施基肥;叶面喷施氯化钙,可以提高野生欧李果实品质;根施氮、磷、钾肥可提高次年坐果率;从野生欧李中筛选出几株优良单株,经过果实品尝和营养成分分析,野生欧李的果实品质比选育的欧李品种好.[结论]欧李的根系发达,抗逆性强,果实营养价值很高,新疆引进欧李种植对干旱地区农业可持续发展有积极作用,具有广阔的应用发展前景.

Effect of Fertilizer Application on Nutritive Quality and Growth of Cerasus Humili

This paper studied changes of quality and growth of cerasus humili in fertilization.The results showed that it is not suitable to apply base fertilizer in planting the plant in rich fields;Sprinkling Calcium Chloride on the leaves of the plant could promote the quantity of the fruits;Using nitrogenous fertilizer,calcium phosphate and K fertilizer could raise the fruits rate in the following year.By tasting and measureing the nutritional composition of the ripe fruits,it was showed that the quantity of the wild seeding was better than that of varieties in Shanxi.It was meaningful in agricultureal production and woud good applied prospects that Chinese dwarf cherry was introduced in Xinjiang.
