近年来,国内外市场梅果供不应求,价格不断上涨,各地梅树种植面积与日俱增。但由于管理水平较低,大多数梅园亩产只有150～200公斤。 氮磷钾是重要的营养元素,它们与梅树的生长发育和开花结实有密切的关系,在很大程度上控制着梅树的生长和产量。为此,我们研究了梅树花芽形成期(5～7月)枝叶中氮磷钾营养元素含量的变化和对氮磷钾营养的吸收状况,以便为生产中施肥提供理论依据。
In recent years, the demand for plum at home and abroad is in short supply, the prices are on the rise, and the planting area of plum trees is increasing day by day. However, due to the low level of management, most of the Meiyuan mu produce only 150 to 200 kg. Nitrogen, phosphorus and potassium are important nutrients, which are closely related to the growth and flowering and fruiting of plum trees, and largely control the growth and yield of plum trees. To this end, we studied the changes of N, P and K nutrient elements and the absorption of N, P and K nutrition in the branches and leaves of Plum flower bud formation (May-July) in order to provide a theoretical basis for fertilization in production.
