本文研究了营养物质在果实中的分配以及年份条件,果树品种,土壤类型和施肥对果实营养物质获取量的影响。现已查明,在灰色灰化土壤上,果实种子内磷素的含量取决于土壤肥力。在幼龄果园,树体的生长量取决于营养物质的获取量。1972—1974年,我们在乌兹别克森林草原地区的于木列耶夫果树栽培试验站进行了苹果施肥的田间试验。供试土壤为普通黑钙土和灰色灰化土。用科尔达尔方法测定植株内氮的含量,用列夫兹科依变体比色计测定磷的含量,而钾的含量则借助于火焰光度计进
In this paper, the distribution of nutrients in fruits and the effects of year conditions, fruit tree varieties, soil types and fertilization on fruit nutrient acquisition were studied. It has been found that the content of phosphorus in fruit seeds depends on soil fertility on gray ashed soil. In young orchards, the amount of tree growth depends on the amount of nutrients that are harvested. In 1972-1974, we conducted a field trial of apple fertilization at the Yuluyevu Fruit Cultivation Station in the Uzbekistan Forest Steppe. The test soil is ordinary black earth and gray ashes. The content of nitrogen in plants was determined by the method of Kordal, the content of phosphorus was determined by Levzko Variant Colorimeter, and the content of potassium was determined by means of flame photometer
