在植株生长的一定时期或整个生命周期,苹果树生物学产量的积累和组成,对于有目的地控制其生长和结果过程,有着重大的科学和实践意义。苹果树积累的生物学产量,是植株与外界环境复杂的相互作用的整体指标。苹果树的生物学产量首先取决子品种、砧木、水分和矿质营养成分的供给情况、栽植密度,以及太阳辐射能和其他因子对树体产生的影响. 为确定最适营养面积和施肥剂量,保证苹果树的最高生产率,1970年春在“克留连内”试验农场建立了试验园。深翻前,每公顷按下列剂量施肥:60吨腐植质+P300K
The accumulation and composition of the biological yield of the apple tree during certain periods of plant growth or throughout its life cycle is of great scientific and practical significance for the purposeful control of its growth and outcome processes. The biological yield accumulated by the apple tree is an overall indicator of the complex interaction of the plant with the external environment. The biological yield of the apple tree depends firstly on the availability of seed, rootstock, moisture and mineral nutrients, planting density, and the effect of solar radiation and other factors on the tree To determine the optimal nutrient area and fertilizer dose, The highest production rate of apple trees, the spring of 1970 in the “Ke Liu Liannei” experimental farm to establish a pilot park. Before deep plowing, apply the following doses per hectare: 60 tons of humus + P300K
