合理施肥是集约果园栽培技术的重要环节。提高农技措施效果使其满足果树的无机营养以取得稳产高产、改进果实品质密切相关。 1975年,我们在《米哈依洛夫山口》果树国营农场设置了田间试验,研究增施N,P,K肥量对苹果短枝型品种新红星的影响。1972年秋天栽植一年生苗,营养面积5×4米,砧木为苹果栽培品种实生苗。试验是按B·H·彼列古多维在全苏Д·Н·
Rational fertilization is an important part of intensive orchard cultivation techniques. Improve the effectiveness of agricultural measures to make it meet the fruit tree inorganic nutrition in order to achieve stable and high yield, improve fruit quality are closely related. In 1975, we set up a field experiment at the Fruit Tree Farm of “Mikhailovski Pass” to study the effects of N, P and K fertilizers on apple starches. Planted autumn seedlings in the autumn of 1972, the nutritional area of 5 × 4 meters, rootstocks for the apple cultivars seedlings.
