我场属黄河故道地区,土壤系粉沙土,土层比较深厚、肥沃。1958年冬定植苹果250亩,株行距6×8米,每亩13.8株,其中37%是倭锦品种,于1959年冬和1960年春,每株施猪圈肥60-70斤,以后未再施肥。直至1962年倭锦树体生长仍很旺,当年新梢生长量一般在85-90厘米,甚至有长达100厘米以上的,而结果枝形成极少。虽在1961年开始有部分植株开花,但座果率仅在2%,未能达到适龄结果,早期丰产。倭锦在我区生长过旺,座果率低的现象极为普遍。一、倭锦旺树座果率低的主要原因本园在1962年前由于整形修剪技术不当,对当年生枝条的短截过多、过重,因而刺激了营养生长,形成大量的外围发育枝,造成树冠郁闭,
My field is the old course of the Yellow River, the soil Department of pink sand, soil more deep, fertile. 1958 Winter planting 250 acres of apples, spacing of 6 × 8 meters, 13.8 strains per acre, of which 37% is the Japanese Kam varieties, in the winter of 1959 and the spring of 1960, each pig styler 60-70 pounds, after no fertilization . Until 1962, Japanese Kam tree body growth is still very busy, when the growth of shoots generally 85-90 cm, and even up to 100 cm long, and the results of the formation of very few branches. Although some plants began to bloom in 1961, the fruit set rate was only 2%, which failed to reach the appropriate age for early harvest. Japanese brocade in my area over-growth, low fruitsetting rate is extremely common. One, the main reason for the low fruit rate of Japanese Jinwang tree The garden in 1962 due to improper plastic surgery pruning, the current branch of the short cut too much, too heavy, thus stimulating the vegetative growth, the formation of a large number of peripheral development of branches , Resulting in crown closed,
