在海城市农业现代化综合科学实验基地建设中,我们针对海城市东部低山丘陵区796万株果树中,新栽幼树多、结果晚等问题,与市乡有关部门共同进行了苹果、梨、山楂幼树早期丰产技术的研究和推广。实践证明,采用幼树早期丰产技术,可使幼树提早两、三年结果,并增产20—30％。一、深耕改土.幼树栽植坑要求直径1—1.5米,深80—100厘米,在栽树时可根据土质情况,采取沙掺泥,粘掺沙的方法改良土壤,同时每株施入土粪25—50公斤,栽后
In the construction of comprehensive experimental base for agriculture modernization in Haicheng City, we conducted a survey of 7,960,000 fruit trees in the hilly region of the eastern part of Haicheng City, newly planted more saplings and late results. Together with the municipal authorities, Research and Popularization of Hawthorn Saplings Early High Yield Technology. Practice has proved that the early sapling technology with young trees, young trees can make two to three years ahead of schedule, and an increase of 20-30%. First, deep plowing and soil improvement Saplings planting pit diameter of 1-1.5 meters, 80-100 cm deep, according to the soil conditions in planting trees, to take sand mixed with mud, sticky sand method to improve the soil, while each plant applied Soil manure 25-50 kg, after planting
