近几年,果树生产发展迅猛,面积与产量逐年上升,但单位面积产量一直在200—400公斤之间徘徊;同时生产中还存在着果品质量低劣等问题。经过调查分析发现,栽培技术的落后是阻碍果树生产水平提高的一个主要限制因子。为此,就栽培技术环节中的一些主要问题加以商榷。一、改善肥水条件,复壮树势。在低产果园改造过程中,加强肥水管理是首要工作,除秋冬季节施足基肥外,还应根据果树各个时期的营养状态,在适当的时间追施果树所需的速效肥料。结果期果树生长季节一般每株施化肥1—2公斤或人粪尿60公斤。并结合喷药每年叶面喷肥3—5次,有条件的果园可间作绿肥扩大肥源。果园施肥还应注意施肥不平衡 In recent years, fruit tree production has witnessed rapid development and the area and output have been increasing year by year. However, the output per unit area has been hovering between 200 and 400 kg. At the same time, there are still problems in the production such as poor fruit quality. After investigation and analysis, it is found that the backward cultivation technique is a major limiting factor that hinders the improvement of fruit tree production level. For this reason, some major problems in the cultivation technology are discussed. First, to improve fertilizer and water conditions, rejuvenation trees. In the low-yield orchard renovation process, to strengthen fertilizer and water management is the most important work, in addition to the Shizujifei autumn and winter seasons, but also should be based on nutritional status of the various periods of fruit trees at the appropriate time chasing fruit trees required for quick-fertilizers. Fruit tree growth season results generally 1-2 kg of fertilizer per plant or human waste 60 kg. In combination with spraying the foliar fertilizer 3-5 times a year, conditional orchards can serve as green manure to expand fertilizer source. Orchard fertilization should also pay attention to uneven fertilization
