石榴为亚热带及温带树种,世界各地广为栽培。性喜温暖和阳光充足,耐寒,耐早。对土壤要求不严,PH值4.5~8.2之间的壤土均宜,但以排水良好又较为湿润、含石灰质之地生长尤佳。石榴可用多种方法繁殖,如播种、分株、压条、嫁接、扦插等,而以扦插应用最广。南方多在“立春”与“立秋”前后扦插,北方常在“清明”前后扦插,极易成活。扦插苗一般栽培2~3年就能开花、结果。兹依石榴不用品系栽培管理方法分别介绍如下:1.果园栽培:首先应根据当地生态环境条件选择适宜的品种,在春季发芽前或秋季落叶后种植。其次应选择光照充足、无渍水之虞的场地,种植前园地要精耕细作,一般以3m×6m的株行距挖大穴,并施足基肥。通常采用自然开心型整形修剪。及时剪除枯枝、过密枝、
Pomegranate subtropical and temperate species, widely cultivated around the world. Warm and sunny nature, cold, early resistance. Lack of strict requirements on the soil, PH value of 4.5 to 8.2 between the loam should be appropriate, but with good drainage and more humid, calcareous growth is preferred. Pomegranate can be used a variety of breeding methods, such as sowing, ramets, battens, grafting, cutting, etc., and the most widely used cutting. Mostly in the south, “Spring” and “Autumn” before and after cutting, the North often in the “clear” before and after cutting, extremely easy to survive. Cutting seedlings generally cultivated 2 to 3 years to flowering, the result. Ziyi pomegranate without line cultivation and management methods are described as follows: 1. Orchard cultivation: First of all, should be based on local ecological conditions to select the appropriate species, in the spring before or after deciduous plantings. Followed by the choice of adequate lighting, no waterlogging danger of venues, before planting garden to intensive farming, usually 3m × 6m row ditch excavation large hole, and apply enough base fertilizer. Often using natural happy plastic trim. Cut dead branches in time, too close branches,
