一、品种选择。日光温室杏栽培,应选择抗病性强、成形快、早果丰产、色泽艳丽的早熟优良品种。二、日光温室修建及扣棚时期首先要做好建棚前的管理,包括园地选择、苗木选择、定植、苗木定干、肥水管理及树体管理。日光温室,面积一般为667平方米左右。在建好温室后,覆盖无滴膜。夜间棚上覆盖保温被,白天揭开保温被。扣棚一般在11月下旬落叶后进行。扣棚前20天~30天树盘覆膜,预先给土壤升温,可使扣棚后地温保持较高水平,避免气温高、地温低给树体生长发育造成不利影响。另外扣棚前地上部喷5波美度的石硫合剂,以防治病虫害。扣棚后白天盖苫,晚上揭苫通风,创造0℃~7℃的低温环境,约一个月时间满足果树的需冷量,使其顺利通过自然休眠,于12月底开始升温。
First, the choice of species. Sunlight greenhouse apricot cultivation, should choose a strong disease resistance, forming fast, early fruit yield, bright color and good varieties of early maturing. Second, solar greenhouse construction and deduction period first of all to do before the construction of shed management, including the choice of garden, seedling selection, planting, seedling set dry, fertilizer and tree management. Sunlight greenhouse, the area is generally about 667 square meters. After the greenhouse is built, cover the drip-free film. The shed was covered during the night insulation was opened during the day was insulation. Buckle shed generally after deciduous leaves in November. Buckling the shed 20 days to 30 days tree tray coating, soil pre-warming, can buckle after the ground temperature to maintain a high level to avoid high temperatures, low ground temperature to adversely affect the growth and development of the tree. In addition, the top of the buckle shed spray 5 Baume degree of lime sulfur mixture to control pests and diseases. After the sheds are covered during the day and exposed at night, they are ventilated to create a low-temperature environment of 0 ° C ~ 7 ° C. The cooling capacity of fruit trees is satisfied for about one month, allowing them to pass the natural dormancy smoothly and start warming at the end of December.
