目前大棚栽培葡萄往往第1年和第2年没有产量或产量很低,为探讨提高大棚葡萄前期经济效益的有效途径,笔者于1993-1999年在山东省潍坊市卧龙镇大棚葡萄基地就京秀葡萄保护地大苗当年栽培,第二年高产进行了种植试验。1.棚体构造 大棚为琴弦式冬暖式大棚,棚宽10m,长60m,总面积600m2。东西北三面均为土体墙,墙底脚宽1m,顶宽 0.9m,后墙高 2m,山肩高3.2m,山墙南侧高1m。在棚内按设计高度和南北间距,每 3.6m埋入1根水泥预制立柱,然后将毛竹按南北方向固定在立柱上,最后用8号铁丝顺东西方向每0.3m拉一道铁丝,形成上下相接,左右相连的固定骨架。冬季来临前,用无滴膜封顶,膜上用小竹条压住,并准备宽1.2m、长13m的稻草苫子60条。2.培育壮苗 培育健壮无病的苗木是大棚葡萄丰产的基础。壮苗枝蔓的要求是节间短、枝条充实、 Currently greenhouse cultivation of grapes are often the first year and the second year without yield or yield is very low, in order to explore an effective way to improve the pre-economic benefits of greenhouse grape, the author in 1993-1999 in Wolong Town, Weifang City, Shandong Province greenhouse grape base on the Beijing show Cultivation of grapes in the conservation of the year, the second year of high-yield planting test. 1. Shed structure Greenhouse for the string type winter-warm shed, shed width 10m, length 60m, the total area of ​​600m2. The three sides of East and West are soil walls. The foot of the wall is 1m wide with a top width of 0.9m and a back wall of 2m. The height of the mountain shoulder is 3.2m and the height of the south wall of the gable is 1m. In the shed according to the design height and north-south spacing, every 3.6m buried in a cement prefabricated columns, and then the bamboo in the north-south direction is fixed to the column, and finally with the 8th iron wire along the east-west direction 0.3m pull a wire to form the upper and lower phase Then, connected to the fixed skeleton. Before the onset of winter, use a drip-free membrane to seal the top of the membrane. Use small bamboo straps to hold it in place and prepare 60 straws of rice straw that are 1.2m wide and 13m long. 2. Nurturing seedlings Nurturing seedlings is robust and disease-free greenhouse seedlings are the basis for high yield. Strong seedlings dendrite requirements are internodes short, full of branches,
