葡萄保护地栽培在我国是一项新的种植业,很有发展前途。现介绍如下: 一、优点1.生长期长:在加温温室内,可整年生产;不加温温室内葡萄生长期可达270天以上。2.早果、丰产:一般栽后第二年结果并进入盛果期,亩产可达到4、5千斤以上。3.可多次结果:品种对路,技术措施得当,在薄膜日光温室条件下。一年可结两茬葡萄,实现市场周年供应鲜葡萄。4.薄膜日光温室和大棚冬季不加温栽培葡萄,冬季不必下架埋土防寒,省工,不耗能源,经济效益高。二、保护地设施的类型(一) 薄膜温室在北向根据保温需要砌成加厚或空心土墙,高度1.5—3米,宽40厘米左右,每间距9米左右设一个通气窗。东西两侧墙高与钢架的拱形
Cultivation of grapes in our country is a new planting industry, great prospects for development. Are introduced as follows: First, the advantages of 1 long growth period: in the warming greenhouse, the annual production; not warming the interior of the grape growing period of up to 270 days. 2. Early fruit, high yield: the general planted the second year results and into the flourishing period, per mu can reach 4,5 kg or more. 3. Can be many times the result: variety on the road, proper technical measures, in thin film solar greenhouse conditions. Two crops a year can tie the grapes to achieve the anniversary of the market supply of fresh grapes. 4. Film greenhouse and greenhouses do not heat the cultivation of grapes in winter, winter do not have to be buried cold, labor, energy consumption, high economic efficiency. Second, the type of protected facilities (A) of the thin film greenhouse in the north according to the insulation need to build thick or hollow soil wall, a height of 1.5-3 meters, a width of 40 cm or so, each spacing of about 9 meters to set up a ventilation window. Walls on both sides of the east-west and steel arch
