今年十月,我们作为中国温室节能技术考察团的成员,有机会到比利时进行了技术考察。比利时在世界地图上是不显眼的,国土面积只有我国的1/313,3万多平方公里,人口不足1千万。农业用地占全国总面积的46％(欧州一般为60％),农业劳动力为全国总劳力的3％,也就是说3％的人口耕种着46％的土地,人均耕种面积为4.77公顷(71.6亩)土地。农业生产中主要是以畜牧业为主,大片的草场、牧场占56％(785860公顷),农作物种植面积为58762公顷,占41％,园艺生产用地为4300公顷,占3％。园艺生产主要是以蔬菜为主,面积为2279公顷,占53％,观赏植物(花卉)占29％,面积为1247公顷,果树占18％,面积为774公顷。全国人均园艺用地4.4米~2。比利时温室分热温室和冷温室两种,热温室就是
In October this year, as a member of the China Greenhouse Energy Conservation Technology Delegation, we had the opportunity to conduct a technical study in Belgium. Belgium is inconspicuous on the world map, with a land area of only 1 / 313.3 million square kilometers and a population of less than 10 million. Agricultural land accounts for 46% of the national total (60% in Europe in general) and agricultural labor force is 3% of the total labor force in the country, which means that 3% of the population plows 46% of the land and the per capita cultivated area is 4.77 hectares (71.6 mu )land. Agricultural production is mainly dominated by livestock husbandry. Large pastures and pastures account for 56% (785,860 hectares) of cropland, 58,762 hectares of crop area, accounting for 41% of the total, and 3,300 hectares of horticultural land. Horticultural production is mainly vegetable, covering an area of 2279 hectares, accounting for 53%, ornamental plants (flowers) accounting for 29%, an area of 1247 hectares, fruit trees accounted for 18%, an area of 774 hectares. National per capita horticultural land 4.4 m ~ 2. Belgian greenhouse divided into hot and cold greenhouse two, hothouse is
