希腊科学家格·科利斯特拉思不久前研制出一种在干旱气候条件下的果树栽培法,先后几年在希腊和沙特阿拉伯雨量稀少的干旱地区试栽成功。具体做法是:首先在容量五十至三百升大小的塑料袋里,填满果树所需用的一切营养物质,如泥炭、灰、木炭和肥料等,把它们搅拌均匀,埋入根穴,供树根慢慢吸收,其功效可维持几年(果树所需的水分也由塑料袋 Greek scientist 格科斯特拉斯 recently developed a fruit tree cultivation method in arid climatic conditions, several years later in Greece and Saudi Arabia in arid areas of drought test planted success. This is done by first filling all the nutrients required by the fruit tree in plastic bags of 50 to 300 liters in size, such as peat, ash, charcoal and fertilizer, mixing them evenly, For root absorption slowly, its effectiveness can be maintained for several years (fruit trees also need water from plastic bags
