“冷凉消晚暑,清甘洗渴心”。作为夏令水果之王的西瓜,要是能在口干舌澡的伏天上市该有多好。但遗憾的是,沿用传统技术,我省不少地方的西瓜要在立秋节以后才能成熟。而采用塑料薄膜地面覆盖,不仅可以使西瓜提前十几天上市,而且可以做到又甜又沙,增产30％以上,每亩多收入100～500元。 “Cool and cool the summer, clean and wash your thirst.” As the king of summer fruit watermelon, if it can be listed in the mouth of the bloody days how good the market. But unfortunately, follow the traditional techniques, watermelon in many parts of our province to mature after the establishment of autumn festival. The use of plastic film covering the ground, not only can make watermelon listed ten days in advance, but also can be made sweet and sand, yield more than 30%, more than 100 yuan per mu income.
