我国土地面积很大,粮食产量南高北低,原因是北方的气温低,降雨量少,在农业生产上如何做到提温保墒,对提高农作物单产十分重要。而采用薄膜进行地面覆盖栽培恰是解决上述环境因子的重要手段。日本塑料薄膜地面覆盖概况日本是世界上进行塑料薄膜地面覆盖栽培最早的国家,栽培技术高,面积大,方式多,种类广,并创造出多种多样的塑料薄膜为不同生产方式所选用,对作物提早成熟,增加产量,改进品质,保证稳产,起到了重要作用。 The land area in our country is very big with the output of food being high in the south and low in the north. The reason is that the temperature in the north is low and rainfall is low. It is very important to raise the temperature and maintain the soil moisture in agricultural production. The use of film for ground cover cultivation is an important means to solve the above environmental factors. Japan plastic film coverage of the ground Japan is the world’s plastic film covering the earliest cultivation of the country, the cultivation of high technology, large area, many ways, wide range and create a wide range of plastic film for different production methods of choice, Early maturity of crops, increase production, improve quality and ensure stable production, played an important role.
