玉米地膜覆盖栽培是一项综合高产栽培技术.它能为作物生长发育创造良好的生态环境,具有增产幅度大、经济效益高、适应范围广、增产效果稳定等特点。为此,发展地膜覆盖栽培技术具有广阔的前景。 1 地膜覆盖与土温和水分地膜覆盖栽培是人为控制温度、水分、光能、养分技术等综合运用的一项系统工程。覆膜的玉米能蓄热增温,薄膜又具有透光、隔水、隔热和不透性的功能,使膜与面之间形成一个狭小的温室,产
Mulching mulching is a comprehensive high-yielding cultivation technique, which can create a good ecological environment for crop growth and development, has the characteristics of large yield increase, high economic benefit, wide adaptability and stable yield. Therefore, the development of plastic film mulching cultivation has broad prospects. A plastic film mulching and soil moisture and moisture Mulch is a man-made control of temperature, moisture, light energy, nutrients and other integrated use of a systematic project. Film coated corn can heat up the temperature, the film has a transparent, water, heat and impermeability of the function, the film and the surface to form a small greenhouse, production
