西瓜地膜覆盖栽培形式有:地面覆盖、小拱棚覆盖和双膜覆盖。 1、地面覆盖用塑料薄膜沿瓜垄紧贴地面覆盖,幼苗在膜下生长速度比在膜外快一倍左右。我省春天风大,若覆膜质量差,膜边压不紧,膜面皱褶松驰,大风一刮,地膜就会被撕裂,甚至随风飘走。此外,覆膜质量不好,还会影响土湿及保水、保肥效果,甚至出现草荒。
Watermelon mulching cultivation forms are: ground cover, small arch cover and double-film coverage. 1, the ground cover plastic film along the melon ridge close to the ground cover, seedlings grow faster than in the film about twice faster. Spring wind in our province, if the coating quality is poor, the membrane pressure is not tight, the membrane surface wrinkles relaxation, wind grizzled, the film will be torn, and even the wind drift away. In addition, the coating quality is not good, but also affect the soil moisture and water retention, fertilizer effect, or even grassland shortage.
