蔬菜改良式地膜覆盖,就是将常规的覆盖法加以改良,将原来的垄背或畦面覆盖,改为沟内栽培蔬菜,淘顶覆盖地膜,造成一个“小温室”。这样能更有效地利用太阳光能,一般可提高地温2—6℃,蔬菜定植期可提前10—15天,成熟期可提前5—10天,也便于管理,增产增收。具体作法是,整地的同时要一次施足有机肥,浇足底墒水,将地整细耙平,然后根据所栽培蔬菜的行距(黄瓜、菜豆50)厘米、西瓜100厘米、甘兰 Improved vegetable mulching, that is, the conventional cover method to be improved, the original ridge or mound cover, instead of cultivation of vegetables in the trench, Amoy top cover plastic film, resulting in a “small greenhouse.” This can be more effective use of solar energy, the general increase in ground temperature 2-6 ℃, vegetable planting period of 10-15 days in advance, mature stage can be 5-10 days earlier, but also easy to manage, increase production and income. The specific approach is to cut the soil preparation at the same time enough to apply organic fertilizer, poured enough moisture at the end of the foot, the whole rake flat, and then according to the row spacing of cultivated vegetables (cucumber, bean 50) cm, watermelon 100 cm,
