西瓜地膜覆盖栽培是一项有效的增产增收措施。但必须注意: 1.要有适合的土壤墒情。粘土墒度“宁干勿湿”,土壤含水量14～16％,砂土墒度“宁湿勿干”,含水量不低于18％。 2.要掌握温度。膜内5～10厘米地温稳定在16℃以上,是播种适期,提前或推后不利于保苗和早熟。 3.严格掌握铺膜和播种质量。要求土壤细碎,地面平整干净,铺膜平展,压膜严实,破口适时封严;播行笔直,株距均匀,播量准确,每塘3～4粒,种深1.5～2厘米。 Watermelon mulching cultivation is an effective measure to increase yield and income. But must pay attention to: 1 have suitable soil moisture. Clay soil moisture “rather dry than wet,” the soil moisture content of 14 to 16%, soil moisture “rather wet do not dry,” water content of not less than 18%. 2. To master the temperature. 5 ~ 10 cm in the film temperature stable at above 16 ℃, is the sowing period, early or delayed is not conducive to seedlings and precocious. 3. Strict control of filming and sowing quality. Requirements of soil crushing, the ground is clean and smooth, spreading membrane flat, laminated tight, timely break seal; Sowing straight, spacing evenly, sowing accuracy, 3 to 4 per pond, deep 1.5 to 2 cm.
