三、选地做畦.甜瓜忌连作,应实行3～5年以上的轮作。土壤pH值以6～6.8为宜,而且应选地势高燥、背风向阳、排水良好的地块。整地时,先深翻细耙,每亩施优质农家肥5,000～6,000斤、草木炭300～500斤、过磷酸钙50斤、硫铵20斤。然后做成高10～15厘米、宽60厘米的高畦,畦间沟宽40厘米,畦长根据具体情况而定。四、移栽.甜瓜定植应在地温稳定在15℃以上、晚霜已过时为宜。定植前6～7天,每亩用0.8斤除草醚(加200斤水)喷洒畦面,然后覆盖地膜,地膜要铺平,四周用土压严。栽苗时,在畦面按50～55×58厘米的株行距打眼栽苗,栽后浇垵水,水渗后用土封垵。五、整蔓摘心.整蔓与摘心是调节植株生长与结果矛盾的主要方法。生产中多用下面两种方法:1.子蔓4～5蔓式整枝:适于子蔓坐瓜率高的品种,当主蔓4～5片叶时摘心,然后留4～5条子蔓结瓜,基部的孙蔓 Third, choose to do 畦. Melon bogey, should be implemented 3 to 5 years of rotation. Soil pH value of 6 to 6.8 is appropriate, and should be elected high potential dry, leeward sunny, well-drained plots. When the soil preparation, the first deep fine rake, high-quality farm manure per mu 5,000 to 6,000 pounds, 300 to 500 kg of grass charcoal, superphosphate 50 pounds, ammonium sulfate 20 pounds. Then made into a high 10 ~ 15 cm, 60 cm wide high 畦, 畦 between the width of 40 cm, 畦 long according to the specific circumstances. Fourth, transplanting. Melon colonization should be stable at a temperature above 15 ℃, night cream is out of date is appropriate. 6 to 7 days before planting, per mu with 0.8 kg of weeding ether (plus 200 pounds of water) spray noodles, and then cover the plastic film, the film to be paved, surrounded by soil pressure strict. Planting seedlings, in the noodles according to 50 ~ 55 × 58 cm row spacing eyeball planted seedlings planted after pouring water, water seepage after the soil seal 垵. Fifth, the whole vine topping. Whole vine and topping is the main method to adjust the contradiction between plant growth and results. The production of the following two ways: 1. Man vine 4 ~ 5 Manchurian pruning: suitable for Ziman sitting melon rate of the species, when the main vine 4 to 5 leaves topping, and then stay 4 to 5 sub-vine melon, Sun Man base
