夏西瓜一般在麦收后种植,7～8月份上市。夏西瓜生长期正值天气湿热季节,对技术要求较严。 一、做到“两选”。一选地块,一般应选择排灌方便,不易积水,土质深松,有水浇条件的地块;二选优种,选丰产早熟杂交种,如郑杂5号、丰收3号、法国红花等品种。 二、适时早播。直播,应采取催芽措施,麦收后立即整地做畦,亩密度500～600株。点种,每穴2～3粒,盖3厘米左右厚的土,种后盖地膜,并注意打眼放苗出膜,防止高温烫苗。 三、合理施肥。基肥以有机肥为主,尤其要多施饼肥,适当掺入少量速效肥,一般亩施粗肥5000公斤。移栽缓苗后,应加强肥水管理;座果后,追一次复合肥,如磷酸二铵、氮磷钾1号等,第一批果采收
Summer melon is generally planted in wheat after harvest, 7 to August market. Summer watermelon growing season when the hot and humid season, the more stringent technical requirements. First, to achieve “two elections.” A selection of plots, the general should choose to facilitate irrigation and drainage, easy to accumulate water, deep soil conditions, with water conditions of the plots; second choice of elite, selection of high yielding hybrids, such as Zhengza 5, harvest 3, France Red Flowers and other varieties. Second, timely early broadcast. Live broadcast, should take the sprouting measures, immediately after the wheat harvest soil preparation 畦, mu density of 500 to 600 strains. Point species, 2 to 3 holes per hole, cover about 3 cm thick soil, cover the film after the cover, and pay attention to eye-opening Fangmiao film, to prevent high-temperature hot seedlings. Third, rational fertilization. Basic fertilizer to organic fertilizer, in particular, to apply more cake fertilizer, appropriate incorporation of a small amount of quick-acting fertilizer, general Mushi Shi 5000 kg. After transplanting Huanmiao, fertilizer and water management should be strengthened; after the fruit, chasing a compound fertilizer, such as DAP, NPK No. 1, the first batch of fruit harvest
