1、蒜田套种西瓜栽培技术一、育苗时间:4月上旬育苗二、育苗:1、无土育苗2、营养钵育苗:A浸种:把砧木种放到60℃的热水中浸泡,并不断搅拌至30℃,浸种48小时,捞出后冲洗干净,然后放到30~32℃条件下催芽。B播种:当砧木芽长至0.5厘米时播种,播种时种子要平放,芽端向下,上面覆盖1~15厘米的营养土,上盖一层地膜。C当砧木出齐后,即可泡西瓜把西瓜种放到55℃的温水中,不断搅拌降温至30℃浸种6~8小时,捞出后搓掉种子表面的粘着物质,用清水冲洗干净,用毛巾擦干,然后放到33℃的恒温下催芽,等出芽后播种。D嫁接:当接穗露出新叶时,即可嫁接。三、整地施肥
2、:每亩地用腐熟鸡粪3方,复合肥200斤做基肥,大蒜畦宽90厘米,畦背宽20厘米和40厘米间隔安排。在40厘米宽的畦背上覆膜种植无籽西瓜。四、定植:当瓜苗长至二叶一心~三叶一心时,即可选择晴天定植,株距40~45厘米,每亩地定植西瓜650~700株,定植后加盖小拱棚,盖草苫子。五、定植后的管理:1、整枝:三蔓整枝,一条结果蔓,二条营养蔓,其余侧枝全部打掉;2、压蔓:露地西瓜为防止风刮,必须压蔓,可用枝条做成"^"型,把瓜蔓固定好;3、授粉:当主蔓出现第二或第三雌花时授粉,授粉时间在上午7:00~9:00,用雄花给雌花授粉;4、水肥管理:当瓜蔓长至1米
3、左右时,浇一次水,随水冲施尿素10公斤亩,当幼果长至鸡蛋大小时浇一次水,冲肥尿素30斤,硫酸钾40斤,7~10天后再冲一次肥水,冲施尿素20斤,硫酸钾30斤;5、采收:西瓜从授粉座果到成熟需30~35天,提前采摘,皮厚糖度低,影响效益,过晚影响产量。六、病虫害防治:1、苗期病害主要有:猝倒病、炭疽病、蔓枯病;2、防治:猝倒病可用苗菌敌防治炭疽病可用炭疽福美、施保功防治蔓枯病主要用甲托与代森锰锌混合成糊状抹杆。developmentdirection,preventionmedicalpatientdisputes,badevent,hospital
