近年来,一场油菜播种方式的革新在四川省广汉、德阳、成都等地崭露头角,目前已由小范围试验步入大面积示范。这就是油菜机械化直播,这一技术与我们通常所见油菜育苗移栽、油菜人工直播相比,最大特点就是省工省力,节本增效。以广汉市为例,1人操控1台直播机,每小时可播0.20～0.27公顷油菜田,同时,机械直播可比育苗移栽每667米2多收5.0～7.5千克菜籽。“油菜机播技术目前在广汉已经逐步成熟。今年是大面积示范。”广汉市农技站副站长廖方全认为,随着农村青壮劳力大量外
In recent years, a revolution in rapeseed sowing has emerged in Guanghan, Deyang and Chengdu in Sichuan Province. At present, it has been experimenting with large-scale demonstration experiments in a small area. This is rape mechanized live broadcast, this technology and we usually see rapeseed transplanting, rape artificial live, the most prominent feature is the labor-saving, cost-effective. Take Guanghan City as an example, 1 person controls 1 broadcast machine and can broadcast 0.20 ~ 0.27 hectare rape field per hour. At the same time, mechanical live broadcasting can receive 5.0 ~ 7.5 kg rapeseed every 667 meters 2 transplanting. “Rapeseed machine broadcast technology has been gradually matured in Guanghan this year is a large area demonstration. ” Guanghan City, deputy director of agricultural stations Liao Fangquan that with a large number of young and middle-aged rural labor
