启闭式纱网薄膜育苗,是由日本引进的水稻育苗新技术。今年全省有12个科研单位和稻产区农业技术推广站采用这种新方法进行了育苗试验,普遍取得了良好效果。启闭式纱网薄膜的构造启闭式纱网薄膜的构造分为两部分,一是骨架:由2.5米长竹披子或细铁筋做架,在架条两端50厘米处弯成弓形。覆膜时每端插入土中30厘米,形成床两侧高20厘米,床中间高30～40厘米,床面宽度1.5米的苗床。二是纱网薄膜:在80厘米宽尼龙纱网的两侧,用热合机各粘合75厘米宽普通育苗用的塑料薄膜,成为中间为尼龙纱网、两侧为塑料薄膜、总宽度为2.3米的
Kai-type gauze film nursery, is introduced by Japan’s new rice seedling technology. This year, there are 12 scientific research units in the province and the Agricultural Technology Extension Station of the Rice-producing Area adopted this new method to conduct nursery experiments and generally achieved good results. The structure of the opening and closing gauze film The structure of the opening and closing gauze film is divided into two parts, one is the skeleton: made of 2.5-meter-long bamboo pens or thin iron bars, bent at 50 centimeters . Each end when the film is inserted into the soil 30 cm, forming a bed 20 cm high on both sides of the middle of the bed 30 to 40 cm high, the bed width of 1.5 m seedbed. Second, the gauze film: 80 cm wide nylon gauze on both sides, with a heat sealing machine 75 cm wide common seedling plastic film used to become the middle of nylon gauze, plastic film on both sides of the total width of 2.3 Rice
