1.此时天气渐暖,土壤日化夜冻,日平均气温在4℃左右。2.整地作床。选择距本田较近、避风向阳、土质肥沃、水源方便的旱田地、菜地或宅旁地做育苗地。趁白天土壤化冻,化一层铲一层做好苗床。尽量做到旱整地、旱作床。一般长15米、宽1.5米的苗床,足够1亩本田插秧需要。为防止出现意外,可多育10%左右秧苗。目前比较先进的育苗方法是双幅塑料薄膜覆盖启闭式高架育苗。床长15~20米,宽2.0~2.2米,床架中间高1米,两侧高60厘米,用两块塑料布(一块整幅、一块半幅)覆盖,中问重叠。这种苗床内部空间大、温差小、易管理、成苗率高,秧苗质量好,可以降低秧、本田比例,降低生产成本。
1. At this point the weather getting warmer, the soil at night freeze, the average daily temperature around 4 ℃. 2. Site preparation for bed. Choose to be closer to Honda, sheltered from the sun, fertile soil, convenient source of dry land, vegetable or residential area to do nursery. During the day soil thawing, a layer of shovel a good seedbed. As far as possible to dry arid, dry bed. General 15 meters long, 1.5 meters wide seedbed, enough 1 mu Honda transplanting needs. In order to prevent accidents, more than 10% can grow more seedlings. At present, the more advanced seedling raising method is the double-width plastic film covered hoisting and raising height seedling. Bed length of 15 to 20 meters, width 2.0 to 2.2 meters, the middle of the bed frame 1 meter high, 60 cm high on both sides, with two plastic sheets (a full, a half-width) cover, asked overlap. This seedbed interior space, small temperature difference, easy to manage, high seedling rate, good quality seedlings, can reduce the seedling, Honda ratio, reduce production costs.
