水稻机插秧育秧技术关键是采用规范化育秧,它的特点是密度大、省秧田,秧龄短,秧苗成毯状。要求播种均匀,出苗整齐,根系发达,茎叶健壮,清秀无病。一、育秧前准备1.苗床土准备苗床土选择用菜园土,熟化的旱地土,或稻田土,采用机械或半机械手段进行碎土,过筛,腐熟的农家肥,加水稻专用肥。农家肥用量为用土量的20—25%,水稻专用肥的用量为用土量的2%,再拌适量的敌克松,堆捂成微酸性(Ph5—6)的营养土。每亩大田需备足营养土100千克集中堆捂。2.种子准备品种选择:选择 Rice seedling transplanting seedling technology is the key to the use of standardized nursery, which is characterized by density, the province of seedling, seedling age is short, the seedling into a carpet. Require sowing uniform, emergent neat, well-developed roots, stems and strong, handsome disease-free. First, seedling preparation 1. Seedling soil preparation seedbed soil selection with garden soil, dry arid soil, or paddy soil, mechanical or semi-mechanical means for soil, sift, decomposed manure, add fertilizer for rice. The amount of manure is 20-25% of the amount of soil used, the amount of special fertilizer for rice is 2% of the amount of soil, and then mixed with the amount of the enemy fleece, the pile covers slightly acidic (Ph5-6) nutrient soil. Each acre field needs enough nutrient soil 100 kg concentrated pile cover. 2. seed preparation variety selection: choice
