营养土块和营养袋育苗,营养丰富,便于放大苗距,保护根系,定植后缓苗快,有利于早熟丰产。营养土块用的营养土,常用配方有两种:一种是腐熟草炭50%,腐熟马粪20%,大粪干10%,土20%;另一种是腐熟马粪60%,大粪干10%,土30%。育果菜秧苗可在500公斤土中加过磷酸钙0.5~1公斤。总之,有机肥应占70%以上,否则,土块板结,影响根系发育。制做营养土块的方法:一是压制法,即将配好的营养土加入适量水搅合,达到手握成团时,装在压制膜内,压制成块;二是合泥切割法,即将配好的营养土加水拌成泥状,铺在事先整平的畦内,厚10厘米,再用木板抹平,按所需苗距切成方块,土块中央扎一个小窝,准备播
Nutritional soil and nutrition bags Nursery, nutrient-rich, easy to enlarge the seedling distance, protect the root system, Huanmiao colonization fast, is conducive to early maturity and high yield. Nutrient soil with nutrition soil block, there are two commonly used formula: one is 50% matured peat, 20% matured horse manure, large manure dry 10%, soil 20%; the other is matured horse manure 60%, manure dry 10 %, Soil 30%. Fruit and vegetable seedlings can increase 500 kg of soil over calcium phosphate 0.5 to 1 kg. In short, organic fertilizer should account for more than 70%, otherwise, clods, affecting root development. Method of making nutritious clods: First, the suppression of law, about to join a good amount of nutrition soil with water mixing, to reach into a group, packed in the suppression film, pressed into pieces; second is the cohesion cut method, about to With a good nutrition soil water mix mud shape, shop in advance leveling 畦, 10 cm thick, and then smooth the board, according to the required seedling cut into squares, earth crouched a nest, ready to broadcast
