一、配制营养土在温室、大棚内育苗,经常需要配制营养土,用一份锯末、一份园土、一份粪肥配成的营养土效果很好。因为,①发酵后的锯末可以提高营养土的温度,有利植物插播生根。②锯末的吸水、保水、渗水性很强,有利苗木保温抗旱,提高苗木成活率。③发酵后的锯末是很好的肥料,能促进生根后的苗木的生长。④有锯末的营养土结构松暄、空隙大,利于根系呼吸和土壤内微生物活动,有利根系生长,使苗木容易根壮叶茂。⑤含有锯末的营养土,吸热快,散热慢,在北方早春育苗,尤为适用。⑥盆
First, the preparation of nutritious soil Greenhouse, nursery in the greenhouse, often need to formulate nutritious soil, with a sawdust, a garden, a manure dubbed nutrition soil works well. Because, ① after fermentation of sawdust can increase the temperature of nutrient soil, beneficial plants inserted planting rooting. ② sawdust of water, water, water seepage is strong, favorable seedling insulation and drought, improve seedling survival rate. ③ sawdust after fermentation is a good fertilizer, can promote the growth of seedlings after rooting. ④ sawdust nutrition soil structure Song Xuan, gaps, which will help the root respiration and soil microbial activity, favorable root growth, so that seedlings easily rooted strong leafy. ⑤ nutritious soil containing sawdust, fast heat absorption, heat dissipation, nursery in the early spring in the north, especially applicable. ⑥ basin
