培育营养袋苗具有省工、省种、苗全、苗齐,苗壮等优点。采用营养袋苗造林,由于全根全苗,造林成活率均可保持90％以上:由于带土移植,苗木可继续生长,没有缓苗期,经造后一年检查,无论苗高或直径生长均超过裸根苗的一倍以上,可提早一年郁闭,是实现速生丰产的关键性措施之一。营养袋育苗分为直播和移植两种,其中以移植苗效果最好,主要技术关键是: 1.塑料营养袋的规格:高12厘米,周长20厘米,厚2—3丝为宜。装土后直径6.5厘米,可装营养土
Nursery bag cultivation with labor, provincial species, Miao Quan, Miao Qi, Miao Zhuang and other advantages. The use of bags of seedlings afforestation, due to the whole root seedlings, afforestation survival rate can be maintained above 90%: As with the soil transplant, seedlings can continue to grow, there is no hibernation stage, after a year of inspection, regardless of height or diameter growth Are more than twice the bare root seedlings can be closed one year earlier, is one of the key measures to achieve fast growing and high yield. Nutritional bags Nursery is divided into two kinds of live and transplanted, of which the best effect of transplanting, the main technical points are: 1. Plastic nutrition bag size: 12 cm high, 20 cm long, thick 2-3 silk appropriate. Diameter 6.5 cm after loading soil, can be loaded nutrition soil
