二段育苗是烤烟生产中培育壮苗的一种新技术。采用此法,可以相应地延长苗床期,缩短大田生长期,确保早、中烟适时移栽;移栽后烟苗成活率高,生长整齐一致,对提高烟叶的产量和质量有明显的效果,一般可增值10～20％。具体操作过程如下:1.假植前的准备及方法在2月底～3月初,选择当年准备栽烟的地或就近的地,做成长10米、宽1.0～1.1米、高0.3米的畦床(可供1亩大田用苗)。用火土灰100～150公斤,复合肥2～3公斤,过磷酸钙5公斤,腐熟的猪牛栏粪150～200公斤,与畦面土壤充分拌和
Sec Sec is a flue-cured tobacco production in nurturing seedling a new technology. With this method, the seedling stage can be prolonged accordingly to shorten the growth period of the field to ensure that the early tobacco and the medium tobacco can be transplanted timely. After transplanting, the survival rate of the tobacco seedlings is high and the growth is neat and uniform, which has obvious effect on improving the yield and quality of the tobacco leaf. The general value-added 10 ~ 20%. The specific operation process is as follows: 1 preparation and methods of pre-implantation in the end of February ~ early March, choose the year to prepare for planting tobacco or near the ground, made of 10 meters long, 1.0-1.1 meters wide, 0.3 meters high, (Available for 1 mu field with Miao). With fire ash 100 to 150 kilograms, 2 to 3 kilograms of compound fertilizer, superphosphate 5 kg, 150-200 kilograms of maturity of pig ranch dung, and knead soil fully mixed
