一、前言云南省烤烟研究所1964年开始进行培育烤烟壮苗技术的研究,试验得出:间苗后田间通风透光,单株营养面积适宜,能够培育出壮苗的定苗距离以2寸见方为好。接着又作了间苗、锻苗与烤烟产量品质关系的研究,结果指出:每隔1寸见方留苗1株锻苗的,产量比不间苗锻苗的增加15.67%,烟叶平均单价提高13.95%;每隔2寸见方留苗1株锻苗的,产量比1寸见方留苗1株锻苗的增长17.25%,平均单价上升6.98%。验证了距离2寸定苗、锻苗的壮苗有明显的增产增质效应。
I. Introduction Yunnan Institute of Flue-cured Tobacco began in 1964 to cultivate flue-cured tobacco strong seedling technology research, the experiment concluded: after the seedling field ventilation and light, the appropriate nutrient area per plant, can grow strong seedling seedlings to 2-inch square it is good. The results showed that for every inch of Fanglianmiao 1 forged seedling, the yield increased 15.67% and the average unit price of tobacco increased by 13.95%. For every 2 inch square Fangliu 1 forged seedlings, the yield is 1 square inch Fangliu 1 forged seedlings increased 17.25%, the average unit price increased 6.98%. Verify that the seedlings from 2 inches Dingmiao, forging seedlings have obvious effects of increasing production and increasing quality.
