培育壮苗和提高移栽质量,是烤烟优质适产的基础。80年代以来,许昌烟区的农民创造了“划方块育苗、带干土移栽”的新方法,提高了移栽质量。现介绍如下。 1、划方块育苗经过精细整畦、施足底肥、浇足底水、适时播种的苗床,在畦面上划成长、宽各7cm,深6cm 的方块。再按照方块间苗、定苗,每一方块留一棵苗。待烟苗3片真叶时一次间苗、定苗。6-7片真叶时进行锻苗。其好处有三:①苗距一致,每株烟苗的营养面积和光照条件基本相同,烟苗生长整齐,大小一致。克服了习惯育苗中烟苗稀密不匀、大小不齐的弊端。②苗床土稍干时,
Nurturing strong seedlings and improve the quality of transplanting, is the basis for high-quality tobacco production. Since the 1980s, farmers in Xuchang Tobacco Zone have created a new method of “zoned nursery with transplanting of dry soil” and improved the quality of transplanting. Now introduced as follows. 1, zoned box nursery After finishing fine, Shi enough fertilizer, pour the foot of water at the end, timely sowing seedbed, plank growth, width of 7cm, 6cm deep box. In accordance with the box between the Miao, Dingmiao, leaving each box a seedling. To be real seedlings 3 seedlings Miao, Dingmiao. 6-7 true leaf forging seedlings. The benefits of three: ① seedling spacing consistent, each plant’s nutrition area and light conditions are basically the same, tobacco seedlings grow neatly, the same size. Overcome the habit of nursery stock seedling sparse uneven, the size of the drawbacks. ② seedbed soil slightly dry,
