五、存在的问题及进一步提高优质烟品质的意见(一)改进田间栽培技术加深耕作层,实行高培土。烟田耕层浅,做垄培土不高,是该区普遍存在的问题,应引起重视。据抽样考察,一般耕深13厘米左右,培土垄高23厘米左右,耕层浅,培土不高,土壤通透性不良,直接影响根系的发育和地上部的生长。建议逐渐推广初冬深耕翻土,经过一段时间的风化,耕深25—33厘米,加深耕作层。栽烟起垄高度25—33厘米,以后结合施肥逐次
Fifth, the existing problems and further improve the quality of high-quality tobacco views (A) improve field cultivation techniques to deepen farming layer, the implementation of high soil. Tobacco field shallow tillage, ridge farming soil is not high, the area is a common problem that deserves attention. According to the sample survey, the general tillage depth is about 13 centimeters, and the soil cultivation ridge is about 23 centimeters high. The tillage is shallow, the soil is not high and the soil permeability is not good, which directly affects the root development and shoot growth. Proposal gradually promote the early winter deep tillage, after a period of weathering, deep plowing 25-33 cm, deepen the tillage. Planting tobacco ridge height of 25-33 cm, after the combination of fertilization followed
