Problems solved by technology

[0002] The flue-cured tobacco planting areas in northern my country are affected by the natural environment and climate, and the annual precipitation is low. The rainy season is mostly concentrated after June, and the transplanting of tobacco plants is generally in the middle and late May. Dry fields are mostly terraced fields with barren soil, high sand content and weak water storage capacity, which affect the survival rate and normal growth of tobacco plants after transplanting. The problems encountered in the transplanting and early growth of tobacco plants have not been resolved for many years. find effective solutions

Abstract

The invention belongs to the technical field of flue-cured tobacco cultivation, and particularly relates to a dry field flue-cured tobacco transplanting method. The transplanting method comprises the steps of soil preparation, hole digging, film covering, transplanting, water pouring, film uncovering and earthing up, and fertilization. According to the dry field flue-cured tobacco transplanting method provided by the invention, after hole digging and film covering, rainfall can be effectively collected in a precipitation process, and rainwater flows into holes along hole walls, and penetrates underground through reserved holes, so that the soil aquosity is increased, thus being beneficial to soil moisture conservation and transplanting; the application of bran with drugs can effectively prevent underground pests from biting roots and stems of tobacco seedlings, so that the survival rate of the tobacco seedlings is improved; and a ridging step is omitted before transplanting, and 1 field laborer can be reduced per mu of tobacco field, so that the labor cost is saved.
