Light and simple flue-cured tobacco transplanting method

Abstract

The invention discloses a light and simple flue-cured tobacco transplanting method. Loose soil with good permeability is selected to carry out field treatment. After completion, ridges of 10-15cm areformed, row fertilization of a base fertilizer is quantitatively performed according to the number of transplanted plants, ridges of 20-25cm are formed again; when the soil moisture content of the soil reaches 60-70%, a membrane covers, the membrane is covered by soil of 2-3cm; tobacco seedlings are selected, holes are vertically drilled in the soil covering the membrane, the selected tobacco seedlings are selected into the bottoms of the holes, and the tobacco seedling substrate is covered with fire soil; after transplanting, watering, fertilizing and dosing were carried out. The method shortens the seedling raising period, reduces the work cost, improves the quality and efficiency, reduces the production period, increases the yield, and is suitable for popularization. Not only the seedling can be transplanted in time in the optimal transplanting period and the DOUGONG phenomenon is reduced, but also the influence of adverse conditions on the yield and quality of tobacco leaves is avoided. Soil covering is performed firstly and then hole drilling is then performed, the membrane around the hole is compacted, so that the membrane and tobacco stem contact fully, there is no gap between the orifice membrane and the ridge body, so as to play a good role in inhibiting weeds, and ensure the growth and development of tobacco seedlings.

Description

technical field [0001] The invention relates to the technical field of tobacco planting, in particular to a light and simple flue-cured tobacco transplanting method. Background technique [0002] In the context of global warming, my country's daily average temperature and extreme temperature are showing an upward trend. Climate change seriously affects agricultural production, advances the growth period of crops, and affects yield and quality. [0003] The study found that traditional flue-cured tobacco transplanting techniques are easily affected by low temperature stress, resulting in delayed growth of tobacco seedlings after freezing, poor agronomic traits, and reduced yield; In the best transplanting period, the tobacco seedlings are short and not strong, forming tall seedlings, and the seedling period after planting is long, etc., resulting in a low transplanting rate of strong seedlings and insufficient transplanting depth of tobacco seedlings, which restricts the furt...

Problems solved by technology

[0003] The study found that traditional flue-cured tobacco transplanting techniques are easily affected by low temperature stress, resulting in delayed growth of tobacco seedlings after freezing, poor agronomic traits, and reduced yield; Tobacco seedlings in the best transplanting period are short and not strong, forming tall seedlings, and the seedling period after planting is long, etc., resulting in a low transplanting rate of strong seedlings and insufficient transplanting depth of tobacco seedlings, which restricts the further improvement of tobacco leaf production level

[0004] The traditional flue-cured tobacco transplanting technology is not strict in the selection of soil, the control of soil moisture is not strict, and it cannot provide a relatively stable temperature, humidity and nutritional environment for the growth of tobacco seedlings in the early stage of transplanting, which can easily lead to a decline in the survival rate of tobacco seedlings; Moreover, in the process of transplanting and fertilizing, the method of first drilling and then covering soil is usually adopted, and the drilling method is simple, and the depth of drilling is not fixed, so that the transplanting depth of the tobacco seedlings is not enough, the fertilizer utilization rate is low, and the growth of the tobacco seedlings in the field is high. Inconsistency can easily lead to a sharp increase in the number of pests or no reduction in the number of pests, thereby reducing the yield and value per unit of tobacco leaves
