Embodiment Construction

[0020] Xingyi City, Qianxinan Prefecture, Guizhou Province adopts the method of the present invention to transplant spring dry tobacco seedlings, and the effect is good. The specific method is:

[0021] First, carry out soil preparation and ridge formation: without considering the soil moisture, ridges are carried out at a row spacing of 1m. The ridge body is required to be full and the ridge surface is finely divided; the bottom width of the ridge body is 70-80cm, and the height is 25-30cm.

[0022] Then, lay the drip irrigation equipment, lay the drip irrigation belt, the water delivery main pipe, the water pump, and the fertilizer applicator in sequence; There are several drippers, and the distance between two drippers and the distance between transplanting plants are both 0.6m; each drip irrigation belt controls a row of crops, and the water delivery main is connected with the water pump and the fertilizer applicator; the water delivery main uses a rubber tube with a diame...

Abstract

The invention discloses a moisture-conservation-free under-film trickle irrigation transplanting method for tobacco seedlings. The moisture-conservation-free under-film trickle irrigation transplanting method for the tobacco seedlings comprises the following steps: (1) land preparation and ridging; (2) trickle irrigation equipment spreading; (3) film mulching; (4) fertilization prior to transplantation; (5) trickle irrigation during transplantation and (6) management after transplantation. The moisture-conservation-free under-film trickle irrigation transplanting method has the advantages that the problems that the soil moisture content is low at a transplanting period of tobacco regions during spring drought, and the tobacco seedlings cannot be transplanted normally; a trickle irrigationmethod is adopted, and the water consumption is saved by over 70% compared with watering; manual water-carrying irrigation is avoided, and labor intensity and labor input are reduced; the seedling survival rate of the tobacco seedlings is improved by over 30% compared with conventional climate conditions; the fertilizer utilization rate is improved, the N fertilizer utilization rate is improved to over 40% from about conventional 30%, and the fertilizer applying amount is reduced; the yield and the quality of tobaccos are improved, the yield and the output value of the tobaccos are improved by over 20%, the content of nicotine on the middle upper portions of the tobaccos is remarkably reduced, the content of potassium ions of the tobaccos is improved, and the quality of the tobaccos is improved. The moisture-conservation-free under-film trickle irrigation transplanting method is suitable for tobacco seedling transplantation during the spring drought period.

Description

technical field [0001] The invention relates to a method for cultivating tobacco, in particular to a method for transplanting tobacco seedlings. Background technique [0002] As we all know, the seedlings cultivated by tobacco seeds need to be transplanted in the tobacco field, and the transplanting of tobacco seedlings is an important part of tobacco planting. However, if there is a spring drought and the soil moisture is low during the transplanting period in the tobacco area, the flue-cured tobacco cannot be transplanted normally. In areas with severe drought, the transplanting and survival of tobacco seedlings is indeed a difficult problem. The traditional water-carrying irrigation is laborious and labor-intensive, and it is difficult to continuously meet the needs of tobacco seedling growth. [0003] There are not many technical solutions involving tobacco seedling transplanting in Chinese patent applications, only No. 200910102961.2 "A Flue-cured Tobacco Transplantin...
