Embodiment 1

[0020] The method for moderately prolonging the vegetative growth period of flue-cured tobacco in the present invention includes processes such as germination-promoting coated seeds of flue-cured tobacco, regermination treatment, sowing, seedbed growth, transplanting, field growth, and field nutrient regulation, wherein the seedbed growth includes four stages: 1) Emergence stage, from sowing to emergence; 2) Cross stage, from emergence to the birth of the third true leaf; 3) Rooting stage, from the third true leaf to the birth of the seventh true leaf; 4) Seedling stage, from the seventh true leaf to the birth of the seedling planting; field growth includes four periods: 1) the seedling stage, from transplanting to survival, the process takes 7 to 10 days; 2) the rooting stage, from seedlings to clusters; 3) long-term prosperity, from clusters to budding ;4) Maturity stage, from budding to maturity; the first nutritional regulation is performed about 10 days after transplanting...

Abstract

The invention discloses a method for improving the tobacco quality by the modest extension of a vegetative growth period of flue-cured tobaccos. The method comprises the processes of primed pelleted seeds of flue-cured tobaccos, seeding, seedbed growing, transplanting, growth in field and the like, wherein the seeds germinate again before sowing the primed pelleted seeds of flue-cured tobaccos; the nutritional regulation is performed for the first time 10 days after transplanting in the field, the dosage is 5 kg per acre; the nutritional regulation is performed for the second time 35 days after transplanting in the field, the dosage is 10 kg per acre. The method is convenient for the flue-cured tobaccos to fully absorb nutrients in the vegetative growth period, is more conducive to accumulating dry matters of leaves, improving the chemical components, appearance quality and sensory evaluation of the flue-cured tobaccos and improving the quality of tobaccos by delaying the flower bud differentiation time of the flue-cured tobaccos, extending the vegetative growth period of the flue-cured tobaccos and shortening a reproductive growth period of the flue-cured tobaccos.

Description

technical field [0001] The invention relates to a method for improving the quality of tobacco leaves by moderately prolonging the vegetative growth period of flue-cured tobacco, and belongs to the technical fields of flue-cured tobacco cultivation technology and tobacco leaf quality regulation. Background technique [0002] Flue-cured tobacco is a special economic crop mainly harvesting vegetative organ leaves and high economic benefits. In the process of flue-cured tobacco production, it is necessary to promote the maximum growth and absorption of vegetative organs and leaves, and inhibit or block the growth and development of reproductive organs, flowers and seeds, so as to improve the quality of tobacco leaves and meet the needs of cigarette companies for the quality of raw tobacco leaves. In terms of improving the quality of tobacco leaves, technical measures such as improving fertilization formula, increasing application of trace element foliar fertilizer, increasing ap...
