Problems solved by technology

[0007] The purpose of the present invention is to aim at the excessive application of nitrogen fertilizer in the current traditional rice stubble flue-cured tobacco thin-value high-fertilization cultivation mode, and the effective utilization rate of nitrogen fertilizer is low, which leads to the decline of tobacco leaf quality (inconsistent chemical composition of tobacco leaf, poor physical properties), increased production cost, and pollution. Environmental problems arise, and it is necessary to provide an environmentally friendly rice stubble flue-cured tobacco that can not only ensure high-quality and suitable production of flue-cured tobacco, but also significantly improve the utilization efficiency of flue-cured tobacco on nitrogen fertilizers. cultivation method

Embodiment 1

[0041] In 2015, a comparative test of different planting patterns of rice stubble flue-cured tobacco was carried out at a test base in a certain tobacco area in southern Hunan. The variety of flue-cured tobacco was Yunyan 87.

[0042]Traditional planting mode A: ①Planting density 927 plants / mu, row spacing 120cm, plant spacing 60cm; ②Single-row ridge planting, ridge depth 20cm; ③Pure nitrogen application 12kg / mu, basal nitrogen accounted for 71% of the total nitrogen application, dedicated to tobacco 100kg of base fertilizer and 10kg of cake fertilizer are spread in the middle of the row to form a ridge, and the first topdressing is applied on 5 days after transplanting, and 3kg of special seedling fertilizer for tobacco is applied with water, and the second topdressing is applied on 20 days after transplanting. Apply 2kg of seedling fertilizer and 25kg of topdressing fertilizer specially for tobacco on both sides of the tobacco plant;

Embodiment 2

[0062] In 2014, a comparative test of different planting patterns of rice stubble flue-cured tobacco was carried out at a test base in a certain tobacco area in central Hunan. The flue-cured tobacco variety was K326.

[0063] Traditional planting mode A: ①planting density 1010 plants / mu, row spacing 120cm, plant spacing 55cm; ②single-row ridge planting, furrow depth 25cm; ③pure nitrogen application 11.9kg / mu, basal nitrogen accounted for 64.71% of total nitrogen application, tobacco 90kg of special base fertilizer and 10kg of cake fertilizer are spread in the middle of the row to form a ridge, and the first topdressing is applied 7 days after transplanting, and 3kg of special seedling fertilizer for tobacco is mixed with water, and the second topdressing is applied on 21 days after transplanting. Apply 3kg of special seedling fertilizer and 3kg of tobacco special top dressing on both sides of the tobacco plant; ④ 45 days after transplanting, water with 10kg / mu of potassium sulf...

Abstract

The invention provides a cultivation method of rice stubble flue-cured tobacco. By improving the planting density of the rice stubble flue-cured tobacco and reducing the nitrogen fertilizer consumption, especially, increasing the topdressing fertilizer nitrogen ratio, reducing the nitrogen fertilizer consumption at the early stage, increasing the topdressing fertilizer application frequency, applying topdressing fertilizer nitrogen and water and other measures and other group regulation and control cultivation techniques, not only the high quality and reasonable yield of the rice stubble flue-cured tobacco can be guaranteed, but also the nitrogen fertilizer utilization efficiency of the flue-cured tobacco can be significantly improved, and a green, nitrogen-reducing, high-yield synergy effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a cultivation method of rice stubble flue-cured tobacco. Background technique [0002] Nitrogen is the most important element affecting the growth of flue-cured tobacco and the quality of tobacco leaves. Flue-cured tobacco absorbs too little nitrogen and is malnourished, which will lead to low yield of flue-cured tobacco and decline in tobacco leaf quality; excessive nitrogen absorption by flue-cured tobacco will make it difficult for tobacco leaves to yellow and mature normally, and the content of nicotine in tobacco leaves is high. Incongruous composition and poor industrial usability. [0003] Flue-cured tobacco with rice stubble (planting rice after harvesting flue-cured tobacco within one year) is the main way of flue-cured tobacco cultivation in southern tobacco-growing areas. In the early stage of rice stubble flue-cured tobacco cultivation in t...
