Embodiment Construction

[0018] The specific implementation of the present invention will be described in conjunction with the examples.

[0019] In a flue-cured tobacco test base in the rice-growing tobacco area in southern Hunan, the method application test of improving the effective utilization rate of nitrogen fertilizer in flue-cured tobacco was carried out. The variety of flue-cured tobacco is Yunyan 87. Two factors, density and fertilization method, were set in the experiment. The density is set at two levels of conventional density A1 and improved density A2, and the method of fertilization is set at two levels of conventional fertilization B1 and improved fertilization B2.

[0020] Conventional density A1: the row spacing is 120cm, the plant spacing is 55cm, and the density is 1010 plants / mu.

[0021] Improved density A2: Wide and narrow double-row "M" shaped ridge planting, such as figure 1 As shown, the wide row spacing is 120cm, the narrow row spacing is 90cm, the plant spacing is 50cm,...

Abstract

The invention belongs to the agriculture plantation technical field, and specifically relates to a southern rice cropping tobacco nitrogenous fertilizer application method; the method provides dual-line M-shape ridge mode so as to increase intensity and reduce base fertilizer nitrogen proportion, and 5 times of additional fertilizer watering can effectively improve nitrogenous fertilizer utilization efficiency, thus reducing nitrogenous fertilizer waste, saving production cost, reducing tobacco leaf nicotine content, improving tobacco leaf quality, greatly reducing environment pollution caused by nitrogenous fertilizer waste, and obviously improving tobacco output, output value and quality.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for applying nitrogen fertilizer to flue-cured tobacco for rice cultivation in southern China. Background technique [0002] In the southern tobacco area, flue-cured tobacco and rice are cropped in rotation, and rice-planted flue-cured tobacco is the main cultivation method. In the early field of rice cultivation in southern China, flue-cured tobacco grows in the low temperature and rainy season, and the effective use of nitrogen fertilizer is the key to the cultivation of flue-cured tobacco. Nitrogen is the most important element affecting the growth and quality of flue-cured tobacco. Too little nitrogen will cause malnutrition and hypoplasia of flue-cured tobacco; excessive nitrogen will affect the normal yellowing and maturity of flue-cured tobacco, high nicotine content of tobacco leaves, uncoordinated chemical components, and reduced indus...
