Problems solved by technology

However, studies have shown that compared with the application of urea on tobacco, compared with the application of ammonium nitric acid and ammonium sulfate, the root system of tobacco is underdeveloped, the leaves are thinner, the color of tobacco leaves after roasting is light, and the taste is flat.
Long-term application will cause soil compaction, increased soil salinization, slow plant growth, increased pests and diseases, and reduced yield, as well as non-point source pollution.
In the past, the ordinary tobacco-specific fertilizers have been difficult to meet people's quality requirements for tobacco leaves, so there is an urgent need for suitable compound fertilizers to cultivate high-quality Honghua Dajinyuan flue-cured tobacco

Embodiment 1

[0019] Embodiment 1 Preparation of biologically active organic substances

[0020] 1 ton of peat is leached with 2 tons of sodium pyrophosphate solution (concentration of 15% by weight) for 24 hours, and the aforementioned solution is filtered through a 40-mesh screen, and the obtained filtrate is heated to 100°C, and the biologically active organic Substance 410kg.

Embodiment 2

[0021] Example 2 Preparation of Compound Fertilizer for Safflower Dajinyuan Flue-cured Tobacco

[0022] Preparation of trace elements: disodium tetraborate decahydrate (Na 2 B 4 o 7 10H 2 O), langbeinite anhydrous (K 2 SO 4 2MgSO 4 ), zinc sulfate heptahydrate (ZnSO 4 ·7H 2 O) and potassium chloride are uniformly mixed in a weight ratio of B:Mg:Zn:KCl=2.0:3.8:2.0:1.0.

[0023] Add 485.1Kg of potassium sulfate, 11.55Kg of potassium nitrate, 123.2Kg of monoammonium phosphate, 200.2Kg of ammonium nitrate, 46.2Kg of bentonite, 30Kg of biologically active organic matter (obtained in Example 1), 18Kg of trace elements, and 25Kg of water into the batching tank , stir well. React at 60-70°C, the surface tension of the liquid in the slurry tank increases, and many bubbles are generated in the slurry tank, and rapeseed oil (500ml per ton of slurry) is added to the slurry tank to destroy the surface tension. It is pumped into the spray tank through the batching pump, and then i...

Embodiment 3

[0024] Example 3 Effect Test of Compound Fertilizer for Safflower Dajinyuan Flue-cured Tobacco

[0025] The compound fertilizer for Honghua Dajinyuan flue-cured tobacco prepared in Example 2 was applied to the planting soil of Honghua Dajinyuan flue-cured tobacco at 40 kg per mu. The harvested tobacco leaves were observed by the naked eye to be healthy and healthy. The upper tobacco leaves were well-opened, moderately thick, well-developed, wide-shaped, vigorous in the field, and had obvious layering and yellowing at maturity.

[0026] A conventional tobacco-specific fertilizer with 48% of total nutrients was applied to the soil for planting Honghua Dajinyuan flue-cured tobacco at 50 kg per mu as a control sample.

[0027] The Honghua Dajinyuan flue-cured tobacco planted with the compound fertilizer prepared in Example 2 is easy to bake, and the orange-yellow tobacco leaves increase significantly. After roasting, the color of the tobacco leaves is bright, the amount of aroma ...

Abstract

The utility model provides a compound fertilizer used for Honghuadajinyuan cured tobacco, and a preparation method thereof, belonging to the technological field of compound fertilizers. The invention aims at solving the technological problem of providing a compound fertilizer used for Honghuadajinyuan cured tobacco. Tobacco plants can grow well, leaves are wide, tobacco leaves are easy to be baked and the amount of aroma is increased by using the fertilizer. The fertilizer is mainly prepared by 5 portions of bioactive organic substances, 77 portions of inorganic fertilizers and 18 portions of trace elements; total nutrient contents are N accounting for 17.3% to 19.0%, P2O5 accounting for 19.6% to 21.1% and K2O accounting for 60.5% to 61.2%. Tobacco plants can grow well and the growth vigour is prosperous after the compound fertilizer is applied; the output is increased by 9.78%, the tobacco leaves of the rate of the high grade and the middle are increased by 4.9% and the output value is increased by 12.9%; the tobacco leaves are brilliant and oleosus in luster, chemical constituents tend to be coordinate, and sugar-nicotine ratio, nitrogen-nicotine ratio and total nicotine all comply with the quality evaluation standard of raw tobacco chemical constituents.

Description

technical field [0001] The invention relates to a compound fertilizer for flue-cured tobacco, belonging to the technical field of compound fertilizers. Background technique [0002] Flue-cured tobacco of the Honghua Dajinyuan variety was widely planted in the national smoking areas in the 1980s. At that time, it was a common fertilizer for tobacco, and the formula was: N:P 2 o 5 :K 2 O=12%: 12%: 24%, total nutrient 48%, the nitrogen source of this type of fertilizer is mainly urea, i.e. biuret form (C 2 h 5 N 3 o 2 ). There are many shortcomings in the safflower Dajinyuan variety. During the planting process, it is susceptible to black shank, viral disease, root-knot nematode and red spot disease. At the same time, it is sensitive to nitrogen in fertilizers. Low, difficult to bake. Since then, with the introduction of new varieties from the United States and the popularization and promotion of the Yunyan series varieties bred by the Yunnan Tobacco Branch, the plantin...
