Description
Technical Field
The invention belongs to the technical field of flue-cured tobacco cultivation, and particularly relates to a fertilizer for improving karst tobacco region soil and improving the yield and quality of flue-cured tobacco and a using method thereof.
Background
Tobacco leaves are one of the most important economic crops in China, the cultivation area and the yield of the tobacco leaves are the first place around the world, and the tax profits generated by the tobacco industry are also one of the main sources of the financial income in China. The Wenshan is in the south of the Yuangui plateau and has good natural environment conditions, so that a cigarette brand with outstanding style characteristics of good aroma quality and sufficient aroma in the Wenshan area is formed, and the West mountain is one of main production areas of the tobacco leaves in the southwest plateau-fresh and sweet aroma type style. The smoke zone is located in a typical karst landform zone, and the earthy products are mostly derived from thin layers of shale between carbonate rock acid insolubles (generally composed of silicate products) and carbonate rocks. Due to the high solubility of the carbonate, the overground and underground of the karst region are of a double-layer hydrogeological structure, the leakage of the water level of the earth surface is prominent, and the utilization rate of natural resources is obviously reduced; the carbonate rock soil forming speed is slow, so that the soil quantity is small, the ground cover block is discontinuous, the pH value of the soil is alkaline, and the land productivity in the karst region is low. The natural environment in the karst mountainous area is fragile, and improper use of human beings on soil causes a large amount of soil loss, the soil is thinned, the calcium-magnesium ratio of the soil is unbalanced, and the lack of effective boron and water-soluble chlorine in the soil reaches moderate to severe degree.
The potassium, calcium, magnesium, boron and chlorine elements participate in various physiological metabolisms of the flue-cured tobacco and form close relations with the quality of the tobacco leaves, the supplied medium is mainly soil, and the content of the available state in the soil directly influences the absorption and accumulation of the tobacco on other nutrients. Potassium appears in the form of cations, almost participates in all physiological and biochemical processes in the tobacco plant, can protect the cell turgor and reduce the heat transpiration of the tobacco plant, thereby improving the cell enzyme activity, the photosynthetic function, the generation of substances and the absorption of nitrogen and improving the stress resistance of the tobacco plant. Magnesium is also an important component of chlorophyll, plays a great role in photosynthesis, is closely related to the conversion and decomposition of carbohydrates and nitrogen metabolism thereof, and participates in the formation of proteins such as DNA, RNA and the like. The proper amount of magnesium fertilizer is beneficial to the accumulation of dry matters of root systems and improves the internal quality of tobacco leaves. The growth and development of tobacco plants are affected by the lack of magnesium, the tobacco leaves are dark green and aged too early and can not mature normally, and the prepared tobacco leaves are dark gray, dull, elastic and poor in oil content. Calcium is the main pectic acid component of the intercellular layer of the tobacco cell wall, is used as a bridge for connecting phosphoric acid and protein hydroxyl in phospholipid, and has the functions of maintaining the membrane structure, maintaining the integrity of cells, maintaining the pore diameter and permeability of the cell wall and avoiding the exosmosis of potassium in the cells.
Boron is a necessary trace component of tobacco plants, directly promotes the metabolism and transfer of carbohydrates in the tobacco plants, simultaneously influences the formation of protein and alkaloid, and is directly related to the formation of tobacco yield and quality. The boron which is absorbed by the plants mainly is water-soluble boron, namely effective boron, and the boron is sprayed on the leaf surfaces, so that the boron is easily absorbed by the plants and takes effect quickly. The insufficiency or excess of boron can cause tobacco physiological dysfunction, growth and development badness and disease resistance reduction. The balance of chemical components of the tobacco can be improved by using the boric fertilizer, so that the smoking quality of the tobacco is improved. The chloride ions can participate in photosynthesis in the tobacco plant body to maintain the osmotic pressure of cells, thereby improving the photosynthesis; promoting cell division, and when the tobacco plant lacks chlorine, the growth of the leaf is delayed, and the leaf area is greatly reduced; can also inactivate nucleic acid in tobacco mosaic virus, and has control effect on tobacco black shank and other fungal diseases.
Obvious interaction exists among various elements, the maturity of the flue-cured tobacco is influenced by high soil calcium, the leaves are rough and thickened, zinc and iron are disordered, and the absorption of the flue-cured tobacco to boron is reduced; the magnesium deficiency inhibits the absorption of nitrogen, phosphorus and potassium nutrients by tobacco plants; the lack of boron causes the poor development of the root system of the tobacco plant and influences the absorption of phosphorus and potassium; the high K/B ratio of soil aggravates the boron deficiency of the flue-cured tobacco, and the boron can promote the absorption of magnesium, manganese and molybdenum in the tobacco leaves and reduce the chlorine content in the tobacco leaves; the chlorine content is suitable for promoting the absorption of nitrogen, phosphorus, potassium and calcium.
In the production of flue-cured tobacco, the main way of making up the deficiency of potassium, magnesium, boron and chlorine in flue-cured tobacco is to improve the formula fertilization and the foliage spraying. The foliar fertilization is a one-time supplying mode of the nutrient elements of the tobacco plants, can compensate the deficiency of the nutrition absorbed by roots, has the effect of improving the tobacco quality, is an efficient method for top dressing outside roots, and is widely used in the production of flue-cured tobacco. In the wenshan karst tobacco field, because the land is seriously lost and lacks nutrition, the tobacco leaves are economic crops for collecting leaves, and in order to ensure that the tobacco plants need sufficient nutrition, when 8-12 new leaves grow out from the tobacco plants, the tobacco leaves are sprayed on the surfaces of the leaves, so that the tobacco leaves are easier to absorb and take effect quickly.
The karst soil has serious water and fertilizer leakage, and the potash feldspar soil conditioner is rich in silicon, calcium, magnesium and other nutrients and can provide nutrient components for crops for a long time. The potash feldspar soil conditioner has special gaps, oxygen-containing polar functional groups on the surface and certain ion exchange performance, reduces the loss of phosphorus and potassium in soil, and improves the colloid performance, ion exchange and adsorption capacity of the soil, so that the pH value of the soil and the contents of potassium, calcium and magnesium in exchange performance are improved, and the growth and development of tobacco plants are facilitated.

According to the analysis, the T5 and the T8 have the best effects on promoting the growth and development of the flue-cured tobacco and improving the structure grade, the yield and the output value of the tobacco.
2.4 Effect of Each treatment on the chemical composition of tobacco leaves
As can be seen from Table 5, compared with CK, the contents of total sugar and reducing sugar in T3, T7 and T8 tobacco leaves are respectively and remarkably reduced by 5.96-21.76% and 6.74-22.69%, and the contents of total sugar and reducing sugar in the rest treated tobacco leaves are respectively and remarkably improved by 8.76-20.12% and 5.24-25.37% compared with CK. The total nitrogen content of the T2, T4, T5, T6 and T9 tobacco leaves is reduced by 8.40-15.55% compared with CK, the total nitrogen content of the other processed tobacco leaves is increased by 1.68-8.82% compared with CK, and T7 is increased remarkably compared with CK.

From the chemical composition availability index (CCUI), CCUI of T2, T5 and T8 tobacco leaves is significantly higher than CK, and CCUI of other treatments is significantly lower than CK. The analysis shows that the potassium feldspar soil conditioner prepared by the magnesium, boron and chlorine fertilizers obviously increases the content of potassium, magnesium and boron in the tobacco leaves and improves the chemical component coordination of the tobacco leaves.
2.5 Orthogonal test optimization and evaluation
As can be seen from Table 6, the 4 fertilization factors have different effects on the tobacco yield and the chemical composition availability index (CCUI), the yield is C > D > A > B, namely, boron fertilization has the greatest effect on the tobacco yield, chlorine is used, soil conditioner is used, magnesium is used, and the optimal combined (A3B 2C1D 3) tobacco yield is 73108.65 yuan hm -2 (ii) a CCUI is B > D > A > C, the influence of magnesium application on CCUI is the largest, chlorine is used as the chlorine, a soil conditioner is used as the soil conditioner, boron is used as the boron, and the CCUI value of the optimal combined (A3B 2C1D 3) tobacco leaves is 85.24.
Conclusion
3.1 Influence of potassium feldspar soil conditioner prepared by magnesium, boron and chlorine on tobacco planting soil
In the study, compared with CK, the soil conditioner for magnesium, boron, chlorine and potash feldspar applied in the root zone increases the pH of the soil by 0.61-1.30 units to different degrees, and improves the contents of organic matters, hydrolyzable nitrogen, available phosphorus, available potassium, exchangeable calcium, exchangeable magnesium, available boron and water-soluble chlorine (table 2), which is consistent with the results of previous studies. The reason may be that: on one hand, the potash feldspar soil conditioner has special gap and surface oxygen-containing polar tube energyThe fertilizer has certain ion exchange performance, reduces the loss of phosphorus and potassium in soil, and improves the colloidal property, ion exchange and adsorption capacity of the soil, thereby improving the pH value of the soil and the contents of potassium, calcium and magnesium in the exchange performance. On the other hand, magnesium applied by different treatments changes the calcium-magnesium ratio and increases beneficial bacteria sphingomonas (B) and (C)Sphingomonas) The relative abundance and the activities of sucrase and catalase, wherein the potassium-decomposing bacteria release K in the clay mineral through the actions of acidolysis, chelation, anion exchange reaction, organic acid products and the like + 、Mg 2+ And Si 4+ The elements can fix nitrogen and improve the soil nutrition status, and simultaneously Ca 2+ 、Mg 2 + With NO 3 - 、PO 4 3- The synergistic effect exists between the two, so that the acidity of the soil is neutralized, and the effectiveness of the nutrients of the tobacco planting soil is improved; and the interaction of Mg, B and Cl obviously increases the content of soil hydrolyzable nitrogen, available phosphorus and available potassium. Therefore, in the production of flue-cured tobacco, the chemical behavior and the microbial activity of soil can be enhanced by supplementing the micro-fertilizer and applying the potassium feldspar soil conditioner, so that the process of adsorption-desorption of the micro-nutrients in the soil is developed towards the direction of increasing the content of the available nutrients in the soil, and the ecological and economic fertilization is realized.
3.2 Influence of potassium feldspar soil conditioner prepared by magnesium, boron and chlorine on photosynthetic property and yield and quality of flue-cured tobacco
Research shows that the micro-fertilizer and the potash fertilizer can regulate and control the activity of related enzymes, change the photosynthetic characteristic of plants, improve the potassium and magnesium contents of tobacco leaves, improve the quality of the tobacco leaves, promote the growth of tobacco plants through the interaction of magnesium, boron and chlorine, and increase the yield and output value of flue-cured tobacco; the silicon can regulate plant photosynthesis and transpiration, and the research also proves the conclusion (tables 3 and 4), particularly the effect of applying boron and chlorine fertilizers to improve the yield value of tobacco leaves is most obvious, and the effect is related to the serious shortage of effective boron and chlorine in soil in the test area. In comparison with CK, excessive magnesium application (treatment 9) reduces the tobacco yield (Table 4) and the tobacco chemical composition harmony (Table 6), which may be related to the high exchangeable calcium content of the soil to be tested, which seriously affects the absorption of magnesium and deteriorates the appearance quality of the tobacco; also, the yield of T3, T4 tobacco leaves is significantly lower than CK, mainly because the excessive chlorine application causes the internal quality and the external quality of the tobacco leaves to be negativeThe surface effect. The research also shows that compared with CK, the total sugar, reducing sugar, total nitrogen, nicotine, potassium oxide, chlorine, calcium, magnesium and boron of each processed tobacco leaf are improved to a certain extent, the chemical components of T5 and T8 in the tobacco leaf are better coordinated (Table 5), on one hand, the potassium feldspar soil conditioner possibly contains nutrient components such as potassium, magnesium, boron, silicon, chlorine and the like or the activated soil thereof (Table 2), the balance of the supply of trace elements in the soil is effectively improved, the absorption capacity of flue-cured tobacco on potassium and magnesium and the photosynthetic performance of leaves are promoted, and the total sugar, reducing sugar, starch accumulation and potassium transport of the tobacco leaf are promoted, and in the research, magnesium sulfate is applied to 225kg hm -2 The chemical components of the treated tobacco leaves are relatively poor in harmony, which is possibly equal to the magnesium content of the tested soil, and excessive magnesium application inhibits the NH of tobacco plants 4 + The absorption and the nitrate assimilation of the tobacco leaf are related to the reduction of the total nitrogen and nicotine of the tobacco leaf. In another aspect, anions such as NO 3 - 、H 2 PO 4 - 、Cl - With Mg 2+ The synergistic effect exists between Mg and Cl, and when Mg and Cl are applied in a matched manner, the Mg and Cl have opposite charges, so that a synergistic effect on the growth and the quality of flue-cured tobacco can be formed. The research only carries out a field test on the cohesive red soil for one year, and needs further exploration about the effects of Mg, B and Cl in the potassium feldspar soil conditioner on different soil types and soil textures, the aftereffect of flue-cured tobacco in the next year, the stability of soil aggregates and the influence of soil moisture loss.
In conclusion, in the karst flue-cured tobacco cultivation area, 150 kg/hm of magnesium sulfate is applied 2 Borax 15-30 kg/hm 2 60-90 kg/hm of potassium chloride 2 And potassium feldspar soil conditioner of 600-900 kg/hm 2 By the combination of the components, the pH value of the soil in the tobacco root zone and the nutrient supply capacity of main effective states can be effectively improved, and the problems of soil acidification in the karst tobacco zone and insufficient potassium, magnesium, boron and chlorine supply strength in the tobacco root zone are better solved; can improve the photosynthesis of the flue-cured tobacco, promote the growth and development, improve the economic benefit and the content of potassium, boron and chlorine in the tobacco leaves, improve the chemical component coordination of the tobacco leaves and have good popularization potential.
