What soil is flue cured tobacco suitable for planting, and what are the soil requirements for flue c

Soils containing bio-organic fertilizers are more suitable.

Bio-organic fertilizer is an organic fertilizer made from organic solid waste (including organic waste, straw, human, livestock, poultry manure, cake meal, agricultural and sideline products and solid waste from food processing) after microbial fermentation, deodorization and complete decomposition.

Rich in a variety of functional microorganisms and rich trace elements, it can improve the soil structure, indirectly kill roundworm eggs and root nematodes, play a role in nutrition, conditioning and health care for crop growth, and let the land absorb organic matter to play a greater role.

It is suitable for the growth of flue-cured tobacco under various soil types.

The key is to use the soil wisely and take care of it. Adhere to the development direction of modern organic tobacco agriculture, rational application of high-quality and high-efficiency organic fertilizer in tobacco fields, the implementation of green manure to cover the green, the implementation of straw returning to the field, the cultivation of the soil environment for the production of high-quality tobacco leaves, provide a favorable soil environment for the growth of flue-cured tobacco, lay a solid foundation for the development of modern tobacco agriculture, and improve the quality of tobacco leaves.

Flue-cured tobacco should be planted at an altitude of 600 to 1000 meters, with medium or higher soil fertility, a slope of less than 30 degrees, good light conditions, and smooth drainage. The altitude is 600-1200 meters, the altitude, soil and climatic conditions are more suitable, and it is the best suitable area for flue-cured tobacco planting. The cultivation of flue-cured tobacco needs to be planted at an altitude of more than 800 meters, and the temperature difference between day and night is large to be suitable for the growth of flue-cured tobacco.

1) Temperature tobacco has a wide range of temperature adaptation, and can grow from 8 to 38.

2) Insufficient and too strong light is not conducive to the quality of tobacco leaves. Rainfall flue-cured tobacco leaves are large and require a lot of water. Moisture conditions are closely related to the growth and development of flue-cured tobacco and the yield and quality.

Tobacco is a temperature-loving crop, which can be grown in 8-38, and the optimal temperature is 25-28. Tobacco requires more water in the early and middle stages and less in the later stage. Tobacco planting requires sufficient sunshine, no wind and hail weather, the temperature is 25 28 is the most suitable, the field water holding capacity is maintained at 70% in the early growth stage, 80% in the middle stage, and 60% in the field water holding capacity from budding to maturity stage.

The soil is preferably laterite, followed by red loess, sandy soil, and bihetic soil.

China's tobacco is widely distributed, Henan, Shandong, Yunnan, Gansu and Hunan provinces are important flue-cured tobacco producing areas in China. Among them, Henan is the largest flue-cured tobacco production area in China, and its output accounts for 1 3 of the country, mainly distributed in Xuchang, Nanyang, Zhoukou and Zhumadian. Shandong flue-cured tobacco is mainly distributed along the Jiaoji Railway from Weixian to Zibo, with Yidu and Linqu in Changwei area being the most concentrated.

The quality of flue-cured tobacco in Yunnan is the best, distributed in Qujing, Yuxi, Zhaotong and other places.

Due to the different transplanting seasons in the southern tobacco area, there are spring tobacco, summer tobacco, autumn tobacco and winter tobacco. South China is dominated by spring tobacco. In Guangdong, Fujian and other areas with abundant heat, there are also a small amount of autumn and winter smoke.

almost 3,111 yuan per mu; On average, if there are more than 50 mu, the cost is 2,000 yuan per mu, and the net income per mu is more than 1,000 yuan; More than 20 acres, the cost per mu is about 1,300 yuan, and the net income per mu is about 1,800 yuan.

The quality of tobacco is different, and "good is caused by the local climate". The ancients believed: "The tobacco leaves of the sand fields are thin, and the tobacco leaves of the mountain fields are withered."

The root growth depends on the fertility of the land, and the air is thick and half borrowed from the soil plaster", where it is planted in the thick, loose, and well-drained land, the growth is good, and the tobacco planted in the mountains and fields has poor growth, and the taste of the tobacco grown in different places is not the same. Only newly cultivated wasteland can be planted once, but the top ears laid in the first year must be "left behind", otherwise it will also get the plague. Therefore, tobacco planting must be changed every year, generally every 3 years, and replanted once, so that the capital investment in the early stage will be very high.

Cultivation techniques. Identify the soil quality.

Only newly cultivated wasteland can be planted once, but the top ears laid in the first year must be "left behind", otherwise it will also get the plague. Therefore, the land must be changed every year, generally at an interval of 3 years, and once again.

Seedlings are planted. Before and after the winter solstice, choose a fertile plot, hoe digging and rake flat, spread a layer of coke ash, about 5 points thick, and then use pure fertilizer to evenly splash, and then sprinkle the tobacco seeds on the ash soil, about half a month, the seeds germinate, to around February, before planting and then splash again, after such careful cultivation, the seedlings are fat and easy to live.

Soil preparation and fertilization. Plow the ground 1 or 2 times before planting to loosen the soil and remove weeds, and then make a furrow. In addition, the furrow should be made in the shape of a turtle's back, easy to drain, 1 plant per hole, 2 feet apart between the rows, the hole is first put into the oil cake, and then covered with a layer of plant ash. The amount of oil cake application can be determined according to the fertility of the soil.

After the beginning of spring, after the sun and rain drenched oil cake rotting, you can transplant tobacco seedlings.

Before and after the transplanting valley rain, the seedlings grow 3 5 leaves, about four or five inches high, and can be transplanted on rainy days. Before planting, the roots of the seedlings should be on the soil, not all on the oil cake, if it is sunny, you can use the ratio of 1:9 fertilizer to water, watering for 3 days, until the seedlings are alive.

Personal advice. If you only plant a few acres, then forget it, because there is little time to do other things when planting, and it is particularly bitter, you want to plant a variety of plants, or you don't plant anything, an acre of tobacco bureau stipulates about 1,100 plants, the investment is about half of the income, everything is normal and can be sold for about 4,000 yuan, you have to rely on God to eat, beg not to hail, waste at once, don't have floods, don't have too serious drought, hey, nothing is easy to do.

Now there are two kinds, one is cloud smoke, which is high-yielding tobacco, and the other is the base 84 universal type of tobacco, and now tobacco under this condition is rarely bitten by insects.

Look at the quality of the soil The fields that have been planted with tobacco for many years are to prevent fahuo, and the baked tobacco is about 400 catties, which is considered good, and the average price is 11 yuan.

Tobacco is very tired, but the benefits are very good, and baking and everything requires technology.

About 1,200 are planted in one acre of good fields.

Some are expensive and some are cheap, it's hard to say, you have to see it before you know.

The best varieties are Yunyan 99 and 97

Summary. What are the soil requirements for flue-cured tobacco planting? : The main thing is that the pH value in the soil should be suitable for the growth of flue-cured tobacco.

The soil is required to be neutral and alkaline, and the soil should not contain a large amount of chloride ions. For the growth of smoke under the grass, the soil requirements are relatively strict, with red soil as the best, followed by red loess, sand and two soils, and black soil is the worst.

What are the effective precautions for flue-cured tobacco, commonly known as "playing **"?

1) Strengthen the management of seedlings in the later stage, strengthen seedling refining, and enhance the drought resistance of tobacco seedlings by cultivating strong seedlings. The first is to control water and fertilizer, and ensure that the seedling color is light green and the nutrient supply is controlled to meet the transplanting standard; the second is to standardize the number of leaf cutting up to 4-5 times; Third, do not remove the insect net during the seedling refining process to prevent aphids from spreading the virus; Fourth, apply the dowry medicine, 2 3 days before the tobacco seedlings are transplanted into the field, spray the dowry medicine once, and transplant with the medicine. (2) Strictly control the quality of transplanting and do a good job in the prevention of pests and diseases

Choose strong seedlings without diseases and insects for transplanting. When taking seedlings, it is necessary to select strong seedlings of the same size for centralized transplanting, eliminate weak seedlings, and strictly prevent weak seedlings from being planted in the field. When transplanting, it is found that common mosaic disease, bushtop disease, and black shin disease should be removed in time.

In the early stage of the field, the diseased plants were uprooted in time and the healthy seedlings were replanted. In particular, when common mosaic disease is operated in the field, it is necessary to disinfect hands and tools with soapy water. Strictly disinfect the seedling transportation tools, and pay attention not to damage the rhizomes and leaves during the transportation of tobacco seedlings to avoid causing wounds and causing infection.

2.Transplant at the right time. Flue-cured tobacco transplanting strictly implements the pre-finishing geographical moisture acceptance and seedling system, and comprehensively implements the transplanting technology of "high stem and strong seedlings, pull line positioning, water with fertilizer, and dry soil covering".

Focus on grasping five links: first, remove excess leaves before transplanting, leave two half leaves and one heart leaf, effectively reduce leaf water transpiration, conducive to seedling protection; The second is to plant tall stems and strong seedlings deeply, and the exposed moisture surface of tobacco seedlings after transplanting is not higher than 2 cm, so as to eliminate tall seedlings; the third is to strictly transplant with fertilizer to promote the early growth and rapid development of tobacco seedlings; Fourth, it is necessary to water enough root water, and each tobacco seedling is not less than 4 5 kg to ensure that the tobacco seedling is transplanted and survives; Fifth, the dry soil should be covered tightly, and the membrane mouth should have a large bowl mouth, so as to reduce the evaporation of moisture and prevent high temperature seedlings. Sixth, balanced fertilization of tobacco plants.

Nitrogen control, phosphorus and potassium increase, increase micro-fertilizer, and combine the regulation of water and fertilizer. Pay attention to early topdressing, so that tobacco plants grow early and develop quickly, create conditions that are not conducive to disease infection and epidemic, and improve the disease resistance of tobacco plants.
