Why do you use foliar fertilizer for flue cured tobacco? What else can be fertilized?

With the development of flue-cured tobacco production and processing industry, the requirements for the quality of flue-cured tobacco are getting higher and higher, which requires farmers to pay attention to the production of flue-cured tobacco. When growing flue-cured tobacco, do you know how to improve the yield and quality of flue-cured tobacco? How to fertilize flue-cured tobacco can improve the income of flue-cured tobacco, the following is a detailed introduction.

Friends who want to know don't miss it. 1. How to manage the increase in flue-cured tobacco production? In the process of flue-cured tobacco planting and management, it is necessary to standardize the on-site management of flue-cured tobacco and optimize the planting technology of flue-cured tobacco.

When planting flue-cured tobacco, decide on the planting area and plot treatment, deal with the planting plot of flue-cured tobacco in advance, carry out deep ploughing, fertilization, ridge cultivation and other management points in a timely manner, improve the soil environment, prevent flue-cured tobacco diseases and pests, and soil moisture on site In addition, it is necessary to pay attention to the seedling management of flue-cured tobacco, and determine the construction and use plan of the nursery warehouse to ensure that the plot for planting flue-cured tobacco has a flat terrain, sufficient lighting, high terrain, good ventilation, sufficient water supply, convenient drainage facilities, and smooth ventilation The transplantation of tobacco seedlings should be carried out after the excavation of tobacco seedlings is completed, You can choose to transplant in trays, pump the seedlings to the roots, pack them, transport them to the field, and strengthen the shade when the tobacco seedlings are transported. You can choose to transplant early in the morning and in the evening.

Cloudy days can be transplanted all day. Second, which kind of leaf fertilizer is used to increase the yield of flue-cured tobacco? When fertilizing flue-cured tobacco, it is necessary to pay attention to the nutritional balance, to provide reasonable fertilizer ** and regulate the various nutrients required for the growth of tobacco plants in a timely manner, according to the soil fertilization, soil type, texture, depth of tillage layer and nutrient deficiency, the key points of fertilizer need are also different.

According to the principle of variety fertilizer, understand the difference of nutrient requirements of different tobacco varieties, spray Kunlun and wind-leaf cotton fertilizer in time during the growth period of tobacco, supplement the nutrients required for tobacco growth, and spray tobacco in time, two or three times. Tobacco helps to increase yield and improve quality.

Foliar fertilizer for flue-cured tobacco is mainly due to the characteristics of tobacco leaves, and flue-cured tobacco mainly relies on tobacco leaves to improve income, and the larger and stronger the tobacco leaves, the more abundant the harvest. Foliar fertilizer sprayed on tobacco leaves can make tobacco leaves better and more evenly absorbed, and the effect is better than direct fertilization into the soil. In addition to the common foliar fertilizer, flue-cured tobacco can also be applied with high-potassium and sulfur-based fertilizers.

In order to ensure the smooth growth and development of crops, many farmers will apply well, apply sufficient base fertilizer, and will carry out top dressing in stages, in order to have a higher yield and better quality of flue-cured tobacco at the time of harvest, through foliar spraying and extra-root fertilization, it can be supplemented with various nutrients in the middle and late stages of flue-cured tobacco growth, usually as long as the foliar fertilizer is used scientifically and reasonably, flue-cured tobacco will significantly increase yield and improve quality in the later stage.

Potassium dihydrogen phosphate is a phosphorus-potassium compound fertilizer with a nutrient content of up to 86% (52% phosphorus and 34% potassium), which is now called "god fertilizer" or "universal fertilizer".It can not only promote fruit swelling and color change and crop metabolism, but also improve the rooting, frost resistance and stress resistance of crops. Its wide range of use, strong adaptability, excellent use effect, sought after by the majority of users, once called "universal fertilizer", although it is a good thing, but also can not be used blindly, in the crop growth cycle to control the number of use, the general spraying control in 2 3 times is appropriate.

But it must be absorbed by the foliage of the crop. Therefore, its absorption and utilization is limited, and it must be matched with the appropriate concentration to be absorbed by crops. If the concentration is too large, it will cause waste and the crop will not be able to absorb it.

The preparation concentration is too low, labor-intensive and time-consuming, and it cannot play its due role. My apple trees are generally sprayed 2 4 times according to the situation when spraying potassium dihydrogen phosphate every year, which is not to say that it can only be sprayed two or three times, but it is useless to spray more, spraying several times according to the growth of crops and the demand for nutrients to decide, spraying more may have the opposite effect.

When using potassium dihydrogen phosphate, the concentration of dilution is very important, usually spraying the foliage, and the effect of spraying the foliage is good, the effect is fast, during the growth period, often spray the foliage with 0.3% potassium dihydrogen phosphate solution, which can make it strong and leafy, and the flowers are colorful. In the jointing period of grain crops, budding stage, booting stage, grain filling stage, the use effect is good, the yield increase is 10% to 40%, the number of spraying is not necessarily 2 to 3 times, it can also be used many times, according to the type of crop and the length of the growth period, it can be used once every 8 to 10 days.

In fact, there is no hard and fast rule that potassium dihydrogen phosphate can only be used two or three times a year, and potassium dihydrogen phosphate is often used in orchid planting, and it is normal to use potassium dihydrogen phosphate 2-4 times a year. The reason for this statement is that it is considered from two aspects.

Flue-cured tobacco uses light carbon nuclear fertilizer, which needs to be fertilized a total of 3 times. Because the use of light carbon nuclear fertilizer is particularly good for growth, and the taste of the most flue-cured tobacco is very good.

When fertilizing flue-cured tobacco, we should pay attention to the nutrient balance, timely fertilize the flue-cured tobacco reasonably and adjust the various nutrients necessary for the growth of tobacco plants, and also pay attention to the fertilization due to the soil, and the fertilizer requirements of different soil types, textures, depth of tillage layers, and nutrient abundance and deficiency are also different.

Pay attention to the principle of fertilization according to the variety, understand the difference in the demand for nutrients of different flue-cured tobacco varieties, spray Kunlun foliar fertilizer in time during the growth period of flue-cured tobacco, supplement the nutrients required for the growth of flue-cured tobacco, spray flue-cured tobacco in time, and spray two to three times is better, which can help increase the yield and quality of flue-cured tobacco.

Foliar fertilizer such as potassium dihydrogen phosphate is used for flue-cured tobacco. A total of 2-3 fertilization sessions are required.

Dear, hello, this can use trace element water-soluble fertilizer, it is a chlorine-resistant plant, so you can't use potassium chloride, if you want to use it, potassium supplementation should supplement potassium sulfate. In addition, the nitrogen fertilizer of Bimo is the majority, followed by potassium fertilizer, and phosphate fertilizer is relatively stable. During the growth period, the early stage is rich, and the old is poor.

Generally, when the leaves are about to grow green, use a top dressing, and then foliar fertilizer.

A new day begins, good morning! Pro, you can consider using fertilizers that are high in nitrogen, phosphorus, and potassium, such as compound fertilizers or organic fertilizers. Among them, nitrogen fertilizer can promote the growth of tobacco; Phosphorus and fertilizer can improve the quality and stress resistance of tobacco; Potash fertilizer can increase the disease resistance of tobacco.

At the same time, excessive fertilization should be avoided so as not to cause diseases and quality problems of tobacco in jujubes. Tobacco is a crop that requires high fertility, and if there is not enough nutrients in the soil, it will directly affect the growth and quality of tobacco. Therefore, it is necessary to supplement the fertilizer at the right time during the tobacco growth period.

For the case of tobacco leaves not growing, in general, two to three fertilizers need to be applied during the tobacco growth stage, of which the first fertilizer should be applied before planting to provide a reserve fertilizer; The second fertilizer should be applied during the peak growth period of the tobacco; The third fertilizer should be applied during the flowering and fruiting period.

Hello dear friends! You want to know about the question of whether flue-cured tobacco foliar and phosphate fertilizers are toxic, glad you did. Flue-cured tobacco foliar fertilizer is a kind of homemade nitrogen fertilizer, composed of flue-cured tobacco leaves, chickpeas, soybean meal, oil cake, phosphate fertilizer, with high nitrogen, high phosphorus, medium potassium, low moisture, due to the variety of composition, even if there is a small amount of toxic substances in the oil cake, it is composed of a variety of fertilizers (phosphate fertilizers), and will not transmit toxic substances.

However, in some places, due to environmental reasons, such as heavy metal pollution in the soil, these toxic substances may contaminate flue-cured tobacco leaves and other materials, which will affect its quality, therefore, before using flue-cured tobacco foliar fertilizer, it is necessary to carefully check the purchased flue-cured tobacco leaves to confirm whether there are toxic substances, so as to ensure the safety and reliability of the quality of the flue-cured tobacco foliar fertilizer used at the end. In addition, phosphate fertilizer itself is non-toxic and does not pollute the environment. In general, as long as it is used correctly, flue-cured tobacco foliar fertilizer and phosphate fertilizer will not be toxic.

Is there anything else you would like to ask.

Hello, phosphate fertilizer is an important phytonutrient that promotes the growth and development of plants. Flue-cured tobacco foliar fertilizer is a fertilizer that contains a variety of nutrients that can provide nutrients for flue-cured tobacco. However, whether flue-cured tobacco foliar fertilizer can be used as phosphate fertilizer needs to be analyzed on a case-by-case basis.

First of all, whether there is enough phosphorus in the foliar fertilizer of flue-cured tobacco is a key question. If the phosphorus content in flue-cured tobacco foliar fertilizer is high enough, then it can be used as a phosphate fertilizer. However, if the phosphorus content in the foliar fertilizer of flue-cured tobacco is insufficient, then the use of it as a phosphate fertilizer may affect the growth and development of flue-cured tobacco.

Secondly, whether flue-cured tobacco foliar fertilizer is toxic is also a question that needs to be considered. If flue-cured tobacco foliar fertilizer contains toxic substances, then using it as a phosphate fertilizer may have adverse effects on flue-cured tobacco. Therefore, before using flue-cured tobacco foliar fertilizer as a phosphate fertilizer, adequate testing and analysis are required to ensure its safety and effectiveness.

In summary, flue-cured tobacco foliar fertilizer can be used as a phosphate fertilizer, but it needs to be analyzed and tested on a case-by-case basis to ensure its safety and effectiveness. At the same time, it is necessary to pay attention to whether flue-cured tobacco contains toxic substances in the foliar fertilizer stove to avoid adverse effects on the growth and development of flue-cured tobacco. Argument liquid.

It is better to apply well-rotted organic fertilizer and potassium fertilizer to high-quality flue-cured tobacco. Flue-cured tobacco planting can not apply more nitrogen fertilizer, should be applied high potassium content compound fertilizer. Organic fertilizer and compound fertilizer with high potassium content are required to grow flue-cured tobacco.

In the later stage, phosphorus and potassium fertilizers were the main fertilizers, and the effect was relatively good. The principle followed by flue-cured tobacco fertilization is "basal fertilizer, top dressing supplemented, and top dressing according to seedlings", so as to achieve "reasonable collocation and balanced fertilization". However, in the fertilization operation, it is easy to ignore some links, or there are some misunderstandings, which is not conducive to the growth of tobacco plants.

Therefore, timely and appropriate fertilization, mastering certain application skills, is the key to improving tobacco quality, in the flue-cured tobacco fertilization, pay attention to the following four aspects.

One. Balanced fertilization to promote the growth of tobacco plantsIn the production of flue-cured tobacco, chemical fertilizers are widely used, but single fertilization or excessive fertilization are not conducive to the growth of tobacco plants. Only the amount of farmhouse fertilizer or chemical fertilizer is too small, the tobacco stem is thin, the tobacco leaves are small and thin, the yield of tobacco leaves is low, and the excessive fertilization will make the tobacco leaves greedy for green and late maturity, it is difficult to grasp the baking link, and it is easy to produce inferior tobacco that loses economic value, and the effective yield is not high.

Farmhouse fertilizer and compound mu of Hefei should be used as the main fertilizer, with potassium fertilizer, phosphate fertilizer and other trace elements, mixed and matched, balanced fertilization, and promote the vigorous growth of tobacco plants.

Two. Pay attention to the spacing, to avoid the phenomenon of "burning roots" in flue-cured tobacco fertilization, this phenomenon is easy to be ignored, and it is easier to occur, the fertilizer is too close to the rhizome, the concentration is too high, it is easy to cause root rot and other fertilizer damage, and the phenomenon of "burning roots" occurs, and the fertilizer is too far away and the tobacco plant is difficult to absorb. According to the growth status of tobacco plants, it should be applied about 15 cm from the root of the tobacco plant and stem, covering the loose and moist soil to ensure the ventilation of the tobacco plant, on the one hand, to avoid the phenomenon of "burning roots", and on the other hand, it is conducive to the absorption of tobacco plants.

Three. According to the conditions of the field, the differentiated fertilization tobacco fields mainly include purple soil, sandy loam soil, file macro, paddy field, dry land and mountainous land. According to the soil conditions and the fertility of the tobacco field, combined with the weather conditions, the fertilization should be differentiated, generally speaking, the amount of fertilizer in the paddy field is more, and the purple soil is less.

In addition, depending on the growth status of tobacco plants, appropriate topdressing or foliar fertilizer spraying, mainly potassium fertilizer, phosphate fertilizer and other trace elements, to avoid "no difference" fertilization.

Four. In order to facilitate the operation or reduce labor, there is a one-time fertilization phenomenon in the production of flue-cured tobacco, that is, the fertilizer required by the tobacco plant is applied once and again, and the top dressing is no longer carried out in the later stage. Although this fertilization method can guarantee the nutrients required in the early stage of tobacco plants, the fertilizer has a certain effective period, the growth cycle of flue-cured tobacco is long, and the nutrients required in the later stage of tobacco plants are difficult to guarantee.

Fertilization should be applied 2 or 3 times to ensure the supply of nutrients at each growth stage of tobacco plants, and the amount should be less and more than once, and fertilization should be carried out scientifically.

Tobacco is a potassium-loving crop, the demand for potassium is greater than that of nitrogen and phosphorus, the types of tobacco are different, the growth environment is different, the amount of nutrients absorbed and the proportion of mu are also different, the general trend is that nitrogen and potassium are more searching, and phosphorus is less. The absorption of nutrients by tobacco leaves is as follows: less absorption in the early stage of growth, the largest absorption in the middle stage, and gradually decrease in the later absorption.
