Do you know the fertilization period of different plants?

Preface: Plants from sowing and flowering to entering the dormant period, for each plant will go through this stage, then different stages need different amounts of fertilizer, only if we take more care of these plants, will grow better. Different plants have different fertilization periods, so let's share with you how to fertilize.

Different types of plants have different fertilization methods, and the best season for fertilizing trees is after autumn, when an additional fertilization effect is the best. Plants grow better in the second year, and tree fertilization is mainly done in the spring. Organic fertilizer is the main fertilizer when fertilizing, and compound fertilizer can be applied according to the growth of trees in summer.

In the fall, you can increase the frequency of fertilization. For the fertilization of crops, it is necessary to give it sufficient environment before planting, and apply base fertilizer when sowing in spring. In summer, urea or cake fertilizer solution can be applied, and in autumn and winter, the frequency of fertilizer can be reduced.

There are many species of shrubs, and its main fertilization season is in the summer. Tall trees grow most vigorously in March and June, when liquid fertilizer is mainly applied. If it is a plant that blooms in early spring, apply fertilizer half a month before flowering.

Fertilization is mainly based on nitrogen fertilizer, and the amount of fertilizer should be reduced in summer. <>

Succulents, whether it is water or fertilizer, are not in great demand, so it is necessary to fertilize it as little as possible, and the main season for fertilization is also in autumn. During the summer heat, when the succulents are dormant or semi-dormant, fertilizing the succulents should be stopped. Most succulents should be fertilized once a month during the growing period.

Herbaceous plants should be fertilized according to the fertilizer requirements of different plants, generally in spring and summer, because this is the fastest growing period for herbaceous plants. Stop fertilizing in winter.

I know that every plant has a different fertilization period, and we need to understand it first, so that we can raise the plant well.

I know, and at the time of planting, we must ensure that the base fertilizer is sufficient, so we must supplement fertilizer in time, and in the process of planting, we must also choose the appropriate fertilizer for application according to the situation of the crop.

1. Fertilization of tree plants.

Different fertilization methods are also different, so what is the best season for tree plant fertilization, in fact, it is best to top dressing in autumn, so that the plants can grow in the next year to grow better, mainly in the spring to apply sufficient base fertilizer, mainly organic fertilizer, compound fertilizer is applied in summer according to the growth, and the number of fertilization can be appropriately increased in autumn.

2. Fertilization of crop plants.

General crop plant fertilization to give sufficient base fertilizer environment before planting, can be used in spring sowing time to apply bottom fertilizer, mainly organic fertilizer and superphosphate mixed fertilizer, summer can be applied thin urea or cake fertilizer solution, autumn and winter appropriate reduction on the line, fertilization can be added to the appropriate amount of herbicides.

3. Fertilization of shrub plants.

Shrub plants are also divided into many species, such as the fertilization of tree species on both sides of the road to nitrogen fertilizer-based, fertilization season is mainly in summer, generally grow tall trees, grow vigorously in March and June, mainly to apply liquid fertilizer, early spring flowering plants should be fertilized half a month before flowering, fertilization is mainly based on nitrogen fertilizer, and the amount of nitrogen fertilizer and phosphorus fertilizer should be reduced early in summer.

4. Succulent plant fertilization.

Succulent plants do not have a very large demand for fertilizer, generally try to apply as little nitrogen fertilizer, fertilization is mainly carried out in autumn, in the summer high temperature during the semi-dormant or dormant state, at this time should stop fertilization, autumn can be applied every 2 3 weeks liquid fertilizer, most of the succulents can be applied once a month during the growth period.

5. Fertilization of herbaceous plants.

Herbaceous plant fertilization should be carried out according to the needs of different plants for fertilizer, most of them are concentrated in spring and summer fertilization every year, at this time it is also the fastest growing period, spring and summer fertilization is mainly based on liquid fertilizer, fertilizer in late autumn do not apply nitrogen fertilizer, and fertilization can be stopped in winter.

We often wonder why fertilization didn't work as expected. Or is it that the fertilization is obviously applied but it does not work, what is the reason for this?

In fact, it is largely caused by improper fertilization methods, so what should we do to achieve efficient fertilization? What to look out for?

The following points should be paid attention to accurately grasp and apply this law in production practice:

1) The minimum nutrient is a relative type of car.

Crop yields are determined by the relative least amount of nutrients in the soil that require the crop relatively little, but not absolutely. That is, in the process of crop growth, if the supply of one or more essential nutrients is insufficient, the nutrient that is most lacking in the soil according to the needs of the crop is called the minimum nutrient.

2) The minimum nutrient is variable.

The minimum nutrients are not fixed and change, but vary with the conditions of production. When the minimum nutrients in the soil are supplemented by fertilization to meet the needs of the crop, the crop yield will increase with the replenishment of the nutrients under the new minimum nutrient limit, and the original minimum nutrients will give way to other nutrients that limit the growth and development of the crop.

3) Continuing to increase nutrients other than the minimum nutrients will not only make it difficult to increase the yield, but also reduce the efficiency of fertilization.

In production practice, if a large amount of a certain nutrient is used, crops will be extravagantly absorbed, poisoned by single salt, and seedlings will be burned, resulting in reduced yield and even no harvest. This phenomenon is more likely to occur when nutrients other than the minimum nutrients are used before the minimum nutrients are replenished. Therefore, when fertilizing, we should pay attention to the change of minimum nutrients and other nutrients to avoid blindly increasing the amount of fertilizer in production.

4) The minimum nutrient may be present at the same time for more than two.

That is, when two or more nutrients restrict crop growth, adding one or another nutrient may slightly increase yields, but using higher ratios will reduce yields. However, when the two nutrients are used together, yields can increase significantly.

The above is the problem we should pay attention to, as long as these points of attention are mastered, in order to achieve efficient fertilization, I hope to help everyone!

If you want to achieve efficient fertilization of crops, you must use the detailed rules to divide the fertilizer method, and put the fertilizer near Sun Chang, which can make it easier for the crop to absorb nutrients and not waste fertilizer.

According to the characteristics of agricultural infiltration crops and the demand for fertilizers, different fertilizers can be used in the stage of non-Qichangtong, which can be used in the way of deep digging, injections or hanging bottles.

I Heng Shi Zhi Hail teased, to choose the right fertilizer according to the type of rural species, to determine the appropriate fertilization time, before planting must ensure that the bottom fertilizer is sufficient, do not choose the wind or rainy days when fertilizing, to choose the right temperature.

First of all, when fertilizing, we must choose farmhouse fertilizer, do not use fertilizer bought outside, and we must use professional tools to fertilize when fertilizing, because this will bring us a lot of convenience, and when fertilizing, we must pay attention to the details of the slag and the problem of the bird, dismantling and building must not bring unnecessary trouble to yourself, but I think the most important point is that when fertilizing, you must use artificial fertilization.

You know, in fact, when planting, you should choose the right soil, but also choose the right fertilizer, spray the way to fertilize.

When applying nitrogen fertilizer, how do you understand "determining the amount of fertilizer to be applied and the period of application according to the characteristics of the plant"?

To solve this problem, we must first know the role of nitrogen fertilizer, simply put, nitrogen fertilizer is mainly in the leaves, nitrogen fertilizer is enough, the leaves are dark green and thick, if it is lacking, it is relatively thin, and if it is excessive, it is easy to grow branches and leaves, less flowering, and less fruit!

Knowing its characteristics, you know that it should be focused on in the early stage of plant growth, green leafy vegetables, plants, can be larger!

During the flowering and fruiting period, we should focus on phosphate and potassium fertilizers, and nitrogen fertilizers should be reduced!

Nitrogen fertilizer is the most used and frequently used in the crop production process because it has the strongest ability to regulate crop yield. The transformation of nitrogen fertilizer into the soil is complex and involves many processes such as chemistry and biochemistry. The interconversion of different forms of nitrogen causes fertilizer nitrogen to volatilize, escape and lose in the soil, which not only causes economic losses, but also may pollute the atmosphere and water.

Therefore, the rational and efficient application of nitrogen fertilizer is more and more important. 1. Rational distribution of nitrogen fertilizer The rational distribution of nitrogen fertilizer is mainly determined according to soil conditions, crop nitrogen nutritional characteristics and the characteristics of nitrogen fertilizer itself. 1. Soil conditionsSoil acidity and alkalinity are important bases for the selection of nitrogen fertilizer.

Acidic and physiological acidic fertilizers should be used for alkaline soils. This is conducive to improving the soil environment for crop growth through fertilization, and is also conducive to the improvement of the effectiveness of multiple nutrients in the soil to crops. Attention should be paid to avoid the application of fertilizers that can greatly increase the salinity of the soil on saline-alkali soil, so as not to cause adverse effects on crop growth.

In low-lying, flooded and other soils prone to strong reduction, ammonium sulfate and other sulfur-containing fertilizers should not be allocated to prevent the formation of harmful substances such as hydrogen sulfide, and nitrate nitrogen fertilizers should not be allocated in paddy fields to prevent nitrogen loss with water or denitrification and denitrification loss. 2. The amount of nitrogen fertilizer required by different crop types for different crop types is very different. Generally speaking, leafy vegetables, especially green leafy vegetables, mulberry, tea, rice, wheat, sorghum, corn and other crops need more nitrogen, and more nitrogen fertilizer should be allocated.

Leguminous crops such as soybeans and peanuts can carry out symbiotic nitrogen fixation due to their root nodules, and only a small amount of nitrogen fertilizer needs to be applied at the beginning of growth. Starch and sugar crops such as sweet potato, potato, sugar beet, and sugarcane generally only need sufficient nitrogen** in the early stage of growth to form an appropriate size of nutrients to enhance photosynthesis, while in the later stage of growth and development, too much nitrogen** will affect the accumulation of starch and sugar, but reduce yield and quality. Similar differences exist between different varieties of the same crop.

Fertilizer-tolerant varieties generally have higher yield and larger nitrogen requirements; Barren-tolerant varieties require less nitrogen and tend to have lower yields. 2. Determination of nitrogen fertilizer application rate, scientific research and practice have proved that with the increase of nitrogen fertilizer application rate, the utilization rate and yield increase effect of nitrogen fertilizer gradually decrease.

According to statistics, in 1993 and 1994, China's average consumption of nitrogen fertilizer per hectare of farmland was as high as 188kg, which was twice as high as the world average consumption level in the same period. In some economically developed areas, the economic losses and damage to environmental quality caused by excessive application of nitrogen fertilizer have reached very serious levels, and the restoration and rebuilding of good ecosystems will be extremely costly. According to the results of fertilizer field experiments conducted on major grain crops in some areas, on the basis of other elements such as phosphorus and potassium fertilizers, the nitrogen application rate (in N) of each crop is about 150kg hm, of course, the specific nitrogen application rate should depend on the specific conditions of each place.

In order to ensure the growth of crops, we need to fertilize crops and supplement nutrients during the growth process of crops, so how to fertilize? What is the basic basis for fertilization?

In order to achieve real and reasonable fertilization, in addition to mastering the necessary fertilization principles, we should also regard the influence of crop nutritional characteristics and environmental conditions on crop nutrition as an important basis for rational fertilization.

(1) Crop nutritional characteristics and fertilization.

The normal growth and development of all crops require carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, copper, zinc, boron, molybdenum, chlorine 16 essential nutrients, and the absorption of nutrients by crops has stages and continuity, which is called the commonality or generality of crop nutrition. However, different crops have different requirements for different nutrients, and we need to analyze specific problems in practice.

b) Soil conditions and fertilization.

The root system absorbs nutrients through the soil, and the nutrient content of the soil is an important reference for reasonable fertilization.

(3) Climatic conditions and fertilization.

Climatic conditions affect the condition of soil nutrients and the ability of crops to absorb nutrients, which in turn affects fertilization effectiveness. In areas or seasons with high temperature and rain, organic fertilizer decomposes quickly, semi-decomposed organic fertilizer can be applied, and the amount of fertilizer should not be too large, and fertilizer should not be too early, so as not to leach nutrients. In areas or seasons with low temperature and less rainfall, the decomposition of organic matter is slow and the fertilizer effect is delayed, so organic fertilizers with high degree of decay and fast-acting chemical fertilizers should be applied, and they should be applied as early as possible.

In alpine areas, it is advisable to increase the application of phosphorus, potassium fertilizer and ash fertilizer, which is conducive to improving the cold resistance of crops and helping crops to survive the winter safely.

(4) Characteristics of fertilizer varieties and fertilization.

There are many types of fertilizers, and the properties are also very different, and the properties of fertilizers must be taken into account in reasonable fertilization. The properties closely related to fertilization include nutrient content, solubility, pH, stability, mobility in the soil, fertilizer efficiency, after-effect size and whether there is ***.
