Detailed explanation of high-yield fertilization techniques for peach trees and quick collection

As we all know, all crops need to be fertilized if they want to grow well. Only when fertilization is done in place, it is difficult to not produce high yields. So is fertilization the more the better? The answer is wrong, fertilization does not have to be more, but you need to pay attention to skills, master the law of fertilization, according to the different growth stages of plants apply different fertilizers, peach trees are common species in life, its growth can not be separated from fertilizer, the following together to understand the peach high yield fertilization technology points.

1. Benefits of compound fertilizer

Compound fertilizer is suitable for base fertilizer, which takes effect slowly and needs to be transformed once or twice.

1. Ammonium nitrogen is transformed into nitrate nitrogen before it can be absorbed and utilized by crop roots. Generally alkaline. The lower the temperature, the slower the transformation. It takes 15~20 days or more to apply in early spring. The transformation accelerates with the temperature increasing gradually. Summer only takes about 7 days, according to its characteristics, only suitable for base fertilizer, fertilizer efficiency for more than 90 days.

2, sulfur-based compound fertilizer generally refers to nitrate nitrogen compound fertilizer is acidic fertilizer, root absorption faster, early spring temperature low 7~10 days, summer temperature high 3~5 days can be fully absorbed by the root utilization, through the leaves converted into organic nutrients for plant growth. Can also do base fertilizer, can also do topdressing, more suitable for crop topdressing. The fertilizer effect lasts for more than 60 days, so it is not suitable for topdressing and nourishing fruit trees at all stages. Such as: peach expansion period topdressing, more than a month mature, late, the role of it does not work, when the full play of the role of the peach has matured, do not expand fertilizer effect outstanding. Especially early maturing varieties, mature early, late growth is still very long. For example, mature peaches in late May and June, late fertilizer strength is still very sufficient, only long strips, easy to cause deterioration of light, affect flower bud formation and quality, resulting in a large amount of fertilizer consumption and waste.

2. What are the types of organic nutrients?

Mengli 28, biological enzyme is an organic nutrient fertilizer, that is to say, it can directly supply, bloom and grow new shoots without leaf processing, make up for the shortage of stored nutrient energy and shorten the nutrient transformation period. Organic and inorganic (water-soluble fertilizer) can improve fertilizer utilization rate and promote healthy growth of fruit trees at various stages of growth, and the fertilizer efficiency can reach 25~30 days.

3. What are the characteristics of water-soluble fertilizer?

It is characterized by: can promote crops to take effect quickly, timely supply fruit tree growth of various elements, supplement a certain period of element energy deficiency, to achieve the maximum utilization of fertilizer efficiency. The fertilizer effect is only more than 20 days. However, it is necessary to understand the characteristics of each water-soluble fertilizer and the characteristics of fruit growth and development in order to exert the maximum effect. He could not ignore what he needed and chase after what he did not need.

4. What fertilizer is good for autumn basal fertilizer selection?

In general years, fruit trees and peach trees in Yuncheng area enter the autumn shoot stop period in late August, fruit trees enter the third root growth peak, peach trees enter the second root growth peak, if it is a late-maturing variety, it can not only supply fruit growth but also enter the storage nutrition stage, tree vigor is not strong, flower bud differentiation is good, depending on this autumn management (autumn basal fertilizer and autumn shear). Base fertilizer is also called base fertilizer, so people often say: three chase is not as good as one bottom, indicating the importance of autumn base fertilizer. In fertilizer selection, we must choose the formula fertilizer with long fertilizer efficiency period and complete nutrition. In order to increase soil fertility, we must apply more decomposed farm manure or organic biological fertilizer to improve the aggregate structure of soil, increase soil permeability, meet the growth conditions of root system, promote root system growth, which not only can meet the supply of autumn nutrition, but also can supply fertilizer and nutrition required by fruit tree growth season in the second year.

5. Why do you want to chase water-soluble fertilizer during the growth period?

Fruit trees, peach trees in the whole growth stage, flowering-young fruit stage, this period is mainly consumed by the storage of nutrients, generally about a month. The first big leaf is formed in the first and middle of May, and then enters the nutrition utilization stage of the current year. At the same time, it enters the fruit hard core stage. There is no leaf on the compound fertilizer before flowering, so it cannot be utilized at all. The fertilizer effect is too long for more than 60~90 days. Too much nitrogen fertilizer is not conducive to nuclear hardening and lignification of branches. Therefore, organic nutrient fertilizer and water-soluble irrigation fertilizer must be selected, which has faster effect and better effect. It is not wasteful and scientific and reasonable. The three elements and medium and trace elements change in the expansion period. Therefore, different element fertilizers must be supplied in time according to the fertilizer requirements of different fruit trees and peach trees in different periods in order to meet the normal and healthy growth of fruit trees and peach trees.
