It is said that it is very important to apply basal fertilizer to fruit trees in autumn, how to appl

I think the first thing to do is to choose a good fertilizer, and then to apply fertilizer on time, and to fertilize in moderation.

I think the best effect is to fertilize the fruit trees at the right time.

In general, it is necessary to fertilize properly so that it can fully absorb the growth that is suitable for it.

Generally, when he is about to mature, these fertilizers should not be excessive.

Because the temperature difference between day and night in autumn is relatively large, after fertilization, it can improve the photosynthetic capacity of leaves and increase the generation and accumulation of organic matter. When fertilizing in autumn, the organic matter can get enough time to decay and decompose, and the degree of mineralization can be relatively high, and it can be supplied to the root system in time for absorption in the spring of the second year.

1. Able to quickly restore the tree's potential. The quality of the tree directly affects the yield of next year, and the tree needs a lot of nutrients as a result of the autumn fruit harvest, just like our lesbians need a lot of nutrients after giving birth, so some places are also called "confinement fertilizer", at this time the nutrients needed are not only nitrogen, phosphorus, potassium three large elements, but also calcium, magnesium, sulfur, copper, iron, boron, manganese, zinc, molybdenum and other trace elements;

2. Continue to promote flower bud differentiation. Autumn is an important period for the differentiation of flower buds of fruit trees, at this time, the photosynthesis of fallen leaves has not yet been good, so it is conducive to microbial decomposition and fruit tree absorption, and has unique benefits for the germination, flowering, fruit setting, high yield and high quality of fruit trees in the next year.

3. It is conducive to safe winter. Fruit trees with adequate nutrient storage and robustness have strong resistance to disease, cold and drought.

4. Able to retain water and fertilizer. The biological fertilizer in autumn fertilizer can not only meet the needs of crops for a variety of nutrients, but also loosen the soil, improve the soil environment, retain water, fertilizer, and resist drought, and the microorganisms in the fertilizer can also inhibit the survival and reproduction of harmful bacteria.

5. For old trees, weak trees, and diseased trees, they can cut off their rotten roots, rotten roots, and weak roots, and apply Aoli Feixing biological fertilizer, which can promote the growth of new roots and stimulate the vitality of new roots.

As a result of fruit harvesting, trees need a lot of nutrient supplementation, and basal fertilizer is the basis for improving the soil, improving quality, and storing nutrients for fruit trees.

Autumn is the first time the root system of fruit trees grows.

In the second and third peak periods, fertilization at this time, the absorption capacity of the roots is strong, the wounded roots are easy to heal, and the cutting off of some fine roots can promote the development of new roots. Root wounds heal quickly, and the promotion rate of new roots is high.

Fruit tree base fertilizer, to the farmer's rotting organic fertilizer, supplemented by compound fertilizer, at the same time with biological fertilizer is better, through the mass propagation and activity of microorganisms, can accelerate the decay of farm fertilizer, improve the content of organic matter Now our apple trees have fallen leaves, the nutrients of the leaves have returned, and the aboveground parts of the fruit trees have begun to enter the overwintering state. Fertilization of fruit trees should be based on the actual situation, according to local conditions, different fruit trees in different regions, different climates and different tree potentials, the fertilizer and proportion applied are different, and the fertilization methods will be different, remember that the fertilization of fruit trees should not be carried out, the time period of fertilization of fruit trees is usually from spring to autumn, and it is basically fertilized in the growing season of fruit trees, and the organic fertilizer is applied as the base fertilizer of fruit trees in late autumn and early winter, which can fully meet the nutritional needs of fruit trees in winter. I will take the most common apple tree as an illustration here, since the application of compound fertilizer for fruit trees is carried out in winter, it is best to carry out it before the orchard soil freezes in winter. My opinion is that now compound fertilizer should be used as little as possible, if you are planting fruit trees in a greenhouse out of season, you can still use fertilizer in such a special environment.

At this time, it is necessary to apply compound fertilizer, and the application of compound fertilizer in winter has a great impact on the growth of crops in the coming year. And the fertilizer effect of compound fertilizer is long, and when sowing in spring and then adding organic fertilizer, the growth of plants will show a very good trend. After the arrival of winter, a small amount of nutrients will flow back from the "small branches, large branches, trunk and roots" and accumulate and store in the root system.

It is not until germination in the spring that these nutrients return from the roots to the shoots.

There are three tutorials for fruit trees to need fertilizer throughout the year, the bottom fertilizer in September, the germination top dressing in March, and the fruit expansion top dressing in June. In these three fertilization processes, are very important, but the bottom fertilizer in September is more critical for young trees, you can use rapeseed withered or peanut withered 1 catty, add some trace elements, and then give 4 taels of balanced compound fertilizer, this period do not apply high-nitrogen compound fertilizer.

I think compound fertilizers are better. When fertilizing fruits in autumn, compound fertilizer can better promote the growth of fruit trees. It can promote fruit trees to produce more fruits, and can also promote the fat, deliciousness and sweetness of fruits.

It is better to use a compound fertilizer when fertilizing fruit trees in autumn, because the main purpose of autumn trees is to replenish their vitality and make them grow more vigorously.

I think it's better to use compound fertilizer because it makes our fruit trees grow bigger and it also makes the soil more fertile. Our hometown often uses compound fertilizer.

It is better to use compound fertilizer. Autumn application of base fertilizer is to ensure the fertilizer efficiency and fertility of the coming year, because autumn and winter are the dormant period of fruit trees, which do not need too many nutrients, and the characteristics of compound fertilizer are to fertilize the soil and trim the soil through the slow release of fertility, and the cost is lower.

The autumn fertilization of fruit trees is mainly organic fertilizer and bacterial fertilizer, supplemented by macro-element fertilizer and various medium and trace element fertilizers, of which organic fertilizer and bacterial fertilizer should account for at least 70% of the total amount of fertilizer. Among the large number of elemental fertilizers, nitrogen fertilizer can be applied slightly more than phosphorus fertilizer, and potassium fertilizer can be applied without or less. What kind of nutrient deficiency occurred last year, you can apply some medium and micro fertilizers in a targeted manner.

Relatively high-quality organic fertilizer has well-rotted compost, manure, circle manure, green manure, crop straw and human manure, chicken manure, etc., these organic fertilizers have a variety of nutrients required by fruit trees, and continuous use in large quantities can effectively improve orchard soil. It should be noted that these organic fertilizers need to be fully decomposed, otherwise there will be serious root burning and soil compaction during the fermentation process.

Before fertilizing, it is necessary to have an expectation of the orchard yield in the coming year, and it is advisable to increase the orchard yield by 10-15% on the previous average. According to the experimental results, generally 25 kg (pure nitrogen) and 10-20 kg of phosphate fertilizer can be used per mu of orchard, which can meet the normal needs of the orchard. Boron and zinc deficiency are common in orchards, and generally 50 grams of boron fertilizer and zinc fertilizer can be applied to each adult production tree.

When the correct fertilization method is to open a ditch between the rows to fertilize, make a ditch between the two adjacent rows of fruit trees, and apply the fertilizer in the ditch. Orchard autumn fertilization, is to improve the soil, improve tree nutrients, raise flower buds necessary measures, fruit tree nutrients for a year, the vast majority of the first in the autumn fertilization,

The purpose of autumn fertilization of fruit trees is to supplement the needs of fruit trees in this period, and also to ensure the normal physiological activities of fruit trees during this period. Autumn fertilization is different from spring and summer fertilization, so what are the particulars of autumn fertilization?

Autumn fertilization mainly depends on these points!

Fertilize according to the situation.

According to the situation, the main problem is that we need to supplement the corresponding elements in time according to the specific situation of the fruit tree. So how to choose according to the needs of the fruit tree? For example, for fruit trees that are weak, we should increase the amount of fertilizer.

According to the balance principle of nitrogen, phosphorus and potassium nutrient content, the compound fertilizer with appropriate ratio of nitrogen, phosphorus and potassium is selected according to the fruit tree. For example, Ramla special fertilizer, for example, nutrient deficiency has always been a common topic, we should also learn to understand the specific symptoms of nutrient deficiency in time, and then according to the lack of elements and targeted supplementation of medium and trace elements. Of course, in the process of fertilization, we must also grasp the combination of organic fertilizer and fertilizer; It is also necessary to achieve the combination of macro-element fertilizer and micro-element fertilizer.

In the process of fertilization, it is also necessary to pay attention to watering, so as to ensure that the combination of fertilizer and water can play the best effect.

Fertilize according to the amount needed.

Understand the soil conditions of your own fields in an all-round way, and grasp the amount of fertilizer according to its fertility. To put it simply, it is "how much is missing, how much is made up", so as not to apply too much of a certain element and cause some physiological problems that should not occur; It is common to see the vigorous growth brought about by partial nitrogen fertilizer. Orchards entering a stable fruiting period, first determine the target yield, and then determine the amount of fertilizer we apply.

If the target yield is high, autumn fertilizer should be applied in larger quantities; If the target yield is low, fertilizer is applied relatively little. The target yield is based on the average yield of the orchard in the previous 3-4 years, with an increase of 10%-15%.

Control the correct fertilization method.

This is very important in the current orchard production management, and the correct method is twice the result with half the effort for fertilization. The common fertilization methods include strip furrow application, annular furrow application, hole application, etc., and the first two fertilization methods are suitable for autumn fertilization. At the same time of fertilization, according to the specific situation of fertilization and the situation of the orchard, it is combined with watering.

When is the best time to apply basal fertilizer to fruit trees in autumn? What fertilizer is good for autumn fertilization of fruit trees? In autumn, the fertilization of fruit trees is mainly organic fertilizer and bacterial fertilizer, supplemented by a large number of elemental fertilizers and various medium and trace element fertilizers.

Nitrogen fertilizer is slightly more than phosphate fertilizer, and in a large number of elemental fertilizers, potassium fertilizer is applied no or less.

Generally, most of the autumn fertilization of fruit trees is the application of compound fertilizer, in fact, this is not right, the purpose of autumn fertilization of fruit trees.

Therefore, it is better to fertilize in autumn with the following fertilizers: biological bacteria organic fertilizer, biological fungus type medium and micro fertilizer, decomposed manure (must be rotted), and the ground is sprinkled with silicon-calcium-magnesium-type calcium fertilizer to adjust the soil, and the comprehensive application of these fertilizers will be better, I hope it can help you.

In early autumn (mid-August to late September), the application of basal fertilizer is the peak of the second (full fruit period) or the third (special period for young trees) of the root system of fruit trees, and the root regeneration ability is strong, and the roots below 1 cm in diameter can send out new roots 20 days after fertilization, absorbing soil nutrients and water, which is conducive to the safe wintering of fruit trees. In early autumn, the ground temperature is suitable, the soil moisture is large, the microbial activity is vigorous, the fertilizer is fast decomposing, the salinity is high, and it is easy to be absorbed by the root system, especially for the flowering and fruit setting of fruit trees in the spring of the following year. In early autumn, the autumn shoots of fruit trees have basically stopped growing, and after applying base fertilizer, their fast-acting parts can be absorbed and utilized by the root system, which can not only enhance the function of leaves, but also store most of the photosynthetic products in the tree, enrich the tissues and flower buds, and is conducive to the safe wintering of fruit trees.

At the same time, in the spring of the following year, the fruit trees germinated early, developed leaves quickly, the leaves were large and thick, the photosynthesis ability was strong, and the nutrient exchange period was not obvious, which was conducive to the flowering, fruit setting and flower bud differentiation of fruit trees. The retarding part of the base fertilizer, after autumn, winter and spring, part is also converted into nutrients that can be absorbed by the roots of fruit trees, and the fertilizer effect can be exerted in spring, which is conducive to the flowering, fruit setting and spring shoot growth of fruit trees. Practice has proved that the effect of basal fertilizer application in early autumn is obvious, the flowering period can be two days in advance, 1 2 stubble flowers account for 98, flowering is concentrated, easy to pollinate, and the fruit setting rate is high, while the fruit setting rate of basal fertilizer in late autumn is only.

Fruit trees have three important growth peaks in the year, absorbing a large amount of nutrients from the soil to replenish the nutrients of the tree and storing them. The three peak growth periods are from early to mid-March, late May to late June, and after mid-September. Autumn fruit tree fertilization, generally not suitable for the use of chemical fertilizer alone, to farm fertilizer soil miscellaneous fertilizer or organic fertilizer, with the use of chemical fertilizer, especially for fruiting fruit trees, generally can be with 9-10 months, in the periphery of the fruit tree root system to dig a ring ditch about 30-40 cm deep, about 50 cm wide.

<> someone has done such a comparative experiment--- there are two pear trees of similar size, one of which has been fertilized enough in the fall; The other tree was not fertilized with basal fertilizer. As a result, in the second year, the pear tree with sufficient base fertilizer was flourishing and fruitful; It is beneficial to improve soil structure and enrich soil. Many orchards in mountainous and hilly areas are generally barren and low in organic matter.

Even in enclosed fields and paddy field orchards, the organic matter content is not high, and it is necessary to continuously improve soil fertility to improve water retention.

The exact time varies depending on the type of fruit tree. After the harvest of apple and pear varieties with early-maturing varieties, the basal fertilizer application was best before the harvest of medium- and late-maturing varieties (September to October). It is advisable to proceed after the young tree has stopped growing at the new shoots. Peach trees and grapes can be fertilized from October to promote germination and differentiation, improve the fruit setting rate of fruit trees, and the physiological differentiation period of flower buds of deciduous fruit trees is in autumn, at this time, fertilization is beneficial and harmless, laying a solid foundation for the growth of fruit trees in the spring of the next year.

The tree body is a little hungry and needs to be fertilized in time to replenish nutrients, which is essential for the formation of flower buds, which are sufficient nutrients and form many flower buds and are full. In the coming year, there are many flowers and fruits, and the fruit grows quickly, the deformed fruit is small, and the size is uniform, and the yield will naturally be high. It is beneficial to replenish the nutrients of fruit trees.

After the fruit trees are harvested in autumn, the air temperature and ground temperature are still relatively high, and the higher temperature can promote the full decay and decomposition of organic fertilizer, which can be used to supplement the nutrients consumed by the tree body, restore the tree potential, and accumulate nutrients.
