What fertilizer is applied to peaches to increase their sweetness?

Whether the selling price of peaches is high or not, one depends on the appearance quality, and the other depends on whether the taste is sweet. However, many growers have encountered the situation that peaches are sour and tasteless, which affects sales and even affects the selling price. What should I do if the peaches are too sour?

What fertilizer to make peaches sweeter? Let's take a look!

Yellow peach with poly Wuba super potassium calcium magnesium water-soluble fertilizer.

1. Balanced nutrition.

Peach trees of different ages have different nutrient requirements, so it is necessary to balance fertilization according to the age of the tree. Young trees are mainly nitrogen fertilizer, appropriate application of phosphorus and potassium fertilizer, diligent and thin application; The initial fruiting trees should control nitrogen, increase phosphorus, and supplement potassium; Nitrogen, phosphorus and potassium formula fertilization at the peak fruit stage. Excessive application of nitrogen fertilizer and application of fast-acting nitrogen fertilizer before fruit ripening will affect fruit color and reduce fruit sugar content.

Phosphate and potassium fertilizers are conducive to the accumulation of sugar and the formation of protein, and increase the coloration of fruits. In the orchard where organic fertilizer is fully applied, the effect of increasing yield is obvious when combined with the application of phosphate fertilizer and potassium fertilizer. The nutrients in organic fertilizer are relatively comprehensive, and the application of organic fertilizer can improve the sugar content and flavor of the fruit, and promote the coloring of the fruit.

2. Improve lighting.

For peach trees, the higher the middle and upper parts of the canopy, the larger the fruit, the better the coloring, and the higher the sugar content. Compared with the fruit branches in the canopy closure, the sugar content of the fruit branches with good light is generally 10-20. Therefore, 60% of the fruit should be distributed in the middle and upper parts of the canopy, and 40% in the lower part.

Therefore, if the sugar content of peaches in other parts is not too low, it is necessary to take reasonable dense planting and cultivate a good tree shape, so that each fruiting branch group of the tree can get more than 3 hours of direct light every day. In addition, it can also be applied with reflective film to increase the coloration of the fruit and increase the sugar content.

3. Control water in a timely manner.

Generally speaking, 10-15 days before harvesting, proper water control is conducive to the improvement of sugar content. The fruit can be harvested at the right time to ensure that the sugar content is moderate. Generally speaking, except for special needs, the fruit should be harvested at nine ripeness, when the sugar content is high, the appearance is beautiful, the flavor is good, and there is a certain ability to withstand transportation.

Peaches are a very common fruit for us, and our country is also the origin of peaches, with many peach tree species. What fertilizer is good for sweetening peaches during cultivation? When the sweetness of peaches is reached, commerciality can rise.

1. Light: The coloring of peaches is directly proportional to the light, the better the light, the better the coloring.

2. Influence of temperature and humidity: peach coloring is inversely proportional to temperature and humidity, high humidity is not conducive to coloring, high temperature is not conducive to coloring, and large temperature difference between day and night is good coloring and high sweetness.

3. Influence of nutrient elements: peach tree coloring and nutrient supply have a lot of relationships, what fertilizer is good for peach sweetening, peach tree germination and young fruit stage need to use Fujinmen balanced water-soluble fertilizer to balance nutrition. Phosphorus and potassium fertilizer is needed in the middle stage, high potassium fertilizer is needed in the fruit expansion stage, the fruit expansion speed is fast, the sweetening, the peel coloring is good, the whole process needs the participation of trace elements such as calcium, boron and zinc, and the lack of medium and trace elements fruit expansion and coloring will be affected.

4. Soil influence: peach trees are shallow root fruit trees, absorbing roots are generally within 40 cm of soil layer, and the soil for planting peach trees requires good air permeability to be conducive to the healthy growth of peach tree roots.

5. Pruning impact: Improper pruning of fruit trees, shade in the middle and too dense branches will affect the light and color of peaches.

What fertilizer is good for peach sweetening, if you want to grow peaches with high sweetness, you need to strengthen cultivation management, and it is very important to improve the level of fertilization.

Most of us here use the method of deep compound fertilizer, which can maximize the utilization rate of fertilizer and minimize the waste of fertilizer. Deep topdressing, after covering the soil, the utilization rate of fertilizer is very high, and there is almost no waste. At this time, topdressing can speed up the development of the embryo, promote the hardening of the kernel, and at the same time have a significant promoting effect on the new slightly aging, fruit expansion, and flower bud development, so the peach bag has entered a closed environment after the application.

<> so that photosynthesis cannot be carried out, and the flavor will become weaker, in the words of consumers, there will be no peach flavor. The most important thing is that because the peaches are in a confined space, the evaporation of peaches is reduced, so when bagging, the bag must be opened first, and then the peaches are slowly put into the paper bag from the bottom. In this process, once the peach is damaged, it is likely to affect its fruit, and it will also affect the yield in the future.

Fruit and vegetable fertilizer fertilization generally chooses to use 45% nitrogen, phosphorus and potassium controlled-release fertilizer + biological organic fertilizer + water according to the ratio, each fruit tree needs to dig several fertilization ditches to apply, do not apply fertilizer too shallow, too concentrated in one place, to prevent volatilization, loss, and root burning. Dig a radial ditch 8 10 cm deep, each fruit tree needs to dig 6 fertilization ditches to apply, do not apply fertilizer too shallowly, too concentrated in one place, to prevent volatilization, loss, root burning, after the bag, then apply fertilizer, do not because of soil drought, drag back after the bag will enter the growth period.

After entering the growth period, we need to apply top dressing in the hard core period, which is generally in early to mid-June. At this time, top dressing can promote embryo and nuclear development, flower bud differentiation and fruit expansion, but also for the next year's fruit to lay the foundation, the fertilization is better, autumn gold winter silver summer fertilization broken copper and iron, if summer fertilization, should be in the peach tree before flowering, half a month to apply ammonium nitrate calcium, so that the tree nutrients are not easy to lose, will not shine into the weakening of the tree! If it's summer, I recommend using water-soluble.

You can add poly Wuba super potassium calcium magnesium water-soluble fertilizer to peaches, this fertilizer can improve the hardness of the fruit, keep it fresh, usually pay attention to the field management of peaches, regular watering and fertilization.

Top dressing at the fruit expansion stage of peach trees, mainly nitrogen fertilizer, combined with potassium fertilizer application, can improve fruit yield and quality. Foliar spray colorist dilution 1000 1500 times liquid to improve sweetness, speed up fruit expansion, promote early ripening, improve fruit firmness, prolong storage and preservation, and reduce physiological diseases such as soft fruits, cracked fruits, and yellow leaves.

Top dressing before germination. Top dressing in the early stage of germination is mainly to promote the growth of roots and new shoots. It lays a solid foundation for the flowering and pollination of fruit trees, and mainly uses special fertilizer for rooting promotion and balanced water-soluble fertilizer.

Reasonably increase the amount of organic fertilizer, reasonably regulate the application level of nitrogen, phosphorus and potassium fertilizer according to soil fertility and early, medium and late maturing varieties and yield levels, and the fertilizer demand of early-maturing varieties is 20% 30% less than that of late-maturing varieties; Pay attention to the combined application of calcium, magnesium, boron, zinc or copper fertilizers; Fertilizer distribution should be based on autumn base fertilizer one month after peach fruit picking, and the key period of top dressing is before and after the peach fruit expansion period.

Peaches are enlarged twice before ripening, peaches are about to ripen, if you want good fruits, we must first let the peach tree have enough nutrients, peaches are ripe before the second expansion, hidden nucleus we can apply fast-acting nitrogen, phosphorus, potassium fruit trees special compound fertilizer, mainly potassium fertilizer peaches want to grow fast, potassium fertilizer is naturally indispensable, the early fertilization is basically based on nitrogen fertilizer, not for the growth of leaves or for the rapid growth of trees, so the basic stove in the bottom fertilizer is a fertilizer with relatively high nitrogen content, now at this stage, peaches to grow, In the later stage, it should be painted quickly.

Peach tree in the expansion period is a very critical period, this period directly affects the yield and quality of peach fruit, so management is particularly important, there is a lot of work to be done in this period, the work done in this period is mainly to regulate the contradiction between vegetative growth and reproductive growth Orchards with a lack of trace elements can also be supplemented by foliar spraying, calcium deficiency can be sprayed with commercial chelated calcium solution on the foliar surface of peach trees in the early stage of growth, sprayed 2 times, 3 5 weeks after flowering, 8 10 weeks before fruit picking spray 0 3% 0 5% Amino acid calcium can prevent and treat calcium deficiency in fruits;

Peach tree in the expansion period is a very critical period, this period directly affects the yield and quality of peach fruit, the cover of the reed to manage is particularly important, this period needs to do a lot of work, the work done in this period is mainly to regulate the contradiction between vegetative growth and reproductive growth Orchards with a lack of trace elements can also be supplemented by foliar spraying, calcium deficiency can be sprayed on the foliar surface of peach trees in the early stage of growth with commercial chelated calcium solution, sprayed 2 times, 3 5 weeks after flowering, 8 10 weeks before fruit picking spray 0 3% 0 5% Amino acid calcium can prevent and treat calcium deficiency in fruits;

I feel that this is not a very certain standard, but also to consider the length of the new and the size of the load to consider comprehensively! If the tree is more vigorous, the rising strip is relatively serious, you can consider nitrogen control or even no nitrogen application facilities peach tree has entered the fruit expansion period, this period with the outside temperature continues to rise, the temperature in the shed also increases, the activity of soil microorganisms increases, the nutrients that can be absorbed by the root system are also increasing, and the humidity in the shed is relatively high, it is easy to cause the growth of peach trees.

Entering the hard-core stage, the amount of potassium and phosphorus required is very large, and the expansion period is basically synchronized, so it is necessary to consider the relationship between the hard-core period and the expansion period of water and fertilizer and the reasonable ratio of nitrogen, phosphorus, potassium and calcium. It is good to use compound fertilizer during the expansion period of early-maturing peaches.

Before the peach matures, the second expansion should be supplemented with nutrients in time, and the fast-acting nitrogen, phosphorus, and potassium special compound fertilizer for fruit trees with jujube belts should be applied, with potassium fertilizer as the main fertilizer, and the appropriate amount of topdressing outside the roots should be applied in a timely manner.

In addition to the nitrogen, phosphorus and potassium required for the growth of peach trees, calcium, magnesium, zinc and other trace elements are also added, which can effectively improve the quality of peach tree fruits, improve color and sweeten. After choosing the fertilizer, it is necessary to fertilize according to the growth of the peach tree, not that the more fertilizer, the better the effect, so we must do a good job in fertilizer and water management during this period.

Compound fertilizers should be chased. This fertilizer has a relatively high nutritional value and will increase the yield of peaches.

1.Base fertilizer: Generally speaking, it can be applied when the peach tree is decided, or after the peach is picked, you can apply the base fertilizer, mainly nitrogen fertilizer, you can apply it according to the growth of the peach tree, but do not get too close to the tree when fertilizing, so as not to cause root burning.

2.Promote flower fertilizer: in the spring flowering time mainly apply nitrogen fertilizer, and then can be carried out with water irrigation, an acre of land can be used nitrogen fertilizer, about 5 kilograms, if you use urea can also, but according to their own situation, if the amount of base fertilizer is relatively sufficient, you can reduce the amount of flower fertilizer.

After the peaches are picked, they need to be fertilized. Of course, phosphorus and potassium fertilizers are the best. Improve the wintering ability of peach trees.

There is no need to add fertilizer after the peach is picked, because the peach tree is fruiting every year, and the peach tree basically does not have high nutrient requirements after peach picking.

If you want peaches sweet, top dressing can do this.

1. Top dressing before flowering.

It is mostly used before flowering in early spring to promote budding and promote the growth of new shoots. To reduce flower and fruit drop, the fertilization was mainly balanced water-soluble fertilizer with high-nitrogen and high-potassium water-soluble fertilizer with fertile leaves.

2. Top dressing after flowering.

It is mostly applied between flowering and fruit kernel hardening, and topdressing after flowering can improve the fruit setting rate, improve the nutrition of the tree, and promote the rapid growth of the early stage of the fruit.

3. Top dressing for fruit enlargement.

It is applied after the fruit enters the rapid growth period again, and the top dressing is mainly high-potassium water-soluble fertilizer, which expands the fruit quickly and improves the sweetness and quality of peaches.

Manager Wang of Nantong, Jiangsu Province consulted on the Internet last year what fertilizer to use for peach trees, saying that his yellow peaches are not well colored, and many peaches are relatively small, and local technicians said that it is a problem with fertilizer. Through continuous comparison, I feel that the effect of Juwuba super potassium calcium magnesium water-soluble fertilizer is still relatively good, and many farmers have said that the effect is good, cost-effective, and the effect of continuous use is better. After the recommendation of the manufacturer's technical personnel, Manager Wang sent super potassium calcium and magnesium water-soluble fertilizer from our manufacturer, and planned to compare.

Look at this is the use of super potassium calcium magnesium water-soluble fertilizer**, the fruit expansion effect is more obvious, and the peach color is bright, and the sweetness is higher.

Apply more organic fertilizer, and apply potassium fertilizer once a month before the peach is ripe, which can significantly improve the sugar content and coloring. Now at this time, the effect of topdressing water-soluble fertilizer is the best, low residue, high utilization rate, high absorption is applicable, and it can be absorbed and used by plants in a week. Root topdressing and foliar spray work best together.

At this time, you can spray potassium dihydrogen phosphate on the foliar surface, a bucket of water 50 is mainly a matter of variety. Secondly, you can add a little phosphorus and potassium fertilizer.

<> fertility is too strong, or the fertilizer effect is too strong, it is not good for the growth of peach tree seedlings. It is likely to cause the phenomenon of burning roots, once the seedlings appear to burn the seedlings, hurt the roots, it is almost the end of death, or it will grow more slowly, "can't keep up with others", even if the biological organic fertilizer can. Because the newly planted seedlings have no fruiting task, nitrogen, phosphorus and potassium fertilizers should not be used as much as possible, which is easy to cause undesirable results such as overgrowth, rapid growth, and insufficient lignification.

When picking some crops under the tree, it is necessary to fertilize the crops, and the fertilizer applied to the crops can also be absorbed by the peach tree, and there is no need to fertilize the newly planted tree. What kind of fertilizer to apply: When interplanting crops, it is best to use a farmhouse fertilizer for Juwuba to promote rooting special water-soluble fertilizer containing humic acid, which can effectively improve the peach tree with more roots, living roots and strong seedlings, improve the drought resistance, cold resistance and disease resistance of peach trees, improve the absorption and utilization rate of fertilizer, improve the soil, and effectively solve the problem of peach trees not rooting, rooting, cold roots, and rotten roots.

The peach trees planted in the current year should be carried out by the method of promoting post-control. It is to promote the growth of spring shoots and expand the canopy, and the faster they grow, the better. However, sustained and rapid growth is certainly not conducive to the first physiological differentiation of flower buds, which will affect the flowering and fruiting of next year.

Therefore, it is necessary to timely and appropriately control the fertilization of 1 kg in January, and the absorption is not complete, and the trees that do not grow are 2o away from the roots, so as not to burn the roots. As for urea sprays, they are all cost-effective. But it is difficult to use, it is not good to burn roots and leaves, it is recommended not to use it.

Apply organic fertilizer around October.
