After picking blueberries, do you top dressing first, or do you cut them first?

At this stage, many regional open-field blueberries are coming to an end. The post-harvest management of blueberries mainly includes post-harvest pruning, fruit picking fertilizer, pest control, and flower control.

In fact, there is no hard and fast rule on the order of pruning and fruit picking, and it mainly depends on the early and late period of fruit picking.

Generally, if the fruit picking ends early, it is recommended to prune in time and then apply fruit fertilizer, if the fruit picking ends very late, you can fertilize first and then prune.

Key technical points: post-harvest pruning, if you want the new branches to bloom and bear fruit next year, you must have enough time (July-September) for it to grow fully, and the fertilizer and water conditions at this stage should be good, and the branches should have a high degree of maturity.

The plants are too tall and re-pruned after harvest.

After picking blueberries, do you top dressing first, or do you cut them first?

A: My personal advice is to prune first and then top dressing, which is conducive to the growth of blueberries.

I think blueberries should be pruned and then fertilized to reduce nutrient loss and waste in the trees.

Then fertilize again, because fertilization after pruning can effectively promote the fruit tree to extract new shoots and new branches.

After picking blueberries, you should first prune the diseased branches to reduce the damage of pests and diseases, and then fertilize to take care of the stable and abundant yield of blueberries.

After picking the fruit, it is necessary to prune the branches first and then fertilize, as long as the fruit tree is fertilized after picking the fruit, so that the fruit tree should not be mistaken to bear fruit in the next year.

After watching the blueberries, whether to top dressing or fat loss first, you can also lose fat after dropping blueberry top dressing.

When playing with blueberries, you should first prune a branch and then top dressing. It does not affect fertilizer loss.

After picking blueberries, pruning is done first and then top dressing.

After picking blueberries, you should first cut the technique, and then top dressing improper growth.

Types, methods, periods and dosages of blueberry fertilization.

Variety: The application of complete fertilizer increases the yield by 40% compared to the single fertilizer. Therefore, the ratio of nitrogen, phosphorus and potassium is advocated in blueberry fertilization.

The fertilizer ratio mostly tends to be 1 1 1. In the soil with high organic matter content, the amount of nitrogen fertilizer was reduced, and the ratio of nitrogen, phosphorus and potassium should be 1 2 3. On mineral soils, the phosphorus and potassium content is high, and the ratio of nitrogen, phosphorus and potassium should be 1 1 1 or 2 1 1. Blueberries are not only less susceptible to nitrate nitrogen, but nitrate nitrogen also causes damage such as poor growth of blueberries.

Therefore, it is better to apply ammonium nitrogen fertilizer such as ammonium sulfate to blueberries. Ammonium sulfate also has the effect of lowering the pH value of the soil, especially on sandy and calcareous soils with high pH values. In addition, blueberries are very sensitive to chlorine and can easily cause excessive poisoning, so do not choose chlorine-containing fertilizers such as ammonium chloride and potassium chloride when choosing fertilizer types.

Method and period: highbush blueberry and rabbit eye blueberry can be applied in furrows, and the depth should be 10 15cm. After the dwarf bush blueberries are planted, they are connected into patches, and they are mainly sprinkled. Soil fertilization is generally carried out in early spring before budding, and can be applied in 2 times, and 1 more time at the berry ripening stage.

Fertilizer application: Excessive fertilization of blueberries can easily cause tree damage or even the death of the whole plant. Therefore, the amount of fertilization should be determined carefully, depending on soil fertility and the nutritional status of the tree.

In the blueberry producing regions of the United States, leaf analysis techniques and soil analysis techniques are widely used in production. According to the results of production tests and years of research, the leaf analysis standard values of highbush blueberry and rabbit eye blueberry were formulated, so as to avoid the blindness of fertilization.

I've been using 2-amine sulfate 8 times a year

Flowering, fruiting, germination, and root nourishment can be fertilized.

Now it's time to fertilize once! Before flowering!

There is a technical post at the top of the bar, you can go in and have a look! How to water, how to fertilize!

I don't understand, I don't fertilize every month!

Fertilization: Organic fertilizer is recommended. The excessive use of chemical fertilizers in China's farmland has caused serious pollution, and eventually the land yield has been reduced or even extinct.

Type of fertilization. The application of nitrogen, phosphorus and potassium compound fertilizer mixed organic fertilizer has a better effect than that of single fertilizer; The ratio of nitrogen, phosphorus and potassium fertilizer should be 1 1 1; It is better to apply ammonium nitrogen fertilizer such as ammonium sulfate, and nitrate nitrogen fertilizer should not be applied; Blueberries are sensitive to chlorine, so do not use chlorine-containing fertilizers such as ammonium chloride and potassium chloride.

Fertilization method and period. Tall bushes and rabbit eye blueberries can be cast in furrows, and the depth is 10 to 15 cm. Fertilization is done in early spring before bud break, but it can also be applied again once during the ripening of berries.

Amount of fertilizer. Excessive fertilization can easily cause damage to the blueberry tree or even the death of the whole plant, so the amount of fertilizer should be determined very carefully, and it must be determined according to the soil fertility and the nutritional status of the tree.

Do you plant on a large scale, or do you plant a few for ornamentation?

1. Fertilization principle: the requirements of various nutrients for blueberry growth and fruiting should be fully met, organic fertilizer should be applied, and the use of chlorine-containing fertilizers and chicken manure should be prohibited.

2. Fertilizer types: Commonly used fertilizer types include biogas slurry fertilizer, green manure, cake fertilizer, compost, manure and manure and other organic fertilizers.

3. Fertilization of young trees: apply fertilizer once in March and May after planting, apply 300 500g of organic fertilizer or 30 50g of potassium sulfate compound fertilizer, fertilize at 15 30cm from the roots of the tree in the first year after planting, and fertilize at 30 50cm from the roots of the tree in the second auspicious year after planting.

4. Fertilization of fruiting trees: apply basal fertilizer once a year to fruiting trees, and apply 5kg of well-rotted cow dung, manure and other organic fertilizers before germination from mid-September to February of the following year; If 1 top dressing is used, it can be applied within 1 to 2 weeks after flowering; If 2 times of top dressing are used, they can be applied at the end of the flowering and harvesting period, and the plant is applied potassium sulfate Shenlu compound fertilizer (nitrogen: phosphorus:

Potassium is 15:15:15) 150 300g.

Summary. Blueberry summer fertilization Hello, pro 1Top dressing is mainly fertilized by drip irrigation, which can be fertilized with watering in several periods such as germination, fruit expansion and fruit picking.

The fertilizer raw materials used in drip irrigation fertilizer must have high solubility and low impurity content. The products of the carbon replenishment series are on the line. When mixing fertilizers, pay attention to the matching of fertilizers to prevent precipitation, and the trace elements should be in chelated state.

2.Extra-root topdressing refers to spraying fertilizer on the tree body, specifically should pay attention to the two periods before defoliation and before germination, urea before defoliation, and zinc before germination. Nitrogen fertilizer and boron fertilizer were sprayed at the flowering stage, calcium was supplemented after fruit set, and phosphorus and potassium fertilizer were mainly sprayed at the fruit expansion stage.

Foliar fertilizer should be sprayed in the morning or afternoon on a cloudy or sunny day with a temperature of 18 to 25 years, with the leaves on the front and back.

Types of fertilizers used for blueberries in summer.

Types of fertilizers used for blueberries in summer Hello, pro "Compared with organic fertilizers, blueberries are more suitable for organic fertilizers with complete nutrients, rich microorganisms and low salinity. Such as: fermented chicken manure, pig manure, cow manure, all kinds of cake fertilizer, bone meal and other organic fertilizers. ”

Shouldn't blueberries be water-soluble fertilizers in summer?

Blueberries are more suitable for organic fertilizers that are nutritionally complete, rich in microorganisms, and low in salt.

Blueberries are fertilized during the summer nutrition growth period.

The use of water-soluble fertilizer on blueberries Strictly speaking, the fertilization of blueberry fruit trees depends on the blueberry tree variety, blueberries have high bush blueberries, rabbit eye blueberries and dwarf blueberries, among which high bush and rabbit eye varieties can be applied the same balanced water-soluble fertilizer, dwarf bush blueberries need to apply high nitrogen and potassium water-soluble fertilizer, as follows: (1) high bush, rabbit eye, the flower fruit general water-soluble fertilizer formula, the amount per mu is 5 kg, mixed with water 800-1000 kg, fully dissolved after the root is evenly applied. It is usually done every 10-15 days.

High bush, rabbit eye topdressing water-soluble fertilizer (2) dwarf bush, dwarf bush blueberry fertilization in the berry ripening period topdressing high nitrogen and potassium water-soluble fertilizer, the same is an acre of land 5 kg with water 1000kg fully dissolved and stirred, the root flushing.

Blueberry summer slightly nutritious growth period with fertilizer Hello, dear. Compared with chemical fertilizers, blueberries are more suitable for organic fertilizers with complete nutrients, rich microorganisms and low salinity, such as: fermented chicken manure, pig manure, cow manure, various cake fertilizers, bone meal and other organic fertilizers, which are milder and have a longer fertilizer effect.
