How to plant Ogan large cherries? The cultivation technique is worth trying

Large cherries have a very short growth cycle. To grow premium quality, high yield,long storage lifelarge cherries, you need the best cultivation techniques, a series of measures, the best root system. In the Ogan large cherry cultivation technique,root drenching and trunk coating are essential measures for growing high-quality, high-yield large cherries。The Ogan large cherry cultivation technique has been applied over many years, in many regions and with many varieties. Large cherries grown with the Ogan cultivation technique have the highest yield and the best quality among the same variety locally (aroma,firmness,extended storage life, colouring, skin gloss). Using the Ogan large cherry cultivation technique, you can also grow organic large cherries and selenium-enriched large cherries.

Key points of the Ogan large cherry cultivation technique:

1) Standard cultivation: after harvest, control shoots and strengthen flower buds; around the flowering period, strengthen flowers and set fruit; after fruit set, supplement fertiliser in time to increase yield and improve quality.

2) When hormones are needed, reduce the side effects of hormones.

3) Special cultivation: for difficult fruit set, premium large cherries and selenium-enriched large cherry production, contact the Ogan company directly.

Method of use:

1. Root drenching or drip irrigation: 3-4 times (once after harvest, once before flowering, once at the young fruit stage, and once at the second swelling stage for mid-to-late ripening varieties).

Formula: Ruibaier + water-soluble fertiliser.

2. Foliar spraying: Ogan/Puoule, use 4-6 times (2 times after harvest, 2 times before flowering, 2 times after flowering)

3. Trunk coating: apply Ogan/Puoule to the trunk or spray the tree once during the spring bud-break period.

Timing of use:

I) Standard cultivation: after harvest, control shoots and strengthen flower buds; around the flowering period, strengthen flowers and set fruit; after fruit set, supplement fertiliser in time to increase yield and improve quality.

1st time: about 1 week after harvest, spray once with Ogan + balanced fertiliser; drench the roots or drip irrigate with Ruibaier + water-soluble fertiliser.

A. Vigorous trees: use Ogan at 200 times, to control shoots and strengthen flower buds; drench the roots with high-phosphorus high-potassium fertiliser + Ruibaier, and appropriately increase organic fertiliser.

B. Moderately vigorous trees: use Ogan/400 times, to maintain shoots and strengthen flower buds; drench the roots with balanced fertiliser + Ruibaier.

C. Weak trees: use Ogan/300 times, to maintain shoots and strengthen flower buds; drench the roots with balanced fertiliser + Ruibaier.

2nd time、On the 7th day after the 1st use, apply Ogan/at 300 times as a foliar spray once。

3rd time、In spring, at the pink bud stage to before flowering, use Ogan/200 times as a foliar spray once。Drench the roots or drip irrigate once with Ruibaier + balanced fertiliser or high-nitrogen water-soluble fertiliser.Apply Ogan/Puoule zinc to the trunk or spray the trunk once (spray Ogan/Puoule zinc at 200 times or coat dry branches at 50 times).

4th time、When 80% of flowers have fallen, spray once with Ogan at 300 times + Ogan boron.

5th time, 4th timeOn the 7th day after use, apply Ogan/at 300 times as a foliar spray once。If you follow ourmethod for flowerand fruit retention, the effect is especially good, and the fruit load increases by 20-30% compared with last year. At this point you must drench the roots or drip irrigate once with Ruibaier + high-potassium balanced fertiliser,

6th time: at the second swelling stage, spray once with Ogan at 300 times + high-potassium fertiliser + Ogan calcium.For mid-to-late ripening varieties, drench the roots once with Ruibaier + high-potassium fertiliser.

1st time -2nd time is to protect autumn shoots and strengthen flower buds; 3rd-5th times are to strengthen flowers and set fruit; 6th time is to increase the large cherry'scolouring andskin gloss.

Most large cherry growers can meet their requirements using this method. It can be said that the large cherries of the same variety locally have the best quality. Below is a case of standard cultivation.

In 2016, at the China Cherry Annual Meeting's quality large cherry judging competition, the Qinghai Ledu Ogan Demonstration Orchard, for the first time

after using the Ogan technique, won third prize with both varieties Rainier and Sunburst

Note:The Qinghai Ledu Ogan Demonstration Orchard only used our large cherry cultivation technique on part of the orchard in the first year, and still took 3rd place. If the technique were used throughout the whole process, the quality could be even better! With continuous use, the effect will also be better next year!

II) When hormones are needed, reduce the side effects of hormones.

It can be mixed with hormones (1 time for fruit retention, 1-2 times for swelling). Ogan at 300 times + hormone; dilute the hormone to the maximum ratio so that you get the effect of the hormone without its side effects.

III) The plan for growing the highest-quality large cherries.

1st time: about 1 week after harvest, spray once with Ogan + balanced fertiliser, and drench the roots or drip irrigate once with Ruibaier + water-soluble fertiliser.

A. Vigorous trees: control shoots and strengthen flower buds, spray Ogan at 200 times，Drench the roots with high-phosphorus high-potassium fertiliser + Ruibaier, and increase organic fertiliser.

B. Moderately vigorous trees: maintain shoots and strengthen flower buds, use Ogan at 400 times, drench the roots with high-phosphorus high-potassium fertiliser + Ruibaier, and increase organic fertiliser.

C. Weak trees: promote shoots and strengthen flower buds, use Ogan at 400 times, drench the roots with high-phosphorus high-potassium fertiliser + Ruibaier, and increase organic fertiliser.

2nd time、On the 7th day after the 1st use, apply Ogan/at 300 times as a foliar spray once。

3rd time、In spring, at the pink bud stage to before flowering, spray once with Ogan at 400 times and Puoule zinc at 400 times.Drench the roots once with Ruibaier + balanced fertiliser or high-nitrogen water-soluble fertiliser. Apply Ogan/Puoule zinc to the trunk or spray the trunk once (spray Ogan at 200 times + Puoule zinc at 200 times or coat dry branches at 50 times)

4th time: when the petals begin to fall, spray once with Ogan at 400 times and Puoule boron at 400 times.

5th time: on the 7th day after the 4th use, spray once with Ogan at 400 times and Puoule boron at 400 times.If you follow our method for flower and fruit retention, the effect is especially good, and the fruit load increases by 20-30% compared with last year. At this point you must drench the roots once with Ruibaier + high-potassium balanced fertiliser,

6th time: at the first swelling stage, useOgan/400 times and Puoule boron at 400 times as a foliar spray once。For mid-to-late ripening varieties, drench the roots once with Ruibaier + balanced high-potassium fertiliser.

7th time: at the second swelling stage, useOgan/400 times and Puoule calcium at 400 times as a foliar spray once

Effects of use:

1. Roots: thick main roots, many fibrous roots, good nutrient absorption.

2. Stems: thick and sturdy stems, short internodes.

3. Leaves: dark green leaf colour, thicker leaves, increased photosynthesis.

4. Flowers: strong flowers, plump pollen, long flowering period, improved fruit set rate.

5. Fruit: uniform fruit size and colouring, sugar content and all indicators increased year on year, taste noticeably improved. Hongdeng large cherries grown with the Ogan large cherry cultivation technique weigh 7-10 g per fruit, have a sugar content above 17, and a rich large cherry flavour. Other large cherry orchards locally struggle to exceed a sugar content of 15.

6. Branches: can control the large cherry'sexcessive branch growth,no pruning or less pruning ofbranches, less consumption of the tree's nutrients, making the branchesthick and sturdy, with abundant nutrition，In winter, effective, plumpflower buds can form.

** The indicators here are only relative indicators, not absolute indicators. The data reflect an overall improvement in quality indicators. The region providing the indicators is where large cherries are grown on saline-alkali land. If large cherries were grown with the Ogan technique in an optimal growing area, the overall indicators would be even better. Using the Ogan cultivation technique, the total sugar of greenhouse large cherries can reach 23.
