Key techniques for promoting coloration of cherries in greenhouses
Spraying fruit-surface film-free bagging agent: spraying it on the fruit surface acts like bagging, does not affect fruit respiration, and can also prevent fruit russeting and fruit cracking, improve fruit-surface coloration and glossiness, reduce pesticide residues and improve quality. Foliar spraying of Xin Gao Zhi Mo (new high-fat film) can prevent leaves from viral infection, make branches and leaves lush and green, and enhance the accumulation and directional transport of photosynthesis products...

Never relax management after harvesting large cherries
Large cherries in Shaanxi are basically harvested by May-June, and management is often relaxed after harvest. You should know that it is precisely after harvest that the effective period of cherry flower bud differentiation occurs. Balanced and timely nutrient supply to the tree plays a very important role in restoring tree vigor and forming flower buds. In the main cherry production areas of Baqiao in Xi'an and Tongchuan, growers all have rich experience...

How to manage large cherries in autumn? Focus on these two key points
1. Cultivation of compact fruiting branch groups. When the space where a branch is located is relatively small or the branch is on the back of a main branch, it should be cultivated into a compact small fruiting branch group. Cultivation method: for branches on the upper part of the main branch and on its back, twist the shoots during the growing season or pinch the tips repeatedly and then let them grow untrained; for branches not treated during the growing season, during the dormant period, cut them very severely short...

Autumn basal fertilization for sweet cherries is timely now, and fruit growers should not miss it
When it comes to the key points of autumn basal fertilization, the first thing to emphasize is "early." It is generally carried out in September-October, but early application in September gives the best results. This is because during this period the soil temperature is relatively high, the roots absorb fertilizer over a longer time, and the absorption rate is also fast. Once the fertilization timing is grasped, the application rate must also be increased...

How to manage sweet cherries in summer? These ten techniques must be mastered
1. Soil, fertilizer and water management. The fruit development period of sweet cherries is short, requiring concentrated nutrients. Pay attention to topdressing before flowering, during fruit development, after harvest and in autumn. The first application is mainly nitrogen fertilizer combined with phosphate and potassium fertilizer; the second is mainly phosphate and potassium fertilizer; after harvest, compound fertilizer is mainly used. Decomposed human manure and urine, decomposed soybean cake water, etc. can also be applied (farmyard manure...

How to manage greenhouse cherries well through the summer?
I. Cultivation pitfalls. In areas such as Guanzhong and Tongchuan in Shaanxi, there are some pitfalls in large cherry cultivation, mainly as follows: 1. Deep application of base fertilizer. Cherry roots are relatively shallow, and applying base fertilizer by digging trenches between rows or between plants easily damages the roots and leads to a large occurrence of Chinese cherry and ZY-1 rootstock seedlings; in addition, if the base fertilizer is not fully decomposed...

How to promote flowering in sweet cherries? Master these four measures
1. Spray paclobutrazol. To ensure there are enough flower buds every year, first, from mid-June to early July, spray the canopy with a 500-1000 mg/kg paclobutrazol solution, once every 10-15 days, for 1-3 consecutive sprays, to inhibit vegetative growth (spray 1-2 times for trees of moderate vigor and 2-3 times for vigorously growing trees, until the canopy branches basically stop growing), and promote flower bud differentiation.

Do not relax post-harvest management of cherries; grower friends should take it seriously
I. Focus on summer pruning. While removing the film, promptly cut back the canopy and carry out heavy pruning. 1. Cut back the canopy. This method can reduce the overall height of each cherry tree canopy by 50-80 cm respectively, preventing the tree from growing taller and taller and affecting the ventilation and light conditions inside. 2. Cut and thin the main branches. Heavy cutting is required...

What are the management methods for cherries from flowering to before ripening?
The flower and fruit management of cherries is mainly reflected in pollination and fruit retention, flower and fruit thinning, and fruit protection before harvest. Cherry is a fruit tree with low self-fruitfulness. To ensure fruit set, in addition to configuring pollinizer trees properly when establishing the orchard, artificial pollination and the use of flower-visiting insects to assist pollination should also be done well to increase the fruit-setting rate. At the same time,...

When is the best time to water sweet cherries?
What should be paid attention to when planting sweet cherry saplings? When planting sweet cherry saplings, pay attention to the following points: 1. Temperature. Sweet cherry is a fruit tree that likes warmth and is not cold-tolerant, and it is suitable for cultivation in places with an average annual temperature of 10 to 12 degrees Celsius. Abnormal temperature refers to the high and low temperatures within the suitable temperature range for sweet cherries. Generally, high...
