Grapes

Common problems and solutions in the later management of sunshine roses for reference!

 

 

The "Sunshine Rose" grape is both beautiful and delicious, as well as nutritious and safe. It is not an exaggeration to say that it is an aristocratic variety in the grape world. However, it is not easy to grow high-quality Sunshine Rose grapes. The price difference between high-quality and ordinary sunshine roses is also very different, and the price difference per catty can reach 100 yuan.

Sunshine Rose has high requirements on soil environment, yield control and management techniques. The characteristics and labels of high-quality sunshine roses are large fruit, crisp flesh, high sugar, and strong fragrance.

 

 

"They are all managed in the same way. Why are your grapes so much bigger than mine?", "Because my fertilizer uses 'sampan cichlid protein', you don't!"

This time, I will take you to the demonstration field of cichlid protein grapes in Lianyungang, Jiangsu Province. How is the growth of the sunshine rose grown on cichlid protein?

 

 

From the perspective of overall growth, the plants after using cichlid protein are more robust, with thicker branches, higher lignification, and darker green leaves. The branches of the plants in the control group were thinner, and the upper leaves were yellowish and more tender.

 

 

Judging from the comparison of fruit bunches, the color of Sunshine Rose Hips using cichlid protein is more emerald green and shiny, giving people a very spiritual feeling. On the other hand, the cluster shape is still relatively loose, and the color of the fruit is not green enough, which looks listless.

Looking closely at the fruit, the contrast is more obvious. The Sunshine Rosehips using cichlid protein are larger, the gaps are basically filled, the string shape is better, and the fruit dents are obvious, indicating that the late expansion potential is great. In contrast, the fruit grains of the control were smaller, the gaps were larger, the string shape was poor, and the dents of the fruit grains were shallower.

 

 

When the environment, nutritional stress or suffering from diseases and insect pests, the grape leaves are dark green, plump, stretched, fresh and luxuriant after using cichlid protein. The unused grape leaves of the control group tended to wither, yellow and fall off, and lost their functionality, so that the supply of organic nutrients was out of balance, and the vigor of the trees declined rapidly.

 

 

The aroma of sunshine rose is also one of the main factors that determine the selling price. Its aroma comes from alcohols, olefins and a few aldehydes. These aromatic substances are all secondary metabolites in the fruit. The synthetic precursors are Substances such as carbohydrates, fatty acids, and a large amount of amino acids are bound by glycosides after formation, and the fragrance cannot be exerted. Only under the action of esterase can the aromatic substances be synthesized and released. Studies have shown that the formation of enzymes requires a large number of amino acids. Cichlid protein is rich in amino acids, small molecule peptides, calcium and other active organic substances.

 

Want to grow high quality, high priced Sunshine Roses

You can do the following

 

 

Soil is the root of grape growth and the basis for producing high-quality fruit. When the soil has low organic matter content and low nutritional level of fruit trees, it is difficult for the fruit to produce aroma. The soil organic matter for high-quality sunshine roses must reach more than 3%, preferably 8%. Japan's standard is 6-8%, the highest place is 15%.

Cichlid protein can make beneficial microorganisms in the soil multiply rapidly with fish protein and other organic substances as carriers, and the activity can be increased by more than ten times, so that the soil structure is optimized, and the ability to retain fertilizer and water is significantly improved. If used continuously, the soil becomes loose and fertile, improving soil ecology and increasing soil fertility.

 

 

Because sunshine rose seedlings are born with viruses, which have a great impact on growth potential and fruit quality, in the process of planting sunshine roses, the main goal should be to cultivate strong trees.

Cichlid protein can provide organic high-protein combined nutrition for grape vines, ensure good absorption of trees, well-developed root system, and good conversion of photosynthesis in leaves, thereby improving the stress resistance of Sunshine Rose.

 

 

Ensuring the supply of organic matter and calcium to ensure the quality of root growth and the activity of leaves in the later stage is an effective means to enhance the richness of fruit fragrance.

Cichlid protein is rich in organic nitrogen, which can promote the synthesis of chlorophyll in the leaves, so that the leaves are dark green and shiny. At the same time, it can promote the balanced absorption of various nutrients needed by crops, so as to prevent the symptoms of yellowing leaves caused by certain nutrient deficiencies.

 

In continuous high temperature weather, mature fruit ears are not covered by leaves, and the fruit will suffer from severe sunburn (air burn) when the fruit is directly exposed to light; Sunshine roses are prone to pericarp browning at the late stage of maturity, commonly known as "fruit rust". Days, fruit sugar content began to occur around 17%, and with the increase of fruit sugar content, fruit rust aggravated.

(1) Increase the calcium content in the peel and control excessive nitrogen fertilization

(2) Expand the canopy area;

(3) Reduce the burden of fruit setting;

(4) Avoid direct sunlight and put on colored bags (green, blue) to reduce the yellowing of the peel.

(5) Sell in time, because although mature fruits can hang on trees for more than a month without reducing sugar and not softening, the longer the fruit hangs, the more serious the rust will be.
