How can I increase the yield of grapes? Anti cracking fruit rotten fruit?

Grape anti-cracking methods and related information.

Yu Yuanji from Pujiang County, Zhejiang Province, has contracted 200 acres of vineyards by himself, and has a stable income of more than one million yuan every year. On March 26, Mr. Yu traveled thousands of miles from Zhejiang Province to Weinan City, Shaanxi Province to promote Kao****. What was the reason for him to come to Weinan thousands of miles away?

And what made him satisfied? On the morning of the 27th, Yu Yuanji told about his troubles. Although Mr. Yu contracted 200 acres of vineyards by himself, the fruits had serious fruit cracking, rotten fruits, and no nutritious fruit return during the young fruit stage to the swelling stage, which greatly reduced the yield of grapes.

In order to guarantee the yield and quality of grapes, we propose the following measures. Grapes are usually pruned two weeks after the leaves (late autumn), and the wound should be sealed with a callus antiseptic film in time after cutting to prevent freezing, dry cracking, and bacterial infection. Spray the tree body with 200 times the liquid of the tree protector general to improve the quality of hibernation.

Clearing, pruning, and removing residual branches and leaves before the spring injury can effectively reduce the reproduction of overwintering pests and diseases. Continue to spray the tree body with 200 times the liquid of the tree guard, irrigate the roots, combine weeding, fertilization, and irrigation to urge the tree to wake up early. After the flower buds appear on the grape vines, spray 500 times the new high-fat film to protect the flower buds, prevent frost (inverted spring cold), prevent natural environmental pollution (such as sandstorms), effectively control humidity and temperature indicators, and ensure the healthy growth of flower buds.

At the same time, fungicides, insecticides, and micro-fertilizers are used in combination to prevent gray mold, anthracnose, mosaic disease, downy mildew, black pox, etc., and improve the quality of leaves and flower buds. In the young fruit stage, Kao No. 3 was used to promote the transformation of top tip nutrition to the direction of fruit, and the grape Zhuangtilin dredging and channeling system was used to create good conditions for fruit development. (The dosage of chlormequat or paclobutrazol can be halved when using Kao No. 3, and the dosage of bulking hormone can be halved when using Grape Zhuangtilin) Grapes should be fertilized twice before fruiting, and bulking hormone can be added.

Around mid-April, artificial topping begins, before flowering, go to the top tip, and use Kao No. 3 to control the buds, generally the buds of the tree come late, and the buds of the weak trees come early. After the budding, paclobutrazol and borax are used. When the shoots begin to grow, the buds are cultivated by choosing one of the two.

The speed of the long tip should grow naturally, not rush, when it grows to the knot, it should hit the top tip, pick the core, and spray to promote Kao No. 3. In early May, the grapes are in bloom, and the flowers and fruits should be preserved. Pay attention when thinning the head:

Two ears are left for strong branches, one ear is left for mediocre branches, and no weak branches are left. After that, start top dressing (strong fruit fertilizer, foliar fertilizer), spray expansion fertilizer, foliar fertilizer, chasing coloring fertilizer in the expansion period, and the third spraying of Kao No. 3 will effectively solve the problems of serious fruit cracking, rotten fruit, and nutrient reflux.

Grape fissile fruit cause variety problem: grape fissile fruit mostly appears in varieties with very thin grape skins, such as emerald, Victoria's Secret and other species, so when planting grapes, you can choose varieties with good grape skin malleability and thicker grape skins.

Fruit tightness: When planting grapes, it is necessary to thin not only the flowers but also the inflorescences, and the significance of thinning the inflorescences is actually to better avoid the fruit being too close and cracking in the middle and late stages of development. The grapes grow too closely, and during the expansion period of the grapes, due to the limited indoor space for growth and development, the inner grains are extruded into the outer grains, which will cause the outer grains to crack.

Disease impact: grape diseases are more, in which downy mildew and cob brown blight will lead to grape cracking, due to these two diseases key erosion of the outer skin of the fruit, resulting in many wounds on the outer skin of the fruit, when the fruit is enlarged, this wound will become the root cause of the crack.

Unreasonable watering: when the grape fruit enters the expansion period, if the early drought rainfall is less, the rainy temperature in the middle and late period will lead to fruit cracking, the drought rainfall will directly affect the expansion of the grape fruit, in the rainy temperature due to sufficient precipitation will cause the fruit to expand rapidly, because the fruit expansion efficiency is too fast, beyond the expansion rate of the peel, it will lead to the fruit cracking.

Improper fertilization: When planting grapes, if too much basal fertilizer is applied or too much growth hormone fertilizer is applied, it can also cause the fruit to split. Applying too much basal fertilizer will cause overcapacity for grape grains to digest and absorb nutrients, and the growth and development rate of grape fruit is faster than that of the peel, and there will be fruit cracking, and the application of growth hormone fertilizer too much is the same big reason.

The first step to prevent grape cracking is to select varieties with thick skins and high skin ductility when selecting grape varieties for planting, rather than grape varieties with thin skins and low ductility. The second is to do a good job of combing the fruit, before the grapes are in full bloom, the grapes should be combed after the fruit is produced, and part of the fruit that grows too dense should be removed. To maintain a stable soil moisture content, it is necessary to irrigate immediately when there is little rainfall during drought, and to do a good job in preventing flooding during rainy seasons.

Do a good job in disease prevention, in the disease-prone period to immediately spray medicine to prevent disease, once the disease is found, the diseased grains should be pruned off, in order to prevent the healthy health of the fruit, but also according to the fruit bag to alleviate grape cracking. Calcium and zinc supplementation, timely calcium and zinc supplementation for grape function can improve the firmness of grape skin, and thickening of grape skin can reduce grape fruit cracking. The occurrence of grape fruit cracking obviously affects the quality and yield of grapes, and will make the grower's energy invested in half a year go to waste, so it is necessary to do a good job of grape fruit cracking in advance to create more profits.

The first is to ensure the fertility of the soil, and must eat pesticides in time, at the same time must remove weeds in time, and there is also to kill insects in time, and then you can also put a protective film on the outside of the grapes.

First of all, it is necessary to ensure sufficient light, secondly, we should pay attention to the appropriate temperature, timely watering and fertilization, strengthen water and fertilizer management, regularly spray pesticides, remove insect pests in time, and ensure the permeability of the soil.

It is necessary to spray pesticides regularly, and at the same time, it is also necessary to strengthen the management of water and fertilizer, timely watering and fertilization, ensure the permeability and fertility of the soil, timely loosen the soil, regularly remove insect pests, and ensure sufficient sunlight.

First of all, you can bag the grapes when they are fruiting, be sure to ensure reasonable topdressing and watering, and when the weather is too hot, you should also pay attention to sun protection, which can prevent grapes from cracking.

To prevent grape cracking, the first thing is to water the grapes less and reduce the moisture of the grapes. The second is to reduce the exposure of grapes to sunlight. The absorption can be attached to the vineyard with a layer of black netting.

You can take some preventive drugs in advance, and at the same time, you should also pay attention to scientific management skills, but also pay attention to the ripeness of grapes, and learn some grape planting techniques.

Be sure to drain the water in time, do not let the soil moisture too heavy, otherwise it will cause such a result, and must be ventilated frequently.

First of all, when planting grapes, you must choose fertile soil for planting, pay attention to the distance between grape seedlings, water more, observe its growth cycle, and then remember to spray pesticides regularly on grapes to prevent insect infestation.

1. Strengthen disease prevention and control.

After pruning in late autumn, winter and early winter, completely remove diseased leaves, diseased fruits, and dead branches, and burn them or bury them deeply. Spray 5 Baumé stone sulfur mixture before germination, and spray 25% powder rust 1500 2000 times liquid when powdery mildew occurs, or 50% antibacterial special 600 800 times solution, 1 time every 10 days, spray 2 3 times.

2. Timely summer scissors.

After summer pruning, the head guards the shelf surface is ventilated and light-transmitted, and the cut branches and leaves are transported out of the orchard for deep burial to reduce the source of fungi.

3. Reasonable load.

Improve cultivation management technology, cultivate robust trees, and control the yield through ear thinning and ear shaping, which is generally controlled at about 1500 kg per mu.

4. Bagging in time.

Generally, when the fruit is thinned and the soybean grains are large, spray 1 time before bagging, methyl tobuzin, carbendazim, etc., spray evenly, focus on spraying fruit ears, and then bag after the liquid is dried, after 8:00 a.m. 10:00 p.m. or 16:00 p.m.

5. Reasonable fertilizer and water.

In the period of rapid fruit expansion, the soil should be kept in a state of sufficient and stable moisture, and attention should be paid to timely skin drainage and water preparation, and smooth drainage and irrigation. At the same time, the physical properties of the soil were improved by deep turning and application of organic fertilizer to reduce the change of soil moisture.

With the continuous development of social economy, in real life, we will always encounter a variety of problems, especially for the problem of grape cracking, which makes many friends very puzzled, why this situation occurs, how to prevent it, and then take you to see how we can effectively prevent grape cracking.

First of all, we must know that there are many reasons for grape cracking, including calcium deficiency, so we must carry out relevant calcium supplementation treatment on the calcium-deficient land every day, and apply relevant calcium fertilizer to the soil calcium-deficient plots, which can not only effectively prevent grape cracking, but also improve the sugar content of grapes, in addition, we must also keep the soil moisture content relatively stable, when the weather is relatively dry, we must glue the vineyard to the corresponding fruit, and wait until the grapes are ripe. We also had to cover the mulch to prevent the weather from drought, and to prevent flooding, which could have a serious impact on the grapes.

Of course, in addition to the above methods, we must also be careful in the process of planting, such as in the process of planting grapes, do not plant too closely, once the recruitment is too close, then it is likely to lead to grapes in the process of growth, to rob each other of nutrients, so that the grapes will be cracked after growth, and once the phenomenon of cracked fruit, it is likely to be very serious for farmers. In addition, when the grapes are ripe, we must bag, and the bag must choose the corresponding fruit bag with better air permeability.

To sum up, we can use the above methods to prevent the phenomenon of grape cracking, only in this way can we better protect our economic and property security, and only in this way can we more likely to recover our losses.

First of all, we should water and fertilize in time, strengthen water and fertilizer management, ensure sufficient light, spray pesticides in time, remove insect pests regularly, and do a good job in ventilation and drainage.

Be sure to choose excellent grape varieties for planting, water them in time when planting, pay attention to the moisture of the soil, fertilize them in time, and add nutrients in time.

We must pay attention to the growth of grapes, the situation should be timely thinning flowers and fruits, we must pay attention to the proportion of fertilizer, and pay attention to the watering situation.

What is the reason for the rotten fruit of grapes, and why is the prevention and control effect good?

Grape rot is a phenomenon that tends to occur in the later stages of grape growth, which seriously affects the quality and yield of grapes, and causes great economic losses to farmers. What causes rotten grapes? How can it be prevented? Read on:

What causes rotten grapes?

1. Bacterial infection.

Generally, the main diseases that cause grape rot are white rot, anthracnose, and black rot also occurs in special years.

2. Malnutrition.

The tree is weak, partial nitrogen fertilizer, lack of potassium, calcium, trace elements; Excessive fruit hanging and large load lead to weak plant growth and reduced disease resistance.

3. The climate is humid.

Poor summer pruning leads to orchard canopy, poor ventilation and light transmission, excessive rainfall, and excessive relative humidity of soil and air, which accelerates the spread of diseases.

How to prevent and control grape rot.

1. Strengthen cultivation management.

Reasonable fertilization of pure nitrogen amount controlled at about 750 kg hectares, fertilizer should be applied in a timely manner, to prevent growth, to open a ditch and deep application, to achieve the combination of organic fertilizer and inorganic fertilizer, nitrogen, phosphorus, potassium fertilizer appropriate combination, to increase the application of potassium fertilizer, in order to improve the disease resistance of plants. It is best cultivated in facilities or in bags.

Timely topping, timely tying of vines During the growth period, the orchard should be well ventilated and transmitted to reduce the disease. At the same time, it is necessary to remove the secondary shoots in time to prevent the canopy from being too closed and reduce the occurrence and spread of diseases. At the same time, it is necessary to do a good job of drainage in the orchard after the rain to prevent water accumulation in the orchard.

After the grape harvest, remove the side shoots, cobs, tendrils, stiff fruits, etc. left on the plant and shelf surface in time, and completely remove the dry branches and fallen leaves that fall on the ground from the garden, and then burn them in a centralized manner.

2. Eliminate the pathogenic bacteria of overwintering.

1) After the grape harvest, remove the damaged shoots and old vines in time to enhance the permeability of the garden.

2) Combined with winter pruning, remove the secondary shoots, cobs, tendrils, stiff fruits, etc. left on the plant and shelf surface, and completely remove the dry branches and fallen leaves that fall on the ground from the garden, and then burn them intensively.

3. Pharmaceutical prevention and control.

Sprinkle on the ground to eliminate the source of bacteria For orchards with severe disease in the previous year, before the disease occurs, lime is sprinkled on the ground (the amount of pesticide application is about 75 kg hectares); Soil with a high pH value (above 7) can be sprinkled on the ground: 1 part of fumei, 1 part of sulfur powder, 2 parts of lime, mix the three evenly, sprinkle on the ground, the dosage is 15 30 kg hectares.

Spray protection Spray Bordeaux liquid during the growing season, spray once every 10 15 days to protect leaves, branches, fruit ears, etc., and reduce the chance of infection.

In case of white rot, anthrax and other diseases, it is necessary to prescribe the right medicine, but pay attention to the alternate use of drugs, not continuous single medication. 80% mancozeb wettable powder, 50% fumebi wettable powder, 40% mycloconazole wettable powder, 50% carbendazim wettable powder and other agents can be used alternately for prevention and control. In addition, in order to prevent pesticides from polluting the ears after fruit coloring, the concentration of pesticides should not exceed the standard.
