The vines will ripen early because of the lack of water, can it be manipulated manually?

Sodium synchloride promotes precocious ripening.

4 grams of sodium nitrate phenol mixed with 150 kg of water, inhibiting the growth of autumn slightly, concentrated adjustment of the plate of nutrients to transport to the right of fruit ears, fruits, not only to promote the expansion of fruits, but also to significantly early maturity, so as to reduce or avoid the fruit tree "ring Su" small surgery, early ripening effect is obvious, experiments have proved that the contrast without treatment to early color maturity 10-15 days. For the ring stripping technique, the opening should be small, and the ring peel is best wrapped with colored tape to promote healing, and the effect is better if combined with sugar and color enhancement measures. However, it should be noted that the effect of the strong tree is obvious, the weak tree is not obvious, and some have ***, resulting in serious weakness of the plant.

For the vines that are surgically operated, foliar sprays of sodium nitrate phenol plus bacteria are sterile, which is conducive to wound healing and prevents bacterial infection.

1. Control the output. The vines have limited nutrients, too much fruit, and the ripening period is delayed or even not ripe. To improve the quality of grapes, you can't blindly pursue yield.

Generally, the yield per mu is 2000 3000 catties, and the grape yield is usually adjusted according to the cultivation level, grape variety and quality requirements. The yield was controlled and adjusted from the aspects of the number of buds left in winter, the number of buds in spring, the number of new shoots, the number of fruit branches, the number of inflorescences, the size of inflorescences, the size of fruit ears and the number of fruit grains.

2. Winter pruning. Cut off a large number of excess branches, control the number of effective sprouts, and ensure that there is enough nutrients when the sprouts germinate**.

3. Wipe the buds. As needed, wipe off excess buds and concentrate nutrients and moisture on the effective buds that remain.

4. Fixed-branching. According to the predetermined yield and tree potential, the amount of branches is determined to ensure that nutrients and water are concentrated and effective on the new shoots.

5. Thinning the inflorescence. According to the predetermined yield and tree potential, the fruit-to-branch ratio is controlled, the number of inflorescences is determined, and the inflorescence is shaped.

6. Topping and secondary tip management. Adjust the relationship between vegetative growth and flowering and fruiting, and promote inflorescence growth and flowering and fruiting.

7. Water and fertilizer management, focusing on water management. The whole growth cycle requires a lot of water from the time the grapes are unearthed until they are buried in the winter, so in addition to the flowering period and the fruit coloring period, it is important to ensure that there is enough water, and as long as the weather is hot and it does not rain, it is necessary to water it to ensure that the growth needs of the plants are met. Fertilizer is generally not applied during this season, and some fast-acting phosphorus and potassium fertilizers are applied if necessary.

Generally, after the grapes are harvested, organic fertilizer is applied to the roots as a base fertilizer.

8. Ear management. According to the variety, determine the shape and size of the fruit spike, and thin the excess fruit grains.

9. Control pests and diseases. Make sure that there are enough leaves and shoots to produce organic nutrients for the fruit to grow.

10. Harvest at the right time. The fruit is harvested in time when it is fully ripe.

11. Apply basal fertilizer in autumn. After the grapes are harvested, organic fertilizer is applied to the roots as a base fertilizer. It can be fertilized in the form of furrows, radial furrows, and holes, and irrigated in time after covering the soil to promote nutrient absorption.

12. Winter pruning. After the grapes have fallen leaves, winter pruning is carried out according to the shaping and bud retention plan, which is usually done before burying the soil to protect them from the cold. In areas where there is no need to bury soil to protect against the cold, it can be completed before the spring injury, and the coldest season is generally avoided.

13. Bury the soil to prevent cold. In the northern region, after pruning in winter, bury the soil in time to prevent cold, which is generally completed before the soil freezes, so as to avoid the branches and vines from freezing and improve the germination rate in the second year.

Seedless treatment, generally before and after grape flowering, the inflorescence is treated with seedless agent to form a seedless fruit, reduce the hard core stage in the fruit ripening stage, and promote the early ripening of the fruit.

Nuclear-free treatment requires a strong tree, a certain level of management technology, and the most important thing is to control the yield, otherwise the gains may outweigh the losses.

Nitrogen fertilization will cause grapes to grow green, and new shoots compete with fruit ears for nutrients, resulting in late ripening of grapes. It is not recommended to apply nitrogen fertilizer during the growing season, and a small amount of fast-acting nitrogen fertilizer can be applied in the early growth stage. It cannot be used in the middle and late stages.

Gibberellin?! That's to promote seedless grapes, ethylene can. But how to do gas hormones. Auxin analogues to promote ethylene production in the body? If you bought it and didn't overcook it, you can put it aside with an apple. Ask an expert for agricultural production.

Ethylene can promote fruit ripening.

The following methods can be used to ripen the grapes early: winter pruning, bud mopping, pruning, topping and tip management, and pest control.

1. Winter pruning is to ensure that there is enough nutrients when the bud eye germinates**.

2. The purpose of wiping buds is to concentrate nutrients and water on the effective silver travel buds left.

3. Pruning is to ensure that nutrients and water are concentrated and effective on the new shoots.

4. Topping and secondary tip management are to promote inflorescence growth and flowering and fruiting.

5. The control of pests and diseases is to ensure that there are enough leaves and branches, and the organic nutrients produced by them are supplied to the growth of fruits.

(1) Use the natural environment to choose places with low temperature and high altitude to delay germination and flowering, and the development process will be delayed accordingly, so as to delay fruit ripening.

2) The use of plant growth regulators to delay the ripening of grape fruits, the better growth retardant is ATA (2-benzazolethioacetic acid). When the young fruit grows to the beginning of ripening, spraying 1 time 2 times 10 mg kg 15 mg kg concentration of ATA liquid on the fruit spike can significantly delay the ripening of the fruit, but it should be noted that the concentration of the liquid medicine can not be higher than 20 mg kg, otherwise it will cause pesticide damage, and the grape leaves are more sensitive to the drug, so be careful not to spray the liquid medicine on the leaves when spraying.

At the same time, spraying 50 milliliters of 100 milligrams of naphthalene acetic acid and 1 milliliter of 2 milliliters of gibberellin after the grapes are colored, can also significantly delay the ripening process of the grapes and prevent the ripening of the fruit from falling off.

3) Control of environmental conditionsIn the growing season of delayed cultivation, especially in July and August, shade nets are used to reduce the temperature and light intensity, control the growth rate of grapes, delay the fruit ripening process, and promote the delayed ripening of fruits.

After autumn, irrigation and cooling measures are used to delay the growth and development of grape fruits.

4) Fruit baggingFruit bagging is a technical measure that must be adopted in delayed cultivation, in high altitude areas, it can not only delay the ripening of fruits, but also prevent excessive ultraviolet rays and too dark fruit coloring in plateau areas, which is more important for some bright red varieties, such as red earth.

A: Good growth of grapes requires suitable soil, fertilizer, light, temperature, moisture, etc.

1. Soil. Soil is the basis for the growth of crops, and the condition of the soil directly determines the growth condition and fruit quality of the grapes. The two-pronged approach of organic fertilizer + microbial agent can increase soil nutrients on the one hand. On the other hand, it can also regulate soil activity, reduce harmful bacteria in the soil, and reduce the occurrence of soil-borne diseases.

2. Fertilization. Fertilization, irrigation, etc., can affect the vitality and nutrients of the soil. Therefore, we must do a good job in the basic principles of less fertilizer, less water, and many times. During the flowering period, the application of phosphorus fertilizer should be increased, which can preserve flowers and promote fruits, and improve the stress resistance of grapes. At the swelling stage, it is necessary to increase the amount of high-potassium fertilizer, which is a critical period for the transformation of grape taste, so it is very important to use fertilizer.

3. Illumination. Light is an indispensable energy source for the photosynthesis of grapes, and it is the driving force for the energy and material circulation of grapes. Therefore, light is also one of the most important factors in the growth of grapes. Theoretically, the vines do annual light for 1300 to 1500 hours.

Fourth, temperature. Temperature is one of the most important factors affecting grape growth, and the right temperature can promote the healthy growth of grapes. Theoretically, the average annual temperature required for the growing season of wine grapes is 10 20 (depending on the grape variety). When the spring temperature reaches 7 10 °C, the grape roots begin to move, and at 10 12 °C the buds begin to break and new branches develop.

As the temperature rises, it begins to bloom and bear fruit. The suitable temperature after the results is between 25-30°C. During the growth of the grapes, both high and low temperatures can cause damage to the grapes.

5. Moisture. Too much rain and too little rain can lead to malnutrition in the grapes, which also affects the quality of the wine. Grapes need a lot of water to grow in the early stage, and the lack of water will also affect their fruit. In general, it needs less water in the later stages of fruiting, and if the soil moisture is too high, the whole vine will grow quickly and not bear fruit, and if too much water accumulates in the soil, it is also very likely that the vine will rot roots.

The temperature should be controlled between 20 and 30, and the water must be sufficient, and then it should be actively fertilized, so that it can grow well and develop well.

It can survive in some places with higher altitudes or higher latitudes. I like the sun very much, and there should be a special amount of water and light in my life.

In some well-drained soils, there is a very good sun exposure during the day, the temperature is not particularly high, the air humidity is not particularly large, and there is not much wind.

"Grapes are drought-tolerant plants that can be cultivated in most places in the northern cavity area, and areas with more annual precipitation are not conducive to grape cultivation. However, water is indispensable for the growth and development of grapes, especially in the early stage of growth, and a large amount of water is needed to form vegetative organs. If it is too dry, the leaves will fall and even die.

Grapes need sufficient water in the bud stage, new shoot growth stage, and young fruit expansion stage, and should be watered once every 7 to 10 days, or the water should be stored to protect moisture. ”

There are four reasons why grapes drop a lot of fruit before they are ripe:

1) When the physiological fruit drops to 3 4 mm in size, a part of the fruit will fall off due to malnutrition and stop development. This is a self-competing fruit thinning of nutrients, which can improve the quality of the fruit. However, in order to prevent excessive fruit drop, the growth of new shoots should be controlled.

At this time, it is necessary to water less, avoid the application of closed nitrogen fertilizer, and apply phosphorus and potassium fertilizer.

2) During the period from hard core to coloring, if the temperature is as high as 32 42, some of the grapes will be damaged due to direct sunlight, and they will turn black and shrink. This is due to the excessive application of nitrogen fertilizer in the early stage, and the leaves grow too large and aggravate the sunburn degree. In summer, it is necessary to prune reasonably, in addition to retaining shade on the fruit spikes, appropriately cut off some new shoots, which can reduce the degree of sunburn.

Potted grapes can be covered with umbel amniotic paper on the top of the ears to protect the fruit from the sun.

3) Disease: Fruit-falling grapes like dry sedan chairs and less rainy climate. For example, in the rainy season, high temperature and high humidity are most prone to diseases, among which downy mildew, anthracnose, powdery mildew, black pox, etc. will cause a large number of fruit grains to fall off. In addition to the selection of disease-resistant varieties such as Jufeng, white banana, black Orin, red Fuji, Combayer, and turquoise, it can be sprayed once before and after germination

200 Bordeaux liquid, spray the same amount of Bordeaux liquid 200 times every half month to prevent disease; It can also be added with a baume 3 5 degree stone sulfur mixture before germination2 sodium pentachlorophenol destroys overwintering pathogens.

4) When the insect pest falls fruit at high temperature and dryness before and after early ripening, the reproduction of red spider is the fastest, especially in the family potted grapes, more attention should be paid to the prevention and control to avoid fruit drop. You can use a mixture of 40{bf} dimethoate 2000 times and 40{bf} dicofol 1000-1500 times, spray 2 3 times. In order to avoid pesticides polluting the home environment, garlic extract can also be sprayed.
