What should be done to deal with diseases in greenhouse grapes?

After the seedling stage, the growth period, the flowering period and finally the ripening period of the fruit, the grapes can be bagged and harvested after the end of the color change, during which the negligence of many growers leads to problems in the final link, causing a wide range of economic losses. After harvesting, the grapes are also subject to pest control, with protective fungicides immediately after harvest, and spraying the vines within the cycle until the leaves fall. This effectively improves pest control and ensures that there are no or fewer pests and diseases during the subsequent dormant period, which does not affect a large area of grape plants.

The vineyard should be inspected frequently, and diseased ears should be found, and the diseased grains should be removed in time for harmless treatment. Rational use or non-use of hormonal drugs to avoid peel damage and fruit cracking; Reasonable granulation thinning; Avoid over-tightening the spikes; Use fertilizers wisely, especially avoid excessive use of nitrogen fertilizers.

Keeping the shelves ventilated and light transparent requires frequent weeding, drainage, floor moisture and pest and disease removal. The grapes were thoroughly sprayed with a 500-fold dilution of the quick net.

Growing grapes is a good way, the really good way is due to being rich, not the first time planting, but also a test of a person's ability, knowledge, and knowledge, including nurturing, diligence, I also have a few years of grapes, learn a little, talk, smile a bead of one, : Mainly include: Learn from experienced old grapes, learn more, ask for more, negotiate carefully, not afraid of running errands, afraid of hardship is one of the best ways to grow good grapes.

Choose, choose, now on the market is the highest, easy to sell, delicious, popular new varieties, not only planting varieties, but also immature, ripe, late ripening, so there must be a large and small choice, grapes are a kind of sunshine, like neutral sandy soil, not arid and good watering conditions, timely drainage and drainage. Sufficient basal fertilizer should be applied, with 1000 kg of pig manure or cow manure or half manure per mu, or 500 kg of cooked chicken manure or duck manure, chemical fertilizer 5o kg (nitrogen, phosphorus, potassium) compound fertilizer per mu, plus 3o kg of trace element fertilizer, such as (calcium, magnesium, phosphorus) and so on.

Management, as the saying goes, three kinds of seven tubes, in the small seedling stage, the seedling roots and weeds are absolutely clean, preventing weeds and seedlings from being water, fertilizer, sunshine, wind or rain after the timely wind blowing down the seedlings. Timely insect prevention, disease prevention, generally small seedling stage Bordeaux liquid, insect prevention, general insect net can be, such as in the case of bean insects, manual capture can solve the initial results, every two to three ears, should not be too much, that is, to make the ears large, and consider the long tree, so that both sides at the same time less affected.

When the grapes are dark green and light green and are about to be bagged, the bagging time just happened to learn from foreign countries in China, which is ten years of history, it is too thin when bagging, you will be too honey and small ones before, you have to take it off, use chlorothalonil or other antifungal agents, anthrax and other germs will neutralize the blisters and make it full of crown medicine, such as bagging immediately after the liquid is dry, the time should not be less than two hours, the time is too long or it is raining, it is necessary to play how many sets, how many sets, 8 to 10, 16 to 18 afternoon, sunny. Bagging is indeed a good way to make the sugar on the grapes ripen quickly and quickly, with a fast color, to avoid dust contamination, but also to prevent birds and insects, and to protect the appearance of powdered sugar on the fruit.

To prevent steaming and sunburn, generally directly for two hours, it will be scalded on the surface of the fruit, the temperature of 36 degrees will make the fruit hot, the solution is mainly to let the leaves under the ears, do not let it be directly exposed, and now there is no good measure for steaming. Fruit cracking, generally a grape cracked spike, will destroy the entire ear, when the fruit has a high sugar content when torn, sugar outflow water, or bring flies, flies and bacteria, quickly ferment vinegar at high temperature, in a very short time will destroy the spike, solution, no water or little water, in case the rain roots can be built with plastic film to prevent too much moisture, another solution is to use a plow to cut the roots 50 cm, reduce water absorption.

Be sure to open the window often for ventilation, the temperature should be controlled at about 22 degrees when planting, in the process of cultivation must choose seedling cultivation, after thawing in winter, it should be pruned in time, must control the temperature in the morning and evening, to choose the right fertilizer and pesticide according to the planting density, you can choose the way of thin fertilizer and diligent application.

We must pay attention to the humidity and temperature in the greenhouse, use a hygrometer, so that we can regulate the environment in the greenhouse, we must pay attention to the light, and we must grasp the fluctuation range of temperature.

It is necessary to pay attention to the treatment of the frame, pay attention to the bamboo poles, or the situation of steel bars, be sure to pay attention to the inclination, and try to choose a membrane roof with a relatively large inclination.

<> application of basal fertilizer, but also the most important fertilization, and the quality and yield of the second year has a close relationship, with the goal of catty fruit and catty fertilizer, in late September in the grape root 50 cm from the root of the dig 60 cm deep pit, apply rotten agricultural celery Qiaojia fertilizer, per mu according to 50 kg of superphosphate and 10 kg of agricultural potassium sulfate mixed application. The main purpose of winter pruning is to make the branches of the vines reasonably spread over the shelf through artificial pruning, make full use of the growing space, increase the light, and achieve three-dimensional results, so as to form a high-yield, stable yield and high-quality vine shape.

Adult hanging fruit trees, plant spacing within 60-70cm from the main pole of the plant, digging depth of 50-60cm, width of 40-50cm along the groove, and then mu according to 4000-5000kg of high-quality columns (chickens, ducks, pigs) and 100kg of phosphate fertilizer, fertilizer mixed layer application into the trough backfill, after the application of timely irrigation of enough water. After the pruning of the grapes into the winter, the grapes enter the dormant period, starting from the branches, keeping 4 8 bud eyes, and pruning off all the branches at the top. It is good for light and ventilation.

Before pruning, the growth of the whole garden should be observed, and according to the plant situation and the actual yield of this year, the yield of next year and the winter pruning intensity of this year's disagreement should be determined, that is, the amount of buds left for each plant should be determined. Tie the vines off the shelf, after winter pruning, take the branches off the shelf, and take advantage of the trend to put the branches into the ground on both sides of the plant, and tie them with straw. If the leaves are damaged by frost and the nutrient reflux is not completed, then the quality of next year's flower buds will not be good.

From these two aspects, I think that the vines should be pruned and sprayed with stone sulfur mixture and covered with straw, and the second is to dig a hole 30 cm from the roots of the grapes and apply human and animal manure. Finally, the garden is cleared and all the fallen leaves and branches of the grapes are removed. Spray the whole garden with a 5-degree stone sulfur mixture.

Generally, the leaves of grapes will wither and yellow before and after the beginning of winter, and the process of yellowing the leaves is the process of nutrient reflux, and the grapes are protecting themselves. The return of nutrients from the leaves replenishes the shoots and flower buds in preparation for overwintering.

The first point of the whole Kai game chop link must remember it, the picking of this time should be mastered, the second should master the most basic picking skills, and the third point should be focused on the effect of the whole fruit sprinkling.

Generally, for every 500 kg of grapes, 1,000 kg of high-quality decomposed organic fertilizer is required, and phosphorus and potassium fertilizers are applied at the same time. Among the basal fertilizers, nitrogen fertilizer application accounts for 60 70 percent of the year, phosphate fertilizer accounts for more than 80 percent, and potassium fertilizer accounts for 30 40 percent. It is recommended to cover the ground of the vineyard with straw, and the thickness of the cover grass is about 20 cm, which can not only keep the heat and moisture by hand, but also inhibit weeds, and improve the soil after the straw rots.

For the newly built vineyard, the trench should be dug with a width of 60 cm, and then 3000 5000 kg of rotting organic fertilizer should be applied, mixed with fine soil and evenly mixed as base fertilizer, and then filled with a layer of topsoil in the ditch to lay a good foundation for planting seedlings after spring. Of course, in addition to basal fertilizer, before grape budding, flowering, and fruit set, it is also necessary to top dressing on the ground surface and spray potato fertilizer outside the roots. Celery shed.

Viticulture is generally carried out in greenhouses, so that the high yield of grapes will be very economical. The temperature gradually began to cool again, and the precipitation and wind continued for several days. At that time, the impact on the grapes during the winter period is very large, so how can the greenhouse grapes use winter management measures to get a good harvest next year?

Now I will organize the ideas for the winter management of greenhouse grapes.

Prune the vines

1.The right time for grape pruning: The most suitable winter pruning stage for grapes grown in greenhouses is after the grapes have fallen asleep after the main stem of the grapes has withered leaves, and it is now early to mid-December, and it will start in about ten days, preferably not too late.

2.Pruning of grapes: The pruning method should be decided according to the platform of grape planting, the different plant types, etc. However, it is best to cut off the pest branches of the grapes, as well as the branches that are too thick or too thin.

Disinfection of grape vineyards

Grape clearing: After the grape pruning is completed, eliminate all the dry branches and dead leaves in the garden and peel off the thick skin on the main trunk and main vine to carry out concentrated damage and burial to reduce pathogenic bacteria.

Disinfection and sterilization of grapes: use Baume 2-3 degrees dimethoate oxide and sodium pentachlorophenol to carry out a spray disinfection of the road surface, trellis and main stem in the garden. In the pom-pom stage of the main stem bud in early to mid-February, it was sprayed again with dimethoate oxide and sodium pentachlorophenol to remove pathogenic bacteria.

Grape shedding time

Greenhouse promotes planting, and the time of covering the film sooner or later directly affects the early and late ripening of grape fruits. Depending on the local climate, it should not be too early or too late.

Liquid fertilizerManagement

Immediately after the grapes are covered with enough water, the whole shed is closed, and 15kg of urea solution or 30kg of ammonium carbonate and 3kg of boron fertilizer are applied one week before the grape bud stage, and then water is injected once after application.

Temperature and humidity control after the canopy

After the grapes are covered and before germination, it is best to enclose the grapes in the whole shed, and relatively maintain the high temperature and low temperature in the shed. After the grape bud break, it is best to control the temperature between 5 and 30 and the air humidity to about 60%. The above are some aspects of grape winter management measures, grape winter management is the basic harvest is also an important stage, so everyone must not be careless in this link, jeopardizing the growth of grapes.

1. Pruning. Winter pruning is a complex and critical technique. The quality of pruning in the current year can affect the growth and development of the grapes in the following year or even in the next 2-3 years. It is essential to have a proper grasp of the pruning technique.

2. Cleaning and disinfection of the garden.

1. Clearing the garden: After the grape pruning is over, remove all the dead core branches and fallen leaves in the garden and peel off the old skin on the main stem and main vine for centralized burning and deep burial to reduce the source of disease.

2. Disinfection: Use Baume 2-3 degrees of stone sulfur mixture plus sodium pentachlorophenol to comprehensively spray and disinfect the ground, trellis and plant cover in the park. In early February, during the pompom stage of plant buds, spray again with a degree of stone sulfur mixture and sodium pentachlorophenol to eradicate the source of disease.

Yes, the soil should be protected and the temperature should be raised so that the grapes can be produced better and the quality of the grapes will be very good.

Clearing the garden: After the grape pruning is completed, remove all the dead branches and fallen leaves in the garden and peel off the cavity, remove the old skin on the main stem and main vine, and burn the celery and bury it deeply to reduce the source of disease. Qi Cong.

Viticulture is generally carried out in greenhouse facilities, which makes the benefits of grape yield more obvious. It's early December, and the previous temperature is starting to drop gradually, and it's been raining for many days and winding for many days. This weather had a great impact on the overwintering grapes.

So, how can winter management practices for greenhouse grapes be used to get next year's harvest? Let's sort out the ideas of winter management measures for greenhouse grapes.

How can greenhouse grapes use winter management for next year's harvest? First of all, the right time to prune the vines: the best time to prune the grapes in the greenhouse is in early December, when the vines have lost their leaves and are completely dormant.

It can start in around 10 days, preferably not too late. Pruning method of grapes: The pruning method should be determined according to the framework of the viticulture and the different tree potential.

But grape vines with insect pests, and vines that are too thick or too thin should be cut best.

Vineyard disinfection Vineyard cleaning: After grape pruning, all dead branches and leaves in the garden are removed, and the old skin on the main stem and main vine is stripped off, and the main stem and vine are burned and buried deeply to reduce the source of disease. Grape sterilization: use pommel 2-3 degrees of stone sulfur mixture.

and sodium pentachlorophenol on the garden floor, scaffolding.

and plants are fully sprayed and disinfected. At the beginning of February, when the plant buds were in full bloom, they were repeatedly sprayed with a sulfur mixture and sodium pentachlorophenol, the source of the disease. The time of grape cover greenhouse promotes cultivation, and the early and late mulching time is directly related to the early and late ripening of grape fruits.

Not sooner or later, depending on the local climate. After the fertiliser and water are managed by the hand oak to cover the grape shed, the lines are smooth, the front face is decorated with red and black, and the tail has a through-light and a double exhaust. The interior is very good, and the places that can be upholstered are all upholstery, which is very good.

Fully enclosed grape sheds, one week before the grapes bud break, urea per acre.

15kg or ammonium bicarbonate.

30kg + boron fertilizer 3kg, then irrigated.
