How to manage kiwifruit from June to July

It is recommended that you buy the seedlings of Zespri Kiwifruit in New ZealandThe effect of kiwi fruit 1, reduce cholesterol 2, ** diabetes 3, hair care 4, improve eyesight average cost a imported fruit

In July, kiwifruit entered the secondary expansion period and quality formation period of the fruit, during which the fruit accumulated nutrients, and the main agricultural operations were:

1. Drought prevention and drainage - in the high temperature season, keep the orchard soil moisture sufficient, and irrigate in time when it is dry; On rainy days, the orchard should be drained of water in time.

2. Anti-sunburn - sunburn is easy to occur during high temperature period, and fruit bagging can be used to prevent sunburn or sunshade nets. Bagging should not be too early, otherwise it will affect the normal expansion of the fruit, Jinxiang, Huayou, and Xu Xiang will start bagging in early to mid-July; Hayward began bagging in mid-to-late July.

3. Tree disc mulching - tree disc mulching can stabilize soil temperature, keep the soil loose and breathable, conducive to soil microbial activities, increase soil organic matter, preserve nutrients and other effects, and its covering materials include mountain grass, straw, wheat grass, etc.

4. Top dressing fertilizer - from late July to early August, timely top dressing fertilizer, such as 50 kg of low nitrogen, medium phosphorus and high potassium compound fertilizer plus 50 kg of enzyme bacteria biological organic fertilizer per mu, or 50 kg of straw fulvic acid organic fertilizer.

5. Summer pruning - timely topping, thinning of overly dense branches and winding secondary branches, and timely and evenly tying vines to improve the ventilation and light transmission conditions of the orchard.

6. Grafting - the best grafting period of kiwifruit is in June and July, and the survival rate of early and late is low. When grafting, the methods of tongue cutting, splitting, ventral grafting, and bud grafting can be used, and the survival rate of bud grafting and tongue grafting is higher.

7. Pest control - focus on the prevention and control of brown spot, gray mold, bugs, red spiders and other pests and diseases, optional.

When planting kiwifruit, you need to choose a place that is not prone to waterlogging. Before planting kiwifruit, dig a planting hole, and apply about 40 kg of farmhouse fertilizer as base fertilizer in the hole. In autumn, the kiwifruit seedlings are buried in the planting pit and watered thoroughly, and the scaffolding needs to be built after planting, and the fertilizer is used to prevent root burning.

1. Planting place.

Kiwis prefer to live in cool environments, need plenty of light to grow, and are afraid of drought, waterlogging, and severe cold. The planting site needs to be selected on the sunny slope, and the planting hole should be dug in advance before planting, and about 40 kg of farmhouse fertilizer plus phosphorus fertilizer, calcium fertilizer, magnesium fertilizer, etc. should be buried in it as base fertilizer.

2. Colonization. Kiwifruit seedlings are planted at a distance of 5 to 6 meters between autumn and spring, and 20% of the males are planted in the orchard for pollination. After the planting is completed, the root system of the kiwifruit seedlings can be more closely attached to the soil.

3. Erection of the frame. Kiwifruit is a vine-like plant, and once the seedlings are planted, a trellis is built for the seedlings to climb, usually using a horizontal trellis.

Fourth, fertilizer management.

The answer starts with choosing the right soil. Kiwifruit plants are suitable for soils with a pH below 7, and sandy soils are the best choice, and male and female plants should be planted. Because the kiwifruit plant is a dioecious plant, it must be planted with male and female, such as being cultivated in large quantities in orchards, and the ratio of male to female is 8:

1 ratio of planting, so as to ensure the highest yield. Colonization time. The general planting time for kiwifruit is in early spring and after autumn, of which post-autumn planting is the best choice, to build a scaffolding.

Kiwifruit is a liana, and it is necessary to build a large trellis or fence for it to climb and grow. Kiwifruit plants need adequate nutrients, and an appropriate amount of fruit fertilizer can be applied before planting, and then at least three times a year. After harvesting the fruit, organic fertilizer, phosphate fertilizer, nitrogen, phosphorus and potassium compound fertilizer should be applied.

The planted kiwifruit tree should have the thickest branches as the trunk that year, and the future plants only need to cut the branches short, and pay attention to the cut mouth It is best to leave four or five buds.

Kiwi fruit is rich in vitamin C, regular consumption can make your complexion more fair and ruddy, it also has the effect of lightening spots. People who grow kiwifruit know that the fruit expansion period of kiwifruit is June, and at this time we must timely thinning the kiwifruit, top dressing, irrigation and pest control, etc., so as to ensure the yield of kiwifruit. <>

Fruit thinning top dressingWhen we have about fifteen to twenty days of kiwifruit flowering, we have to thin the fruit for it, like some diseased fruits, small fruits or poorly fertilized fruits, we have to clean it up in time. On some of the good long-fruiting branches that grow better, we leave only three or four fruits. In general, we can keep two or three fruits.

If it is a short fruit branch, it is good to leave only one fruit, which can prevent the loss of nutrients. In early June, we should give kiwifruit top dressing in time, you can apply nitrogen, phosphorus and potassium compound fertilizer or microbial fertilizer and organic full nutrient fertilizer to it. At the same time, June is also the time when kiwifruit needs water the most, and we must avoid noon when we irrigate it, otherwise it is easy to cause kiwifruit trees to wilt.

Pest and disease preventionNo matter what kind of fruit is planted, we must timely prevent diseases and insects for fruit trees, the most common kiwifruit is spotted wax cicada, brown spot and Oriental small salary, etc., we can use cyhalothrin,and pesticide antibiotic 120 or polyantimycin. In mid-June, we can also hang a bag of predator mites on the kiwi to control spider mites. Finally, there are some weeds in the orchard, we should also clean it up in time to keep the orchard damp and cool, so as not to burn the tree tray by the heat.

Therefore, in June, it is an important period for the growth of kiwifruit, and we must sprinkle fertilizer on him in time to thin the fruit and set the fruit, remove pests, irrigate and weed, etc. Although June is very busy, but do a good job of these management work, our kiwifruit can grow more and better, I hope these technologies can be helpful to everyone.

The temperature in June is relatively high, so in June, we should prevent pests and diseases from removing weeds in time, and the leaves that are found to be diseased must be destroyed in time, and we must be watered in time to prevent dry seedlings.

Attention should be paid to watering, attention should be paid to weeding, and attention should be paid to disease control, and some nutritious fertilizers should be used so that it can be well managed.

At this time, it is necessary to thin the fruit in time, and then it is also necessary to set the fruit in time, and it is necessary to remove some deformed fruits or some diseased fruits in time, and then it must be watered in time, and it is necessary to fertilize in time, and more nutritious fertilizers must be applied, and it is necessary to ensure that the water is sufficient.

After the kiwifruit bears fruit, it is necessary to increase the area of light in time to ensure the ventilation and light transmission of the rows, so that the organic matter can be better accumulated. It is also necessary to increase the application of medium and trace beneficial elemental fertilizers, and special drug spraying should be carried out after discovering pests and diseases. And to increase the air permeability of the soil, so that the root system function is enhanced.

It is also necessary to reasonably control the shoots to ensure better growth of the branches and harvest them in time after maturity.

1. Expand the effective photosynthetic area

Flatten the drooping branches to the empty space of the shelf and the wire in front of it to maximize the effective photosynthetic area. In early to mid-August, for the fruiting branches other than the second wire, leave the same number of fruits in front of the top fruit, or cut the leaves several times the number of fruits, so as to improve the degree of ventilation and light transmission on the shelf surface.

2. Increase the application of medium and trace amounts of finch-modified elemental fertilizer, and carry out foliar spray

Use 2 3 catties of Maifan stone powder, and then apply it with water to you or Bacillus glialis when watering to improve the fertilizer efficiency of Maifan stone powder. In the later stage, brown spot, gray spot, anthracnose and other diseases are prone to occur, and at the same time, Peiqiao also has the phenomenon of early defoliation, for these conditions, it is necessary to use special drugs for these insect pests, carry out foliar spraying, spray once every 10 15 days.

3. Strengthen root function

Attention should be paid to keeping the soil loose and enhancing the permeability of its root system. Gardens with deep roots and poor root development should be sprayed near the roots with special drugs once every 20 days to restore the vitality of the root system.

4. Reasonable control of shoots and timely harvesting

In late August, it is necessary to control the shoots to promote the full maturity of the branches and vines, and improve the ventilation and light transmission of the shelf surface, so that the nutrient accumulation of the tree body. After reaching the harvesting standard, it is necessary to harvest in time, and after harvesting, the tree should be supplemented with nutrients in time to allow the fruit tree to recover in time.

1. Autumn is an important period for kiwi flower bud differentiation and nutrient reflux for storage, at this time, the amount of nutrient accumulation of the tree body affects the yield and fruit quality of the tree body overwintering and the coming year, and it is also a critical period for the fruit weight gain and improvement of fruit quality in the middle and late ripening varieties of unlisted varieties in the year, so the scientific management of autumn is very important. It can be sprayed with Jiamei Platinum, which can provide nutrients for it, ensure the safe wintering of the tree, promote the differentiation of flower buds, improve the rate of flower and fruit setting and disease resistance and stress resistance in the coming year.

2. When the autumn is just entered, the temperature is still very high, the weather is dry, and it is easy to have dry and hot winds, resulting in kiwifruit leaf curling or scorching and fruit burning. Therefore, it is particularly important to strengthen the water management of mature gardens during this period. When it is dry, it should be watered in time, and it is best to use the open grip spray method if possible, and keep the soil moisture by staring at the locust.

3. Autumn is the last peak growth period of kiwifruit roots, especially 1-2 months before defoliation, at this time, the root system grows fast and mostly absorbs roots, and the leaves also have a period of growth, photosynthesis is very strong.

4. Irrigation roots should focus on old trees, diseased trees, weak trees, and injured trees. Special attention is paid to the red yang kiwifruit, its bark is thinner, after fruiting is easy to cause nutrient deficit, cold and frost resistance is reduced, the next year is very easy to cause canker, irrigation roots can provide nutrients for it in time, to ensure that it completes the autumn nutrient reserves, reduce the incidence of the next year.

<> plan for the year lies in spring. Spring is an important time for fruit tree management, and this is especially true for kiwifruit management. So, how to manage kiwifruit in spring, and what are the specific management contents? The following items are the key points of kiwifruit spring management technology, which must be done well.

Due to the impact of rain and snow last winter, some farmers hastily pruned, leaving too many branches, and pruning branches with diseases and pests was not thorough. Therefore, it is necessary to complete this management link before the injury flow, and clear the branches out of the orchard in time.

Tying branches is also an important part of the management of kiwifruit trees in spring. Binding branches requires clear primary and secondary distinction, and the first thing to do is to choose the branches with good growth as the main branches. Secondly, the vine branches should be evenly distributed, which is conducive to the growth of the branches.

Scrape off insect eggs and lesions on tree trunks and branches in a timely manner. Use stone sulfur mixture liquid (50 grams of crystal stone sulfur mixture, 500 grams of quicklime, 4000 grams of shirt and water) or Baume 3-5 degree stone sulfur mixture for main stem whitening or whole tree spraying to reduce the occurrence of pests and diseases in the future.

Kiwifruit should strengthen the prevention and control of canker disease in spring, especially Hongyang and other varieties are susceptible to canker disease, after germination, 600 times of thiomycoccin copper or 1 000 times of agricultural streptomycin can be added to prevent canker disease every time it is sprayed.

Late frost damage generally occurs in the early morning of the night from late March to early to mid-April, and it should be paid attention to the weather forecast and the minimum temperature many times a day after budding to do a good job of prevention, especially in the low pit land, to ensure a bumper harvest.

Before the arrival of night frost, 7 500 15 000 times of blue care spray can be used during the day, and antifreeze spray can also be used to prevent frost damage; At night, when the temperature drops to 1, 4 5 wet firewood and grass piles are placed in the kiwifruit orchard per acre to light the smoke.

If the late frost damage is relatively severe, spray 7 500 15 000 times on the second day, and spray 15 000 times after 3 7 days, which can effectively reduce the loss of frost damage.

Spring is the season when the maximum amount of soaking is taken, and the quality and quantity of shoots directly affect the yield of the year, so sufficient fertilizer must be applied.

Kiwifruit generally begins to germinate from mid-March to the end of March, and it is advisable to apply nitrogen fertilizer ammonium bicarbonate kg to the plant, spread evenly in the annular furrow, and cover the soil with 10 15 cm after fertilization. The amount of fertilizer should not be too large and too concentrated to prevent fertilizer damage. After fertilization, fill with water in time.

Pre-flowering fertilizer is also suitable for fast-acting nitrogen fertilizer ammonium bicarbonate or bacterial fertilizer, and kg of ammonium bicarbonate is applied to the plant, and the use of bacterial fertilizer is based on the product instructions. Pre-flowering fertilizer should be applied 10 days before flowering, and irrigated in time after application.

The planting methods of kiwifruit are: seedling cultivation, seedling management, garden selection, transplanting and planting, and later management.

1. Cultivate seedlings

Before planting kiwifruit, cultivate small seedlings, which can be cultivated by sowing, stripping, cuttings, grafting and other methods, among which grafting is the most common way to reproduce, and suitable methods can be selected to cultivate strong seedlings. For convenience, you can also go directly to the market to buy good quality seedlings.

Second, seedling management

After the seedlings are unearthed, they should build a shade net in time to block the strong direct light, otherwise the sun exposure is not good for the seedlings. When the kiwifruit grows to 3 true leaves, the seedlings can be thinned to remove the thin seedlings, sick seedlings, and dead seedlings.

3. Garden site selection

The root system of kiwifruit is fleshy, very fragile, and cannot tolerate stagnant water. Therefore, we should choose a place with deep soil, fertile nutrients, loose texture and good drainage to build a garden, with appropriate drainage and irrigation facilities.

After the garden is selected, the planting soil should be ploughed and sorted, and the weeds on the soil surface should be removed in advance, and the stones on the soil surface should be picked up. Apply base fertilizer to the soil to ensure good fertility, mainly with organic fertilizer, with the appropriate amount of compound fertilizer.

Fourth, transplanting and planting

Choose to plant after the kiwifruit leaves to the early spring of the following year before the kiwifruit sprouts, when planting, the plant row spacing should be determined according to the way of cultivation, the density of the vertical frame is 2 meters 4 meters, the T-frame planting density is 3 meters 4 meters, and the planting density of the flat roof trellis is 3 meters 5 meters.

5. Post-management

Regular cultivation and weeding, reasonable application of fertilization, to ensure good nutrients, pruning and shaping of kiwifruit trees.
