What are the management skills of winter peaches? Peach tree winter management

1. Fertilization management: including base fertilizer, flowering top dressing, fruit top dressing and fruit picking top dressing, each stage must be paid attention to, and only after good cooperation can we have a bumper harvest.

Second, the prevention and control of pests and diseases. The prevention and control of pests and diseases cannot be ignored, and it is generally carried out on the principle of prevention and treatment. Every year before winter, the peach tree should be coated with stone sulfur mixture to clear the garden, remove diseased fruits, diseased branches, dead branches, weeds, etc., which can effectively prevent germs and insect pests.

3. Pruning work Summer pruning is generally carried out in June and July, mainly to remove too dense branches and too many new ones, which can make the tree more transparent and improve the quality of the fruit.

1. Apply base fertilizer, base fertilizer plays a very important role in the later growth of winter peaches.

2. Pruning work, winter pruning is mainly to remove dense branches, dead branches, diseased branches, weak branches and so on.

Park cleanup: remove fallen leaves, rotten fruits, weeds, etc. in the orchard in a timely manner, take them out of the orchard and burn them. Cleaning the ditch:

In his free time, he cleaned and maintained the drainage system in Taoyuan and improved the drainage system. Whitening: Whitening the trunk and main branches of peach trees can prevent frost and kill overwintering eggs and germs in the cracks in the bark.

Fertilization: Peach trees should be fertilized before they enter the dormant period, so prepare the basal fertilizer in October and start fertilizing in late October.

Reasonable fertilization: What fertilizer to apply to peach trees in winter? Juwuba mineral source potassium fulvic acid fertilizer is a humic acid fertilizer, which is immediately dissolved in water and has strong flocculation resistance, improves soil, regulates acid and alkali, resists heavy stubble, improves ground temperature, improves disease resistance, takes root and raises seedlings, protects roots and raises roots, prevents dead trees, improves fertilizer efficiency, increases production and income, and improves fertilizer utilization.

Winter peach tree pruning, how to prune these strong branches?

1. Plastic pruning.

1. Plastic surgery. Natural happy shape: leave 30-50 cm short shear rod in the year of planting, select and leave the three branches that stretch to the surrounding growth as the permanent main branch (do not leave the center rod), and obliquely insert two bamboo poles to fix it, and the main branch and the ground at an angle of 45 degrees. Another 5-6 new shoots are selected as auxiliary branches, and the tops are plucked and twisted at a length of 30 cm to promote flowering, and the next year is to hang fruit.

The main branch is topped at 40 cm to promote branching, and at the same time, the top tip is selected as an extension branch and tied to the oblique bamboo pole. In the second year of pruning, the extended branches are shortened to promote branching, and the extended branches are selected. This tree shape takes 2-3 years to form, and the main branch and its extended branches are meters long when formed.

Keep a ventilated light transmission strip of 20-40 cm between the rows. 2. Prune.

Young tree pruning: The focus of young tree pruning is to nurture the shape of the tree and nurture the main branches. In summer, timely twisting, twisting and topping of auxiliary branches can promote their early flowering. During winter pruning, part of the dense branches should be thinned, and the long branches should be lightly cut, and the long branches should be put more long and less stubbed, so as to expand the crown and increase the yield early.

Pruning of high-yield trees: The main purpose of pruning is to adjust the growth of the main and side branches, renew the branch groups, and prevent the fruiting parts from moving outward, so that they can produce abundantly every year. During winter pruning, the extended branches on the periphery of the canopy should be appropriately shortened and shortened to make the crown compact, and a ventilation and light transmission zone of 40-50 cm should be maintained between the rows.

The over-dense branches should be properly thinned, and the tree body should be kept sparse on the outside and dense on the inside, with few main branches and more side branches, which is conducive to high yield. Summer pruning is carried out from June to July, mainly to remove too dense and too many new shoots, so that the tree body is well ventilated and transmitted, so as to improve the quality of the fruit. Autumn pruning is carried out within 10 days after the beginning of autumn, by cutting off all the young branches at the top of the tree to prevent the autumn shoots from growing steeply and wasting nutrients, otherwise it is easy to fall fruits, crack fruits, and shrink fruits.

Winter pruning mainly prunes: over-dense branches, dead branches, insect branches, diseased branches, and weak branches.

2. Flower and fruit management.

1. Thinning flowers and fruits: This variety is very easy to flower, has strong self-flowering strength, and has light physiological fruit drop and pre-harvest fruit drop. In order to obtain high-quality large fruits, it is necessary to carefully thin flowers and fruits.

Fruit thinning is carried out in 2-3 times, the first fruit thinning is the first fruit at the top of the fruiting branch and the base part; The second time in late May to early June, the diseased and insect fruits, deformed fruits, and dense fruits were thinned out (according to the target yield, the fruit was determined by branches, and the interval of 15-20 cm was generally 15-20 cm, leaving one fruit) to maintain the leaf-fruit ratio at 50:1, and the yield per mu was about 2500 kg. After setting the fruit to before ripening, the winter peach will have a small amount of shrinking fruit, cracked fruit, and extra-small fruit, which should be cleared out of the garden in time after being found.

2. Bagging : The implementation of bagging can prevent pests and diseases from infecting and harming fruits, prevent fruit cracking, fruit shrinkage and fruit dropping, and can significantly increase coloring and improve fruit quality. Bagging is an indispensable measure for the successful cultivation of winter peaches.

Bagging is carried out in early June after fruit thinning, and insecticides and fungicides are sprayed once before and after bagging. According to the maturity situation, the bag is unpacked 10 days before harvesting, and the bag is generally unpacked around November 5 to 10 every year.

3. Pest control.

The main diseases and insects are: bacterial perforation disease, scab, leaf shrinkage, powdery mildew, leaf miner, mulberry white scale, aphid, thrips, leaf mites.

<> "Winter peach planting needs to choose acidic or slightly acidic soil, after land preparation and fertilization, flat land with a density of 2 to 3 meters on the slope. After planting, fertilizer and water management should be carried out according to the different growth periods of the planting cover, such as the winter peach tree that enters the harvest period 3 years after planting the branches, and generally fertilizes 4 times a year.

1. Soil management: peach tree root system is developed, but the distribution is shallow, mainly concentrated in 20-40cm below the surface, after early spring thaw peach tree germination in time to plane the tree tray, the depth is about 10cm, which can make the soil loose and aerate, prevent soil compaction, and reduce the competition of weeds for soil moisture and nutrients.

2. Fertilization: The branches of peach trees grow rapidly and the fruit development period is short, so fertilization should be timely and reasonable. Spring fertilization mainly refers to fertilization before germination, fertilization time, from the end of the month to the beginning of March, it is better to apply early in advance, and prepare for the material preparation of germination.

Fertilization should be determined according to many factors such as tree age, variety, yield, growth, climate, soil fertility and fertilizer type. Fertilization method: under the canopy, close to the root distribution area, dig 2 or 3 fertilizer pits, fully mix organic fertilizer with nitrogen, phosphorus and potassium fertilizers, and cover the soil in time after application.

In case of drought and rain before germination, light manure should be irrigated to resist drought and drainage.

3. In order to improve the fruit setting rate and promote the growth and development of young fruits and new shoots and the growth of roots during the flowering period, a mixed fertilizer of nitrogen, phosphorus and potassium should be applied once, and boron fertilizer should be sprayed appropriately during the flowering period, which is conducive to improving the fruit setting rate.

4. Water management: Although peach trees are drought tolerant and waterlogged, and sensitive to water, peach trees also need more water during the germination, flowering, fruiting and maturity periods. Lack of water during germination and flowering, abnormal germination, poor flowering and fruit set, and low fruit setting rate affect the annual yield.

Watering early spring water, after thawing, that is, before flowering, watering permeable water to meet the needs of germination and flowering for water.
