Can black nectarines be planted in greenhouses?

Black nectarines can be grown in greenhouses.

Black nectarine planting adaptability is strong, drought resistance, barren resistance, and high yields can also be obtained in thin mountain areas. In production, it is necessary to pay attention to strengthening early fertilizer and water**; Strengthen summer pruning, improve light, and promote fruit coloration; Control the amount of fruit left to prevent premature tree aging.

1. Fertilizer and water management, pre-promotion and post-control.

According to the fertilizer requirements of nectarines in each growth phenological stage, topdressing and watering should be carried out in time, mainly nitrogen in the early stage, phosphorus and potassium in the later stage. From seedling planting to early July, fertilizer and water management should be strengthened to promote rapid growth of the canopy. After mid-July, fertilizer and water are strictly controlled.

Foliar spraying of potassium dihydrogen phosphate on the foliar surface during the flowering, young fruit and fruit expansion stages of nectarines once every 10 days can help alleviate the competition between new shoot growth and fruit setting for nutrients and improve the fruit setting rate.

2. Pruning during the growing season.

The top of the nectarine tree has a strong advantage, many branches, fast growth of new shoots, and easy formation of flower buds, so it is particularly important to cultivate a high-yield tree shape early. The wound caused by pruning is smeared with a "callus antiseptic film" to sterilize and disinfect to prevent dryness and cracking.

3. Control the shoots to promote flowering.

Nectarine trees are relatively vigorous, and the branches are easy to grow wildly, so it is necessary to inhibit vegetative growth and promote flower bud differentiation.

Fourth, sparse flowers and fruits.

When the number of flower buds is large, most of the flower buds on the weak branches and the long and medium fruit branches can be thinned due to the pruning of long and redundant double flower buds and the late flowering buds that are stunted. A fruit thinning was carried out in mid-May, mainly to remove the combined fruits, deformed fruits, small fruits and base fruits, shoot fruits, etc. The second fruit thinning is carried out from late May to early June, generally leaving 2-3 fruits on long fruit branches, 1--2 fruits on medium fruit branches, and 1 fruit on short fruit branches, and the leaf-fruit ratio is not less than 50:

1. The spacing between fruits is not less than 20 cm.

Summary. Hello, dear, glad to answer for you, can do. Heilongjiang is suitable for planting nectarine, nectarine is a relatively easy plant to cultivate, and most areas of China are very suitable for planting it.

Hello, dear, I'm glad to answer for you, you can do the enlightenment. Heilongjiang Shikai Naihe planting nectarine, nectarine is a relatively easy plant to cultivate, most areas of our country are very suitable for staring at the spring to plant it.

Nectarine is a temperature-loving trace of the cultivation of the temperature withered belt fruit tree, the root temperature is 16 18, the branch growth is 18 23, the fruit ripening period, the average monthly temperature of the growth period reaches, the yield is high, ***, but the summer temperature is too high and easy to be sunburned. Nectarines are the most light-loving Wuzhou simple fruit trees, insufficient light, easy to cause long branches, flower buds are not easy to form, serious fruit drop, fruit quality decline. Nectarines are adaptable to a wide range of soils, but they are best found in loose, well-drained sandy and gravel soils.

1. Site selection and greenhouse: nectarine greenhouses should be built in a place with leeward and sunny conditions, high and dry terrain, good drainage and irrigation, fertile soil and sandy loam soil. Such a place can ensure the nutrients of nectarines and the required temperature and climate.

2. Variety selection: The nectarines planted in greenhouses should be planted with plants that are not particularly large, and the maturity period should be early or late to be more marketable, such as early red beads.

3. Seedling transplanting: When transplanting seedlings, it is necessary to pay attention to the application of bottom fertilizer, and then report the time to be moist suddenly, which is conducive to the survival of the plant. When transplanting, choose those seedlings that look robust for transplantation.

4. Plastic pruning: When pruning nectarines in greenhouses, pay attention to the requirements of tree shape and lighting.

5. Fertilizer and water management: Greenhouse nectarines should also pay attention to fertilization, especially during the flowering period and fruiting period, only enough nutrients can grow better.

6. Temperature and humidity control: Temperature control is very important, because if you want nectarines to be out of season, you have to control the temperature, deceive the plants, and make them have an illusion about the season.

7. Pest control: The prevention and control of nectarine pests and diseases in the shed is mainly prevention, comprehensive control, focusing on the prevention and control of peach perforation disease, peach aphid and mites. Diseases can be controlled with stone sulfur mixture, mancozeb, zebzeb and other agents; Aphids and mites are controlled with insecticides such as imidacloprid and aphid mite.

8. Management of flowering and fruiting period: The management of flowering period is very important, and it is necessary to pick it appropriately if the flowering is too dense.

Construction method: 1. On a branch group, one branch leaves the leaf buds to prepare, and one branch leaves the flower buds to let it bear fruit in the current year. In the next year's winter pruning, the branches that have been prepared in the previous year are left to bear fruit, and the branches that bear fruit are left with leaf buds to be shortened and prepared, so that they are fixed in a certain part to renew and alternate, so as to achieve three-dimensional fruit.

2. Leave fruit appropriately. Generally, a flower bud is truncated on a short fruit branch; 2 and 3 medium fruit branches; Leave 4 5 long fruit branches to reduce nutrient consumption and ensure fruit quality.

3. Overall branch weight. The number of branches and the number of branches increased from south to north, and the branches were cultivated according to the combination of large, medium and small methods. Thin out long branches and closed branches to facilitate ventilation and light.

4. If the angle is not open, pay attention to the selection of dorsal and lower branches as extension heads or use methods such as pulling branches to adjust, so as to facilitate the rapid transformation of vegetative growth to reproductive growth, and promote early fruit hanging and early yield.

Summary. Greenhouse nectarines do not need to be watered during the hard core, OK.

Pay attention to water regulation in the cultivation of nectarine trees, do not be too dry in the early stage, do not be too waterlogged in the later stage, peach orchards with irrigation conditions should be irrigated in time according to soil moisture, keep the soil moisture relatively uniform, do not make the dry and wet changes too large, advocate peach orchard grass paving, cover wheat straw, corn straw, etc. under the canopy, and the thickness of 15 20cm can also be covered with waste greenhouse straw curtains. The soil moisture content of the peach orchard covered with grass is 13% 19%, which can basically meet the water required for the normal growth and development of nectarine, and there is basically no need for watering in the case of severe drought. Cave fertilizer and water storage technology can be used in mountain peach orchards.

In addition, special attention should be paid to the drainage of the fruit in the later stages of growth. According to the weather forecast, before the rain comes, the canopy of the tree is covered with plastic film to allow the rain to drain smoothly and prevent the soil from absorbing too much water.

How to manage the nectarines in the greenhouse without pits.

Greenhouse nectarine hard core during the need to water the bird Zheng, to determine the nectarine tree cultivation pay attention to water regulation, the early stage is not too dry, the later stage is not too waterlogged, there are irrigation conditions of the peach orchard according to the soil moisture timely irrigation, to keep the soil moisture relatively uniform, do not make the dry and wet amplitude too large, advocate peach orchard grass, canopy under the cover of wheat straw, corn stalks, etc., thickness 15 20cm can also be covered with waste greenhouse straw curtain. The soil moisture content of the peach orchard covered with grass is 13% 19%, which can basically meet the water required for the normal growth and development of nectarine, and there is basically no need for watering in the case of severe drought. Cave fertilizer and water storage technology can be used in mountain peach orchards.

In addition, special attention should be paid to drainage in the late stage of fruit growth. According to the weather forecast, before the rain comes, the canopy of the tree is covered with plastic film to allow the rain to drain smoothly and prevent the soil from absorbing too much water.

Please give a thumbs up

If you don't sell it, it may be that the fruit is not sparse properly:

Nectarines in the early stage of the hard core of young fruits, that is, the young fruits are directly warped in 1 male Li with friends to carry out vegetables and fruits, vegetables and fruits should not be too stingy, some people for the interests of the year, vegetables and fruits can not be anything, resulting in overload of fruit trees, so that the nutrient consumption of the tree body is too large, resulting in the weakening of the tree, which acacia can not keep up, from the young fruit to the hard core period to cause fruit drop.

Yes, it is because the soil miscellaneous fertilizer is used too much, because the soil miscellaneous powder will affect the soil quality, and the quality of the trillions will also affect the quality of the Guoshi rental tree, which is closely related, so we should pay more attention when using simple soil miscellaneous fertilizer.

There is also a reason for this, in fact, when using chemical fertilizers, the more the better, but also pay attention to the dosage and ratio.
