Method for plan peach trees in greenhouse

1, prepare seedlings.

Buy seedlings: it is advisable to buy seedlings after autumn and before the Spring Festival. Buying seedlings after the Spring Festival is prone to mixed varieties and lack of good varieties. The row spacing of greenhouse plants is about 0.9× 1.8m, and the planting per mu is about 4 1 1 plant.

Seedling transportation: loading above zero, sealing after wet seedling. When the seedlings get home, they should be unloaded above zero, covered tightly with heat preservation and moisture preservation, and it is strictly forbidden to put them in the environment below zero.

Storage of seedlings: if the seedlings are not planted immediately after purchase, there are two storage methods, namely, burying the soil and following in.

2. Planting time

Planting seedlings in autumn is not delayed, and they grow vigorously before the leaves turn yellow and freeze. Autumn planting needs cold and dry prevention, especially in cold areas in winter, such as Northeast China and Inner Mongolia, so it is not safe to overwinter and plant in autumn.

Sowing seedlings in spring is slow and weak, and the time is1-April. After thawing and before germination, the later the soil grows, the weaker it grows. Fruit trees in greenhouse are most suitable for planting in spring, because vegetables are produced in greenhouse in autumn and winter, and fruit seedlings need to be dormant at low temperature, so they can't grow normally when heated up. In addition, fruit trees in greenhouse can also be planted first and then shed.

3. Land preparation and soil cultivation

The row spacing in the open field is about 2.5m, and that in the greenhouse is about1.8m.. In the open field, it can travel north and south or east and west, and in the mountainous area, it can be arranged along the contour line. In winter, greenhouses are arranged from north to south and from west to east. The row direction of the arched shed is perpendicular to the shed direction, that is, the north-south shed runs east-west, and the east-west shed runs north-south. Ridge along the road, the ridge height is about 20 cm. There are two methods of soil preparation before ridging.

Deep tillage in the whole garden: the ground is sprinkled with fermented manure, generally about 5 cubic meters/mu, and the new shed 10 cubic meters/mu or more. The old shed has high organic matter content, so it is not necessary to apply manure. Then turn it over about 40 centimeters deep.

Trenching along the line: the depth is 60-80 cm and the width is 80- 100 cm. The lower part is filled with about 500 kg of mixed soil of weeds, and the upper part is filled with about 5 m3/ mu of mixed soil of organic fertilizer until it is filled. If the cooked soil is not enough, you can dig from the row, scatter the core soil between the rows, and then the water will sink.

4, seedling treatment

Before planting, all rootstock buds are removed, leaving only grafted buds and removing the binding film.

5. Use pollination trees

At least 2 varieties should be planted alternately or alternately, and different varieties must meet at flowering stage.

6, planting on the ridge

First plant the seedlings on one side of the ridge, with the north-south marriage interface facing east and the east-west marriage interface facing north. The plant spacing in the open field is about1.25m, and the plant spacing in the greenhouse is about 0.8m. When filling the soil, it vibrates up and down like garlic, filling the rhizosphere with fine soil.

Continue to pull, so that the line of yin and yang of the seedlings is 5- 10 cm above the ground. On the day after planting, water is poured once, and after the water seeps, the soil is buried continuously, and the soil of seedlings is more than 10 cm, and the soil of buds is more than 1 cm (scraping the soil to expose grafted buds before germination, spraying pesticides). At this time, the seedlings should be planted on the ridge, never deeply planted, and the line of yin and yang should not be lower than the ground level. In the future, with the growth of fruit trees, we will continue to raise the soil ridge, at least 30 cm above the ground.

7, seedling stem

The bud was cut flat at 1 cm above the joint. The small root system of seedlings is about 50 cm, and the large root system is about 100 cm.

8. Moisturize and maintain vitality

The key measure to ensure survival is to keep water. First, cover the ridge with 5 cm thick wet grass, and cover the grass with plastic film to keep the humidity and raise the ground temperature. Scatter soil around the trunk to prevent hot air from coming out of the membrane hole and scalding the trunk. Cut off all branches, leaving only one trunk to reduce water evaporation.

The seedlings are wrapped in newspaper to reduce water evaporation, and the upper end is untied when sprouting. You can also wrap a plastic film around the seedlings to reduce water evaporation. Don't wrap it in multiple layers, or the seedlings will freeze and die day and night. Erase the rootstock buds in time after germination, otherwise the grafted buds will not grow.

If planted in a greenhouse, the temperature should not exceed 28℃ within one month after planting, otherwise the seedlings will germinate before the emergence of new roots, and evaporation and water loss will lead to wilting and death. Crops between rows do not affect the light of seedlings, so it is best to arrange short-stem crops with large demand for fertilizer and water. If you plant in a greenhouse, you must pull out the vegetables in early May.

9. Accelerate growth

After planting, water every 7- 10 days to keep the surface moist until September. During the next heavy rain, you can water less once, but light rain can't replace watering. From May to August, before each watering, take 8- 16-8- 16 compound fertilizer No.2, melt it in advance, and smear it with water. Spraying No.24 foliar fertilizer on the bottom of leaves every 15 days.

Extended data

Planting in greenhouse can prevent freezing injury. After beginning of winter, the temperature will drop, especially after June 5438+February, and there will be frost or even freezing. To prevent plants from freezing, the method is to cover a layer of non-dripping film in the greenhouse, and the places around which there is no dripping film should be hung to the ground and trampled to death. Open the vents to demist during the day and close the surrounding vents at night to prevent cold air from entering, which can ensure that plants are not frozen.
