Problems solved by technology

However, affected by global warming and extreme natural weather disasters, low temperature and freezing damage have occurred frequently in winter and spring in Xinjiang almond production areas in recent years, which has caused great economic losses and impacts on the almond wood industry in the production areas.
On the one hand, the spring flowering period of almond trees in the production area coincides with the strong wind and sandstorm in southern Xinjiang, which is very easy to form a cold snap or cold weather in late spring. At this time, the temperature changes sharply, and sometimes the temperature will suddenly drop from above 10°C to below 0°C, which is harmful to the environment. The flower buds, flowers and young fruits of the almond tree cause great harm, often leading to a large reduction or even no harvest of almonds; The temperature is low, and the snowfall is usually less than 50-100 mm. Affected by unstable cold currents and meteorological conditions, extreme low-temperature freezing damage will also form. At this time, the temperature will drop below -20°C. Due to the low ground temperature in winter, the soil Ice, almond root activity decreases, water supply stops, but the aboveground branches of the seedlings are in windy, dry and cold climate conditions, and their tissues are relatively young and the degree of lignification is low, so the water of the branches passes through the lenticels and wounds It is constantly lost, so the water supply of the tree body is unbalanced, and physiological drought occurs; in addition, due to the large number of seedlings, it is common to use artificial cold protection in the open field in the prior art, such as wrapping the trunk with straw and whitewashing, root neck cultivation, and fumigation. Convenience, once the seedlings are damaged by low temperature and freezing, the mild ones often cause the branches to wilt and the germination is slow and irregular. Seedlings and saplings on trees
In recent winter and spring seasons, severe low-temperature frost damage occurred in the almond wood production area in southern Xinjiang. Kashgar experienced low-temperature processes below -20.0°C for 7 consecutive days, and the extreme low temperature once reached below-24.1°C, setting a record high. According to statistics, the low-temperature freezing damage has caused severe freezing of almond branches and flower buds in the production area, and the rate of flower bud loss due to freezing damage is as high as 95%. Part of the aboveground branches of Danmu seedlings dried up or froze to death, causing heavy losses

Embodiment 1

[0031] In the late autumn season, choose a suitable place around the nursery to dig deep pits for artificial planting, and then use manual or mechanical operations to lift the seedlings in the nursery. Finally, the top of the seedlings in the pit is covered with coverings such as stalks and so on to carry out the wintering protection of the seedlings. The specific method for the full coverage of the almond seedlings and false planting to prevent the cold and survive the winter includes the following specific steps:

[0032] (1) Digging deep pits for artificial planting: Before the soil in the north is frozen, choose a place that is leeward to the sun, well-drained, and moist in the soil near the almond tree nursery, and dig deep pits for artificial planting. The height is the same, the length of the artificial planting pit depends on the number of seedlings, and one end of the bottom ditch of the false planting pit is made into an inclined wall to facilitate the seedlings to le...

Embodiment 2

[0040] In the present invention, the late autumn season is about 7 to 10 days before the soil in the north is frozen, that is, the middle ten days to the last ten days of November every year.

[0041] In the present invention, the depth of the artificial planting is rectangular and is in a north-south direction, and is perpendicular to the direction of the local winter main wind, and the depth of the artificial planting pit is equal to or slightly higher than the height of the artificial planting seedlings.

[0042] Among the present invention, one end of the ditch at the bottom of the artificial planting pit is made into an inclined wall on the south side, and the inclined wall and the ground form an angle of about 45°, so that seedlings lean against and stacked.

[0043] In the present invention, a certain amount of river sand soil with suitable humidity is piled up at the bottom of the artificial planting pit for subsequent use. The amount of river sand soil is according to ...

Embodiment 3

[0050] In the present invention, the roots of the seedlings are dipped in the mud, and the soil: carbendazim (wettable powder): water is mixed according to the weight ratio of 100:5:100 to 100:5:120 to make a paste-like thick mud The method of dipping the roots of seedlings and dipping in the mud is to hold the place where the seedlings are bundled with your hand, and make a 10-15 degree oblique angle between the seedling bundle or the stem of the seedlings and the horizontal plane of the mud, gently press the root side of the seedlings into the mud, and apply force evenly in the mud Pull from one side to the other; then lightly press the other side of the root system into the mud, pull it in the same mud, lift the bundle of seedlings to check whether the roots are all dipped in the mud, and put it aside after the inspection is qualified, waiting for false planting, if dipped twice Finally, the root system is still exposed, and then use the same method to dip the left and right...

Abstract

The invention discloses a method for Badam nursery stock whole-covering provisonal planting cold-proof overwintering. Before soil is frozen up, a hand-excavation north-south rectangular provisonal planting pit with the consistent height with a nursery stock and with certain length is adopted, and the nursery stock is lifted and bundled; after the nursery stock is subjected to root dipping and slurry dipping disinfection processing, soil, carbendazim and water are stirred at the ratio of 100:5:100 to 100:5:120 to obtain even soupy thick slurry; the root of the lifted nursery stock is dipped with the slurry; the roots of the nursery stocks are downwards intensively embedded into sandy loam in different rows in sequence into a cold-proof pit which is dug in advance for provisonal planting; halms or straws are vertically inserted at a certain distance to keep the nursery stocks ventilating; after the pit is fully planted with the nursery stocks, the nursery stocks are disinfected; the top of the provisonal planting pit is covered with a slipcover with a certain thickness. According to the method, the Badam nursery stock can be protected to go through the winter without being frozen to the maximum degree. Meanwhile, the method can perform the purpose of planting nursery stock provisonal planting in winter, the planting survival rate is high, and the method has a wide practicality.

Description

technical field [0001] The invention belongs to the technical field of overwintering and cold protection for fruit tree seedlings in northern China, and specifically relates to the technical field of full-covering false planting of almond seedlings to prevent cold and overwinter. Background technique [0002] Almond ( Amygdalus communis L. ) The scientific name is almond, which belongs to the deciduous tree of the subgenus Almond, which belongs to the Rosaceae Li subfamily. It is a unique dry fruit tree species and high-quality woody oil family tree species in the world and Xinjiang. Its kernels are rich in protein, unsaturated fatty acids, mineral elements, vitamins, enzymes and other components, which have important nutritional and economic value and are widely used in food, health products, medicine and chemical industries. [0003] As one of the suitable almond wood-growing areas, Kashgar in Xinjiang is also the only main producing area in China. At present, the cultiv...
