Reproduction of softwood cuttings
What good is this method?Green cuttings multiply many fruit, berry and ornamental crops • In favorable conditions seedlings output is high and reaches 95%.This method is also simple, but there is one "but": if you plan to plant a large number of cuttings, it is necessary parnikig and better with greenhouses Fog-forming units.
If the number of cuttings planted in the hundreds or so, you can make the simplest cherenochnik.This bed covered by her arcs mounted on a polyethylene film, the edges of which are pressed firmly to the ground.5-15 rooting cuttings can be just under the hood of a 5-liter plastic bottle.
How to prepare the ground?
basic requirements are as follows:
- at the bottom of the ridge (at a depth of 20-25 cm) is good drainage from the expanded clay, gravel, crushed stone layer of 10-15 cm;
- fertile ground layer (already compacted) should be about 20 cm;
- on top poured layer of clean river sand thickness not less than 5 cm;
- prepared in such a way as the
Most garden plants by cuttings in the period of intensive growth of annual shoots, that is, in late June - early July (for the central part of Russia).However, there are exceptions.For example, the edible honeysuckle in late June, shoots begin to bed
vesnevat and therefore worse than root.Of grafted this culture begin after June 10.Lilac and rowan planted on rooting even earlier - during the period of flowering, in late May.But crops such as buckthorn and Actinidia root better in shoot growth attenuation period - in mid-July.
general rule for all crops: cuttings are cut in the early morning, before the heat.
From what plants better to take cuttings?
so-called uterine plants should be young, 3-4-year-olds.Moreover, they may both be imparted, and the root-genuine.For cuttings of selected annual gains with good illumination
better positioned cherenochnik in partial shade trees or on the north side of the greenhouse.In this case, during the hot summer days, temperatures inside a film will not rise too high, and the humidity will remain high longer.
tion of the crown length of 40-60 cm. Work-noukorenyaemyh plant is better to cut the short side shoots.You can not cut into cuttings with the fat shoots (tops), since they do not take root.
Cutting green cuttings
The average size of the cuttings for most crops is 12-17 cm. Short cuttings take root properly, but
doraschivat longer before receiving standard seedlings.Long (size 25-30 cm) worse than root, but such rocks like lilac, mock orange, Thuja long cuttings are preferred.
lower cut of the cutting is oblique and below the kidney 0.5 cm, upper section - 1 cm above the kidneys.The lower 1-2 leaves are removed, retained only a short petioles.In cultures with large leaves (viburnum, hydrangea, grapes maiden) shorten the remaining leaves to 1/2 or 1/3.
use rooting stimulants
To accelerate root formation, and increase the percentage of rooted cuttings, they are treated with special substances.The best results are obtained when using the IAA, or rather its aqueous solution.
sale always there kornevin, which is used both in pure form and in solution.For cuttings
bind processing in bunches, immerse them in the solution to a depth of 2.1 cm for 14-16 hours.Then rinse with clean water the cuttings and planted.
Cuttings are planted vertically to a depth of 1-2 cm distance between rows of 10 cm, and in a series of 5-8 cm, depending on the size of the leaves.Planted cuttings abundantly watered and cover paznik or greenhouse.
Period rooting green cuttings in various different cultures.In legkouko-
Renia plants first roots appear after 3 weeks.But in this period of the cuttings need constant care.All attention should be focused on maintaining the Turgai-ra in the leaves, because the cuttings do not have roots, and the water in them does not come from below.Therefore, only the creation of high humidity in the greenhouse cherenochnike or moderate temperature (optimum temperature + 23-27 ° C) will ensure the viability of green cuttings.Reduce the temperature in the heat, you can make shade with gauze, whitewash and so on. D. And that leaves all the time were wet, cuttings are often sprayed or watered
from a watering can with a fine strainer (in the first 1-2 weeks of each hour).You can focus on the condensate within cherekochnika: If the film inside the droplets zody, the IAM high humidity.With the subsidence of the lower leaves from the cuttings they are collected that there was no foci of fungal infection.
When first formed roots, spend the first feeding of nitrogen fertilizers.After mass rooting greenhouses on airs evenings, tempering tender plants, and after a
In crops such as cherry, plum, cherry plum, lilac, conifers, white and red currant root well combined shanks - green cuttings with a piece of last year's cutting sizeno more than 0.5-1 cm. They are called cuttings with a heel.
zremya fully open.It is better in cloudy weather.
Transplant rooted cuttings can fall or spring.In the winter young plants roses, clematis, hydrangeas and other heat-loving crops are covered with spruce branches and oak leaves.
