Electric heat push root

the use of
hotline
heating root is a high efficiency, easy to centrally manage the rooting method. Generally with dV series electric warm-up line buried in the root seed bed, used to improve ground temperature. The power of the dV series of power-added hotlines is 400 watts, 600 watts, 800 watts, 1000 watts 4 kinds, according to how many flexible choice of processing inserts.
the wiring method of the electricity-heated line: first measure the area of the seedling bed, and then calculate the wiring density, such as the length of the bed 3 meters, width 2. 2 meters, the electricity hotline using 800 watts (length 100 meters), its:
wiring channel number - (line length - bed width) forest length ( 100 - 2.2) / 3 - 32.6.
route 32.
the wiring spacing of the bed width pulmonary lines, 2.2/32, 0.06 (m).
note that the number of wiring lanes must be evend so that the two connectors can be at one end. Then use the plank to grow 3 meters, 2.2 meters wide wooden frame, the bottom of the box and around the shop 5-7 cm sawdust to do insulation layer, the two ends of the wooden frame according to the wiring distance nails on a row of nails, so that the electric hotline back and forth around In the heating bed, and then covered with plastic film, the film is covered with 5-7 cm of wet sand, and finally the rooting strip cut and treated with chemical rooting agent, according to the variety bundle buried in wet sand, the bed is covered with plastic film. Generally 1 square meters of seedling bed can be placed about 6000 plugs.
hotbeds are powered up every morning and evening. Power-up time, depending on the temperature of the bed, the temperature in the bed up to 25-30 degrees C can be powered off. Where conditions are necessary, it is best to install a thermometer to control the temperature at 25 degrees C. The use of the thermometer can not only save electricity, but also to observe the temperature and switch power supply procedures, to ensure that the root of the most suitable temperature and root smoothly.
recently, some places have used electrothermal tyring with better insulation to root out, but also obtained good results. The method is to first lay a layer of brick underground at the root, tile a layer of sawdust or sand, 5-10 cm thick, and then with a better quality plastic film to the two sides of the electric heating on the sand, the electric heating on the film flattened, carefully check whether there are loopholes, and finally on the film 10 cm thick wet sand or wet sawdust, and the treated strip neatly discharged on top. On the circuit, the first two or three days of control switch placed in the high-grade position, when the temperature in the sand rose to 20-25 degrees C when the use of low-grade insulation. The rooting process can be completed in about 10 days with electrothermal heating. In the nursery volume is not large, electric hotline and thermostat is not easy to buy, this method can be used to warm the root.
chemical treatment: the use of pharmaceutical treatment can effectively promote rooting. The main function of the potion is to strengthen the breathing effect of the insert, improve the activity of enzymes, and promote the division of living cells. There are many types of agents to promote rooting, of which 50 mg of khan d5i palladium butyric acid (1ba) or 50-100 mg of pyrethione (n from) soaked strip base 12114 hours is the best effect. In order to reduce the use of containers, with 300-500 mg of acetic acid quick root 5110 seconds, and then immediately rooting or inserting also has a good rooting effect.
abt root powder contains growth
hormone
and a variety of chemicals, is also a good rooting drug. Dissolve 1 gram of rooting powder in 500 ml of alcohol, then add 500 ml of distilled or cold boiled water and disinsoquently add 1000 mg/kg abt solution. The original liquid should be kept in a cool place and diluted when used. In general, when the grapes are inserted, the abt solution can be used to dilute the original liquid 10 times to 100 mg, dilute 20 times to 50 mg mg, to dip the cut strip base 2-3 cm at l for 2 hours, and then remove the insert for insertion. Under normal conditions, l grams of root powder can handle 4000-6000 bars. Abt root powder can also be used for green branch insertion.
No matter what kind of rooting method is used, in order to ensure good rooting effect, we must pay attention to the following points: (1) different rooting methods to urge root time is not the same, but the general most suitable rooting degree is the root element break through the cortical layer about 0.5 cm can be inserted, the root is too long to break the new root, affecting the root insertion into a live string. (2) The root time should be flexible. If the root is pushed straight into the open ground, the root should be slightly later, so that after treatment can be dewy planting, if the protection of the nursery, can be appropriate early rooting. (2) When heating the root, the root should have a gradual cooling process later, so that the new root adapts to the external environmental conditions before planting seedlings. (4) After the root treatment of the insert, in the insertion of the root should not be avoided damage to the root. After planting into the seedling bed, water should be filled, so that the new root and bed soil closely combined.。
