How to improve the survival rate of gold leaf privet
Gold leaf privet has been widely used in landscaping due to its golden leaf color and its resistance to pruning. It is of utmost importance to quickly multiply the privet of the golden leaf and improve the survival rate of its cuttings. The cutting method is now described as follows.
The survival rate of the gold leaf privet cuttings was closely related to the substrate of cuttings, the concentration of rooting powder, the degree of lignification of the cuttings, and the cutting time. The rooting rate of the cutting substrate with coarse sandy soil was higher than that with fine sandy soil, and the rooting rate was lower with the lower concentration of 1/1000 liquid of the axillary root powder. The rooting rate of cuttings was higher than that of semi-lignification, and the summer cutting had higher rooting rate than that of autumn.
Before the cutting of the golden leaf privet, first use a stick that is slightly thicker than the cuttings to cut the hole, and then insert it slightly to make sure that the cutting density is not in contact with the leaves and the distribution is even.
Using two-year-old gold leaf privet shoots, it is best to use a lignified part cut into 15 centimeters of cuttings, remove all the lower leaves, left 2 to 3 leaves can be on the upper cut from the bud 1 cm flat Cut and cut under the oblique cut into horseshoe shape on the back of the bud. The cuttings were cut with coarse sandy soil, and the cuttings were sterilized with 0.5% potassium permanganate for 1 day before cutting.
Then sprayed with clear water and then covered with plastic film, with half of the surface of the soil compaction, the rest with bricks compacted, so that the water, and then use the curtain to shade. Spray water twice a day before the rooting (spray time is between 10:00 am and 11:00 am and 13:00 pm and 14:00 pm) to cool and moisturize, keep the temperature inside the greenhouse at 20°C to 30°C, and the relative humidity at 95% the above.
Every day at noon, proper ventilation, summer to prevent its decay, spray 800 times carbendazim for 3 days, spray again 10 days later. After 21 days or so, after two days of small ventilation, the plastic film can be peeled off in the morning and in the evening, shaded with a curtain at noon, and more water is sprayed. After 3 days, all of the water is removed.
After hardening the seedlings for 4 to 5 days, they can be transplanted on cloudy days or evenings. Immediately after planting, they should be poured once. After 3 days, they should be poured once more. The survival rate can reach 100%. In winter, small sheds should be buckled for winter.
