Dahua Liudaomu is a very common shrub species in horticulture. The six-flowered wood is very beautiful, the branches are soft and drooping, and the flowers are full of white flowers, jade carvings and hail, crystal clear and extremely spectacular. How do you plant the big six flowers? What should you pay attention to when planting?
First, the planting method of Dahua Liudaomu
1. Substrate: The prepared matrix is ​​mainly composed of perlite and yellow sand with strong gas permeability and good water filtration. To increase the survival rate, a certain proportion of peat and grass ash can be added to it.
2, cuttings: collecting and processing in winter or early spring with mature branches cutting, can bloom in the same year; spring, summer, autumn with semi-mature branches or twigs cutting, and 1000ppm indole acid treatment of cuttings for 10 to 15 seconds, inserting trays Just fine.
3. Seedbed: The water content of the substrate before the rooting of the cuttings is maintained at 70% to 80%. After rooting, the substrate moisture content was reduced to 60%, reducing the number of sprays. At the same time, 0.2% to 0.3% urea and potassium dihydrogen phosphate were mixed with methyl thiophanate (or carbendazim) weekly and foliar sprayed.
4, refining: by controlling water, increasing light, ventilation and other measures to improve seedling resistance and external adaptability, will directly affect the survival rate.
Second, the big flower six road wood farming matters needing attention
There are three main reasons for the length of the six flowers: one is the reason of the variety itself; the other is that when the young tree is shaped, the big branches stay too little, or clumps, the side branches are less, the nutrients are too concentrated; or the strong branches are too heavy, The twigs are cut too much; the third is improper fertilization during the incubation period. During the sapling period, the application of nitrogen fertilizer, chemical fertilizer or large fat water, organic fertilizer is applied less; causing the branches to grow.
To prevent the growth of six flowers, you can take the following measures: First, cut off some of the main roots and long roots during transplanting, and promote the growth of lateral roots; Second, proper dense planting; Third, when pruning and shaping, it should be beaten in summer. The top is the main, the winter shear is supplemented; the fourth is the seedling that grows too prosperous, can control its length by cutting off the long main branch, the branches should be properly reserved, and the side branches should be left as flowering branches; the new shoots grow out Apparently, it can inhibit the growth of branches by spraying B-9, paclobutrazol, chlormequat and other growth regulators. Fifth, in the aspect of fertilization, it is necessary to increase the application of phosphorus and potassium fertilizer. After the new shoots have reached a certain length, it is necessary to pay attention to controlling the fertilizer and water. Drainage work is done during the rainy season.
