The thicker annual weeds are inserted directly into the basin. If the seeding rate is not enough, the pruned waste can be reused. Moreover, the price of good varieties of grass seed is higher, which can reduce the cost. Rapid propagation of cuttings greatly shortens the growth cycle, reduces production processes, and saves manpower and material resources. The annual grass varieties that can be cut include red string, marigold, peacock grass, carnation, periwinkle, and beautiful cherry. In the production practice, the author explores the rapid propagation technology of cuttings. The following is briefly described as follows:
First, basin soil selection Culture soil in accordance with potted flower culture soil requirements, one should be loose, and second, moisture permeability is good, three must be able to maintain water and nutrients; four to moderate acid and alkali, five to be sterilized and disinfected. The author will store four to five years of garbage soil, mixed with a certain amount of sand or river mud, after drug disinfection as a culture soil. Generally should not be mixed with organic fertilizer, so as not to burn cuttings.
Second, the cutting time in summer and autumn, the temperature of 20 °C to 32 °C, in the afternoon is appropriate, it is best cloudy days.
Third, the choice of cutting standard selection of robust, pest-free shoots as cuttings, each cutting 8 to 10 cm long, with more than two sections, the top may leave leaves as appropriate. The leaves of the top of the marigold tree can all be left. A string of red can leave more leaves without affecting the shape of the plant. However, all the leaves on the branches under the soil should be removed and the cut should be smooth.
Fourth, liquid treatment
After mixing 2.5% to 5% rooting agent with 50% carbendazim wettable powder 800 times, immerse half of the cuttings in the liquid for 5 to 10 seconds. Marigold twigs do not require rooting agents and carbendazim when cutting branches, and the survival rate can reach 95% or more.
5. Cutting requirements Cutting inserts shall be inserted along with the cut and dip inserted into the soil, leaving the main branch leaves and part of the lateral branches above, inserted in the center of the flower pot, and immediately watered after being planted and sprayed with water.
Six, post-insertion management
1. After shading, put it under the shade of a shed, and maintain it for 7 to 10 days. After rooting, put it in an open space. Among them, marigolds are thicker and more robust, and the rooting rate can reach 90% or more under full illumination. A string of red roots are better under relatively shady conditions, and it is easier to root in woods with a canopy density of 0.7 to 0.8. Other varieties are placed under shading.
2. Spray Because the weather is hotter when the pot is inserted into the pot, the number of water sprays per day is not less than twice or even 3 to 5 times. The leaves are not wilting and the basin soil is moist. After 7 to 10 days, the branches and leaves are still green, and the two fingers are used to gently lift the seedlings. The bottom of the branches is not stained, indicating that the cuttings have taken root. Spraying can be stopped, and watering can be performed in order to avoid the shading conditions. The next leggy.
3. After growing a certain period of time, the top-dressing seedlings have grown more young leaves and can be sprayed with foliar fertilizer. With 0.5% urea and potassium dihydrogen phosphate spray, cake water can also be poured.
4. Insect prevention and weed control prevents spider mites, moths, and snails from killing weeds in time. Seedlings grow in time to increase the spacing.
