Several Kinds of Common Flower Shrub Vessel Cutting Technology

First, the preparation of the bed

The best choice for slotting is in a greenhouse or a well-ventilated open air. It is advisable to cut the soil in the north-south direction and level the soil on the plug bed, cover it around the inserting bed, make a low bed, the bottom of the low bed is 15~20cm below the ground, the bed width is 1m to 1.5m, and the bed length depends on the cutting amount. The earthworms made in the south are lower and higher in the north, mainly to increase the temperature and moisture. After leveling the inserter, disinfect with 0.5% potassium permanganate solution or 50% carbendazim 500 times.

Second, cutting matrix and container preparation

The cutting matrix was mixed in a ratio of 2:0.5:0.5 with the carbonized rice husk+sugar sand+garden soil. Disinfection of the cutting matrix can be done by formalin plus water 100 times solution. After spraying, mix the substrate well, put it on the heap, and cover the plastic film for 2 to 3 days to fully kill the bacteria in the matrix. Then remove the film, after 7 to 10 days, allow the matrix to taste after the Chinese medicine can be used. The cutting container can choose 9cm9cm non-woven container bag.

Third, the cutting method

From July to August, semi-lignified shoots were selected as cuttings in the year when they were robust, full, and free from pests and diseases. The length of the cuts of the lobular boxwood, the golden leaf privet, and the purple leaflet twigs is 6~10cm, and the upper 3~5 leaves are kept. The rest are erased, the rose can be left with no leaves or leaves, the cuts are flat, and the cuts are smooth. neat. For every 100 bundles, put them in the shade and wait. Moisturizing can be covered with wet sacks or wet sand. In order to increase the survival rate of cuttings, the roots of Ligenzhuang No. 1 powder can be selected. ABT can also be used for rooting powder. When using, firstly dissolve 1g root powder in 0.5kg alcohol (95%), add 0.5kg cold water, then mix 1kg 1000PPm stock solution. Then add water to dilute 10 to 20 times to treat the cuttings and quickly infiltrate the base of the cuttings for 5 to 10 seconds. The cuttings were inserted into a matrix-filled nutritional bag, and the depth of the cuttings was 2 to 4 cm. After the insertion, the solid substrate was manually pressed and the nutrition bags were placed in the insertion slot one by one. After the cutting is completed, drench the water once. Insert bamboo bows on both sides of the slotting machine. Generally, the height of the arch is 50~70cm, and every 80~100cm is an arch. The middle part is kept on a horizontal line, covered with plastic film, compacted with soil around, and bamboo curtain or 70% filter is set on the top. Shade nets are shaded.

Fourth, late management

After spraying, spray the leaves frequently to maintain the humidity. When the temperature is higher than 30°C, timely open the vents at both ends for ventilation and cooling. About 20 days or so after the cuttings can take root. At the end of October, shade shelters were gradually withdrawn. In November, depending on the cooling situation, a layer of plastic sheeting is placed on the outside of the film. The outer film is wider than the first shelf film (25cm) and is 30~40cm thicker than the first shelf film. Ensure that cuttings and seedlings safely pass winter. In the second year of March, check the humidity of the cutting bed and apply it once. Regularly check the degree of disease, insects, and grass damage, and spray pesticides in time. The growth of weeds and seedlings should be promptly removed in order to compete for water and fertilizer. As the temperature increases, more attention must be paid to ventilation and cooling. In April, the film was gradually removed and the seedlings gradually adapted to the external environment. Generally, the seedlings were cultivated for 7 to 10 days. After uncovering the film, besides controlling diseases, insects, and weeds, fertilization should also be paid attention. Fertilizer should be applied once every 15 days. The urea, potassium dihydrogen phosphate, and water should be formulated into a nutrient solution at a ratio of 1.5:1:2000. , 30 to 40 days topdressing a thin liquid fertilizer phlegm oil sauce.

After the "May 1st," the growth height of the container cutting seedlings can reach 20~30cm, and the container seedlings of the Chinese rose can be directly used for the greening project. After several months of nursery management, several other container seedlings were able to meet the standards of seedlings for engineering use during the summer.
