The Foxhorn tiger ear is a semi-evergreen shrub of the species Rattus punctatus, with green leaves in spring, summer and autumn, and late fall and winter orange leaves turn bright red. Branches arched, branchlets drooping, racemes racemes terminal, honey scent. Because of the beautiful tree shape, white flowers and green background, red leaves in autumn and winter, it is an excellent plant and basic planting material for garden color blocks and hedgerows. As the introducer of this variety, Xu Shaoyuan, the technical director of Zhejiang Senxi Company, introduced the key points of his production during an interview with the reporter.
Reporter: There are several types of product seedlings for Ferson Tiger's ear.
Xu Shaoyuan: There are mainly four types of plug seedlings, net bag seedlings, color seedlings, and hedgerow seedlings. The former two require seedling height above 5 cm or shoot length above 5 cm, complete root system, robust plants, no pests and diseases. The color of the seedlings is 30 cm in height, more than 3 branches in one level, the height of the branch points is less than 10 cm, and the container size is 10 cm and 10 cm. The hedgerow is 60 cm high and has a crown of 40 cm. The heights of the first, second and third branch points are respectively below 10, 20 and 30 cm, and the crown shape is uniform. The container size is 1 gallon.
Reporter: What are the requirements for soil quality when cutting seedlings are transplanted into Daejeon?
Xu Shaoyuan: The soil must be loose, fertile, and slightly acidic. If the clay is heavy, compacted, and has poor air permeability, it must be improved.
Reporter: How to improve?
Xu Shaoyuan: Soil plowing, more than 25 cm deep, leaving no dead ends, and then fine. Before deep plowing for the first time, 3,000 kilograms of manure or 30 bags of organic fertilizer were applied per acre, and they were turned into the soil by deep plowing.
Reporter: When was transplanted, how many rows were suitable? What to pay attention to?
Xu Shaoyuan: Transplanting can be carried out from the beginning of November to the following April. Plant spacing 35 cm, spacing 40 cm, 3,000 per mu. If it is container seedlings, plug seedlings or net bag seedlings, the soil ball should be kept intact during transplanting; bare root seedlings should be properly trimmed to the root system. The transplanting was slightly deeper than the original plant, and was piled with fine soil at the root and the roots were stretched with yellow soil. Then compaction, keeping the transplanting seedlings in order, timely watering the rooting water. Finally in the bed straw, moisturize and prevent the growth of weeds.
Reporter: What are the points in the management of the Fussen Huer transplanted seedlings? Spike how to operate?
Xu Shaoyuan: Watering the seedlings in time, in case of continuous sunny days, watering on the 4th day after transplanting, and pouring once every 10 days. Drain water on a continuous rainy day and no water accumulates in the trails. Transplanting should be shaded at the beginning and fully illuminated after survival. When the ear is harvested, a shade net should be installed to keep the cutting strips from losing water. When spreading urea and compound fertilizers, they are first sprinkled on the topsoil and then combined with weeds and loose soil to turn the granular fertilizers into the soil. Sprinkle between the rows so as not to damage the stems, branches and leaves of the seedlings. Immediately after the ear was harvested, fertilize the seedlings on the ground.
Diseases mainly have blight, control methods include: removal of diseased branches, concentrated burning; control of density, so that the seedlings are airy and transparent; at the beginning of the disease, it can spray Guoguanggen rot or clear soil fungicide 400 to 500 times liquid or 50% gram bacteria Dan 800 times, once a week, spray 2 to 3 times.
Land planting is to cultivate the scion nursery. Shearing twice a year, in late May and September. The mother's first cutting height of 10 cm, the second 20 cm.
Reporter: What are the preparatory tasks for the Fusson Tiger Ears?
Xu Shaoyuan: The use of ground seedbeds, plus a shading rate of 65% shading nets. The matrix formulation was vermiculite:peat:perlite:fine sand=5:3:1:1 (volume ratio), and 100 grams of cockerson was added per cubic meter. The mixture was evenly mixed. The plug size is 72 holes, 27545.5 cm (deep), and the plug tray is filled to ensure that the tightness of each hole is the same.
The filled trays were placed in turn on a seedbed and 0.5% potassium permanganate solution was used to sterilize the trays filled with the matrix. Complete this work 24 hours before cutting.
Reporter: When did the cuttings need to be done?
Xu Shaoyuan: May and September can be cut. Spike length 3.5 cm, cut into one leaf and one bud, the big leaves retain half, all or most of the small leaves remain. The top of the cuttings was trimmed at the top of the leaf bud by 3 mm to prevent damage to the shoots. The root of the cuttings was placed in a rooting agent at a speed of 1 to 1.5 cm for 2 seconds. After the sunny day, wait for 3 hours and rainy days for 6 hours to make the rooting agent more effective. 72 holes were used for cutting and cutting, 6 per square meter, a total of 432 strains.
Cutting depth from 1 cm to 1.5 cm. Immediately after the plug, water is irrigated and the leaves are sprayed with 1000-fold carbendazim and anthrax-Fumei mixture. Then the small arch shed is covered with a plastic film and sealed around.
Reporter: How to manage postcuts? What diseases need to be controlled?
Xu Shaoyuan: One week after cutting, check the seedbed on a rainy day or on a sunny day. The moisture content of the substrate is 60% to 70% of the saturated moisture content, and the relative humidity of the air is above 95%. After cutting in a monolithic greenhouse, the summer and autumn days are sunny and the temperature in the shed is controlled below 36°C. Before hair rooting and germination, the shading rate is basically 75% to 90%.
The disease is mainly anthrax and root rot. Generally, anthrax and carbendazim are sprayed and controlled every 20 days, and the diseased plants are burned in time. When basic cutting, basic fertilizer is not used. After spraying for 10 days, water-soluble fertilizer with foliar fertilizer (eg 0.1% urea) was sprayed when spraying with water, promoting cutting roots faster. Spray fertilizer once every 10 days. About 25 days after cutting, the rooting rate can reach more than 90% and enter the training stage. When there are more than 90% of hair roots, you can uncover the two films on the roof of the small arch. After two days, you can remove all the films. After starting the training, one layer of shade net can be peeled off, and after the basic ones have already been pumped up, the remaining shade nets are removed and full illumination is performed.
