1-4 months: still in the dormant period, the temperature is controlled between minus 5 and 5 °C, in case of premature germination, suffering from early spring cold damage. The potting soil remains moist and not sputum, so that the roots are normally dormant. Winter pruning is carried out before the eucalyptus fluid has not flowed from the end of March to the beginning of April. Plants that need to be replaced, small pots are replaced by large pots, the roots of the soil group have been removed, and some soils of the soil group have been cut, and some old roots have been cut off, and the soil is replaced with phosphorus and potassium fertilizer. Promote a new root and update the root system to 4? ? The germination of May has a good material basis. 4? ? May: In the upper and middle of April, the grape sap began to flow, and the winter buds developed leaves. Immediately combined with watering, the application of nitrogen-based thin mixed liquid fertilizer, anti-fat injury and young roots and shoots. When the winter buds are vigorously sucked, a fine germination work is carried out to erase the buds of the weak buds and the sprouting buds next to the shoots, in order to prevent the main buds from competing, which is unfavorable for the growth and development of the main shoots and the germination inflorescence. . 5? ? June: When the grape shoots are flowering the fruit, it is necessary to strengthen the management of water and fertilizer, watering once a day, and applying NPK mixed liquid fertilizer, or decomposed clarified liquid of cabbage and bean cake, every 10 days or so combined with watering, and Spray 0.2% borax water and 0.1% potassium dihydrogen phosphate on the foliage, each 2? ? 3 times, to stabilize the flowers and stabilize the fruit. When the fruit is large, leave 3 in the upper part of the ear? ? 4 leaves are topped and the re-emergence tip of the base of the fruit tip is removed. The vegetative shoots and extension branches of the unflowered fruit are also topped to eliminate all leaf bud growth points, and concentrate nutrients on the leaf area and the growth of the ears. At this time, it is necessary to prevent pests and diseases from harming the leaves and shoots. 7? ? August: It is the expansion period of the grape. In addition to the continuous supply of carbon nutrients, it also needs a lot of mineral nutrients. It is necessary to apply a thin liquid fertilizer based on nitrogen fertilizer every 7 days or so. Apply trace elements to promote the growth of fruit granules. Furthermore, at this time, it is in the dry season, the atmospheric humidity is small, and the foliar enamel has reached the maximum, and the leaf surface evaporation has increased. It is necessary to increase the number of watering in time. ? 3 times, the large basins are used once in the morning and evening, in order to prevent the dehydration of the potting soil and cause the fruit and leaves to compete with each other, resulting in the fruit particles not being able to expand normally, resulting in an abnormal phenomenon of large size of the fruit. 9? ? October: It is the ripening period of the grape coloring. At this time, in addition to watering 1 per day? ? 2 times, keep enough soil water to carry inorganic nutrients to supply the fruit coloring and maturity, and also add phosphorus and potassium as the main coloring and strong fruit fertilizer, while spraying the boron and magnesium fertilizer on the foliar to make the stem The starch stored in the leaves is rapidly converted to fructose and transported to the fruit to increase the sweetness of the grapes. At this time, it is forbidden to move into the indoor appreciation. It is necessary to place more sun on the balcony to enhance the vividness of the fruit. 11? ? December: It is the stage of the growth and aging of the winter buds of the grapes. After the trees are planted, the fertilizers and water should be controlled in time to prevent the buds of the tip of the shoots from sprouting. In case of tipping, it should be topped in time to inhibit the vegetative growth of winter shoots, forcing nutrients to concentrate on the growth and enrichment of winter buds and the roots of stem and leaf nutrients, so as to facilitate the reproduction of new roots and the robust growth of spring shoots in the next year. . Until the arrival of the big ice in December, it is necessary to control the water, and only keep the soil moist, so as to prevent the roots from being frozen. This point is more important in the north and south of the Yellow River; in the south of the Yangtze River, potted grapes are suitable for wintering on the balcony; in the northwest and northeastern cold regions, the south window ventilation of the living room can be moved, but the room temperature should be below 5 °C to prevent early hair.

As customers have higher and higher requirements for animal reproduction and animal disease diagnosis and treatment, traditional diagnostic methods such as visual inspection, stethoscope listening, thermometer inspection, and percussion and hammering can no longer meet the needs of animal husbandry production and veterinary clinics. Today, B-ultrasound is playing a big role in human medical diagnosis, and in the future, B-ultrasound will also play a role in animal medicine. We should promote the use of veterinary ultrasound scanner step by step according to the actual situation, popularize the knowledge of the use of veterinary ultrasound scanner, take this as an opportunity, and use it as a ladder to improve the level of veterinary practice in our country.
