First, moisture management The soil moisture after planting was maintained at 70%-80% of the maximum water capacity in the field. In the hot season after planting, water is poured every 4 to 7 days under normal soil conditions. Water is poured every 7 to 10 days in early spring and autumn. Prolong the watering interval properly in low wetlands. Watering is generally performed in the early morning and ridge cultivation is performed in the early evening. Second, temperature management The indoor temperature of the shed is maintained at 25 to 30°C and the night temperature is 14 to 16°C. When the outside minimum temperature is stable at 12°C or above, it can be ventilated overnight. Prevent high temperatures exceeding 35°C. Third, lighting management To ensure that the temperature is not too high, try to increase the light intensity. When shaded by a sunshade net, when the temperature at the top of the plants in the sunny shed room rises to 30°C, the sunshade net is set in a position where the sun shines directly, and it is promptly retracted after cooling. Fourth, fertilization management When the first fruit is sitting and begins to expand, it is combined with watering and fertilizing. After each ear fruit is topdressed once or once every 10 days, each fertilizer is topped with 8 to 10 kg/mu. During the fruit expansion stage, 30 to 50 kg of compound fertilizer containing nitrogen, phosphorus, and potassium in a ratio of 1:1:1 is applied to the fruit during the fruit enlargement period, and potassium can be topdressed during fruit coloring to maturity (the ratio of nitrogen, phosphorus and potassium is 1 1:1:2) 5 to 10 kg/mu, topdressing can be applied, and can also be applied with water, and at the same time pay attention to appropriate amount of calcium, magnesium, boron, zinc, molybdenum and other nutrients, can adopt foliar spray, etc. Way to apply. Fifth, plant adjustment The following pruning methods can be selected based on the length of planting days and the height of the shed: 1. Single dry pruning Use four panicles to six panicles. 2. Single dry head replacement The three panicles are changed head and head and pruning method is repeated. The main stem is changed several times after each fruit of the three panicles. Five panicles and three panicles are changed head and pruning several times. After the main branch of the five panicles, the heads are replaced, and then each knot is 2 to 3 ear fruit for the first time; two panicles for the first time for the whole pruning method, the main branches of each fruit after the second, for several times to change head. 3 double dry head pruning Use five panicles and four panicles to change the head and pruning multiple times. 4. Snoring to the old leaves When the lateral buds grow to 7 cm to 10 cm, remove them. Grasshoppers are carried out after sunny leaves without dew. For old leaves and yellow leaves that grow below the ear of the lowest position, they are removed in time. 5. Hanging vines After the first spike blossoms, hang the vines with slings. For pruning the head several times, after the fruit has been picked (3 to 5 spikes), the vine is dropped. Place the ridges under the ridges and ground them, and then change them again. The fall should be done in the afternoon. After each spike, the fruit was hung on the vine with a rope. Six, preserved fruit 1. Flower protection When temperature below 15°C or high temperature above 30°C appears, growth regulators should be used to decorate, wipe and spray flowers. Use Shennong No. 2 and anti-dropping agents to spray or decorate flowers, and use appropriate concentrations according to the temperature at that time. 2. Thinning and fruit thinning When flowering, select 6 to 7 flowers per panicle, and discard the rest. After fruiting, if the fruit set is too large, remove the first fruit and the end of small fruit and deformed fruit, choose to leave 4 to 5 good fruit. The location and strength of the strong light can keep more fruit, and vice versa. When using "Bai Li" varieties, the average fruit per ear was 4.
Hyaluronic acid is an acidic mucopolysaccharide, which was first isolated from bovine vitreous in 1934 by Meyer, Professor of Ophthalmology at Columbia University. With its unique molecular structure and physicochemical properties, hyaluronic acid shows a variety of important physiological functions in the body, such as lubricating joints, regulating the permeability of blood vessel wall, regulating the diffusion and operation of protein, water and electrolyte, promoting wound healing and so on.
