2. Promote the renewal of the stratum corneum raw materials: these raw materials can promote the metabolism of the stratum corneum of the skin surface, remove the surface of the pigmentation spots, so that the skin becomes smooth and delicate. Common fruit acids, salicylic acid, etc..
3. Antioxidant raw materials: these raw materials can resist the attack of free radicals, prevent the formation of melanin, protect the skin from oxidative damage, so as to achieve the effect of whitening spots. Commonly, there are vitamin E, green tea extract and so on.
4. Raw materials to block melanin transmission: these raw materials can prevent melanin from basal layer to surface layer transmission, thus reducing pigmentation and achieving the effect of whitening and eliminating spots. The common ones are aloe vera extract and peony extract.
5. Skin repairing raw materials: these raw materials mainly help to repair damaged skin and promote the skin's self-repairing ability, so as to reduce the formation of pigmentation. Common hyaluronic acid, collagen and so on.
6. sunscreen raw materials: these raw materials can block ultraviolet damage to the skin, to prevent the formation of melanin, to achieve the effect of whitening spots. Commonly, there are titanium dioxide, zinc oxide and so on.
Potted Pomegranate Technology
Potted pomegranate has both ornamental value and fruit harvesting. Larger sites, houses, and balconies can be cultivated. When it was partially flowered in the autumn, it can be flowered in the second year. 1 Seedlings of nursery plants of superior quality can be used for potting. Small pots can also be used to breed seedlings. Cut pruned pomegranate twigs into about 20cm, and in March and April, insert 20cm in nutritious soil pots and insert 1 to 2 pots. Watering in a timely manner after plugging in, keeping the basin soil moist, applying organic fertilizer solution for 2 to 3 times during the summer to promote growth, and cultivating strong seedlings can be used as potted seedlings in the autumn. 2 pots and nutritious soil potted pomegranate pots can be used tile pots, pots, plastic pots and so on. The caliber is generally more than 30cm, and the volume of the basin is generally more than 5L. Nutritious soil available 1 3 legume compost soil compost + 1 3 garden soil + 1 3 sand soil, plus 1kg 25% N, P and K compound fertilizer per m 3 of nutrient soil and mix well. 3 Planting and planting time is usually carried out in the dormant period of deciduous. Put a few pieces of broken tile on the water seepage hole at the bottom of the selected pot, and then put some nutritious soil, put the seedlings on the nutrient soil, and the root system will be added after the nutrient soil is added. Gently tap the edge of the basin, lightly compact the nutrient soil, leave a few centimeters deep in the basin to fill the soil, fill the basin and pour the water once. After a period of time, add some nutrient soil after basin sinking. 4 Water and fertilizer management Although pomegranate is drought-resistant, it cannot be prolonged drought. In the spring and autumn sunny days, water is poured once in 1 to 2 days, and in summer, water is poured 1 to 2 times a day. In the winter, according to the basin soil drought, some water should be poured in time. Long-term rain during growth should pay attention to the basin of water. After fertilization, fertilization begins. Fertilizers such as bean cakes and other organic fertilizers are generally used for fertilizer application. Remove the fertilizer solution more than 10 times after the water applied in the basin, generally 7 to 10 days of fertilization once, can be applied before flowering a 0.3% urea solution to promote flowering fruit. During the fruit enlargement period, 0.3% potassium dihydrogen phosphate solution can be sprayed twice, which is beneficial to fruit growth and growth. 5 Flower and Fruit Management 5.1 The amount of pomegranate in the thinning and thinning fruit is large, and flowering gradually after May. In addition, pomegranate bell-shaped flowers can not be fruit set, only a part of the barrel-like flowers can be fruit set. Therefore, in addition to the need for viewing during flowering, timely sparse bell buds and dense buds should be removed. In addition, the fruit of the pomegranate seedlings and the two-conservation flower seedlings are strong, so it is necessary to keep the fruit set firm, and the three-barreled flower must be removed in time if it is not watched. After the fruit is set, the fruit is left to leave more fruits, and the fruit is selected to leave two. The three pods, such as the head lice and the second pods, can retain some of the fruit and leave the rest. 5.2 Preserving fruit and flower During artificial flowering, the fruit set can be improved. The freshly-spread pollen is applied to the tip of the brush with a brush, and then it is placed on the newly opened barrel-like style head. Foliar spray of 40 ~ 50mg L gibberellin or spray 20 ~ 50mg L naphthalene acetic acid can also increase the rate of fruit set. Taking shelter from rain during flowering can also increase the rate of fruit set. Do not pour water on flowers during flowering. 6 plastic pruning 6.1 The shape of the pomegranate tree should be single-dried. The height of the stem is about 20-30cm. The leading stem has about 5 main branches, and the main branch has branches and branches. 6.2 Pruning the pomegranate in winter is more likely to be dominated by thinning. The main branch extension branch or branch of the culture branch group should be short. Mixed buds of pomegranate are planted on top of or near the top of a robust twig. Be careful to keep it. Branches with sparse branches can be short and long branches, leaving 2 to 3 buds for new shoots. 6.3 In the summer, the pomegranate buds are precociously cultivated. During the growth period, the pruning buds can be repeatedly planted and the branches of the crown gradually become denser. Therefore, the useless buds and young shoots should be wiped out during the growth period, and the dense branches should be neglected. Long toppings can promote stoutness. 7 Diseases and Insect Pests Potted Pomegranates Common pests include aphids, moths, and scale insects. Aphids can be washed with 0.4% detergent or use predators to prey on aphids. The moth larvae were sprayed with a 3,000-fold enemy killing liquid to kill or artificially kill the larvae. Turtle wax scale insects can be treated in the dormant period or sprayed with 800 times 50% dichlorvos for control during the summer egg incubation period. 8 The long-term growth of the pomegranate in pots for changing pots and changing soils will gradually weaken, and the larger pots generally need to be replaced in 2 to 3 years. After removing the pomegranate root from the pot, remove the root pad and a small part of the root system, put the nutritious soil into the new pot, add the soil pomegranate into the nutrient soil. Do not change the basin potted pomegranate but also pull out the soil, remove the root pad and a small part of the root system replaced with a new nutrient soil, pouring enough water. 9 Overwintering potted fruits and pomegranates should be kept cold in winter and can be placed indoors or in sheds for winter. In winter, it is not too cold in areas where winter can be exposed. Generally, some smashed grasses are covered on the potted soil to protect the roots and necks. Before the arrival of the cold current, the basin soil should be checked for dryness and humidity. The basin soil should be poured once to dry.
