Non-pollution-enhanced Cultivation Techniques for Strawberry in Greenhouse

1 Cultivate disease-free strong seedlings
1.1 Choosing appropriate varieties of greenhouses to promote cultivation should use early flower bud differentiation, shallow dormancy, cold-resistant, high yield, high quality varieties, the current production mainly include Fengxiang, Mingbao, ghost anger Gan, Zhangmu girl, Xing Xiang, Zhang Ji and so on.
1.2 Establish special nursery nursery
1.2.1 In the nursery preparation and propagation garden, the plot with loose soil, high topography, good drainage and irrigation conditions, and sunny leeward should be selected. The sandy loam soil that requires no soil drying, no compaction, no accumulation of water, no heavy crops, and no pests and diseases. Leave the seedbed in a 1:4 ratio. Former crops for strawberries or vegetables should be chemically soil-sterilized or solar-sterilized.
1.2.2 The best choice for planting mother plants is the use of tissue-cultured virus-free seedlings. The virus-free seedlings have a strong growth potential and strong disease resistance. Strawberries can fully demonstrate their variety characteristics, good quality, high yield, and generally better than non-virus-free. Increase seedlings by 15% -30%. At the same time, attention should be paid to the selection of the best fittest. In the previous year, reserve healthy and disease-free plants as the second year of early spring breeding seedlings or in the late fruit field to remove weak seedlings, select the best strains, and draw the seedlings. Timely elimination of mixed and degraded seedlings in production.
The spacing of mother plants should be determined according to the variety characteristics, planting period, and cultivation conditions. For varieties with strong stolonability, larger plant spacing can be used, the mother plant is planted early, the fertilizer and water conditions are better, and the cultivation and management are fine. For more stems, larger row spacing should also be used. Mingbao, Fengxiang and other varieties, each parent needs nutrition area of ​​1-1.2 square meters, and Zhangmu girl, Fortunate fragrance, Zhang Ji and other varieties, each parent strain needs nutrition area of ​​0.5 square meters. In general, 800-1200 strains of excellent mother plants are planted every 666.7 square meters, and a plant of 1.5-meter wide planters is planted in the center, with a plant spacing of about 40-60 cm. 50cm from the ditch each plant a plant spacing 50-80cm.
Mother plants are usually planted from late February to early April to extend the breeding period. When planting, the old leaves and leaves of the mother plant should be removed. Demands are not buried deep and shallow. The depth of planting leaves the base of the heart and the top of the root neck to be level with the soil surface. When planted, it should be solidified by watering in a timely manner after planting. After the normal survival, the plastic film is removed in mid-late April.
1.3 Management of nursery nursery
1.3.1 Soil Fertility Management After the planting, the soil must be loosened in time to create loose and moist soil conditions for the seedlings to take root. Avoid high-nitrogen flooding to prevent seedling growth, flower bud differentiation and disease occurrence. In the case of applying basal fertilizer, it is generally not necessary to top-dress. If the plant growth is weak, it can be combined with loose soil watering. When drought 5-7d, pour a little water or light irrigation, do not flood irrigation. To combine weeding often shallow cultivator, rainy days or large water should be promptly drained. If the fertilizer is insufficient, it can be applied 2-3 times during the stem growth period, and no more than 10-15kg of ternary compound fertilizer per 666.7 square meters, or combined with loose ten feculent rot and fecal water.
1.3.2 Management of mother plants and stolons
1.3.2.1 Removal of flower buds: In the spring of planting mother plants, care should be taken to remove the buds that appear on the mother plant in a timely manner, reduce nutrient consumption, promote hairy stems, and form robust strains.
1.3.2.2 Arrangement of vines: Mother plants planted in sheds should be controlled for conditions such as temperature inside the shed, and the pods should be often tidyed and fixed. When the pods cross each other and fall to the ground, they can be led to empty spaces. In the stalks of the stolons, press the stems with soil, or use grass stalks, arched wire, etc., to keep the spacing between the sub-plants 10-15cm. After enough seedlings are removed, the mother seedlings and the post-embryo shootlets are removed to achieve ventilation between the plants. Transmit light to ensure that each plant has enough nutrient area.
1.3.2.3 spraying gibberellin: 0.3-0.5g gibberellin powder (one gram a small bag of 2-3 copies), dissolved with a little alcohol, add water 10kg, 5-10ml per dilution. Foliar spraying.
1.3.2.4 Chemical and artificial weeding: Combine crushed stubble before planting, uniformly spray 48% trifluralin EC 150-200ml every 666.7 square meters, and loosen the soil immediately after application of drought to prevent grasses etc. The annual weed sprouts. During the 2-3 leaf stage of monocotyledonous weeds during growth, they are controlled by Ganoderma lucidum, Gramineae, and so on. And arrange the vines to make them evenly distributed. The clods press the stems to promote rooting.
1.3.2.5 Removal of old-leaved leaves: Regular removal of senescent and diseased leaves, maintenance of 4-5 green leaves and stalked shoots of mother plants, and promotion of seedling growth.
1.3.2.6 Insect pest control: If the underground pests occur in the pre-growth stage and the late growth stage, they can be poured 1500-fold or 90% crystal trichlorfon 800-fold solution, or 90% crystal trichlorfon or phoximine emulsion 150 - 200g stir-fry and stir-fry 10kg in the evening. Foliar insect pests were selected from farmland music, bitteractone, aweichuangqing, custodiacetin, and kashanke, etc., and the disease was selected from the group consisting of polyoxo-qing, thiophanate-methyl, chlorothalonil, and acetochlor. Appropriate concentration control.
1.4 Root-cut transplantation
1.4.1 Picking Seedlings for Implantation For root-cutting seedling transplants, attention should be paid first to the early planting of seedlings, usually from late June to late July. Collect seedlings and shoots (stemmedium seedlings), collect pure and vigorously growing seedlings in nursery nursery, retain 3 leaves, cut about 3cm of stalks near the end of mother, remove old leaves, diseased leaves and other stolons. Separate small and large seedlings and put them in plastic pots filled with water, dip only roots, prepare for planting, and choose to build false phytostils without disease. The planted worms are generally 20-25cm high, 80cm wide, and 5 lines each. The distance between the lines is 10-15cm15cm. During planting, the large seedlings exposed the remaining stem sections, and the young seedlings inserted the stem sections into the soil and were separately planted. After the implantation is completed, the bed is covered with cold yarn, and water is sprayed on it. Afterwards, it is necessary to pay attention to spraying water frequently in the evening to maintain the humidity. After 10 days or so, the cold yarn can be removed, and the underground pests such as earthworms are prevented from damaging the root system of the seedlings. The false plantlets should be transplanted and cut off during the induction of flower bud differentiation.
1.4.2 Transplantation of cuttings The period of root-to-root transplantation is usually performed 20 days before the flower buds are scheduled to form. It can be carried out in the middle or late August. The medium-sized and medium-sized seedlings (4-5 green leaves and 0.6-1.0 cm thick root neck) are used to plant seedlings. A small shovel cuts the roots in a nursery and cuts it into a square or cylindrical shape. The side length or diameter is about 7 cm. The planter is transplanted with a plant spacing and the transplanted seedlings are filled and flattened. On the day before the rooting of the transplant, the water was irrigated so as to facilitate the transplanting of the soil and a temporary wilting occurred. This is a normal phenomenon.
The number of transplanted root cuttings depends on the plant flower bud differentiation status and growth trend, generally 1-2 times, appropriate early transplant root-cutting period, strong nutrient growth, a large number of flower buds, root cutting after flower bud differentiation, less flower bud differentiation, and unfavorable to flower bud development .

Thread Lift including Korean Thread Face Lift,Gold Thread Face Lift,Thread Lift Face.

MAGIK Lift Series are made of PDO ( Polydioxanone ), it is a thread with no cones, thus no damage to the tissue. We call it Face Lifting Thread /Face Lift Threading. This is the same thread used in Cardiac and other surgeries as sutures, and thus it is very safe.

Aging causes the skin tissue to be thin because the collagen and elastin fiber is break down, which results in sagging skin, deep creases, folds and wrinkles. Magik thread reverses the effects of aging.
Threads are implanted into the sub-dermal skin and stimulate the production of collagen and the skin becomes firmer, elastic and moisturised. The thread dissolves itself in couple of months but the effect last for 12-18 months.
