虞美人 cultivation management method :
After emergence, the seedlings should be planted. The row spacing of the planting plants is about 30 cm. When the leaves are 5-6 pieces, the water should be poured first, then transplanted. When moving, be careful not to hurt the roots, and bring the soil. Press tight. Usually do not need to water too much, often keep it moist. During the growth period, 5 times of water was used to digest the urine once every 2 to 3 weeks. Non-retained plants should be cut off with wilting flowers in the flowering stage to make the rest of the flowers bloom better. The maturity of the capsules is inconsistent and needs to be harvested in batches.
1. After planting and seeding, if not transplanted, the seedlings can be planted at a distance of 20 cm × 30 cm. The planting time should not be later than 110-120 days before the flowering date. To transplant, it is necessary to carry out on a cloudy day when the seedlings grow 3-4 leaves. Water should be poured before transplanting, and soil should be taken when seedlings are not damaged.
2. Light and temperature are cool, avoid high temperature, and it is best to grow in winter and cool in summer. Suitable growth temperature is 12 - 20 °C. As the temperature rises in summer, the growth of the beauty is weakened, and the ground part is dead with yellow. The growing period requires sufficient light and at least 4 hours of direct sunlight per day. If the growth environment is dark and the light is insufficient, the plants grow thin and the flowers are dim.
Fertilizer and water management: When planting, you should apply enough base fertilizer, and the soil that grows in the long-term growth period should be watered at the right time. Watering should master the principle of “see dry and wetâ€. When planting, control the watering to promote root growth. After the bud, sufficient water supply will be provided to keep the soil moist. Before the flowering, the thin liquid fertilizer should be applied 1-2 times. After the bud, the 0.1% potassium dihydrogen phosphate solution is sprayed once every 3 days, and the flower is stimulated. After flowering, cut off the withered flowers in time to make the rest of the flowers better.
Beauty is like sunshine, drought and drought tolerance, but it is not resistant to stagnant water. It should not be watered during the birth period to keep the soil moist. If it is not very dry, it does not need to be watered. But too much drought will delay flowering and affect quality. Fertilization should not be too much, otherwise the plants are long, too high and easy to fall. Generally, the land is deeply sown before sowing, and the base fertilizer is applied. Before the buds are flowered, one or two times of thin pancakes can be applied.
Pest control: There are few pests and diseases in the beauty, but if the nitrogen fertilizer is too much, the plant is too dense or continuous for many years, there will be rot disease, the diseased plants need to be cleaned up in time, and then some lime powder can be sprinkled in the original place. There are not many insect pests, but sometimes it is harmed by the larvae and scale insects of the chafer. If it is found to be sprayed with 40% omethoate 1000 times, it can be sprayed twice every 7 days to kill the insects.
The POLYKEN 980,955 is a multilayer system used for the protection of steel pipelines. POLYKEN 1019,1027, Liquid Adhesives can be used as primers for this system.In addition to serving as primers, these liquidadhesives themselves represent an anticorrosion layer and provide a uniformly smooth contact surface to promote high adhesion of the coating system to the pipe. They are designed for machine or brush application and formulated with stress-corrosion cracking inhibitors. The Anti-Corrosion layer POLYKEN 980 is engineered to assure a high bond to the primed surface with excellent conformability characteristics. The mechanical protection layer POLYKEN 955,achieves a complete bond to the POLYKEN 980 inner layer, providing maximum handling and in-service protection for the coating system. The adhesives in these and all POLYKEN tape systems contain proven anti-microbial additives.The POLYKEN 980/955 can also be used for ductile iron pipes, in this case the use of 1027 primer is recommended.
