The new high-yield and high-quality cold-resistant leeks--the winter leeks have the advantages of high yield, high quality, stable yield, disease resistance and strong resistance. The winter solstice leeks are erect, grow fast, have strong tillering power, less coarse fiber, spicy and spicy, dark green leaves, 1 cm wide, up to 2 cm wide, 40 g single, 60 cm above plant height, annual harvest 10éŸ-11茬 of leeks, about 12,000 kilograms of amaranth per mu. This variety is particularly resistant to cold, and does not look back in winter, and does not sleep. In the cold snowy days, the plants did not wither. In December of that year, the winter solstice greeted the green leaves and grew slowly. The variety was known as the “winter solsticeâ€. In the spring of the next year, it will be early, and it will be about 20 days in the morning than other varieties.
The winter solstice amaranth is suitable for cultivation in open and protected areas in southern China, North China, East China, Central China, Northwest China, Northeast China, etc. It is an excellent new variety for the production of leeks in winter and spring.
Technical points for cultivation management of winter leeks
1. Before applying soil preparation and fertilization, apply 3 square meters of agricultural livestock and poultry manure per mu, 50 kg of urea or compound fertilizer, preferably the three elements of nitrogen, phosphorus and potassium are applied. Then plow the arable land and then snoring, the width of the squat can be determined according to the needs.
2, the seeding point of seeding amount of 1 kg per mu of exposed land, protected land (green shed) 3 kg -4 kg per mu. Soak seeds before sowing, use tea pots or other pottery and tools for soaking seeds. Soak in warm water or cold water at 20 ° C - 25 ° C for 6 hours to 8 hours, then control the water. The field can then be sown, and the method of sowing can be carried out by a straight or triangular method with a plant spacing of 5 cm to 10 cm and a row spacing of 30 cm. Cover the fine wet soil of 1 cm - 2 cm in time after sowing, keep the ground moist, about 10 days - 15 days, the seedlings can be released. March-May is the live broadcast time of Daejeon.
3, field management seedlings pay attention to weeds and topdressing. The variety absorbs a large amount of water and fertilizer, and should be watered and fertilized. When the leeks grow to 10 cm to 15 cm, apply 20 kg of compound fertilizer or urea per acre, and then water. Fertilization can be carried out simultaneously with watering, and the fertilizer is directly scattered into the field. When the seedling grows to 25 cm - 35 cm (ie 4 pieces - 5 leaves), it is necessary to use large water and large fertilizer, apply compound fertilizer or urea 25 kg per mu, keep cutting a leek and apply two fertilizers, and pour twice water. In the same year, the plant can cut 1 knife and 2 knife, and every 30 days to 35 days after the second year. Water is poured 10 days before the winter to ensure that the leek is safe for winter.
The purpose of the rotary evaporator rotovap is to remove low boiling organic chemicals, usually solvents, from a mixture of compounds .
The rotary evaporator always for distillation and extraction under vacuum pressure . The motor runs the rotation flask moving and heating water oil bath pass hot energy to the mixture of rotary flask . Then low boiling point of mixture will be heated and form a thin film and make evaporation . The lower boiling point mixture make morphological change from liquid to Vapor or hot air . Then hot vapor meet condenser cooling coil then become liquid again and fall down to collection flask .
