The baby food is a compact, small-sized Chinese cabbage, which is thin, sweet, tender and delicious. It is welcomed by the market because of its small edible rate. In recent years, with the large-scale promotion and cultivation of plastic arch greenhouse vegetables in the Suzhou area, plastic canopies have been used to grow baby food and have achieved good economic benefits. The cultivation techniques are summarized as follows:

First, use fine varieties

Selection of Beijing Academy of Agricultural Sciences, bred from the center of green leaves, light yellow leaves, small plant type, fast ball speed, good quality, anti-virus, downy mildew and soft rot, Jingchun dolls resistant to twitching dish.

Second, the formation of land qiao base fertilizer

In the autumn of last year, the former rickets and weeds were removed in a concentrated manner. In combination with deep ploughing, the Mushi quality farmyard fertilizer was 4 square meters, and the superphosphate 50 kg. The pressure was flattened. The pond was 30 cm long, the dry pond was 50 cm long, and the ridge height was high. 15 cm, ridging and filling with winter water.

Third, timely sheds to raise the temperature

At the end of February of the following year, the weather was selected to be warm until the surface was thawed. After the thawing on the surface, the film was covered on the ridge surface and sowing was awaited.

Fourth, appropriate early planting and reasonable close planting

In early March, according to the spacing of 18 centimeters, "T-shaped" broken film on demand, sowing 5 to 6 per hole, acres with 150 to 200 grams.

V. Strengthening field management

1. Temperature management: Appropriately increase the temperature of the greenhouse before emergence to facilitate seedling emergence; pay attention to ventilation and cooling after emergence; daytime temperature should be controlled at about 25°C, and keep at 10°C～12°C during the night. As the temperature rises, the ventilation volume is gradually increased. When the minimum temperature in the outside world rises above 15°C, remove the film. Membrane cultivating and weeding after removing the film to increase the temperature and promote root development. During this period, the seedlings should be planted 1 or 2 times, leave 2 to 4 plants per hole for the second leaf and one heart, and set 3 to 4 leaves of the true leaf, leaving 1 plant per hole.

2 water and fertilizer management: Rosette appropriate control of water and fertilizer, not big floods and big fertilizers. The core period should be poured with small water to meet the water supply and prevent the plants from becoming leggy, so as to avoid the diseases caused by the high density of the air and the humidity. Top dressing is carried out in two stages. During the rosette period, 10 kg of urea is applied per acre, and 10 kg of diammonium phosphate is sprinkled in the ditch, followed by watering. After entering the ball period, each mus will be topped with 20 kg of compound fertilizer. During the growth, the leaves were sprayed with fertilizer three times and sprayed with 0.3% potassium dihydrogen phosphate plus 0.2% urea. Stop watering the week before harvest.

Six, timely harvest

In the middle and late May, the vertical diameter of the baby food is about 15 cm, the maximum diameter is 7 cm, and the middle is slightly thicker. When the single ball weight is 150-300 grams, it should be harvested in time (the weight of the whole doll dish is about 800 grams), otherwise The leaf ball is too big or too tight and loses the value of the goods. At the same time, it is easy to cause convulsions and leaf ball rot.

Reversed Phase Chromatography Resins

Reverse phase chromatography (RPC) resins are important alternatives to silica-based RPC media as they have different selectivity, high capacity and wide pH stability range. UniPS®, UniPMN, and UniPMM are the major components of NanoMicro Tech`s polymeric RPC bulk media product lines. All of them are monodispersed, rigid divinylbenzene or methacrylic copolymer beads developed with proprietary precision microsphere technologies. They are designed for high resolution and high capacity RPC purification of a wide range of materials, from natural products, peptides, oligonucleotides to large proteins.
