Eggplant Grafting and Controlling Nematode Technology in Solar Greenhouse

In the greenhouse, the use of fine eggplant varieties for scion, wild eggplant for rootstock grafting cultivation, is the most effective and successful technical measures for the control of root knot nematodes. Specific techniques are as follows. 1. Variety selection Rootstocks should be wild eggplant varieties with high resistance or immunity to root-knot nematodes, such as Korean CRP and Japanese Toru-ba mother. Since Toruruba's resistance to nematode was stronger than that of CRP, it was better to use Torlubaca for rootstock varieties. Scion varieties can be selected from local excellent eggplant varieties, and there are new dragons, britas, and arrows in the Shouguang region. Second, nurturing strong seedlings 1. Select the appropriate sowing date. Since eggplant is produced in protective facilities after grafting, grafted eggplant can be sown at any time of the year. The principle of scheduling sowing is to arrange the time for the product's pick-up and listing to be in a time when other production methods are not easily listed. 2. Soak germination. Place CRP or Toruruba in warm water at 55-60°C, stir until the water temperature is 30°C, then soak for 2 hours, remove the seeds, and air dry for 24 hours at 100-200 mg/L in gibberellin solution. After germination, when the bud grows to 1 to 2 mm, sowing. Eggplant scion only soaking does not germination, soaking methods: soaking with 1% potassium permanganate solution for 30 minutes, remove the panning clean; then soaking in warm water at 55 °C, water 5 times the seed, soak for 15 minutes, and then Soak in warm water of 25°C for 8-12 hours, then use the fine sand mash to remove the mucus on the seed coat, wash it, dry it, dry it and let it dry. In order to achieve a suitable grafting age, the scion should be soaked again when the rootstock is primed. That is, the scion should be sown 15 to 25 days later than the rootstock. 3. Transplanting. When rootstocks and scions are grown to two leaves, they should all be transplanted into the nutrient bowl. When transplanting, it should be thoroughly irrigated with bottom water and properly shaded after transplanting to speed up its slow seedling growth. 4. Grafting. When the rootstock grows to 5 to 7 true leaves and the scion grows to 4 to 6 leaves, it can be grafted. One afternoon before grafting, every 15 kilograms of water was mixed with penicillin and 800,000 units of streptomycin. After mixing, eggplant seedlings were sprayed to eliminate germs. Grafting is carried out using a splicing method, that is, the rootstock is cut transversely from the root at 2 to 3 leaves, and a 1 cm deep hole is cut longitudinally from the middle of the transverse plane. The scion is cut horizontally from the top 2 to 3 leaves, and then at the top. A wedge is formed on both sides of the cut surface, and then the scion is inserted into the rootstock so that the cut surface of the cut surface fits well and can be clamped with a grafting forceps. 5. Management after grafting. Grafted seedlings were covered with arch sheds for the first 3 days, kept at 28-30°C during the day, 18-20°C at night, and about 25°C soil temperature. In order to avoid direct sunlight, it is shaded from 10am to 4pm. Gradually reduce the temperature after 3 days, sooner or later to gradually increase the light time, the temperature can be used when the shading and gas phase combination method to adjust, during the day at 25 ~ 27 °C, 17 ~ 20 °C at night. After 6 days, the film of the small arch can be pulled apart and gradually enlarged. After 8 days, the small shed was removed and transferred to normal management. In the first 3 days of the graft healing period, the relative humidity of the air should reach about 90%. After 3 days, the relative humidity of the air should be kept between 70% and 80%. After 6 days, the relative humidity of the air should reach 60% to 65%. Third, planting can be planted after about 30 days after grafting. Before every 1/15 hectares of planting, 5,000 kg of organic manure, 25 kg of diammonium phosphate, and 15 kg of potassium sulfate were planted. Before the colonization, the medicinal smoked shed was used. Then open the ditch to the north and south, 60 cm from the small row, 80 cm from the big row, 5 to 6 cm deep from the planting ditch, and pouring water from the bottom of the ditch. Colonization shall be carried out on sunny days without wind conditions. Planting the seedlings at a spacing of 40 cm shall be followed by watering the cover soil. After the water seeps, the soil will be ridged on the 3rd day, and the ground will be over 2 cm from the surface, forming a ridicule with a height of 10 cm, after 7 days. The seedlings were poured with water, and the plastic film was covered 15 days later. There are 2500 colonies per 1/15 hectares. When planting soil cover can not exceed the interface, or eggplant grows adventitious roots, lost the role of grafting disease prevention. Fourth, management after planting after planting management and eggplant conventional cultivation methods are basically the same, the main difference is that the cultivation of grafted eggplant should not be seedlings, should be promoted in the end. After the planting, the sun will be shaded at noon for the first 3 days to prevent wilting. After 4 to 5 days of planting, water should be poured once to make it slow. In the process of growth and development, the temperature during the day can be maintained by means of shading, covering the membrane and releasing air. 25 ~ 30 °C, after entering the fruiting period, it is necessary to increase the temperature difference between day and night, to maintain proper temperature during the day, the night temperature dropped to 15 ~ 18 °C. The water and fertilizer management, depending on soil moisture watering, the early stage of small water, to the door when the eyes open, you can apply the first fertilizer, top dressing using ternary compound fertilizer, can not be partial nitrogen fertilizer, usually 15 to 20 days topdressing 1 times , 6 to 7 days of watering, cultivating once. The pruning method can use the commonly used double stalk pruning method. In winter, the lighting time should be extended as much as possible to enhance the light intensity. In this way, the market can generally be harvested 90 to 100 days after planting.

Amino Acids

Amino acids are the basic units of proteins and are essential organic compounds in life. There are about 500 different amino acids in nature, but among the amino acids that make up the proteins of living organisms, 20 are standard amino acids, which are connected in different sequences to form proteinaceous proteins that perform various physiological functions in living organisms.

Amino acids can be divided into the following categories according to their location and function in proteins

1.Essential amino acids

9 amino acids that the body cannot synthesize by itself or the synthesis speed cannot meet the needs, and must be ingest through food, including lysine, tryptophan, phenylalanine, methionine, threonine, isoleucine, leucine, valine and histidine (infants also need histidine).

2.Non-essential amino acids

The human body can synthesize by itself and does not need to obtain directly from food, including glutamic acid, aspartate, alanine, serine, glycine, proline, cysteine, etc.

3.Conditional essential amino acids

Under specific conditions (such as disease, stress), the human body's synthetic ability is reduced, and additional supplements are needed, such as arginine, glutamine, etc.

Amino acids are also widely used in the field of skin care, as skin care ingredients, they mainly have the following effects

1.Moisturizing

Some amino acids such as glycine, alanine, etc. have good hygroscopic properties, which can help the skin retain moisture and enhance its moisturizing ability.

2.Repair

Such as arginine, glutamic acid, etc. participate in the repair and regeneration process of skin cells, promoting wound healing.

3.Anti-aging

Certain amino acids have antioxidant effects that can help fight free radical damage and slow down skin aging.

4.Cleansing

Amino acid surfactants, such as sodium lauryl sarcosine, are commonly used in cleansing products for sensitive skin due to their mild, non-irritating properties.

Therefore, amino acids are not only essential for human health, but also play an important role in beauty and skin care products.
