Ledu Changjiao is based on the horn of the Niujiao area in the county. The pig's large intestine pepper is the female parent. It was selected by sexual crossbreeding. It was approved by the Qinghai Provincial Crop Variety Approval Committee at the end of 1996 and named as Ledu Changchi. The cultivated area of ​​this variety is more than 200 hm2. The products are not only supplied to the province, but also sold to surrounding provinces and regions, which are very popular among consumers.
First, the characteristics of the characteristics
Ledu long peppers have medium growth, plant height 95-110cm, development degree 80-90cm, leaves dark green, stem diameter 2.8 ~ 2.9cm. The 12th leaf leaves the first inflorescence, the fruit is long-conical, the surface is shrunk, angular, the fruit is dark green, the red fruit is dark red, and the flesh is 3mm thick. Spicy, aromatic, delicate flesh, vitamin C content 220.5mg/100g, soluble sugar 4.35%, fruit storability. Raw food, cooked food, sauce, and marinated.
Protected fields and matured. Winter energy-saving solar greenhouses, early springs and autumn-expansion ordinary greenhouses, summer and autumn greenhouses can be cultivated, basically can be planted on an annual basis. The whole growth period is 245-250 days, during which the accumulated temperature of ≥0°C is above 4900°C, and the accumulated temperature of ≥10°C is above 4174°C. It has strong cold resistance, moderate heat resistance, 75% fruit set rate, and the incidence of pepper blight is below 3%. It is resistant to pests and diseases and has strong adaptability. The yield of 667m2 is 2500~4000kg.
Second, cultivation techniques
1. Sowing at the right time, the listed Ledu Changjiao can be planted in batches from the middle and late July to the middle and late January of the first year of the agricultural area in the eastern part of the province.
2 . Cultivate strong seedlings (1) Planting 667m2 field with 150~200g seed; (2) Planting nutrient soil into the seedbed; (3) Soil moisture of 80%～85% when planting, covering 1~2cm nutrient soil after sowing (4) After emergence and time, seedlings, seedlings, and diseased weak seedlings; (5) standard seedling age 80-90 days, seedling height 20cm, true leaves 9-10 pieces, stem diameter 0.4-0.6cm, plants Robust, no pests and diseases.
3. Applying the base fertilizer, high ridges and planting the long peppers require high water and fertilizer conditions. 667m2 requires organic fertilizer 8000kg, diammonium phosphate 40kg, superphosphate 20-30kg, plant spacing 35cm70cm, 667m2 planting 3500 plants.
4. Strengthen field management in winter and spring, do a good job of heat preservation and warming measures, strengthen water and fertilizer management during harvesting period, topdressing 3 to 4 times, and apply 15kg of urea or 20kg of diammonium phosphate with water 667m2 each time. Maintain daily temperature of 25 ~ 28 ° C, night temperature of 12 ~ 15 ° C, air relative humidity of 60% ~ 70%, soil relative humidity of 70% ~ 80%.
5. Timely prevention and control of pests and diseases and rotation of non-solanthine vegetables, before the sowing, using warm soup soaking or soaking seeds to treat seeds. In the field, the disease and root rot are treated with anti-virus cockroaches, nail cream copper, metalaxyl and other agents to irrigate and spray, and prevent and control 2 to 3 times.
6. Timely harvesting is generally 20 to 25 days after flowering, from flowering to green ripe fruit harvesting period of 20 to 25 days, green ripe fruit harvesting period to red ripe fruit harvesting period of 42 to 45 days. Slow growth in winter, harvest time can be extended by 10 to 15 days.

Plasticizer is widely used in industrial production of polymer materials, also known as plasticizer. Any substance added to a polymer material that increases the plasticity of the polymer is called a plasticizer. Plasticizer can improve the performance of polymer materials, reduce production costs and increase production benefits. [1] is a kind of important additives, chemical products as additives commonly used in plastics, concrete, mortar, the material such as cement, gypsum, cosmetic and detergent, especially in PVC plastic products, in order to increase the plasticity of the plastic and improve the strength of the plastic, you need to add phthalic acid ester, sometimes its content can be up to 50% of the products. Weakened the effect of plasticizer mainly resin molecular valence bond between time, increase the mobility of the resin molecular bonds, reducing resin molecular crystalline, increase the plasticity resin molecules, enhanced the flexibility, easy to machining, can legally used for industrial purposes, widely exists in food packaging, cosmetics, medical equipment, water and environment. Such as plastic wrap, food packaging, toys and so on.
