Spring cucumber planting time
Spring cucumber refers to the cucumber that is raised in winter and harvested in spring. Let's take a look at the sowing time and planting time of spring cucumber:
1. Sowing time of spring cucumber: The sowing date of spring cucumber is determined according to the planting period. The suitable calendar age for planting is 40-50 days, and the physiological seedling age is four leaves and one heart. If the calculation is based on the calendar age, the seeding will be carried out 40 to 50 days before the planting. The length of physiological seedling age is related to the method of seedling raising. It takes 50 to 55 days to grow seedlings in Yangshuo or solar greenhouses; 45 to 50 days in warming greenhouses; and 45 days in greenhouses using electric heating lines. Therefore, the seedling methods are different and the sowing time is different. Practice has proved that rapid seedling not only saves time, but also emerges quickly and vigorously, with high output in the early stage. Where possible, try to use rapid seedlings.
2, the colonization time of spring cucumber: the colonization time of spring yellow claws is after the local night frost, the average temperature is more than 18t. The Beijing, Tianjin, and Shijiazhuang areas are generally planted after the end of April. In order to slow down the seedlings, you should choose a sunny day to plant seedlings, not to plant in cloudy and windy days. The density of colonization is mainly determined by the characteristics of the variety.
Autumn cucumber planting time
Autumn cucumber cultivation is only in the frosty area refers to the cultivation before the beginning of the first frost, while in the perennial frost-free area, it is the cucumber listed in the autumn of summer cucumber. The growth period of autumn cucumber is only 80-90 days, which can be directly cultivated. It can also be transplanted, planted in open fields or greenhouses.
Autumn cucumbers are generally sown about 70 days before the frost, and seedling transplanting can be carried out 7 to 10 days in advance. Because the seedling stage and the pre-growth period are in the hot and rainy season, the autumn cucumber has serious pests and diseases and the yield is low.
PC plastic,full name Polycarbonate.
PC plastic is a kind of excellent comprehensive performance engineering plastics.It has excellent physical, mechanical, electrical, and thermal properties,so it's known as the "king of the transparent plastic'
Anti - static PC SHEET, conductive PC SHEET,fireproof PC SHEET,PC fiber - resistant, PC GF SHEET, PC+ABS SHEET,anti-ultraviolet ray resistance PC, food grade PC, anti - chemical PC.
3,Excellent physical, mechanical, electrical and thermal properties
Polycarbonate is not resistant to ultraviolet light, no resistance to alkali, resistance to hydrolysis stability is not high, is the main performance defect is sensitive to the gap, resistance to organic chemistry, scratch resistance is poorer, long-term exposure to ultraviolet light yellow, are vulnerable to the erosion of some organic solvents.
1. Dust-free room spacer
2. Equipment shield and test fixtures;
3. Commercial Building Lighting;
4. Soundproof walls;
6. Components for medical and pharmaceutical devices;
7. Face shields;
8. Skylights, etc
The purpose of the modified PC Plastic is to toughen, improve the processing performance, reduce the residual deformation, and increase the flame retardancy, etc.
PC/ABS can improve bending modulus, heat resistance and plating performance.
PC/PET and PBT can improve drug resistance and solvent resistance.
PC/PMMA added plexiglass to enhance the appearance of pearlescent color.
PC/PA and HIPS can improve impact toughness and surface finish.
PC/HDPE can improve water resistance, aging resistance, weather resistance and LDPE.
The PC Plastic USES fiberglass or carbon fiber to enhance modification and improve mechanical strength.
The flame retardant grade PC Plastic can be made with bromine flame retardant and antimony trioxide.
Other and polysulfone, aromatic polycarbonate, polyvinyl formaldehyde, polypropylene, polystyrene can be modified to achieve the balance between economy and performance.
Combustion condition: easy, softening foaming
Flame status: small amount of black smoke
After the fire: out of the fire
Bouquet: no special taste
Specification: the thickness of PC Plastic sheet material can be produced from 0.3mm to 1.9mm, the normal width is 600mm, the width cannot exceed 1200mm, the length is not limited.
The thickness of plate can be produced from 2mm to 180mm, the usual specification of 2-10mm is 1000mm* 2000mm, and the commonly used specification of 10-180mm is 600*1200 mm. PC Plastic sheet can also be customized according to requirements, and the width cannot exceed 1200mm, and the length is not limited.and The diameter of the PC Plastic rod can be produced from 2mm to 250mm, the length is 1 meter, and it can be ordered to be more than 3 meters in length.
Color: Black and clear, can also be made another color, and the color order is 500KG.
Modified varieties:PC Plastic can be added to the Glass Fiber, copper powder, and molybdenum disulfide enhancement plate according to customer's requirements.
Add antistatic agent to the permanent plate, the volume resistance value of 10 to the 6 to 9 power.
Add flame retardant to the flame retardant board from UL 94v-0 to HB combustion grade, and other modification requirements are required to customize various additional properties according to the actual use of the customer.
Product certification: most environmental certification reports and safety reports for raw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
