Potassium sulfate is a common potash fertilizer. It can improve crops ability of drought resistance, cold resistance, lodging resistance,and pest disease resistance. It can also promote flowering and fruiting, and better use of nitrogen to increase protein content, and promote the production of sugar and starch. Especially suitable for tobacco, sugarcane, potato, sweet potato, grape, tea tree and other high potassium crops and sulfur-like cruciferous crops (such as rapeseed, beans, etc.) .Increase the strength, fineness,color purity of cotton and hemp crop fiber.

Potassium sulfate must be combined with nitrogen and phosphorus fertilizers for fully effect.
1. Do not apply to the roots of crops, neither to stems and leaves.
2. Not recommended for use in paddy fields or soil with strong reduction
3. Must be applied with lime or calcium magnesium and phosphate fertilizers for long-term application on the acidic soil.
4. Better to apply in small amount or mixed with farmyard fertilizer for sandy soil.
5. Prevent rain and damage during storage and transportation.

Just as the price of phosphors has increased 10 times and the cost of energy-saving lamps has increased sharply, its competitor LED lights have continued to fall due to the price cut of upstream chips. The author learned from a number of lighting companies that LED chips have fallen from 6 yuan to 2 yuan in the past year, driving LED lights down by 30%, the average price is 30-100 yuan, the most flat is only 10 yuan, but the quality is mixed.
The price of LED chips diving LED lamps is approaching energy-saving lamps Two years ago, the price of LED chips of 1 watt was about 3 US dollars, but now it has dropped to less than 1 US dollar. Some Taiwanese and mainland-made chips are cheaper, even 3 yuan. Wu Yulin, president of Foshan Lighting Association, told the author. Xu Rui Optoelectronics, which started production of LED chips in May, told the author that the price of chips has dropped from more than 6 yuan to more than 2 yuan in the past year.
It is understood that the chip accounts for at least 1/3 of the cost of LED lamps, and the price reduction of the chip directly drives the price of LEDs to drop. Since the price of chips has dropped at a rate of about 20 per year in recent years, the price of LED lamps has generally dropped from 7-10 times that of energy-saving lamps two years ago to 3-4 times in the near future. At present, the price of energy-saving lamps has been stable at 6-10 yuan, and the price of general LED lamps has dropped from 50-300 yuan to 30-100 yuan. Wu Yulin said that the 9-watt LED lamp that he was sent to Germany three years ago was sold for $30. As the price of the chip continued to drop, it had dropped to $10.
LED lights to increase sales prices approaching energy-saving lamps LED lights price increase sales rose more than 10%. Yesterday, I visited the Wal-Mart and Weiguo Road lighting stores in Chancheng. I learned that the sales of LED lights generally increased by 10-30 in the first half of the year. In the past year, the price of LED products has generally decreased by 30, and the price of mid-range LED lamps is between 100 and 300 yuan. Our business in the past two months has maintained a growth of 10. Ou Jingyang, a business representative of Qiangguang Environmental Lighting Co., Ltd., which is operating on Weiguo Road, said.
At the same time as the price cut of the chip, the market has also begun to appear low-cost and inferior LED lights. Luo Jianguo, general manager of LED manufacturer Foshan Songbei Optoelectronics Technology Co., Ltd. told the author that the 10 yuan LED lamp with the same price as the energy-saving lamp has appeared on the market. But the quality is very poor, the price of LED lights will definitely go down, I guess will gradually enter the ordinary family in batches next year.
Ou Jingyang of glare lighting said that some manufacturers blindly pursue low-cost competition, and even use one yuan of inferior LED chips, which will be broken in less than a week after being sold, which will have a negative impact on the current LED market.
Analysis: The price of LED lights for export enterprises with downstream manufacturers has dropped, which has brought benefits to downstream manufacturers to open up the market. Wu Yulin, president of the Municipal Light Association, said that the continuous improvement of LED cost performance has brought opportunities for the company to expand its market. In the first half of last year, the company's export of LED lamps is 100% growth, and many export companies in Foshan are also such high-speed growth.
However, chip price cuts have also increased the pressure on upstream chip manufacturers. A person in charge of Xu Rui Optoelectronics told the author that the price cut of the chip is very large for our profit margin.
