First, according to the different chlorine tolerance of crops. According to the tolerance of crops to chlorine, the crops are divided into three categories: one is strong chlorine-tolerant crops, such as rice, cotton, barley, sorghum, etc.; spinach, pumpkin, kidney beans in vegetables; kiwi, hawthorn, peach tree in fruit trees, Bananas; second, chlorine-tolerant crops such as corn, wheat, peanuts, soybeans, and rapeseed; and third, crops that are poorly resistant to chlorine, such as sweet potatoes, potatoes, watermelons, tobacco, tea trees, and lettuce in vegetables. Chlorine-containing fertilizers should be applied first to strong chlorine-tolerant crops, and secondly to chlorine-tolerant crops. Crops with poor chlorine tolerance should not be applied to avoid "chlorine damage", reduce yield and affect quality.
Second, choose the soil that is suitable for application. The chlorinated fertilizer should be applied to a neutral or calcareous soil with a pH > 6.5 and rich calcium. If applied in acidic soil, it is advisable to first apply lime or other alkaline fertilizer. After application, the soil is mixed and covered with deep application of chlorinated fertilizer. In rainy areas or rainy seasons, the application of chloride-containing fertilizers, chloride ions can be lost with water, not easily absorbed by the soil to cause crop chlorine damage, in areas with large rainfall and rice production areas, suitable for the application of chloride-containing fertilizer. In saline-alkali soils, chlorinated fertilizers should be banned due to high chloride ion content.
Third, as a compound fertilizer application. Rational application of nitrogen, phosphorus and potassium fertilizers can not only exert the interaction between nutrients, but also improve some undesirable properties of single fertilizer before mixing. Practice has shown that the application of potassium chloride, ammonium chloride and urea, ammonium phosphate and calcium to form a binary or ternary compound fertilizer can alleviate the harm of chloride ion and the undesirable characteristics of moisture absorption and agglomeration, and the combination of nitrogen, phosphorus and potassium Application can play a role in complementing each other.
Fourth, master the application method and dosage. Containing chlorinated fertilizer can be used as base fertilizer or top dressing, but according to the water solubility of chloride ion, it should not be used as seed fertilizer or top layer fertilizer. When chloride ions are in contact with water, water-soluble chlorinated fertilizer is formed, which increases the concentration of aqueous solution, which is unfavorable for crop seed germination and seedling growth, so it is not suitable for direct contact with crop seeds and seedlings. The base fertilizer should be applied 4-6 cm below the soil surface, or applied to the crop line to avoid contact with seeds and seedling roots. The application of dryland crops can be carried out by means of application and timely tillage after application. The suitable application rate of chlorinated fertilizer is preferably less than 200 mg/kg of chlorine concentration, 30-40 kg of potassium chloride, 20-40 kg of ammonium chloride and 40-50 kg of potassium chloride compound fertilizer.
5. Cooperate with organic fertilizer and phosphate fertilizer. At the same time of applying the chlorinated fertilizer, the application of the organic fertilizer can not only improve the fertilizer effect of the chlorinated fertilizer, but also reduce the adverse effects of chlorine. According to the antagonism of chlorine and phosphorus ions, the appropriate application of phosphate fertilizer can utilize the antagonism of chlorine and phosphorus ions to reduce the toxicity of chlorine, thereby achieving the purpose of safe application. In soils with strong acidity (pH below 5), the application of magnesium phosphate fertilizer (lime or grass ash) can be applied once every 1-2 years, and the fertilizer effect of chlorinated fertilizer can be exerted. However, it should be noted that the above fertilizers should not be mixed directly.
Hitachi Launches New TX Series Escalator for
India, Asia and the Middle East
Tokyo, August 21, 2017 --- Hitachi, Ltd. (TSE: 6501, [Hitachi") and Hitachi Building Systems Co., Ltd. today announced the launch of the new TX Series escalator for India, Asia and the Middle East. The escalator has already been released in China*1, and will be released in stages across the remainder regions, commencing August 21, 2017.
In July 2016, Hitachi integrated its escalator businesses of Japan and China, consolidating its resources and enhancing its business operations in both countries, centered around its key business location in Guangzhou, China. The new TX Series escalator launched by Hitachi is a model that meets multiple standards in China, India, Asia and the Middle East. The model follows the same concept for the machine room-less elevator for Asia and the Middle East which was launched in September 2016. In addition to conforming to Chinese safety and quality standards for escalator equipment, the TX Series will be manufactured in accordance with Hitachi's own strict standards of safety and quality, adhering to safety standards in all other regions. It also adopts a functional design based on the concept of an escalator that fits closely with the unconscious actions of users, in the pursuit of their ease and comfort.
The TX Series offers flexibility with a selection of various product specifications, as well as its excellent design and safety features, designed to cater to a diverse range of customer needs. It also saves space required for the installation, covering a smaller area in comparison with existing products*2.
Hitachi will begin sales of the TX Series in Thailand, followed by launches in the Philippines, Malaysia and various other regions, and aims to receive orders of 10,000 units in 2018 in China, India, Asia and the Middle East.
Features of the TX Series
-
Safety
The TX Series offers various new safety features designed with optimal user safety in mind. The side portions of the steps are 8 mm higher than the central portion to prevent accidents in which a users' shoe can become caught between the step and the skirt (side wall) of the escalator. The new TX series has also been fitted with brushes located at foot level on the left and right skirts to let users know if their foot comes into contact with the side walls. A special finish has also been adopted for the landing plates at the entry and exit points of the escalator to prevent users from slipping when getting on and off the escalator. -
Design
The TX Series adopts a simple and functional design that offers the smoothness, safety and comfort that users unconsciously expect to experience when riding an escalator. For example, by minimizing the size of the metal frame supporting the escalator's balustrades, the TX Series' design maximizes the size of the glass surfaces, and achieves greater simplicity at the entrance and exit points (landings) by reducing the number of recesses and protrusions around the hand rail. Additionally, by expanding the installation space of the light fixture, the TX Series also enables enhanced lighting options for illuminating the entire surroundings of the balustrades. -
Space saving
By shortening the span dimensions*3 by 150 mm, the TX Series has made it possible to install escalators in more confined spaces where installation presents difficulties with conventional product designs.
