How to Safely Apply Vegetables with Chloride Fertilizer
For the sake of safety, it is not advisable to use ammonium chloride and double chlorine compound fertilizer with ammonium chloride and potassium chloride as raw materials in greenhouses.
1. Spinach Spinach is a crop with strong chlorine resistance. Potassium chloride or chlorine-containing compound fertilizers can be used. As long as they are not used in excess, they can achieve the same effect as potassium sulfate. Per acre spread organic fertilizer 3000 ~ 4000 kg, nitrogen, phosphorus and potassium content of 15% of the chlorine compound fertilizer 2 ~ 3 times, then topdressing potassium chloride 5 kg per mu, with a small amount of water The application effect is good.
Second, radish and radish is also a strong chlorine-tolerant crop, you can use potassium chloride or potassium chloride compound fertilizer, base fertilizer spread per acre of 3000 to 4000 kg of organic fertilizer, superphosphate 30 to 40 kg, Potassium chloride 5~7.5 kg or plant ash 100 kg. Deep plowing 25 to 30 centimeters, squatting do flat, can be recovered during the growth of 2 to 3 times fat. For the first time, a little bit of nitrogen fertilizer can be applied according to fertility; the second time in the rosette stage is mainly nitrogen fertilizer, with the recovery of potassium chloride from 3 to 4 kilograms per mu; the third time during the growth of the fleshy root, topdressing with potash fertilizer is the main method. The amount of potassium chloride per mu is 4 to 5 kg. Water several times after fertilization to keep the soil moist and promote growth.
Third, although the cucumber cucumber is a strong chlorine-tolerant crop, but the critical value of chlorine is lower than spinach and radish, can be appropriate amount of potassium chloride or single potassium chloride compound fertilizer, but to control the amount and pay attention to the application method .
4. tomato Tomatoes are crops with chlorine tolerant upper-middle crops. The critical value of chlorine resistance is lower than that of cucumbers. In the case that it is difficult to purchase potassium sulfate and potassium sulfate compound fertilizers, potassium chloride or potassium chloride alone can also be used. For compound fertilizers, it is necessary to strictly control the dosage and pay attention to the application method.
5. Eggplant and Cabbage Eggplant and Cabbage are also the upper-half-resistant crops with chlorine tolerance, but the critical value of chlorine tolerance is lower than that of tomatoes. Potassium chloride should be applied as little as possible or in combination with potassium sulfate.
VI. Crops with low chlorine tolerance
The crops with low chlorine tolerance are celery, pepper, Chinese cabbage, rapeseed, strawberry, and cauliflower. It is not appropriate to use chlorinated fertilizer.
Seven, crops with weak chlorine resistance, such as potatoes and sweet potatoes, are weak crops with low chlorine tolerance, and even less suitable for the application of chlorinated fertilizers.
It is very important for the synthesis of polyurethane adhesives and sealants, which directly affects the mechanical properties and process In a broad sense, most of the weak reductants are antioxidants and are selected for different industrial USES. Weak reductants with high chemical and physical stability, or with low toxicity, can be skillfully used as antioxidants in formulations. For example, citric acid is a weakly reducing organic acid that can be used in beverage formulations to act as an antioxidant. Food is easy to oxidize and deteriorate for a long time, so a small amount of antioxidant can be added to prolong its storage time. High polymer materials such as plastic, synthetic fiber and rubber are prone to thermo-oxygen degradation. Adding antioxidant can maintain the excellent performance of high polymer materials and prolong their service life.
