The fertilizer requirement characteristics of rice in north China with the "test soil formula and package fertilizer" plan: The northern rice is dominated by indica rice, with higher yield and better quality. According to research, for every 500 kilograms of rice produced, about 10 kilograms of nitrogen, 5 kilograms of phosphorus, and 15 kilograms of potassium need to be absorbed. Rice top-dressing misunderstanding: 1. Disregard potassium fertilizer. Some farmers' friends often use only nitrogen (ammonium carbonate, urea) or nitrogen-phosphorus fertilizer (diammonium) in rice dressing. Rice is one of the most hipotassic potassium crops in food crops in the field, and indica rice needs more potassium than indica rice. In the absence of potassium, first the rice grows irregularly and the plants become dwarf, followed by accelerated aging and death of the leaves, and brown rust on the petioles. In addition, the poor growth of rice roots and the small amount of roots in the state of potassium deficiency are fine and short, affecting rice's absorption and utilization of water and nutrients, and seriously restricting rice yield. High-potassium rice plants have developed root systems, strong stems, good mechanical development within the stem, strong resistance to breaking, and full kernels, which also have a role in improving disease resistance. 2. Ignore trace elements. In recent years, the deficient symptoms of trace elements have become more and more common in rice. For example, if the rice is deficient in zinc, the plants are likely to be dwarfed and the weak seedlings will not grow. Sulfur deficiency in rice leaves young yellow leaves and fewer tillers. Therefore, in the production of rice, we should pay attention to the application of trace element fertilizer lion and horse fruit glycosides, "small fertilizers" can often produce "big effect." 3. Excessive use of sulphur-containing fertilizers in base and topdressing. Potassium sulphate-type fertilizers should not be used in paddy fields because potassium sulfate contains sulphate. In the flooded state, sulphate roots are reduced to harmful hydrogen sulphide, causing black rice roots and affecting nutrient uptake. Therefore, the use of potassium chloride in paddy fields is more economical and more efficient. 4. The fertilizer is not the right choice. In paddy fields, excessive use of available fertilizers can result in serious loss of fertilizer and low nitrogen fertilizer utilization. The use of long-term fertilizers in paddy fields can effectively reduce the leaching loss of fertilizers and greatly increase the utilization rate of nitrogen fertilizers. Zhongde brand compound fertilizer is a good quality fertilizer. Public German Fertilizer (Yantai) Co., Ltd. is a German-owned company. The company produces the Zhongde brand series of fertilizers. It uses German agricultural experts to specially design fertilizer formulas for Chinese rural areas. There are two series of available fertilizers and long-term fertilizers. The outstanding characteristics of Zhongde long-acting fertilizer are: high content, complete nutrients, moderate nutrient release rate, long fertilizer effect, sufficient stamina, and high fertilizer utilization rate (of which nitrogen fertilizer efficiency is 20 days longer than normal small granular urea, and the utilization rate is high. More than 20%). The use of this long-acting fertilizer in paddy fields can effectively reduce the leaching loss of fertilizers. Long-term fertilizers have long-lasting fertilizers and high utilization rates have the most prominent advantages. Suitable for rice base fertilizer formulations are: 19-19-19,18-18-18,22-16-18 suitable for rice topdressing formula: 30-8-12,30-5-14. This high-nitrogen and high-potassium formula meets the needs of rice, allowing rice to eat the things it wants to eat (nitrogen and potassium) without wasting anything that cannot be eaten (phosphorus). Rice fertilization points: First, the application of basal fertilizer high-yield rice basal fertilizer application principle is organic manure (farm fertilizer) in conjunction with chemical fertilizer application, the use of full-fertilization methods. As for the application amount of organic fertilizers and chemical fertilizers, it should be determined according to the requirements of the soil testing formula. General farmyard fertilizer 1000 kg or organic fertilizer 50 kg, chemical fertilizers available 19-19-19,18-18-18,22-16-18 30-50 kg of German-made fertilizers, timely dressing 1, early application sub-fertilizer. Normally, the top dressing is applied about 5 to 7 days after returning green, which promotes the early growth of rice tillers and early projection of high yield, which is particularly important in the cold regions of northeast China. The best Mushi 30-8-12 or 30-5-14 potassium chloride Zhongde compound fertilizer for this period is 5-10 kg. At the same time, the foliar spray of lion and horse brand high efficiency foliar fertilizer “Ye Cui” 600 times liquid, to promote rapid growth of stems and leaves. 2. Steady application of panicle fertilizer. Potash fertilizer has the greatest impact on the formation of young panicles. Therefore, the timely application of panicle fertilizer in the early stage of young panicle differentiation (usually before and after the jointing stage) is critical for high yield. This period is best Mushi 19-19-19, 18-18-18, 22-16-18 potassium chloride Zhongde brand compound fertilizer 10-15 kg. At the same time, the foliar spray of lion and horse brand high-efficiency foliar fertilizer “Huabao (900 times) plus “Fructus lycii” (5,000 times) for a total of 1-2 times to promote grain plumpness, increase grain weight and reduce empty grain size.3 See seedlings chasing grain fertilizers.The main role of grain fertilizers is to maintain appropriate nitrogen levels and high photosynthetic efficiency of the leaves to prevent the premature decline of roots and leaves, so that the grain is full and full.If the plants do not see obvious lack of fertilizer, do not blindly apply the fertilizer. , Otherwise it will cause high nitrogen concentration, increase the consumption of carbohydrates, and produce negative effects.If the seedlings have signs of premature decline, 17-17-17 potassium chloride type Zhongde brand compound fertilizer may be applied for about 5 kilograms per acre. What needs to be promoted is that after the head of rice is replenished, 1-2 times of lion and horse brand efficient foliar fertilizers “King Wang” (900 times) and “Pianguaxin” (5,000 times) should be sprayed on the leaves to make the grain fuller and fuller. It can significantly improve the quality of rice.Suggestions: 1) In the paddy fields, increasing silicon fertilizer can significantly increase rice yield.2) Use potassium sulfate and ammonium sulfate fertilizers with caution.If you need to supplement sulphur fertilizer, you can spray on the surface. - 3 times of Potassium Sulfate, 200 grams per acre, dilute 500-fold, while the supplement potash, increased grain weight, complementing sulfur fertilizer.

Moisturizing Raw Materials

What are the best moisturising ingredients ingredients

Moisturizing ingredients in cosmetics can be divided into the following categories:

1. natural moisturizing factors: this type of moisturizing raw materials mainly include amino acids, urea, lactic acid, sodium PCA, etc. They can simulate the skin's natural moisturizing mechanism to provide long-lasting moisturizing effect.
2. Polyols: including glycerin, propylene glycol, butylene glycol, etc. These ingredients have good hygroscopicity, which can adsorb water in the air and provide moisture to the skin.
3. polysaccharides: such as hyaluronic acid, alginate, etc., this kind of ingredients can form a protective film on the skin surface, preventing water evaporation, to provide long-lasting moisturizing effect.
4. Fatty acids: such as fish oil, olive oil, etc., these ingredients can provide moisturization for the skin and improve the dryness of the skin.
5. proteins and peptides: such as serine, collagen, etc., these ingredients can enhance the skin's ability to moisturize, improve skin elasticity.
6. plant extracts: such as aloe vera, rose, witch hazel, etc., this kind of ingredient is rich in active ingredients, can provide the skin with sufficient moisture and nutrition.
