- Q: What is the inorganic salt
- Inorganic salts are inorganic compounds in the salt, formerly known as minerals, the body has been found in more than 20 species, including constant elements of calcium, phosphorus, potassium, sulfur, sodium, chlorine, magnesium, trace elements are iron, zinc, , Chrome, cobalt, iodine, etc. If you pay attention to diet diversification, eat less animal fat, eat brown rice, corn and other coarse grains, do not eat too much refined flour, the body can make the inorganic salt to maintain normal level.
- Q: Which crop feet can provide C N inorganic salts for fungal growth
- Plant growth requires a variety of inorganic salts, which require the most is nitrogen, phosphorus, potassium containing inorganic salts. If a lack of some inorganic salts, plants can not grow normally. Kind of crops need fertilization, farm manure contains organic matter, the microbial decomposition of the soil will produce a large number of inorganic salts for plant growth and utilization, the role of fertilizer is to provide a variety of plant growth of inorganic salts. Therefore, in agricultural production, the application of fertilizer and farm manure is intended to provide a variety of inorganic salts for crops.
- Q: How can experiments prove that there are inorganic salts in the leaves of plants
- The experimental leaves used to dry, crushed into powder or sintered ash, and then the analysis of mineral elements, we can learn.
- Q: The lack of three major inorganic salts can cause symptoms in the plant
- Nitrogen: to promote cell division and growth, so that leaves grow lush. Lack of performance: plant thin and thin, leaves yellow, severe leaves were light brown.
- Q: What is the disease of inorganic salt crystals?
- Drink less, the urine will be reduced, the urine of the inorganic salt concentration will be high, the discharge of urine encountered outside the cold air, will immediately cool, urine inorganic salts to precipitate down, so that urine Into the lime watery white turbid liquid. Check this urine, the urine heated to a certain temperature will make it clear; also due to temporary urine alkalization caused by white turbid urine, such as taking alkaline drugs or After a lot of alkaline food, or eat can make the inorganic salt in the urine of the increase in the content of food, fruit, vegetables, there will be white urine.
- Q: Inorganic salts are not nutritious
- Nutritional substances are sugar protein fat three nutrients
- Q: Why vegetables and fruits contain rich inorganic salts
- Because they are plants! From the biological point of view, they are the nature of the organic matter into inorganic salt carrier
- Q: Is the inorganic salt the same as the saline?
- Inorganic salts are inorganic compounds in the tears, originally called minerals. A large number of elements are calcium Ca, phosphorus P, potassium Ka, sulfur S, sodium Na, chlorine Cl, magnesium Mg, trace elements iron, zinc, selenium, molybdenum, fluorine , Chromium, cobalt, iodine and the like.
- Q: as a example potesium,sodium,magnees,calcium
- I'd okorder /
- Q: The power of the water and inorganic salts in the plant is derived from the action of the plant
- The main process is: soil moisture → root hair → root catheter → stem catheter → leaf catheter → stomata → atmosphere.
