Q:Which minerals is richest source of Inorganic Salts ?
Minerals are inorganic salts - eg.potassium nitrate - absorbed by plants from soil - a good source of inorganic nitrogen and potassium.
Q:Does the plant roots absorb inorganic salt ions must be active
Plants absorb inorganic salts and do not necessarily absorb water. Plants absorb moisture and absorb inorganic salts are two relatively independent processes. Plants absorb moisture through the infiltration of root cells to absorb water, the process is essentially free of water diffusion process, neither the carrier nor the need for energy; and plant absorption of inorganic salts is carried out by means of active transport, This process requires the carrier and consumes the energy generated by cell metabolism. Of course, plant water absorption and absorption of inorganic salts are a certain association, inorganic salts to be dissolved in water to be absorbed, and inorganic salt ions in the transport of plants can not be separated from water.
Q:The inorganic salt is composed of?
Inorganic salts are the general term for various inorganic salts. They are composed of inorganic acid radicals and metal cations or ammonium salts, mainly salts of organic acid salts, such as sodium chloride, potassium chloride and so on.
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:Common inorganic salt ions will appear when the corresponding symptoms
Iron ion: iron deficiency anemia
Q:What are the effects of water, inorganic salts, carbohydrates, proteins, fats and vitamins?
The main physiological function of protein: 1. constitute the body, repair organization. (The body's muscles, blood, skin, hair, etc. are not the same as the protein is not formed.) 2. Regulate the physiological function. (The body of enzymes, hormones, antibodies, etc., are also directly or indirectly from the protein.) 3. Supply of energy. (Per gram of protein in the body of oxidation can release 4 kcal of heat for metabolic purposes.)
Q:Please tell in your own language how water and inorganic salts are transported from the soil to the leaves.
The roots of plants are usually divided into roots, roots, roots, roots (roots, roots and roots) for the absorption of roots, the absorption of roots from the soil to absorb water and inorganic salts, through the transport organization to reach the xylem catheter, through the catheter To the various organs of the plant (including leaves). The effect of the absorption of roots through the semipermeable membrane of the role of penetration, that is, the concentration inside and outside the cell membrane is poor. Transpiration can provide transport power for the transport tissue, like a pump to the water and water carrying inorganic salts to the top of the plant. Or first through the root absorption, and then through to the transport.
Q:Does the inorganic salt affect the gpc molecular weight results?
GPC determination of molecular weight through the column when the molecular size of the molecular peak, the molecular weight of the early comparison of the peak, that is relatively large molecules in the GPC pillars can not pass, pass the molecules were detected out of the peak, This molecular weight is not absolute, since the GPC determination is actually the size of the molecule rather than the size of the molecule, and of course it is also possible to approximate the molecular weight of the molecular weight of the molecule. Large; exactly how their relationship, with GPC can not be determined, only through the standard liquid molecular weight to compare, this result is relative, not absolute.
Q:What is the risk of low inorganic salt?
Phosphorus into the body of phosphorus containing 750-800mg about 1% of body weight, mineral weight of 1/4. Of which 87.6% in the form of hydroxyapatite bone salt stored in the bones and teeth, 10% with protein, fat, sugar and other organic matter combined constitute soft tissue, the rest distributed in the muscle, skin, nerve tissue and other tissues and membranes Of the ingredients. Function Phosphorus is present in every cell of the human body, which is indispensable for bone growth, tooth development, renal function and nerve conduction. Phosphorus is a component of nucleic acids, phospholipids and certain enzymes, which promotes growth and tissue repair. It helps carbohydrate fat and protein utilization, regulates glycogen breakdown, and participates in energy metabolism. Phospholipids are the major components of the cell membrane, which are related to the permeability of the membrane. Phosphate can regulate the metabolism of vitamin D, to maintain the stability of calcium within the environment. Lack of disease  phosphorus deficiency when the mental confusion, cranial nerve palsy, transport disorders, muscle weakness, hypothyroidism, anorexia, joint stiffness, abnormal blood, urinary calcium increased. Typical cases  hyperphosphatemia, renal dysfunction, or hypoparathyroidism and hypothyroidism and other endocrine diseases can also occur. Too many symptoms  nerve excitement, tetany and convulsions. The physiological requirement of phosphorus is 12.3mg / kg / d. Calcium / phosphorus ratio in the 2: 1-1: 2 appropriate range. Food sources  food in the meat, fish, milk, beans and hard shells and other phosphorus more.
Q:How to get an inorganic salt
Inorganic salts are salts of inorganic compounds, formerly known as minerals. Plant growth needs N, P, K three elements and Ca, Zn, B, Mg, S, Fe and other trace elements. Depending on the type and amount of inorganic salts required for plant life, the water and various proportions of inorganic salts are scientifically formulated into plant nutrient solutions. The method of cultivating plants with plant nutrient solution is called soilless cultivation. The inorganic salts used to prepare the nutrient solution are generally not available for extraction, such as potassium nitrate, calcium nitrate, magnesium sulfate, potassium dihydrogen phosphate, copper sulfate, zinc sulfate and the like, and the reagent may be a chemical fertilizer. The purity of the reagent is high and the impurities of the fertilizer are more. If you can not get it, you can use soil leaching solution (fertile soil plus fresh water, the liquid obtained after filtration), which generally contains a variety of inorganic salts.
