Read the absorption principle of 11 elements in 1 minutes
Detailed
nitrogen
Nitrate is readily absorbed when the pH is low
In the case of high PH, ammonium nitrogen is relatively easy to absorb;
Excessive potassium and phosphorus affect the absorption of nitrogen;
Boron deficiency is not conducive to the absorption of nitrogen.
phosphorus
The increase of zinc can reduce the absorption of phosphorus;
Nitrogen is not conducive to phosphorus absorption;
Iron also has an antagonistic effect on phosphorus uptake;
By adding lime, phosphorus can not be given;
Magnesium can promote the absorption of phosphorus.
The absorption efficiency of P and Mg fertilizer is better.
potassium
Boron is added to promote potassium absorption;
Zinc can reduce the absorption of potassium;
Nitrogen is not conducive to potassium absorption;
Calcium and magnesium have an antagonistic effect on potassium absorption.
Therefore, the effect of using boron containing potash fertilizer is better than that of pure potassium fertilizer.
calcium
Potassium affects calcium absorption and reduces levels of calcium nutrition;
Magnesium affects the transport of calcium, and magnesium has an antagonistic effect with calcium;
Ammonium salt can reduce the absorption of calcium and reduce the transfer of calcium to the fruit;
The application of sodium and sulfur can also reduce the absorption of calcium;
Increasing the amount of aluminum, manganese, and nitrogen in the soil also reduces the absorption of calcium.
A little amount of boron can promote the absorption of calcium.
magnesium
Potassium affects magnesium absorption;
A large amount of sodium and phosphorus are detrimental to magnesium absorption;
Nitrogen can cause magnesium deficiency;
Magnesium and calcium, potassium, ammonium, hydrogen have an antagonistic effect, the use of sulfate can cause magnesium deficiency;
Magnesium can eliminate the poison of calcium.
Lack of magnesium can lead to zinc deficiency and manganese deficiency.
Magnesium and zinc have a mutual promoting effect.
iron
Boron affects the absorption of iron and reduces iron content in plants;
Nitrate nitrogen influences iron absorption;
Vanadium and iron have antagonistic effects;
There are many elements that cause iron deficiency, and their arrangement order is Ni > Cu > Co > Gr > Zn > Mo > Mn;
Potassium deficiency can cause iron deficiency;
Large amounts of nitrogen, phosphorus and calcium can cause iron deficiency.
boron
Oxides of iron and aluminum can cause boron deficiency;
The hydroxides of aluminum, magnesium, calcium, potassium, and sodium can cause boron deficiency;
The lack of nitrogen, phosphorus, potassium and iron for a long time can lead to boron deficiency;
Increasing potassium can aggravate the deficiency of boron, which results in the poisoning of a small amount of boron;
The amount of nitrogen increases and the amount of boron needs to be increased, which leads to the deficiency of boron.
Manganese is disadvantageous to Boron Absorption, and the plant needs proper Ca/B and K / B ratio (e.g., Ca / B of grape strain is 1234 mg / kg, K / B is 1142 mg equivalent). And the appropriate Ca / Mg ratio.
Boron has a controlling effect on Ca / Mg and Ca / K ratio.
Several elements that form complexes, such as strontium, aluminum, and germanium, have temporarily improved the effect of boron deficiency.
manganese
Calcium, zinc and iron hinder the absorption of manganese;
The iron hydroxide causes manganese to precipitate;
Apply physiological alkaline fertilizer to make manganese immobilized;
Vanadium can slow down the toxicity of manganese.
Sulfur and chlorine can increase the released and available manganese, which is beneficial to the absorption of manganese;
Copper is unfavorable to the absorption of manganese.
aluminum
Nitrate nitrogen is beneficial to the absorption of molybdenum, and ammonia nitrogen is not conducive to the absorption of molybdenum;
Sulfate is not conducive to the absorption of molybdenum;
Large amounts of calcium, aluminum, lead, and iron, copper, and manganese all hinder the absorption of molybdenum;
In the state of lack of phosphorus and sulfur, molybdenum is bound to lack; phosphorus needs more molybdenum for many times; therefore, excessive phosphorus can sometimes lead to the lack of molybdenum.
The increase of phosphorus is beneficial to molybdenum absorption, but the increase of sulfur is disadvantageous;
zinc
The formation of zinc, hydroxides, carbonates, and phosphates is not allowed.
The plant requires an appropriate P / Zn ratio (usually 100~120, greater than 250 zinc deficiency). Excessive phosphorus results in zinc deficiency;
Nitrogen needs more zinc for a long time, and sometimes leads to zinc deficiency. Nitrate nitrogen is beneficial to the absorption of zinc, and ammonia nitrogen is not conducive to the absorption of zinc;
Potassium and calcium increase the absorption of zinc;
Manganese, copper and molybdenum are disadvantageous to the absorption of zinc. Magnesium and zinc have the effect of mutual absorption;
Zinc deficiency results in less potassium in roots;
The clay with low Si / Mg ratio in soil will lack Zn, and zinc can resist the absorption of iron.
copper
The application of physiological acid nitrogen or potassium fertilizer can improve the activity of copper, and it is beneficial to absorption. The nitrogen is also not conducive to the absorption of copper for a long time;
Copper phosphates, carbonates and hydroxides, which are responsible for the absorption of copper, are therefore rich in Co2, carbonate and calcium rich soils, which are detrimental to copper absorption;
Phosphorus can lead to copper.
The soil generates H2S and hinders copper absorption;
Copper is also antagonistic to aluminum, iron, zinc and manganese.
