Compound and method capable of maintaining phosphorus concentration balance in rice field soil

Abstract

The invention discloses a compound and a method capable of maintaining phosphorus concentration balance in a rice field soil. The compound comprises a plurality of capsules and a plurality of active holes formed in the outer walls of the capsules, the plurality of capsules are put into a compound fertilizer to be mixed, the plurality of capsules comprise A nitrogen element capsules, B phosphorus element capsules and C potassium element capsules, and a nitrogen-rich base material is contained in the nitrogen element capsule, wherein the phosphorus element capsule comprises a phosphorus-rich base material, the potassium element capsule comprises a potassium-rich base material, and the ratio of A: B: C can be adjusted; an active film is arranged on the active hole and passes through a free ion ionization dissociation chain in the soil; and the base material in the unchained capsule flows into the compound fertilizer from the active holes to supplement the corresponding element concentration, thereby achieving the element concentration balance.

Description

technical field [0001] The invention relates to a compound, in particular to a compound and a method capable of maintaining the balance of phosphorus concentration in paddy field soil. Background technique [0002] The nutrients absorbed by crops must be in a dissolved state, that is, when chemical fertilizers are applied to the soil, the nutrients are in the state of ions or molecules, which can be dissolved in the water in the soil or in the weak acid secreted by the roots of the crops, and absorbed by the crops, while the phosphorus in the soil Most of them are insoluble or poorly soluble phosphorus, which is not easy to be absorbed by crops. The traditional method of improving the utilization rate of phosphorus fertilizer in paddy fields needs to be converted into water-soluble phosphorus compounds that are easily absorbed by crops through chemical processing. During the chemical processing process, it is easy to cause the loss of effective elements of phosphorus fertiliz...

[0002] The nutrients absorbed by crops must be in a dissolved state, that is, when chemical fertilizers are applied to the soil, the nutrients are in the state of ions or molecules, which can be dissolved in the water in the soil or in the weak acid secreted by the roots of the crops, and absorbed by the crops, while the phosphorus in the soil Most of them are insoluble or poorly soluble phosphorus, which is not easy to be absorbed by crops. The traditional method of improving the utilization rate of phosphorus fertilizer in paddy fields needs to be converted into water-soluble phosphorus compounds that are easily absorbed by crops through chemical processing. During the chemical processing process, it is easy to cause the loss of effective elements of phosphorus fertilizer. Loss or decomposition, the traditional method only adds phosphorus element alone. When the crop absorbs part of the phosphorus element, the phosphorus element is out of balance and replenishes phosphorus. At the same time, there is no corresponding supplement of N and K element concentrations, and the phosphorus element concentration in the soil cannot The relative balance of phosphorus causes an imbalance in the concentration of phosphorus, and the yield of crops decreases.
