Problems solved by technology

[0004] 1) The quality and effect of fertilization are greatly affected by the amount of watering. When the watering is insufficient, the concentration of the fertilizer solution is too high, which is prone to fertilizer damage, and it is also easy to cause the concentration of surface salt to be too high, causing salt damage to the soil. In addition, insufficient watering When the fertilization depth is shallow, it is also not conducive to absorption and utilization; when the amount of water is too large, the nutrients in the fertilizer will be lost more, and the waste will be serious
[0005] 2) When fertilizing with volatile fertilizer, it is easy to increase the concentration of harmful gases in the protected area after fertilization, causing poisoning of harmful gases
[0006] 3) The uniformity of fertilization is relatively poor. Usually, due to the influence of water flow, the amount of fertilizer left at the water inlet is relatively small, and the middle and lower parts of the furrow are relatively large due to the accumulation of fertilizer.
[0007] The existing flush fertilization generally has problems such as low plant absorption and utilization rate

Embodiment 1

[0023] A kind of fertilization for greenhouses, which is composed of the following components by weight:

[0024] 1 part of ammonium bicarbonate, 2 parts of charcoal ash, and the balance is water, and water accounts for 25% of the total weight.

[0025] Charcoal ash is the white or off-white substance left after charcoal is burned with oxygen or in the air. The active ingredient is potassium carbonate.

[0026] The invention is particularly suitable for application when the seedling height of greenhouse vegetables and melon and fruit crops is about 1m in the early stage.

[0027] The usage method of the present invention:

[0028] Mix the components of the formula amount for later use, and dilute with water when using, and the dosage is 15g / m 2 .

Embodiment 2

[0030] A kind of fertilization for greenhouses, which is composed of the following components by weight:

[0031] 1 part of ammonium bicarbonate, 3 parts of pulverized coal, and the balance is water, which accounts for 20% of the total weight.

[0032] Charcoal ash is the white or off-white substance left after charcoal is burned with oxygen or in the air. The active ingredient is potassium carbonate.

[0033] The particle diameter of pulverized coal is 50 μm.

[0034] The invention is particularly suitable for application when the seedling height of greenhouse vegetables and melon and fruit crops is about 1m in the early stage.

[0035] The usage method of the present invention:

[0036] Mix the components of the formula amount for later use, and dilute with water when using, the dosage is 7.5g / m 2 .

Embodiment 3

[0038] A kind of fertilization for greenhouses, which is composed of the following components by weight:

[0039] 1 part of ammonium bicarbonate, 2 parts of charcoal ash, and the balance is water, and water accounts for 30% of the total weight.

[0040] Charcoal ash is the white or off-white substance left after charcoal is burned with oxygen or in the air. The active ingredient is potassium carbonate.

[0041] The invention is particularly suitable for application when the seedling height of greenhouse vegetables and melon and fruit crops is about 1m in the early stage.

[0042] The usage method of the present invention:

[0043] Mix the components of the formula amount for later use, and dilute with water when using, and the dosage is 30g / m 2 .

Abstract

The invention discloses a water flush fertilizer for greenhouses, which is characterized by being composed of the following components in part by weight: 1 part of ammonium bicarbonate, 1-3 parts of ash wood or pulverized coal and the balance of water, wherein the weight of the water accounts for 20-30% of the total weight of the water flush fertilizer. The water flush fertilizer disclosed by the invention is simple in formula and convenient to use, and can effectively promote the production increasing of vegetables, melons and fruits. The main composition of the water flush fertilizer disclosed by the invention is alkalescent ammonium bicarbonate, and through the utilization of a water-flush method, the acid-base property of soil can be adjusted, the soil conditions can be improved, and the growth of crops can be promoted.

Description

technical field [0001] The invention relates to a kind of flush fertilization for greenhouse. Background technique [0002] Flush fertilization is a kind of water-soluble fertilizer, which is used with irrigation and belongs to topdressing fertilization. Flush fertilization has many advantages, such as: simple application method, no damage to the roots and stems of crops, uniform fertilizer application, etc. [0003] However, the disadvantages of flush fertilization are also obvious: [0004] 1) The quality and effect of fertilization are greatly affected by the amount of watering. When the watering is insufficient, the concentration of the fertilizer solution is too high, which is prone to fertilizer damage, and it is also easy to cause the concentration of surface salt to be too high, causing salt damage to the soil. In addition, insufficient watering When the fertilization depth is shallow, it is not conducive to absorption and utilization; when the amount of watering i...
