If the greenhouse soil turns red and wants to be conditioned, how should it be conditioned?

For the soil with too much acidity, 50-60 kg of lime can be applied per mu every year, and enough farm fertilizer can be applied, and only lime should not be applied without rotting farm fertilizer, so that the soil will become yellow and thin, and 40-50 kg of grass ash can also be applied to neutralize soil acidity and better adjust the water and fertilizer condition of the soil.

Through the chelation of organic substances, the mobility of soil salt separators can be increased, the concentration of soil salt separators can be reduced, and the redness of soil surface can be solved from the source.

I think it's better to put a little fertilizer in the soil and turn it over to make sure that the soil is evenly balanced.

High-quality amendments can be used to add nutrients to the soil, so that the reddened soil can be adjusted after a long period of cultivation.

Generally, it is necessary to have more fertile soil, as well as some better plants, which can actually make the soil more ruddy and promote development.

Ban chemical fertilizers, and increase the application of organic biological fertilizers, especially straw organic fertilizers. It can not only reduce the appearance of harmful cations, but also consume nitrogen in the topsoil during the decomposition process, reduce the excessive accumulation of nitrate nitrogen, and increase the buffering effect of soil.

Hello, how to regulate the red soil of the greenhouse: 1. Reduce soil evaporation: use drip irrigation or break the bottom layer of the plough (that is, the soil is deep turning), or remove the greenhouse film in the summer shade to reduce the coarse number and low evaporation, reduce the dissolution and evaporation of soil salt separators, reduce the movement of salt separators to the soil surface, and reduce soil evaporation after deep ploughing.

Peel off the canopy film in summer. 2. Adjust soil pH: acidic soil is applied alkaline substances such as plant ash, quicklime and other alkaline substances to increase soil pH.

Alkaline soil is applied with acidic substances such as gypsum and ferrous sulfate to reduce the solubility of soil ions: by adding some chelating agents, the solubility of soil ions is increased, and in the case of irrigation, the salt separators move to the depth of the soil with the water, reducing the collection of salt separators on the soil surface. 4. Reasonable fertilization

Organic fertilizer, bacterial fertilizer, and microbial fertilizer are applied to improve the soil physical and chemical environment. Hope it helps.

Summary. Hello dear! How to improve the soil of the greenhouse if it turns red?

1.

Adjust soil pH:

Acidic soil application of alkaline substances such as plant ash, quicklime and other alkaline substances to increase soil pH. Alkaline soil is applied with gypsum, ferrous sulfate and other acidic substances to reduce soil pH. 3. Adjust ion solubility

By adding some chelating agent to increase the solubility of soil ions, in the case of irrigation, the salt separators move with the water to the depth of the soil, reducing the collection of salt separators on the soil surface. 4. Reasonable fertilization: apply organic fertilizer, bacterial fertilizer and bacterial fertilizer to improve the soil physical and chemical environment.

How to improve the soil of the greenhouse if it turns red?

Hello dear! How should the old Weiqin talk about the reddening of the greenhouse soil? 1. Reduce soil evaporation

Drip irrigation is used to break the bottom layer of the plough (i.e., the soil is turned deeply), or the greenhouse film is removed in summer to reduce the evaporation rate, reduce the dissolution and evaporation of soil salt separators, and reduce the movement of salt separators to the soil surface. 2. Adjust soil pH: Acidic soil is covered with alkaline substances such as plant ash and quicklime to increase soil pH.

Alkaline soil is applied with gypsum, ferrous sulfate and other acidic substances to reduce soil pH. 3. Adjust the solubility of ions: by adding some chelating agents, increase the solubility of soil ions, and in the case of irrigation, the salt separators move to the depth of the soil with the water, reducing the collection of salt separators on the soil surface.

4. Reasonable fertilization: apply organic fertilizer, bacterial fertilizer and bacterial fertilizer to improve the soil physical and chemical environment.

There are three major factors for greenhouse soil to turn red: 1. Soil acidification: in some places, the initial soil is alkaline soil, and long-term application of chemical fertilizers makes the soil pH between, resulting in soil acidification, and iron, manganese and zinc plasma in the soil dissolve and collect the soil surface, and the iron and manganese plasma are oxidized to generate red patches after the soil dries.

This soil is acidic. 2. Soil salinization: the process in which the salt of the bottom layer of the soil or groundwater rises to the surface with the capillary water, and the salt accumulates in the surface soil after the water evaporates.

This soil is generally alkaline and has a pH. 3. Soil eutrophication: the soil isolates of T. salinus are collected on the surface of the soil, which makes the nutrients on the soil surface too high, which is suitable for the survival of some algae, and when the soil surface is dry, the algae die, and the algae residues show red.

Summary. Hello dear, happy to answer for you. Crop rotation is possible:

For our conditional planting, we should pay attention to reasonable crop rotation when planting, which can effectively alleviate the nutrient imbalance caused by heavy cropping. In addition, for plots with a relatively long stubble period, our growers can plant crops with strong fertilizer absorption capacity Heavy stubble soil should be increased with organic fertilizer and trace elements. Treat bacteria with bacteria and supplement trace elements.

Adjust acid and supplement calcium, sprinkle quicklime, plant ash, etc. If I'm helpful to you, please please give it a thumbs up, and I wish you a happy life!

Improve the soil can not be watered a lot, yes, not too much. Otherwise, it will affect the soil air permeability.

1. The surface of the soil in the greenhouse becomes red, mainly because the greenhouse vegetables are fertilized too much, and the fertilizer residues accumulate, resulting in soil salinization, so that sulfide, sulfate, organic salt, and inorganic salts remain in the cultivated soil, resulting in soil compaction and salinization of the greenhouse. As a result, a purplish-red substance appears on the surface of the soil.

2. Improvement measures:

1) Carry out grain and vegetable rotation, and the rotation of greenhouse vegetables and rice can be carried out in places where conditions permit; In summer, especially in the rainy season, the roof membrane of the greenhouse is removed, and the natural rainwater is used to wash the salt.

2) Carry out balanced formula fertilization to avoid excessive fertilization; Increase the application of organic fertilizer, chicken manure and pig manure, return straw to the field, and reduce the application of chemical fertilizer; Minimize the use of organic fertilizers with high salt content and chlorine-containing fertilizers.

3) remove 2 3 cm of soil on the surface layer of greenhouse soil, replace it with fertile soil, and change the soil to remove salt; Improving the soil structure and activating the soil is not only conducive to the extension of the lateral roots of vegetables in greenhouses, but also enhances the ability of vegetable roots to absorb nutrients and water, and can also improve the organic matter content of greenhouse soil.
