In recent years, newly built protected area greenhouses have sprung up like mushrooms, mainly in three forms: steel frame structure arch shed, three-sided earthen wall greenhouse and three-sided steel structure greenhouse.
Good soil can be high yield, how to adjust the soil in the new greenhouse? Soil, fungi and organic matter are indispensable. The raw soil or field soil in the shed can be scientifically conditioned to meet the needs of the growth of shed crops.
<h1>First, soil</h1>
The soil is composed of solid, liquid and gas phases, and is composed of the interaction of air, water, minerals and organic matter. Air and water each account for 20-30%, minerals for 38%, and organic matter for 12%.
Soil is divided into three types: sandy soil, clay soil and loam soil. Depending on the color of the soil, there are laterite, black, loess, green and white soil.
Greenhouse crops are suitable for loam soil, and the combination of loam and sandy soil is suitable for most crops.
<h1>2. Microorganisms</h1>
Greenhouse crops have long planting cycles, and microorganisms are the "engineers" of soil ecosystems.
A healthy soil agrarian structure is the basis for crop growth. Microorganisms and soil aggregates are inextricably linked. On the one hand, soil agglomerates are the place where microorganisms exist; on the other hand, soil microorganisms are important biological factors in the formation of soil aggregates.
Before planting and planting process supplements, such as EM bacteria, Bacillus, yeast, Trichoderma, etc. There are many biocontrol bacteria with both fertilizer and pesticide effects, and biocontrol microbial bacteria mainly have the following categories.
Fungi Such as Trichoderma, yeast, mycorrhizal, Purple Purple, Bulbophyllum pachycetes, etc.
Bacteria such as Bacillus, Pseudomonas, Agrobacterium and Pasteurella. Some Bacillus have inhibitory effects on nematodes, such as Bacillus auriculata.
Actinomycetes Streptomyces and its variants.
<h1>3. Organic matter</h1>
Greenhouse soil crops require a large amount of organic matter, soil organic matter content is one of the important factors of crop yield and quality, supplementing soil organic matter is a very critical agricultural operation activity. Fruits such as strawberries, cherries and grapes to improve taste quality require rich soil organic fertilizers.
In recent years, the direct application of fermented soybeans is a good way to improve the lack of organic matter in the soil and improve the quality of agricultural products.
Organic matter is derived from organic fertilizer, and the current agricultural production of organic fertilizer raw materials is roughly divided into six categories:
1. Straw Crop straw, such as corn, wheat, rice, fresh vegetable straw, etc.
2. Green manure Common green manure varieties in the northern region include mung beans, peas, clover, alfalfa, etc. of the legume family; winter rape and February orchid (also known as Zhuge cabbage) of the cruciferous family; rye grass and rat thatch grass of the grass family; amaranth and chicory of the amaranth family. The green manure varieties in the southern region include broad beans, amaranth (also known as nest vegetables), green ping (also known as manjiang red), purple cloud ying (also known as safflower grass) and so on. This kind of green fertilizer belongs to clean natural high-quality organic fertilizer.
3. Cake fat or glucuroal residue Cake fat (including soybean cake, rapeseed cake, cottonseed cake, sesame cake, castor cake, tea seed cake, etc.), mushroom residue, glycolaldehyde residue.
4. Peat and humic acid peat (also known as grass charcoal, peat), humic acid (including primary and regenerated humic acid). For example, grass charcoal soil is widely used in vegetables, strawberry seedlings or elevated three-dimensional cultivation.
5. Marine flora and fauna (fish, shrimp, crabs, shellfish, etc.), plants (seaweed, seagrass) and minerals (sea mud). Fish protein, chitin, seaweed extract, etc. are being accepted by the majority of growers by using marine animals and plants to enhance crop stress resistance, improve fruit quality and improve and repair soil.
6. Other types of silt (unstained beams) of rivers, ponds and lakes, municipal waste (domestic garbage, sludge) and fly ash (solid waste of thermal power industry).
