What soil is suitable for rice? Rice is suitable for clayey or loam

The nature of rice soil is between sandy soil and clay soil, and its tillage and fertility are better. The contradiction between water and air is not so strong in this kind of soil, it is aeration and permeability, has moderate fertilizer supply and fertilizer retention capacity, drought and waterlogging resistance, strong stress resistance, wide adaptability, long tillage period, and is easy to cultivate into high-yield and stable-yield soil.

Rice is suitable for growing clay soil rich in nitrogen, phosphorus and potassium, which can keep the rice field with water and the rice seedling field not dry up, which is conducive to the growth of rice. Control the moisture in the later stage to prevent rice lodging.

The pH of the soil that is most suitable for rice is 6-7. The properties of suitable rice soil should be between sandy soil and clay soil, and its tillage and fertility should be better. The soil of this texture is aerated and permeable, and the fertilizer supply and fertilizer retention capacity is moderate.

The most suitable soil for rice growth is called paddy soil, which is a kind of artificially purified cultivated soil, as long as irrigation is convenient, any kind of soil can be transformed into paddy soil.

Rice is suitable for clay soils. Sandy soil should be planted with crops with short growth period, barrenness tolerance, loose soil and good drainage, such as potatoes, peanuts, sesame, watermelons, fruit trees and other crops. Clayey soil is suitable for crops with long growth period and large fertilizer requirements, such as rice, wheat, sorghum, corn, beans, etc.

Loam soils are suitable for growing a variety of crops and are ideal soil textures.

Rice is clayey soil, cotton and millet are loam, and peanuts are sandy soil. There are generally few earthworms in sandy soils, because earthworms like to live in soils rich in organic matter, sandy soils have little organic matter, clayey soils and loam soils are more suitable for earthworms to live, but require organic matter such as rotten leaves and a shady environment. Clayey soils with very little sand and clayey soils.

The sandy soil is loose, the soil layer is deep, and it contains uniform sand grains. The nature of loam is between sandy and clay, and its tillage and fertility are better.

When growing rice, you need to know the conditions in which it is grown. So what are the conditions for growing rice? The following is a list of the soil conditions for rice cultivation that I have carefully sorted out for you, so let's take a look.

First, the soil conditions for growing rice.

1) A certain depth and soft tillage layer: the growth and development of the aboveground part and the underground part of rice are mutually restricted. In order to achieve high yields, the roots of the underground part must be sufficiently grown and have a strong capacity to absorb fertilizers.

2) Maintain a certain water layer: Rice is a hydrophilic crop, and a certain water layer environment can not only ensure the water demand of rice itself, maintain the soft state of the soil, and stabilize the redox potential of the soil. The soil has a layer of water that inhibits the growth of xerophytes and wet weeds.

3) Horizon: Since the depth of the water layer is often changed during the rice growth period, the field level can accurately control the depth of the water layer, create the same soil environment for each rice plant, and make the rice grow neatly and evenly. Generally, the field height difference is not more than 3cm.

Second, the type of rice.

1) According to the origin, it is divided into indica rice and japonica rice. (Indica rice is suitable for cultivation in low-latitude, low-latitude humid and hot areas.) Grains are easy to fall off, resistant to moisture, heat, and strong light, but not cold. Japonica rice is the opposite).

2) According to the adaptability and drought resistance of the varieties to soil moisture, they were divided into rice and upland rice. According to the length of the growth period, it is divided into early-maturing varieties, medium-maturing varieties and late-maturing varieties.

Third, ** rice is infected with rice blast.

1) Start clearing the pathogen**. After the rice harvest last year, the rice in the field should be cleaned as much as possible, especially where rice blast occurred. Not only do you have to clear the fields, but you also have to avoid the roadsides. The first is to reduce the occurrence of diseases at the source.

2) Pay attention to sunny fields. Sunlight fields play an important role in the growth of rice (provided that there are water pipes). Depending on the field conditions, the time of drying the land is also different.

Under normal circumstances, 5-8 days is good, but it is also acceptable. It's been a lot of times.

3) Reasonable fertilization, in addition to nitrogen fertilizer (no longer applied), phosphate fertilizer, potassium fertilizer is also applied continuously, in addition to supplementing medium and trace elements, such as iron, manganese, copper, zinc, boron, etc., add medium and trace elements when preventing insects and diseases. Elemental foliar fertilizer is better and can also be applied alone.

First of all, be sure to have plenty of water. Rice cultivation is actually simple and not simple, but the requirements for soil moisture are very high. If there is a slight drought, it will have a great impact on the yield and quality of rice.

First of all, we need to choose very fertile soil, try to choose sandy soil, we need to balance the acidity and alkalinity of the soil, and then we also need to spray pesticides in time, regularly remove insect pests, ensure soil permeability, loosen soil in time, and strengthen the management of water and fertilizer.

The soil types that are suitable for growing rice are as follows:

The most suitable soil for rice growth is between sandy soil and clay soil, because this kind of soil is not only fertile, but also high cultivability, the contradiction between water and air inside is not prominent, nor strong, it can be said that it is both breathable and permeable, and can have strong cold resistance, once the rice is sown, it can ensure that this piece of land is stable and high yield for a long time.

White clay soil is mainly distributed in the relatively humid climate area of Northeast China, mainly located in the eastern part of Heilongjiang and Jilin provinces, and the subtypes include white clay soil, meadow white clay soil and latent white clay soil. Among them, meadow white clay soil and latent white clay soil are most suitable for the development and planting of paddy fields due to the flat terrain and the characteristics of the structure of the body.

The black soil is divided into four subcategories: black soil, meadow black soil, white slurry black soil and surface latent black soil, the black soil on the black soil has high organic matter content and rich soil, especially in the area where the black soil is relatively rich, its climate, temperature and rainfall are quite suitable, suitable for rice planting and growth. Before planting rice, the northerners are accustomed to using black soil to configure the nutrient soil of rice, and after careful screening and removal of impurities, the black soil with a certain proportion of acidifiers can generate high-quality nutrient soil, which can not only ensure the initial conditions for rice growth, but also prevent the appearance of insect pests to a certain extent.

Chernozem can be divided into four subcategories: chernozem, leaching chernozem, calcareous chernozem, and meadow chernozem, according to the landform, water conditions and degree of carbonate leaching. Chernozem soil is characterized by the accumulation of calcium carbonate in different parts of the soil, and the soil has poor water retention and is prone to drought. Meadow chernozem can be used for irrigation and rice cultivation.

Meadow soil is a non-zonal soil, which can be divided into meadow soil, latent meadow soil, white pulp meadow soil, and calcareous meadow soil. Meadow soil is the most fertile soil for growing rice.

Marsh soils are also non-zonal soils, which develop in low-lying waterlogged areas in zonal soil areas, and in northern mountainous areas where the soil is heavy and the seasonal permafrost exists for a long time. Under the condition of drainage projects, peat swamp soil and meadow swamp soil can be reclaimed for rice planting.

Paddy soil, the rice planting year in cold areas is not long, the attributes and characteristics of paddy soil have not yet been formed, most of them belong to transitional soils, according to the formation and development characteristics of each soil genus, can belong to the subcategory of submerged and latent paddy soils. It is characterized by an enhanced trend towards the release of nutrients, ** and the absorption of nutrients by the plant.
