What kind of soil conditions can I grow rice? What should I be aware of?

The soil is very soft, the water quality of the soil is relatively large, there is a lot of water, the conditions are relatively good, not particularly hot. It is necessary to pay attention to the way of planting, as well as the process of planting yourself, to pay attention to fertilization, and to pay attention to the way of transplanting seedlings even if it is prevented.

Sandy soils or clay soils are fine. Pay attention to the pH of the soil, and also pay attention to the moisture of the soil, never let the soil dry too much, and do not expose it to the sun for a long time.

As long as the soil is not deficient in boron fertilizer in the 1st area, these lands can be used for continuous cropping of rapeseed and rice. The excessive element of boron fertilizer is an important reason why oil rice cannot be continuously cropped.

2. There are still certain precautions for the field of hybrid rape and rice continuous cropping, and many places have found a lot of problems in the continuous cropping of rape and rice. Some rape stubble will be found to be diseased after planting rice, and the problem is caused by improper fertilization by some people in the previous crops.

Rice is a very important food crop for our people, and it can be said to be the main food, so the state also attaches great importance to it. When farmers in our country grow rice, it does not mean that they have fields at the beginning, but also that they slowly reclaim them. When cultivating rice fields, it is necessary to choose the right soil first, so as to ensure that the rice is profitable.

In general, the kind of white clay soil or black soil and chernozem soil are more suitable for growing rice. <>

People usually like to buy Northeast rice when they buy rice, because the land in Northeast China is indeed very suitable for growing rice, and the rice grown is long and delicious. The climate in the northeast is relatively humid, and white clay is widely distributed there, especially in the eastern part of Heilongjiang and the eastern part of Jilin Province. The terrain is generally flat, so the soil structure is ideal for growing rice, and the surface of this soil is dark, but the bottom is white.

However, because many rice farmers in China are not very familiar with the soil, it is necessary to carry out trial planting before planting rice. <>

China's land can be roughly divided into three types, black soil, red soil, and yellow soil, the yellow soil is relatively the most barren, the red soil is generally distributed in the southern region of China, and the black soil is the most fertile, so the black soil is also very suitable for growing rice. Black soil is the most fertile soil, and most crops can survive in black soil, so growing rice is no problem. Black soil is also a kind of land that is relatively easy to distinguish, and the whole is black, so many people feel that if they find a piece of black soil, they will simply find a cornucopia.

The most obvious feature of chernozem is that there are calcium carbonate in different parts of the soil, but the water retention performance of the soil is relatively poor, and it is prone to drought. Therefore, the general grass mat black cover soil is more suitable for planting rice, the organic matter in this soil accumulates more, the upper layer of the soil is black or gray-black, and there is very fertile humus, and the lower layer has a lot of calcium deposits.

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.

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 aeration and permeability, moderate fertilizer supply and fertilizer retention capacity, drought and waterlogging resistance, strong stress resistance, wide adaptability, long tillage period, and easy to cultivate into high-yield and stable-yield soil.

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 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 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.

1.Distribution of rice. China is a big agricultural country, a well-known agricultural country abroad, and rice is one of the most historically significant food crops in China.

China's rice is bounded by the Qinling Mountains and the Zhun River, and is divided into two rice areas, the south and the north, and the southern rice area accounts for more than 90% of the country's area. According to the characteristics of natural conditions, variety types, cultivation systems and other characteristics, the country is divided into six rice cultivation belts, namely, the double cropping rice belt in South China, the single and double cropping fold belt in Central China, the rice belt in the Southwest Plateau, the early maturing rice belt in Northeast China, the single cropping rice belt in North China and the dry rice belt in Northwest China.

2.Take a typical area as an example. Ningxia in China belongs to the dry rice belt in the northwest. All the rice in Ningxia is distributed in the Yellow River irrigation area, with Zhongwei, Zhongning, Qingtongxia, Litong and Lingwu. Yongning, Yinchuan suburbs, Helan and Pingluo are the mainstays.

3.Next, let's talk about the necessary conditions for rice cultivation. The main conditions for growing rice are water quantity and temperature.

4.In terms of water quantity, we talk about it from two directions: one is the water demand of rice itself, and the other is the natural precipitation, which determines whether rice can be planted in rice planting.

During rice growth, foliar transpiration, interplant evaporation and underground seepage are collectively referred to as the water requirement of the paddy field, and the former two are collectively referred to as the take-off capacity of the paddy field. The ratio of the amount of rice field to the amount of rainfall is called the dryness of the rice field, and the dryness is greater than 1, indicating that the natural precipitation in the area is not enough to provide the growth of the same area of rice field, and artificial irrigation is needed to meet the growth needs of rice. The northern regions, including Ningxia, have a dryness greater than 6 and must have sufficient water sources for artificial irrigation to grow rice.

5.Rice is a temperature-loving crop and needs an average daily temperature of more than 10 to start growing actively. Generally speaking, the month when the average daily temperature is above 10 is called the growing season of rice.

Generally, the rice in the growing season will grow faster than other stages, and the growth and development in the plant will be faster than other stages, and seizing this stage will lay a good foundation for a bumper rice harvest.

To choose a relatively moist soil, to choose the soil with relatively large moisture in the soil for planting, most of the rice is distributed in the southern region, when planting, we must plant the planting density of rice, but also pay attention to the depth of rice planting.

Most of them are planted on both sides of the river, where there is plenty of water, and it is related to the river.

The soil environment must be good, the varieties must be excellent, organic fertilizer should be applied, and precision tillage; Organic rice is suitable for growing in saline-alkali land, and is resistant to high temperatures, as long as it has strong water retention and fertilizer retention capacity.

When organic rice is planted, the requirements for the soil are relatively high, try to choose loose and fertile soil, and the yield of rice is relatively high in the soil with high organic matter content.

The planting conditions of organic rice are similar to those of ordinary rice, except that organic rice is specially cultivated, and there are no excessive requirements for soil.
