What is the difference between upland and paddy fields? What is good to plant in the first year of c

As a land worker, dryland and paddy fields are classified as second-class land in the national standard.

In this way, the three types of land and irrigated land belong to the category of "cultivated land". Let's popularize it first:

1. Paddy field (0101): refers to the aquatic used for planting rice, lotus root, etc.

Arable land for crops. It includes cultivated land where the rotation of aquatic and xerophytic crops is practiced.

2. Dryland (0103): refers to cultivated land without irrigation facilities and mainly relies on natural precipitation to grow xerophytic crops, including cultivated land without irrigation facilities and only relying on flood diversion and siltation.

The third type of cultivated land is irrigated land (0102), which is between the above two types of land, mainly using groundwater or ditch pumping for irrigation, which is mostly seen in farmland in temperate areas. I won't explain it here.

The picture shows the use of sprinkler irrigation, which cannot be called the general sense of paddy field entry explanation is similar to it, that is, the explanation of paddy field is different: paddy field is divided into two categories according to the water source: irrigated paddy field and Wangtian field. Irrigated paddy field refers to the cultivated land that has water source guarantee and irrigation facilities, can be irrigated normally in a normal year, and is used for planting aquatic crops, including irrigated water-drought rotation land.

Wangtiantian refers to the cultivated land without irrigation engineering facilities, mainly relying on natural rainfall, for planting rice, lotus root, mat grass and other aquatic crops, including water and drought rotation land without irrigation facilities.

The picture shows the pre-wintering state of wheat, which does not belong to the "paddy field" in the general sense, and the paddy field as understood by people in the general sense is the field where the farmland has accumulated water for a certain period of time, and the dry land is the field that has not accumulated water during the entire crop planting period.

The picture shows the state of rice after transplanting, and the real sense of the "paddy field" I am from the north, North China.

Wheat and corn are the main food crops.

North China is not as good as the south, the precipitation is relatively less, and farmland irrigation mainly relies on underground well water, ditch pumping, and natural rainfall. Before wheat enters winter, it should be watered with frozen water, and it should be watered again in the spring of the next year, all of which are pumped from the ground or ditches for flood irrigation, and sprinkler irrigation is used in areas with better conditions. After the wheat is harvested, when the corn planted in the field grows to a foot high, it is watered again.

Strictly speaking, this does not belong to the concept of "paddy field", because there is no stagnant water in the field during the whole rotation period of wheat and corn, and the field with stagnant water will cause the wheat and corn to "flood the roots" and cause the roots to rot due to insufficient oxygen in the roots.

The picture shows groundwater or ditch pumping for irrigation, and the way rice is grown is clearly different from wheat: rice is "raised" before it is officially planted, and then the seedlings are inserted into a seedbed full of stagnant water by manual or mechanical means, and the entire field is waterlogged before the grains are filled with slurry. This is the true meaning of "paddy field".

Unlike paddy fields, which grow wheat, soybeans, sorghum, etc., which do not require much water, paddy fields are mainly grown with hot and water-loving rice. There is also a difference in the distribution of the two, the dry field is distributed in the north of the Qinling-Huaihe River, while the paddy field is distributed in the south of the Qinling-Huaihe River.

Paddy fields are fields that store water on the surface, and dry lands are fields that do not store water on the surface. In some places, dryland also refers to paddy fields that can be transplanted mainly by rainwater and fields that cannot be watered. Crops grown in dryland are different from paddy fields, such as wheat, soybeans, sorghum, etc.

It does not require much water, whereas rice fields are mainly cultivated with heat- and water-loving rice.

Dry land refers to land with little water and mainly crops such as sorghum and wheat are grown. Paddy field refers to land with a lot of water and is mainly used for rice cultivation.

Dry fields are mainly found in inland mountainous areas. There is basically no water source in the dry field, and if the rain is not enough in June and August, the rain time is uneven, and the rice will not grow well and there will be no harvest.

Paddy fields are distributed in places where there are water sources, and are mostly distributed in low valleys and flatlands and beside small rivers and ditches. Except in particularly rainy years, there is no shortage of water in paddy fields.

Summary. In the first year, it is best to plant shallow root crops, such as vegetables and legumes, and reapply organic fertilizer to rebuild the soil microenvironment.

In the first year, it is best to plant shallow root crops, such as vegetables and legumes, and reapply organic fertilizer to rebuild the soil microenvironment.

Is it okay to plant beans in the first year of changing paddy fields to dry fields?

The soil profile structure of paddy field is the tillage layer from top to bottom, with a thickness of about 10 to 20cm, and the bottom layer of pear is about 10 cm thick. In the first year, you can plant shallow root crops such as vegetables and beans, and then reapply organic fertilizer to rebuild the soil microenvironment.

Pro, it is okay to plant carob in the first year of paddy field to dry field, and carob is also a shallow root crop.

Dry land is arable land that relies on rainwater to grow crops such as wheat and corn; Paddy fields are cultivated land used for artificial irrigation and planting of crops such as rice; Basic farmland is the farmland that is demarcated from the cultivated land to ensure income in drought and flood and has good planting conditions as the basic farmland, which is the people's life-saving field, and it includes dry land and paddy field.

Basic farmland refers to the farmland that provides basic local food consumption, and is fixed land that cannot be forcibly expropriated, abandoned, grazing and other behaviors that destroy agricultural production. General farmland, also known as general farmland, refers to land that is mainly used to grow crops such as wheat, rice, corn, and vegetables, and is often cultivated. The main difference between basic farmland and general farmland is that basic farmland belongs to the type of cultivated land under key protection, and it shall not be occupied unless there are special circumstances, and general farmland can not be as strict as the protection of basic farmland.

Extended Materials. According to Article 2 of the Regulations on the Protection of Basic Farmland, the State implements a basic farmland protection system. The term "basic farmland" as used in these Regulations refers to cultivated land that shall not be occupied in accordance with the demand for agricultural products of the population and social and economic development in a certain period of time and on the basis of the overall land use plan.

The term "basic farmland protection zone" as used in these Regulations refers to the specific protection areas designated in accordance with the overall land use plan and in accordance with legal procedures for the purpose of carrying out special protection of basic farmland.

Cultivated land other than basic farmland and vegetable fields.

Basic farmland is a special farmland that is subject to national key protection.

The vegetable field is a special vegetable production field, which belongs to the farmland with good soil quality.

Except for these two, the others belong to general farmland.

General farmland is cultivated land other than the basic farmland that has been demarcated, which can develop the forestry and fruit industry; After approval, it can also be used for aquaculture and facility planting; It can also be planned as a conditional built-up area, etc.

Hello, dear, the conversion of dry land to paddy field and dry land to paddy field are two different ways of farmland transformation, and the difference between them mainly lies in the purpose and method of transformation. 1.Conversion of dryland to paddy fields:

Conversion of dryland to paddy fields is the conversion of land originally used for dryland agriculture into paddy fields to accommodate the cultivation of aquatic crops such as rice. This kind of belt transformation usually requires the construction of water conservancy facilities, such as water diversion channels, reservoirs, water pumps, etc., to ensure that paddy fields can obtain sufficient water sources for early pulse irrigation. In addition, soil improvement and paddy field management are needed to provide a suitable growing environment.

2.Conversion of dry land to paddy field: Conversion of dry land to paddy field is the transformation of land originally used for dry farming into dry land to accommodate the cultivation of other crops, such as wheat and corn.

This type of retrofitting usually requires soil improvement and drainage systems to ensure that the soil is well drained and that water accumulation can lead to poor crop growth or disease. In general, the difference between dryland to paddy field and dryland to paddy field is the purpose and method of transformation. Conversion of dry land into paddy field is the transformation of dry land into paddy field suitable for the cultivation of aquatic crops, while conversion of dry land into dry land suitable for the cultivation of other crops.
