How to carry out spring ploughing What is spring ploughing and preparation

Expert: We should be "prepared", and only by preparing fertilizer can we lay the material foundation for a good harvest of the year. There are three main contents in formulating a fertilization plan:

1.It is necessary to clarify the crops planted this year, the sowing area of each crop, the type of base fertilizer, top dressing, fertilization period, fertilizer amount, etc.; 2.Estimate the demand for fertilizer and the cost of funds accordingly; 3.

Expert: Actually, it is not difficult, there are many kinds of fertilizers, but the fertilizer demand of a crop is basically stable, which can be used as the basis for fertilizer preparation. For example, for field crops, nitrogen (N) 8 15 kg per acre of land needs to be applied, phosphorus (P2O5) is not more than half of nitrogen, potassium (K2O) is mostly between nitrogen and phosphorus levels, and it may be lower in the north and higher in the south, depending on the specific soil and crop.

It's simple, just remember a conversion formula: fertilizer application rate Nutrient application amount Fertilizer nutrient content where the fertilizer nutrient content has been indicated on the fertilizer bag. For example, the total amount of fertilizer required per mu of a certain rice:

Nitrogen (N) 12 kg, phosphorus (P2O5) 5 kg, potassium (K2O) 8 kg. How do you convert it into urea, superphosphate and potassium chloride rates? The specific algorithm is:

urea application rate 12 46% 26 kg; Superphosphate application rate 5 15% 33 kg; Potassium chloride application rate 8 60% 13 kg.

What we usually say about spring plowing refers to the spring planting of rice.

1. In terms of timing. From the perspective of the climate of the middle and lower reaches of the Yangtze River plain, planting a season of rice is planted after the "51" Labor Day (April of the lunar calendar); If two crops are planted, the seedlings should be planted before the "51" Labor Day (March of the lunar calendar), otherwise there will be seasonal problems in late rice.

2. In terms of preparation. Prepare sufficient base fertilizer, prepare chemical fertilizer, choose good seeds and raise seedlings. There are also agricultural machinery, farm tools, etc.

3. In terms of labor. In the 21st century, China's rural areas are basically dominated by left-behind women. There is a poem "Spring Ploughing" (Zuohe Water) clouds:

The technical problems are difficult to describe.

This problem is very complicated, depending on what crops you plant, some crops can be sown directly into the ground, and some need to sprout seedlings first.

At the beginning of spring, people plough the raw land that has passed the winter to ripen the ground for spring sowing; It's called spring ploughing.

Spring. Left river water).

The east wind brings rain and the west wind, and the earth is sunny and warm.

All things are awake and the mountains and rivers are awake, and the farmers are seeking farming at the beginning of the year.

The spring ploughing time in each region needs to be determined according to the actual temperature, and it will be postponed from Jiangnan (early March) to the north to May. The further north you go, the later the spring ploughing season gets. And the specific time of year is also affected by the climate at that time.

It is usually between early March and April.

2. Northeast China.

Spring ploughing is generally carried out in late April and early May.

3. Southern region.

For example, the temperature in the south of the Yangtze River rises quickly, and spring ploughing is mostly started in early March every year, and spring ploughing only starts around late February.

4. Northeast China: The general time for spring plowing in Northeast China should be carried out at the end of April and early May.

Things to pay attention to in spring ploughing:

1. Seed preparation.

It is recommended to buy the seeds needed for your own farmland in advance.

2. Agricultural machinery purchase and potential safety hazards.

Investigation. According to their own actual situation, whether they need to buy agricultural machinery, such as rice transplanters. In addition, it is necessary to investigate potential safety hazards on existing agricultural machinery to ensure their own safety and spring plowing quality.

The content of spring ploughing production should include power, tillage, plant protection, sowing and harvesting. Stubble, deep application of chemical fertilizer, no-tillage sowing, mechanical efficient plant protection and other agricultural mechanization operations. Spring ploughing preparation work, overhaul, maintenance of agricultural mechanization equipment, timely use of spring ploughing production.

Cultivation and preparation operations, plant protection and weeding operations, sowing, etc. The reason why spring plowing is important is that its progress directly affects grain production throughout the year.

The importance of spring ploughing productionAs the saying goes, "Spring ploughing is an inch deep, and you can top up the dung." Spring ploughing is unwilling to be busy, and the face is hungry and yellow after autumn", which is enough to show the importance of spring ploughing. Agriculture is the source of human food and clothing, the foundation of survival, is the primary condition for all production, China has always been a big agricultural country, after the Spring Festival, the annual spring ploughing preparation has also entered a critical period.

It is of great significance for all localities to pay close attention to agricultural time and consolidate the foundation for a bumper grain and agricultural harvest throughout the year to stabilize the basic situation of agriculture and better play the role of "ballast stone".

<> spring ploughing refers to agricultural production activities during the period from the first day of the first lunar month to the fifteenth day of March, also known as "spring ploughing and preparation". During this time, the farmers have to carry out various preparations for the fields, including pruning weeds, clearing the fields, measuring the fields, etc. Specifically, the weeds in the field should be cut clean first; The field is then divided into blocks of a certain size with a plow; Then use a hoe and a coulter to reclaim the large pieces of soil into small squares; The size and shape of the field were then measured with cement. Finally, according to the measured figures, the time and amount of fertilization, pesticide application and nitrogen application are planned.

Spring ploughing is a very important part of traditional Chinese customs, which represents people's efforts to grow and develop crops.

Spring plowing means preparing for the spring of ploughing, including repairing farm tools, digging trenches, accumulating manure, etc.

In rural areas, due to the severe cold weather, the plough is tried to produce and cultivate, and most of them take the yoke into the cattle pen, and put the yoke on the neck of the ox, indicating that the ploughing ox pulls the yoke to plough the field, indicating that the spring is coming, and the new year begins to sow grains.

It really means sowing seeds and bearing fruit in autumn.

I feel that these are two words, so their meaning can be explained separately:

Before planting seeds in the spring, plough the land. After the beginning of spring, spring ploughing is about to begin, and the custom of trial ploughing has been inherited in some parts of China, but due to the different environmental and natural conditions in various places, the way and time of implying the traditional customs of spring ploughing production are also different.

Preparation for farming is the preparation for farming, including repairing farm tools, digging trenches, accumulating manure, etc.
