What is spring ploughing? What should we pay attention to in spring ploughing and fertilization?

China has been a large agricultural country since ancient times, so there are many proverbs about farming, such as "spring ploughing, summer ploughing, autumn harvest and winter collection" is one of them. Do you know what spring ploughing is? What should we pay attention to in spring ploughing and fertilization? Let's get to know it together with the editor of Tuliu.com.

What is spring ploughing?

1. Interpretation of spring ploughing

The general explanation for spring ploughing is to cultivate the land before sowing in spring. Spring ploughing usually begins after the Beginning of Spring, and the custom of trial ploughing has been inherited in some parts of our country, and there are many proverbs about spring ploughing, such as "ploughing well and raking well, only crops grow no grass" and so on. However, due to the different environment and natural conditions in different regions, the customs and methods of spring ploughing are also different.

two。 The custom of spring ploughing

Due to the differences in cultures and habits, the customs of spring ploughing are also different. For example, in the annual spring ploughing season, Huangshui Town in Chengdu holds a series of activities to beat the spring bull to add color to the spring, including the memorial archway to welcome the spring, the spring bull to make a spring, the colorful dance to whip the spring and so on.

Yanggu County, Liaocheng City, Shandong Province will hold activities such as cockfighting and sheep fighting during the spring ploughing season, so as to look forward to the favorable weather, abundant grain and prosperous six livestock in the new year.

Hakkas in Changting County, Fujian Province will conduct spring ploughing activities, usually wrestling and running in the fields, and also looking forward to a good harvest in the new year.

Second, what should we pay attention to in spring ploughing and fertilization?

Spring is the season for ploughing and sowing, but fertilizing after spring ploughing and sowing is also very important, but due to the different habits of crops and the amount of fertilizer applied, the following points should be paid attention to during spring ploughing:

1. Mixed use of ammonium bicarbonate, urea and bacterial fertilizer

Urea and ammonium bicarbonate are often used in fertilization, and bacterial fertilizer will also be applied at the beginning of spring, but here we should remind growers that ammonium bicarbonate can not be mixed with urea and bacterial fertilizer. The use of ammonium bicarbonate and urea will accelerate the volatilization loss of nitrogen in urea, while the use of bacterial fertilizer together will make the bacterial fertilizer invalid.

two。 Cannot be watered immediately after urea application

After urea is applied to fruit trees, it can not be watered immediately, because urea will be converted into amide after being applied to the soil. If it is watered immediately, it is easy to lose with the water, and it cannot be applied before heavy rain. It should be noted that after the application of urea, the way of covering soil can improve the fertilizer efficiency.

3. Alkaline fertilizer should not be mixed with alkaline fertilizer and ammonium nitrogen fertilizer.

Because the neutralization reaction is easy to occur when applied together, which will lead to the volatilization loss of ammonia and nitrogen, thus reducing the fertilizer efficiency.

4. The use of high concentration fertilizers and unripe manure should be prohibited or reduced each time.

It is common to eat manure in rural areas, but it should be noted that rotten manure must be used, otherwise it is easy to make plants burn roots or virus diseases; and excessive application of fertilizers with too high concentration will also cause root burning or death of plants.

3. Spring ploughing time in various places

Does our country have a vast territory, and the climate and temperature in different regions are also quite different, so the time of spring ploughing in each region is also different.

1. North China region

It is usually between early March and April.

two。 Northeast China

Spring ploughing takes place at the end of April and early May.

3. The southern region

If the temperature in the south of the Yangtze River picks up quickly, spring ploughing usually begins around the end of February in early March every year.

4. Northeast China

The common time of spring ploughing in Northeast China should be at the end of April and early May.

When we are carrying out spring ploughing, we should carry out spring ploughing according to the climate change at that time, and fertilization should also be determined according to the fertilizer needs of crops and land. the above is all the contents introduced by the editor of Tuliu.com, which can be used as a reference.
