Do I need to do field irrigation before ploughing?

The water used for irrigation in earthen canals is usually transported from the water source through channels. The passage is long and short, short for tens of meters, singing for tens of kilometers and hundreds of kilometers. If the channel is dirty, some water will leak down during the water transfer process and will not reach the field.

The amount of water lost along the way usually accounts for 50 -60 of the water supply, and in some places even 70 percent. It's a pity!

When farmers water their land, they often don't pay attention to saving water. Instead, they use traditional methods to irrigate the land and fill the entire field with water. This water is poured into the fields in large quantities, filling the whole world with water.

The irrigation method is called "flood irrigation" or "flood irrigation". If the land in the field is uneven and of different heights, the land will be flooded and the water consumption will be greater.

Irrigating the land in this way wastes a lot of water. Large amounts of water cannot be absorbed by crops. Sometimes, the growth of crops is affected due to the high amount of moisture.

The farmer has enough nutrition for the sake of the farmer. Fertilizers are applied to the fields, and too much water in the fields can also cause these fertilizers to be lost elsewhere with the water, so that crops do not get enough nutrients. For farmers, the high water consumption also increases the cost of agricultural production.

The first thing is to know whether this is a mechanical deep flip or a deep flip of humans and animals. If it is a mechanical deep flip, it is not afraid of not being able to flip. It is a rotary tiller that can be deepened in any field.

If deep ploughing is used, it is necessary to pay attention to the humidity in the field. If the field is too dry, people and animals will not turn, sometimes the horse water should be released, and then the field can be turned over, so that the outside can be flipped, the efficiency is very high, the disadvantage is that it is afraid of rain, if it rains, it will affect the subsequent sowing.

Yes, it is needed, it can effectively humidify the land and can speed up ploughing.

Drip irrigation should be carried out before ploughing, rather than flood irrigation of the field.

This is not necessary because if the field is flooded after ploughing, the water will be lost quickly.

Yes, but it is generally enough to sow seeds after the rain

There is no need for field irrigation before the land is ploughed, and if you fill the land with water, how can the agricultural machinery that plough the land enter the farmland, how can it turn the ground? To irrigate the land, it is necessary to use agricultural machinery to level the land after the land is ploughed, and after the land that needs to be ridged is ridged, it is necessary to look at the moisture of the land that has been turned up.

How, if the moisture of the land is very good and suitable for sowing and planting, you can sow and farm, and there is no need to water and irrigate the land!

That is to say, when sowing the land, the soil moisture is suitable for sowing and planting, and if the seeds can germinate smoothly after sowing, there is no need to irrigate the farmland. When the seeds germinate and unearthed, it is necessary to check the soil moisture every day, to observe the growth of the seedlings every day, to see if the farmland is short of water, to see if the seedlings need water, if the growth of the seedlings needs water, then the farmland should be watered and irrigated immediately, in order to ensure that the crops need water during the growth period.

If you don't need to sow the seeds immediately after ploughing the land, you don't need to irrigate the land, regardless of the moisture of the land. You irrigate early, and when you sow and plant, the soil may be dry and dry again, and you have to re-water the land, which means that you have wasted manpower and material resources, and you have done a useless job by irrigating the land once!

If you are about to sow seeds after ploughing and preparing the land, and the soil moisture is not good, the soil is dry and dry, and the seeds cannot germinate immediately after sowing the seeds, you have two options for watering and irrigating the farmland

1.Irrigate the farmland before sowing, irrigate the farmland thoroughly at one time, and then you can sow the seed, so that when you finish sowing the seed, after planting, the seed will also sprout and emerge in the first time!

2.Regardless of the extent of the drought of the land, when it is time to sow the land, immediately sow the land, after sowing, immediately water and irrigate the farmland after sowing, and also irrigate the farmland with water at one time, so that the seeds after sowing will be moistened by the water, and will sprout in the first time to be unearthed, these two methods of watering and irrigation are OK, and you can also choose according to your actual situation!

According to the planting situation, there are some plants that need to be flooded, and some dryland plants are not necessary to do so, and flooding can better retain the moisture of the soil, which is conducive to the growth of plants, and the disadvantage is that it is more water-intensive.

The mouldboard plough is the most commonly used ploughing tool. Due to the different plow body structures of various ploughshares, there are also differences in performance and usage. Generally, the plough wall of the mouldboard plough is fixed, and the soil can only be turned to the right side.

When cultivating land, the inversion method or the valgus method is often used. The former starts from the left side of the center line of the operation area, runs in a clockwise direction, ploughs from the middle to both sides, and finally leaves the ridge in the first place, leaving the furrow on both sides; The latter is ploughed from the right side of the operation area, runs in a counterclockwise direction, ploughs from the outside to the inside, and finally leaves a furrow on the **, leaving a plough ridge on both sides. Intertillage is usually performed alternately with inward and outward varus, thereby reducing the number of furrows.

When using two-way ploughing to plough the land, the shuttle tillage method is adopted to turn over the same side of the land; After ploughing, the field does not produce furrows and ridges, which is conducive to land leveling, and is usually used on slopes, paddy fields and irrigated land. Turning capacity: 135° can be turned with a universal plough; Wasteland uses a plough with a spiral wall that can be turned 180°.

In addition to the plough, there are also those that use disc ploughs or shovels to plough the ground, but the ability to turn the soil is weak.

The depth of ploughing depends on a variety of factors such as crop type, soil texture, local climate, season, etc. For example, root crops such as sugar beet and sweet potato should be deeply cultivated; Shallow root crops such as rice and millet should be relatively shallow; The clay soil should be deeply cultivated, and the sandy soil should be shallow tillage; Autumn ploughing should be deep, spring ploughing should be shallow; The fallow land should be deep, and the sowing should be shallow, etc., which must be adapted to the local and timely conditions. The Soviet Union generally advocated ploughing to a depth of 20 to 22 cm, and root crops such as potatoes were often deepened to more than 25 cm; Experiments were carried out in Western European countries for 5 to 10 years, and the general depth was 20 25 cm.

China's practice shows that increasing the depth of the old plough from 12 to 13 cm to about 20 22 cm or 25 cm of the machine-led plough often has the effect of increasing yield; Deep tillage combined with the application of organic fertilizer has a more significant effect. The period of ploughing generally varies with the local climate, ripening and crop growth period. According to different tillage seasons, China can be divided into four types: autumn tillage, winter tillage, spring tillage and futile tillage, and the suitable time to adjust soil moisture and mature soil should be selected.

Generally, ploughing as early as possible after the crop harvest is conducive to improving the quality of land preparation.
