If it doesn t rain when farmers farm the land, can the well water be harvested in the face of drough

It is common for well water to irrigate rice. The cold rice farming area in the eastern part of Heilongjiang was once the largest well-irrigated rice growing area in the country, and the consumption of groundwater was extremely alarming. With the improvement of river irrigation engineering facilities in recent years, most of the well water irrigated rice farming areas have also realized river water irrigation, which has a positive effect on the yield and quality of rice and the reduction of groundwater consumption in Heilongjiang.

Therefore, for rice planting, if the timely irrigation of well water and the sufficiency of water can be ensured, it will not have any direct impact on the yield of rice.

However, dryland crops are different. First of all, China's farmland infrastructure construction is relatively backward, and there is no such perfect irrigation equipment. with developed countries in Europe and the United States.

In comparison, China's farmland irrigation equipment is much more backward, and it may only be in the Xinjiang Production and Construction Corps.

And Heilongjiang Agricultural Reclamation can see the kind of large-scale self-propelled irrigation equipment, in other areas unless it is the first or the enterprise to invest in the purchase of such expensive irrigation equipment. Otherwise, with the financial resources of most farmers in our country, it is impossible to buy expensive equipment.

Secondly, the groundwater situation in China is quite different. The overall topography of China is about high in the west and low in the east, and the distribution of groundwater is also quite different. Relatively speaking, the Northeast region.

The groundwater is more abundant than that in the western region, and the difficulty of pumping well water is relatively small. Therefore, some rural areas in Northeast China can see some wells for pumping groundwater, and the utilization rate is relatively large. But it's not the same elsewhere, and whether there is enough groundwater is still a question.

Another point is that the timing of the drought is different. If it is a drought before and after planting, it is difficult to rely on well water irrigation to alleviate it. As the saying goes, the more well water is watered, the drier it gets.

It may not be very obvious in the later stage, but the use of well water to resist drought before and after the sowing period will not be effective. If it is a drought in the middle of growth, as long as the irrigation facilities are in place and the irrigation water source is sufficient, the impact of drought can be alleviated to a certain extent. If it is what farmers commonly call "neck drought", it is very difficult to simply rely on well water to fight drought.

Finally, there is the input-output ratio. Groundwater extraction requires the consumption of electricity, diesel and other materials. The installation of irrigation equipment also requires a relatively large investment, and the maintenance and normal use of the equipment also require funds.

If irrigation is carried out, it is also necessary to consider whether the corresponding output and income ratio can be obtained.

Farming can be harvested without rain. However, it is necessary to increase manpower and material resources, and there are wells with well water, and rivers with river water. This is not the condition in every place, one is that there are few wells and many lands, and it is often said that far water cannot quench the thirst of the near.

There are thousands of kilometers of plastic pipes to be used far away, and it can be tiring to erect pipes to water the ground. Well, only the lads can do it. That's why it's not raining.

There are prerequisites for a good harvest. Therefore, people will win the day, it is just a slogan, it is not so easy to implement, or God is good when it rains, the rain is even, and it can rain no matter the high slope and the bottom depression. It is also labor-saving and cost-saving, and the land crops like it, the well water is hard and cold water is not good for harvest, and the rainwater contains oxygen and high nitrogen, which is soft water, and the crops are easy to absorb.

If you want a good harvest, it depends on the sky.

As long as you water it regularly, you can have a good harvest. Nowadays, many farmers rely on their own strength to grow, not necessarily by raining for watering.

No, because it is not enough to rely on well water to fight drought, and in the end, many plants will not be able to be watered.

Local rural people often say: "Dog days drought, timely watering", which means that the dog days are hot, and it is a critical period for crop growth, such as corn, soybeans, cotton and other crops in the Huanghuai region, if there is no rain to moisten, this dog days, will be tormented. Rural people also say that in the dog days, "there is a small drought in three days, a big drought in ten days, there is no rain, there will be smoke in the ground", "there is no drought in the dog days, and the crops will be bumper", etc., these proverbs that circulate in the countryside are an accurate summary of a solar term.

However, in the rural fields, the corn fields are another way, a lot of corn is obviously dehydrated under the exposure of the sun, the leaves are curled up one by one, and the leaves are more serious, the leaves begin to dry up from the tip of the leaves, and the corn is originally lush and thriving, and the growth is about to enter the most critical ear stage.

But the key is that the poor corn, and other cash crops, is in stark contrast, we see in a field of Chinese medicinal materials, just watered on both sides of the Chinese medicinal materials, planted corn, those "wet" corn, the growth is very gratifying, and the distant thirsty corn, in sharp contrast.

In the state of corn, if it drags on, it will inevitably affect the yield, obviously there are wells for irrigation in the field, why don't farmers actively irrigate? According to Uncle Liu in the village, my family's corn belongs to no one to irrigate, the children have gone out to work, and the family has planted more than ten acres of corn.

In addition, most of the corn has grown to a depth of one person now, irrigation? If you ask us rural people to irrigate, with our existing irrigation measures, we can't meet the demand for corn irrigation. Especially for the young people in the village, they can earn one or two hundred yuan a day by working or going to work in the city, and if they come back to fight the drought and delay one day, they will lose one day's income, which is somewhat more than worth the loss.

Nowadays, rural people are less and less dependent on land, and it is not surprising that agricultural products are not worth the amount of money earned by working in the sky. In fact, it's not that we don't want to irrigate, but everyone is looking forward to it, hoping that the sky can rain as soon as possible, and give the corn in the field a happy moisturization. In hot weather, it's too hot to sit, who wants to take the initiative to irrigate?

I think that if you use well water to fight drought, you can also get a certain harvest, after all, the well water is open up to the groundwater under the mountain, and can effectively ensure that the crops receive water in time, but if you use well water for a long time, it will also have a very serious impact on them.

The effect is limited, and sometimes you need to be very industrious, and you must water the ground with well water in time, so as to avoid soil drought and have a good harvest.

It must be possible, mainly because it hasn't rained all the time, so this is the only way to save it.

This can be well relieved. Irrigation with well water can prevent soil drought, can promote the growth of plants, and can be treated for a period of time.

<>, especially in some areas where drought often occurs, if you want to carry out large-scale planting, you must store water in advance, in case you save energy to give crops sufficient water during drought, then we can build water storage tanks to store water, after my understanding is about 4 kinds of water storage tanks, <>

The impact of drought on crops.

The impact of prolonged drought on crops is multifaceted, and the consequences of different drought periods are also different, such as:

1. Post-sowing impact: When the crop is just sown, it is the time when germination water is needed, if there is no water, the seed will not break the shell, which will affect its survival rate.

2. The impact of seedling stage:

Drought at the seedling stage will inhibit the growth rate of plants, delay the development period, promote early maturity of crops, and lead to the shortening of the development period.

3. Effect of plant growth height: drought will significantly inhibit plant growth height.

4. The impact of crop leaves: drought will cause the leaves of crops to shrink and even die.

5. Yield impact: drought can directly lead to a large reduction in crop yield or even no harvest.

How can we respond to the drought? Irrigation and watering generally come to mind, is there any other way? Really, none of us have any other good way to prevent drought, and this cannot be prevented in advance, unlike diseases and pests, which we can also use pesticides to prevent and control after they occur.

1. Variety: We can choose the quality with strong drought resistance for planting.

2. Irrigation and watering

If we have irrigation conditions, we can water as soon as possible, storage tanks, wells, riversides, etc., if there are no irrigation conditions, we can learn from the following.

3. Root irrigation: If we do not have other better irrigation conditions, we can carry out artificial spraying, mainly for the root spraying of crops, and can appropriately add the fertilizer required by the plant, so that the plant can not only absorb water, but also absorb the nutrients required for growth, so as to ensure the normal growth of the plant and lay a good foundation for the harvest.

Watering should be chosen in the morning or evening, is the best, these two time periods of temperature are relatively low, water evaporation is relatively slow, the plant is easy to absorb water to grow. Lay the foundation for a bumper yield in the later period.

5. Watering depth: When we water the plants in the drought period, we must not water half of the water, that is, the soil surface is wet, and the bottom is actually dry, so that the root system of the plant cannot absorb water, and it does not play the role of watering at all, and it wastes water. When watering, we should pay attention to see, if there is a small amount of water on the surface of the soil, and it will not sink down, it means that it has been watered thoroughly, but it should not be excessive!

First of all, it is necessary to choose drought-resistant excellent corn varieties, which we should have no doubt, when the weather continues not to rain, there is a certain drought, the choice of excellent drought-resistant corn varieties is indeed beneficial to the emergence of seedlings and the growth of the later stage, so when buying corn seeds, it is necessary to choose carefully, it is best to choose full grains, strong arch soil ability, and more drought-resistant corn varieties The second method is to raise seedlings first and then transplant, if the planting area is not large, this method can be used, In our local area, crops such as corn and sorghum are advanced seedlings, and then transplanted, in the case of continuous rain, seedlings can be raised first, and then transplanted, which can not only solve the problem of drought, seize the season, but also be easy to manage, in the seedling period can greatly save water, and wait until the rainy season comes to transplant in time.

A week after sowing should be irrigated using water from a well or river. Irrigate immediately after the seedlings grow, so that there are no large and small seedlings. Wait until the plant is jointed and water it again.

I think the countryside is relatively backward, and they have some facilities, but they can't pump water, and the farmers can't do it, so it's more helpless.

Because of the lack of water. Some villages do not have water supply equipment, and the water supply is difficult, and it is necessary to transfer water from a distance, and most of the time it can only rely on rain.

It is possible that the farmer will not come back from the work because the round-trip fare is too expensive. It could also be because the well is running out of water.

Dry-seeded rice saves ecological water demand and tillage water demand, but it must meet the physiological water demand of rice plants. Generally, natural precipitation is the mainstay, supplemented by irrigation. No irrigation can be done before emergence, but if the soil field water holding capacity is less than 75%, the bottom water can be watered and sown, and the later stage can be combined with spraying and fertilization, and irrigation at the appropriate time.

Irrigation period and index: In order to make dry-seeded rice have high yield, it is necessary to meet the water demand for the growth and development of rice plants at tillering stage, jointing stage, booting stage, heading stage, flowering stage and grain filling stage. In the event of a prolonged drought, when the soil moisture is less than 65% of the maximum water holding capacity (when the plant is pulled out of the soil, the base of the rice plant is shaken, and the soil falls from the root system), irrigation is required in the field.

If the water holding capacity in the field is higher than 80%, the soil moisture can meet the needs of rice plant growth, and irrigation can be required.

The irrigation method should be irrigated in the morning, and the water flow should not be too violent. Because the temperature difference between the body temperature and the water temperature of the rice plant in the morning is small, the viscosity of the protoplasm of the root of the rice plant is avoided and the permeability of the cells is reduced. Water slowly infiltrates the soil, so that the soil water content reaches a saturated state, which is conducive to the absorption of water by the roots.

Especially for the first time, don't irrigate too violently to prevent the xerophytic roots from turning into aquatic roots, and the leaf color will turn yellow and stagnate for a long time. The principle of irrigation is that the first water is early, the second water is tight, and the third water is full.
