How to manage water after wheat sowing?

A short article the day before yesterday introduced several agricultural proverbs about how to fertilize wheat. Today, let's talk about water management of wheat, which is also a familiar and accepted agricultural proverb. I hope you like it.

First sentence

The environmental conditions should be suitable, and the light and warm soil should be rich in water.

If wheat wants to obtain high yield, it must be combined with environmental conditions in addition to variety reasons. This environmental condition includes light, temperature, soil, nutrition and water. Only when each growth stage meets the growth conditions of wheat can there be a good yield.

Wheat is a high water-consuming crop, and its growth can not be separated from the moisture of boiling water. Fertilizer and water can produce high yield, and drought and water shortage will reduce production. The soil is full of water and the seedlings are strong, otherwise it is difficult or difficult to be unearthed. Too much water affects the deep roots, which is not conducive to cultivating strong seedlings. Too little water is sad for winter and affects the greening in spring. Excessive humidity in spring is not conducive to the recovery of ground temperature, but also affects greening.

Do you think it is difficult? Headache.

The second sentence

During the Spring Festival, clear ditches and drain waterlogging, and apply appropriate amount of nitrogen fertilizer to quickly raise seedlings.

The Spring Festival is also a solar term in beginning of spring. The temperature will gradually rise, and the wheat will begin to elongate and enter the jointing stage. What should we do at this time?

We should take a break from the happy and busy atmosphere of the New Year, dredge the ditches around the wheat field, lower the groundwater level, and make the roots of wheat get rid of cold water soaking to promote its normal growth.

Because wheat is a dry crop, it doesn't need much water to soak its roots, so it is an important management measure to clean up the silt in time before the rainy season comes.

Secondly, as the temperature rises in spring, wheat begins to jointing, so it is necessary to apply some nitrogen fertilizer to the seedlings.

Happy Tao Tao around the Spring Festival, do you want to go to the wheat field to clear the ditch? Thinking.

Third sentence

Deep furrows have been dug in the wheat field, so don't worry about the rain.

Because before and after the Spring Festival, you may be a little reluctant to clear ditches and dig ditches. How about we do it in advance and do it after the broadcast?

Growing wheat is not strict with water and soil, so it really can't be irrigated. Wheat is a kind of crop with strong adaptability and relatively drought tolerance, so we basically choose plots with higher terrain and poor water resources for sowing, and leave those plots with better water resources for planting crops with higher economic benefits.

However, wheat is very afraid in the rainy season. They are afraid of waterlogging. They are afraid that the wheat roots will be soaked in water for a few days in the middle and late stage, and then they will rot due to lack of oxygen.

Therefore, before and after wheat sowing, you should ditch, and the ditches are connected, so that when the rain stops and the ground gets cold, you don't have to worry and do whatever you want.

The wheat fields should be connected, can you do it? I want to drop.

Fourth sentence

Wheat is afraid of rainy nights in Qingming, and the yield is low in Qingming rainy days.

Around Tomb-Sweeping Day, it was the time for wheat heading, flowering and pollination in some areas. At this time, how much wheat wants sunshine, suitable temperature, breezy south wind, deep and cold soil ditch at the foot, so that they can head and blossom contentedly, and the yield is of course ideal.

However, the weather is unpredictable. If it rains continuously during Qingming period, it means that cold air is coming! There is a lot of rain and low temperature, and wheat is very uncomfortable. Because it does not meet their needs, it inhibits the flowering and pollination of wheat, and the root of wheat contains too much water, which is not conducive to rooting and anti-aging. Therefore, the continuous rainfall around Tomb-Sweeping Day is very unfavorable to the growth of wheat, which will lead to yield reduction.

It's going to rain, can you spray chemical fertilizer to resist freezing injury? You can take this.

Fifth sentence

Foot wheat is afraid of inch water, inch wheat is not afraid of foot water.

It's a little roundabout. In other words, wheat seedling stage is not sensitive to water, and short-term water content in wheat field has little effect on wheat growth. However, when the wheat seedlings grow to the height of feet, the wheat enters the reproductive growth stage, and the growth vitality of the roots is weakening. Management should focus on raising roots, and never soak them for a long time to avoid rotting roots.

However, it is not a big problem for wheat to have more water at seedling stage, because their roots grow vigorously and metabolize quickly at this time, but they are not all right. They should also be soaked as little as possible, and the open water in the field should be removed in time to avoid soaking for too long and affecting their growth.

The moisture in the wheat field should be suitable. Did you do it? A little low.

Ok, let's say these five agricultural proverbs. Finally, an agricultural proverb is used to make the conclusion of this paper, that is, "wheat is naturally cool, and fertilizer and water are suitable for high yield;" Wheat is very cold-resistant, not afraid of snow and frost. " I added a sentence myself, "Although wheat is hard, it is suitable for high-yield environment". Haha ~, can this sentence be passed down through the ages as an "agricultural proverb"?
