Rainwater has a great impact on the growth of crops. It is now in summer, the weather is changing, some places are in a state of drought, and some places deal with disasters. In the case of Hunan, there have been heavy rains in many areas recently. It is timely rain for dry crops, but if it is too much, it is not good. The farmland is prone to guilt, water, etc. If it is short-term water accumulation If you don’t retreat for a while, you can’t sit back and watch. The following small series will introduce the farmland water management measures.

1. Drainage

The first thing that everyone thinks is that there is water in the farmland to drain first. This is correct and the first thing to do first. If it is a high-altitude farmland, you can ditch the field and let the water flow out as quickly as possible (such as roadside Small ditch, or other places), if the low-lying farmland, the water in other places flows into the farmland, the drainage can not be discharged, can only wait for the natural dry (for this individual situation, no way, It can only be planted. If it is a flood, no matter the terrain, it will not work. Of course, this special situation is rare. If it is really encountered, then waiting for the reconstruction after the disaster, there will be relevant departments to guide everyone, but they do not want to appear. This article is still about the case of ordinary rainfall with water.

The weather in summer is changing very fast. Sometimes it is rainstorm yesterday. The next day is more than 30 degrees of high temperature. So when the water in the farmland fades, after a few days, the land can stand and the soil skin is cracked. In the case of the situation, the purpose is to ensure the normal breathing of the roots of the crops and promote their normal growth, because after the rain, the soil will dry up after the sun is shining, and the root growth is hindered due to the evaporation of soil moisture too fast. Crops are naturally inhibited. After the slashing, it can maintain a part of the water loss, which provides favorable conditions for crop growth.

3, top dressing

Why do you need topdressing? When crops are planted, they usually apply base fertilizer to provide nutrients for the subsequent growth of crops. When they encounter guilt, when there is water in the field, the nutrients in the farmland will be lost with water (or even most of them). Therefore, after the past, the farmland should be topdressed in time. In addition to NPK, some trace elements can also be applied. According to different crops, choose different proportions, but remember not to be too much. Some friends I think that the more topdressing at this time, the better, in fact, it is not, to avoid the symptoms of greedy crops.

4. Pest control

When the farmland appears to be infested, the crops in the farmland will be affected more or less, and the resistance will decline. In addition, the humid weather will increase the occurrence of pests and diseases. Therefore, the pests and diseases will increase in a timely manner. For prevention and control, what kind of medicine should be used depends on different crops and different pests and diseases. It is recommended that friends who are not sure can take dangerous crops and go to the local farmer's store for detailed consultation. They will introduce you to the medicine.

In the case of farmland squatting, we as farmers, we certainly do not want to let it happen, but sometimes we can't control this situation, we can only do remediation and avoid causing greater losses. I hope that the farmland water treatment method shared by Xiaobian can help the farmers!
