How to manage soybeans in bad weather? These six points need to be mastered!

This year, the drought and flood disasters in China are more serious, and there are more extreme weather. The drought phenomenon in the south is more obvious, which is very unfavorable to the growth of soybean.

Soybean is the main cash crop in China, and it is cultivated in most areas. Now is the critical period of soybean growth. Due to the influence of weather, it has a great influence on soybean yield and quality.

So at this time, how to manage soybeans to ensure yield?

1, check and clean the three ditches, and eliminate the accumulated water in the field.

It is necessary to coordinate the three ditches: the side ditch, the surrounding ditch and the waist ditch, remove the soil in the ditch, ensure the smooth flow of the three ditches, improve the drainage efficiency and prevent the recurrence of waterlogging disasters.

In soybean field, the accumulated water in the field should be eliminated in time to reduce the soil water capacity in the field.

It is necessary to quickly organize elite troops to eliminate stagnant water in the fields, dredge rivers, open large and small drainage valves, and clean up all kinds of hidden dangers of floods. Important waterways should be specially managed by the personnel on duty. At the end of the rainstorm, the valve should be closed in time to maintain a certain water level to ensure the later farmland water and other water use.

2, timely check the seedlings, thinning, transplanting or replanting.

According to the types and varieties of local crops, ensure sufficient seedling density, and according to the current seedling situation, timely check, interval and fix seedlings to cultivate strong seedlings; Transplanting without seedlings and ridging in time, transplanting or replanting in rainy days to ensure that there is no shortage of seedlings in a large area.

3. Weed in time to prevent grass shortage.

Continuous rainy weather leads to overgrown weeds in the field. It is necessary to seize the gap without rain and choose the corresponding herbicide for chemical weeding according to the crop type to prevent grass shortage after rain.

It is necessary to use mechanical and chemical weeding techniques to carefully clean up the weeds around various crops, because these weeds are parasitic places of many diseases and insect pests, especially in recent years, a large number of dry land insects, such as salamanders, powder cigarettes and so on. I like to breed in the weeds near the field very much.

Make good use of weed stem and leaf treatment agent, and use the method of mixing gaicaoneng and fomesafen to control most monocotyledonous weeds in the field. When spraying, strictly follow the instructions and control the dosage.

4. Appropriate topdressing

Soil nutrients are easily lost after waterlogging, and timely and appropriate topdressing of available nitrogen fertilizer has a positive effect on restoring crop growth.

After the open water in the field is removed, about 5 kg of urea is applied per mu.

For local plots of stiff seedlings, intertillage management or spraying foliar fertilizer and regulator can promote the recovery of stiff seedlings.

5, timely prevention and control of various pests and diseases.

After the flood disaster, the water accumulated in the field, the soil moisture content is high, the air humidity is high, and the resistance of crops after waterlogging at seedling stage is weak, which is easy to cause root diseases. According to the specific situation, fungicides such as carbendazim and azoxystrobin can be used for spray control.

Generally speaking, most pesticides and fungicides have good control effects when it doesn't rain for five hours after use. You can refer to the comparison table that pesticides can be mixed, and pesticides and fungicides can be used together to reduce labor and mechanical costs.

6. It is suggested to replant short-season disaster relief crops such as mung beans for large-area plots with missing and dead seedlings.

For soybean fields lacking seedlings in a large area, crops with short growth periods such as mung beans can be appropriately replanted. Generally, the whole growth period of mung beans is 65-75 days, and they can mature normally.

Generally, the sowing amount per mu is 2-3 kg, the row spacing is 30 cm, the plant spacing is 13 cm, and 2-3 seeds are sown in holes.

The above are the key points of soybean field management in bad weather. Soybean is greatly affected by the weather, which is easy to affect the growth and even reduce the yield and quality.

Therefore, farmers should pay attention to the above points when encountering adverse weather.
