January wheat field management

Answer 1

If it was winter wheat, it was winter in January. Field management should pay attention to the following aspects:

** 1. Suppression **
1. ** Suppress **
- For hanging root seedlings and loose soil plots and dry wheat fields, if the soil melts in early spring, it can be suppressed. The suppression could crush the soil, reduce the water vapor, promote the close contact between the soil and the roots, and increase the temperature, preserve the moisture, resist the drought, and control the prosperity. However, the suppression should grasp the principle of "pressing dry but not wet, pressing soft but not hard, pressing light but not heavy", that is, the land with suitable or insufficient soil moisture should be pressed as soon as possible, and the wet land should not be pressed; the land with loose soil should be pressed, and the land that has not been thawed should not be pressed; the late sowing wheat should be pressed lightly but not heavily to avoid mechanical damage.
2. ** Hoe **
- After the suppression, it should be combined with hoeing to make the pine on the soil layer bear fruit. This way, it could increase the temperature and preserve the moisture, while eliminating the overwinter weeds.

** 2. Pest Control **
1. ** Weed Control **
- If winter wheat weed control is not carried out in November, the weather in December and January may be cold (according to the climate characteristics of the winter wheat growing area), and it may not be suitable to spray the weed killer. Because it was relatively ideal to spray the weeding agent in the wheat field before December 10, the low temperature in January may affect the weeding effect and may cause harm to the wheat.
2. ** Pest prevention **
- Pay attention to the possible occurrence of individual pests and diseases in spring, and monitor pests and diseases in advance. Although the temperature in January was low and some pests and diseases were lurking, preparations for pest control in spring should be made, such as planning the chemicals and equipment for pest control in advance.

** 3. Miao Qing classification management **
1. ** Weak seedling management **
- If there are weak seedlings, the goal should be to "promote the weak and control the flourishing, promote the roots and increase the tiller, cultivate strong seedlings, and protect the tiller into ears". However, the temperature in January was relatively low, so they might not carry out too much fertilizer and water operations to promote the growth of weak seedlings. They should do more soil management such as suppression and hoeing, and wait until the temperature was suitable before carrying out fertilizer and water regulation operations.
2. ** Prosperous Miao Management **
- For wheat fields that are growing too vigorously, they can be suppressed before and after the starting period (January may not be the starting period yet, so continuous observation is needed) to suppress the growth of the aboveground parts and control the prosperity.
