Detailed explanation of key field management points for winter wheat in early spring

After entering March, wheat also enters the green-up and jointing stage, and this is also the peak period for weeds, diseases, and pests. At present, wheat is gradually entering the green-up and jointing stage, and from the overall growth condition, it is still quite encouraging. So how should winter wheat be managed after entering March? Let's take a look together.

1. Weed control

After entering spring, wheat enters a rapid growth period, but weeds grow even faster, so wheat fields that have not been weeded should promptly carry out weed control. Weed control generally uses chemical agents, and spring chemical weed control should pay attention to the growth and development status of wheat, mainly checking whether it has jointed. If the wheat has already jointed, in principle, herbicides should not be used. For wheat that has not yet jointed, chemical weed control should be done in one step, because in terms of time and season, there is no room for delay.

2. Prevent waterlogging damage

There are many cloudy and rainy days in spring, and rainfall is naturally relatively heavy, which easily causes waterlogging and flooding damage, so wheat fields should do a good job of clearing the three ditches. In particular, the field-edge ditches should be deepened, and ditches outside the field should be dredged, to reduce waterlogging and flooding damage as much as possible, protect roots and leaves, prevent premature aging of plants, and ensure that wheat can grow steadily.

3. Apply jointing fertilizer as a top dressing

Applying jointing fertilizer well is an important measure to ensure the ear-bearing rate and increase the number of grains per ear. For plots with a small wheat seedling population, dull leaf color, poor soil fertilizer supply capacity, or no green-up fertilizer applied as a top dressing, jointing fertilizer should be applied in early to mid-March according to the jointing condition of the wheat. For plots with a large wheat seedling population, strong leaf color, strong soil fertilizer supply capacity, or where green-up fertilizer has already been applied as a top dressing, top dressing should be appropriately delayed, and the amount of top dressing should be appropriately reduced, applying jointing fertilizer in mid-to-late March when the leaf color fades.

4. Promote weak seedlings to become strong

For yellow seedlings, weak seedlings, diseased seedlings, and herbicide-damaged seedlings, on the basis of applying an appropriate amount of quick-acting fertilizer, foliar spray plant potential activators or biostimulants. For example, seaweed foliar fertilizer, humic acid multifunctional foliar fertilizer, amino acid foliar fertilizer, brassinolide, potassium dihydrogen phosphate, etc. can be selected to supplement plant nutrition, improve stress resistance, promote young ear development, and lay a good foundation for increasing yield and improving quality.
