What are the methods for applying fertilizer based on seedling condition during the wheat green-up stage?
Spring has come, the earth's warmth rises, wheat awakens from its winter dormancy, and the green in the wheat fields increases. At this time, many farmer friends ask: Does my wheat need fertilizer? What kind of fertilizer is good? How much fertilizer is appropriate? And my answer is: apply fertilizer based on seedling condition. From

Occurrence of Spring Frost Damage in Wheat and Remedial Measures
Every year in February and March of spring, cold air frequently breaks out and moves southward in the north, with a large temperature drop during the process, and wheat that has jointed too early often suffers frost damage. At this time, for seedlings growing too vigorously, the method of pressing should be adopted to inhibit growth; for weak seedlings, reasonable topdressing should be applied to promote weak ones into strong ones

Applying winter manure to wheat requires attention to timing and method
During the overwintering period of wheat, adding winter manure can not only supplement the deficiencies of base fertilizer and seedling fertilizer, but also maintain and stabilize the soil temperature around the wheat roots. Through the slow decomposition of fertilizer in winter and absorption by the roots, it lays the foundation for vigorous growth in spring. Winter manure should mainly consist of organic matter-rich, warm-natured

What to do when wheat seedlings are weak and sparse? Apply fertilizer in time to promote tillering
After wheat begins tillering, the number of tillers increases continuously with the growth and development of the plant, and the total number of stems and tillers reaches its maximum around jointing. After that, the later-emerging tillers die off one after another due to insufficient nutrients and other reasons, and the number of stems and tillers becomes basically stable only after heading. Generally, after tillers emerge

Key Technical Points for Pest and Disease Control During the Autumn Sowing Period of Wheat
The autumn sowing period is the foundation and key to doing a good job of wheat pest and disease control. We hope farmers will seize this favorable opportunity of autumn sowing, adopt effective measures, and carry out pest and disease control work well for soil-dwelling pests, wheat powdery mildew, and other problems, striving to eliminate wheat pests, diseases, and weeds in the bud stage.

Four protections to do well in spring field management of wheat
To ensure high and stable wheat yields, after the beginning of spring, four protections should be emphasized in wheat management. First, prevent waterlogging damage. After the beginning of spring there is generally more rain, and if drainage is poor and soil moisture is too high, waterlogging damage is very likely to occur. Ditches should be cleared and drainage carried out in time, and plant ash should be spread between the rows to loosen

To manage spring care of late-sown wheat well, it should be carried out according to its characteristics.
Every year there are always some wheat fields sown relatively late. The characteristics of late-sown wheat: First, the tillering period is short. Because sowing is late and emergence is late, there is no tillering period before winter, and the spring tillering period is generally less than 20 days, so the number of tillers per plant is small, and the tillering roots are also few, which is the main reason for slow growth in spring.

Key Technical Points for Pest and Disease Control During the Wheat Sowing Period
Grasping pest and disease control from the autumn sowing period to the seedling stage of wheat is an important technical component for ensuring full and strong seedlings. The sowing and seedling stages of wheat are also critical periods for the control of many pests, diseases, and weeds. If control is not timely, it often results in missing seedlings and broken rows, or weak and diseased seedlings. In response to the pest

For high wheat yields, spraying foliar fertilizer is key
After wheat flowering, it enters the critical period of yield formation. Spraying foliar fertilizer from flowering to the grain-filling stage can effectively increase yield and quality. I. Spraying methods 1. Spray multidimensional potassium dihydrogen phosphate. Use 100 grams of 99.5% multidimensional potassium dihydrogen phosphate per mu, mix with 30 kg of water and spray evenly, once every week, spraying 2 to 3 times in succession. This can increase grain number, increase grain weight, promote grain filling, improve wheat's disease resistance and lodging resistance, prevent late-stage dry hot winds, and promote early maturity.

Spring field management for winter wheat: remember these eight key points
Spring is the critical period that determines the number of spikes per mu, the number of grains per spike and grain weight in wheat. Strengthening spring field management according to seedling conditions is the key to achieving high wheat yields. In terms of management, the eight key points of pressing, raking, clearing, topdressing, watering, controlling, preventing and protecting should be implemented as priorities. Pressing: namely early
