Nowadays, the season of wheat rejuvenation is reached. According to the fertilizer characteristics of wheat, the three fertilizers in the spring management of wheat can be scientifically and rationally applied, which can ensure the high quality and high yield of wheat without causing waste of fertilizer.
For the first time: apply the jointing and booting fertilizer. The traditional method of watering and fertilizing when the wheat is greened is changed. For the first and second types of wheat fields, the control is mainly carried out. Under the condition that the soil moisture maintains the normal growth of wheat, the fertilization time is postponed until the end of March, that is, the wheat jointing period. In the later stage of jointing, 15 kg of urea or 40 kg of ammonium bicarbonate were applied in combination with watering. This can effectively control the excessive proliferation of wheat inefficient tillering and the length of the first internode, reduce the plant height, and enhance the ability of wheat to resist lodging in the later stage. For wheat with weak growth or late sowing, it should be promoted mainly. When the daily average temperature is stable above 5 °C, fertilize water as soon as possible, apply 20 kg of urea per mu or 50 kg of ammonium bicarbonate to promote wheat growth and development.
The second time: the pursuit of picking the flag. The flag-picking period is the critical period of wheat water demand. At this time, 5-6 kg of urea can be applied in combination with watering, which can effectively reduce the degradation of florets, increase the number of grains per ear, and increase the deep water storage capacity of the soil for later absorption and utilization.
The fourth time: increased spray grouting foliar fertilizer. In the early stage of wheat grain filling combined with wheat ear mites, spraying 1-2% urea solution 30 kg, re-spraying once every 7 days, can effectively increase wheat grain protein content and wet gluten content, and at the same time enhance wheat resistance to dry hot wind Ability to delay leaf senescence, increase the 1000-grain weight of wheat, and achieve the purpose of increasing production.
