Wheat management method

First, adjust measures to local conditions and scientifically manage fertilizer and water. For wheat fields with normal growth and high fertility level, jointing fertilizer should be applied again in combination with watering at jointing stage; For wheat fields with moderate fertility, quick-acting chemical fertilizers can be applied with water at the beginning of the flood season; For three types of wheat seedlings with poor drought length, on the basis of weeding in early spring, topdressing twice at the turning green stage and jointing stage to promote tillering and ear formation in spring, improve the ear formation rate, promote the development and fruiting of florets and increase the number of grains per ear; For late-stubble seedlings with no basal fertilizer or less chemical fertilizer, soil moisture should be used for topdressing when the soil has just thawed, but it is not advisable to water them to turn green, so as to avoid the decrease of ground temperature and poor soil permeability, which will affect the growth of wheat plants. On the basis of careful weeding, wheat can promote fertilizer and water in the early stage of growth, and it is appropriate to apply urea 10 kg per mu. Watering should be carried out when the average ground temperature is stable at about 5℃, so as to avoid freezing injury caused by premature watering.

Second, it is necessary to practice intertillage in general. Generally, all kinds of wheat fields at all levels should be cultivated in intertillage before and after the turning green period of wheat, so as to break the board, remove weeds, increase the temperature and preserve moisture, and promote the early development and rapid growth of seedlings. Specifically, for weak seedlings, shallow hoes should be used to break the hardening, promote the weak to become strong, and prevent root damage and heavy seedlings; For the wheat fields that are likely to grow vigorously, it is necessary to dig deep appropriately to inhibit the growth of the above-ground parts and control the vigorous growth; For extensive land preparation, especially for the wheat fields that are not watered by rotary tillage, as well as the wheat fields that are flourishing, it is necessary to suppress them in time and master the principle of pressing dry without pressing wet, frozen and saline-alkali land. In addition, repression should be combined with intertillage, and it is best to press first and then hoe, so as to achieve the effect of improving soil moisture and keeping moisture and warming.

3. For dryland wheat in hilly areas without water irrigation, spring management should focus on preserving soil moisture and increasing temperature. Generally, it can be used for ploughing and topdressing after the soil in the early spring wheat field is thawed. If there are symptoms of fertilizer removal from the beginning to the jointing stage, appropriate topdressing should be combined with rainfall; For arid and fertile land with large seedlings and high soil fertility level before winter, topdressing can be done as appropriate from getting up to jointing stage. Topdressing can be done by deep furrow or ploughing to avoid the loss of fertilizer. Nitrogen and phosphorus should be applied together in plots with insufficient phosphate fertilizer at the bottom.
