The booting stage is a key period for gaining the multiple kernel weight of wheat. In this stage, sufficient water and fertilizer supply should be provided to ensure flower growth and accumulate more nutrients, which has a good effect on preventing premature leaf senescence and improving the filling strength. Field management is mainly to maintain roots and protect leaves, extend the green time of the upper leaves, prevent premature aging or greed, keep flowers and increase grains, promote filling, and strive for full grain weight. Management should pay attention to the following points:
1. Water in time. Wheat needs a lot of water in the late growth period. This period is in the dry season, with less rainfall and more dry and hot winds. In order to ensure the normal and firm filling of wheat, the areas with conditions after heading should be watered with earing, popping, and grouting to meet the water requirement of wheat.
2. Prevent lodging. First of all, it is necessary to combine reasonable selection of anti-lodging varieties for close planting, deep ploughing and improve the quality of site preparation, promote root development before winter and greening, and adjust the group structure. Especially in the period of getting up and jointing, it is necessary to accurately judge the seedling condition, and rationally use fertilizer and water and chemical regulation. In addition, during the grouting period, pay close attention to the weather to prevent lodging caused by watering in windy days.
3. Top root fertilizer. After the flowering of wheat, the initial spraying of phosphorus fertilizer twice, the 1000-grain weight can increase 2 to 3 grams, an increase of about 10%, because the late spraying of phosphorus is helpful to increase the effective phosphorus and sugar content in wheat stems and leaves, can promote the filling, make the 1000-grain weight Increase, the maturity period advances. If the wheat leaves are yellow-green after flowering, there will be signs of premature aging, which can be combined with spraying phosphorus and spraying urea at a concentration of 1% to 2% (avoid excessive concentration).
4. Remove weeds in wheat fields in time. It is not advisable to carry out chemical weeding after the wheat is jointed. It is necessary to seize the time and manually remove it to prevent subsequent troubles caused by seeding.
