Late stage Management of High quality Wheat
After the wheat turned green, the high temperature and drought persisted, and the stages of getting up, jointing and raising the flag were all 5 min 7 days earlier than usual. At present, the seedling condition of wheat is close to that of the whole year, but the growth of the plots is not balanced. Therefore, it is suggested to strengthen the late management of high quality wheat: 1. Carry out fertilizer and water management of booting and heading as soon as possible: this fertilizer and water can not only promote floret development, increase floret seed setting rate and increase grain number per spike, but also promote nitrogen absorption and transformation in the later stage of wheat, which is a compulsory index for wheat yield, protein content and wet gluten content.
