The drought will also aggravate the suggestion of experts to water wheat as soon as possible.

There is still little rain in our province in the second half of this month, and relevant experts suggest that wheat fields be irrigated as soon as possible in arid areas to minimize the reduction of summer grain production. In the first ten days of May, the temperature in most parts of our province was high, and the precipitation continued to be low. Drought disasters of varying degrees occurred in Linzhou, Puyang, Lushi, Luanchuan, Yichuan, Xuchang, Xiangcheng, Shangqiu and other places, and the soil moisture was lost rapidly. it has certain adverse effects on winter grain filling, spring sowing crop sowing and seedling growth. The meteorological department predicts that by May 18, with the exception of suitable soil moisture in some areas of northern, eastern and southern Henan, there will be a relatively serious drought in most other areas, and the soil relative humidity will be less than 45%. At present, wheat in our province has entered the milk stage one after another, and the appropriate soil moisture is beneficial to the growth of wheat at this stage. Arid areas should be irrigated in time, but the amount of irrigation should not be too large to prevent wheat lodging and affect the yield. According to the current crop growth status, soil moisture and future weather forecasts, meteorological experts suggest that irrigation should be made in time in areas with moderate or above drought to prolong the filling time of wheat. All localities should also do a good job in the prevention and control of dry and hot wind to provide good conditions for the formation of wheat grain weight, and where possible, growth regulators such as potassium dihydrogen phosphate or "BN" can be used to spray wheat leaves to prevent and reduce the harm caused by dry and hot wind or high temperature weather.
