Affected by the low temperature in the previous period, Ningxia has long been lagging behind. It is expected that due to the influence of cold air, from April 30 to May 2, most areas of Ningxia will have light frost and some areas will have frost. It is disadvantageous to the late growth of alfalfa. It is recommended to pre-fill the water before the cold air strikes, increase the humidity and temperature of the plantation, avoid the freezing of the flowers and leaves, and affect the fruit. As the main production area of ​​Ningxia, the country has entered the leaf-expansion period from March to April every year. However, the average monthly temperature in Ningxia in March this year was only 0.6 °C, which was 1.7 °C lower than the normal period. In April, the undulating temperature and the occasional visits from the frosty weather made the growth period of Ningxia lag. Compared with previous years, the leaf-expansion period of Ningxia carp has lags behind 7~10 days. In addition to the delay in the leaf-expansion period, the dry climate lacking precipitation in Ningxia this year has also led to an increase in the number of mites. In the past years, only the pesticides that can be controlled by pesticides in the past year have to be repeated twice to suppress.
