Which month is the best to go to Wuyuan to see rape blossoms?

Affected by the low temperature in the south at the beginning of this year, the rape blossoms in Wuyuan opened late this year. Since mid-March, rape blossoms have been opened in scenic spots such as Rainbow Bridge and Likeng, and the flowering period will end at the end of April. The flowering period of rape in Wuyuan is generally in March and April every year, but it is early and late, and sometimes there is a difference of half a month in different years. There are many factors affecting rape flowering, mainly weather conditions, rape varieties and topography. The first is the weather. If the temperature rises quickly in spring, rape will definitely blossom early. From previous years, it began to blossom early at the end of February, flourished in mid-March, and withered at the end of March and early April (before Tomb-Sweeping Day). The flowering period is generally more than 20 days. If the temperature does not rise in spring and remains low for a long time, rape may blossom in mid-March, blossom in late March and early April, and wither around 10 in April. Therefore, weather conditions are the biggest factor affecting flowering. When it snows, the growth of rape flowers almost stops, and the weather is sunny, and rape grows very vigorously. It will be different in a few days. Secondly, different rape varieties have different flowering times. Generally speaking, Wuyuan local varieties bloom earlier. This variety generally has thinner stems and smaller flowers. The flowering time is generally one week in advance, and the flowering period is generally short. Commonly known as "soil rape", its flowering period is one week to ten days earlier than what we call "victory rape". The other is a high-yield and excellent hybrid variety with large plants, strong flowers, dense flowers and many seeds. Generally, the flowers bloom late, so we call it "victory rape". This kind of rape generally blooms late and has a long flowering period. Again, the terrain varies from place to place. Wuyuan has high and low terrain. In low-lying areas, rape blossoms will bloom earlier, and generally the same variety will be five days to a week in advance. For example, rape blossoms in Jiangling and Qingyuan will be later than those in Yantian. Generally speaking, the rape blossoms in Wuyuan are like this every year: some low-lying places in the local area bloom the earliest, and then the "Shengli rape blossoms" in these places (such as Yantian, Long Beach and Zhang Cun) bloom in large areas, and then the rape blossoms in Jiangling and Qingyuan. Generally, when the flowers are in full bloom, the rape flowers will wither in the strong wind and heavy rain, so it is very regrettable to see that the rape flowers disappear in a few days. Flowers bloom for about a month, but the most suitable time for viewing is about 20 days.
