What does the folk proverb "it doesn't rain in the long summer, and the plow hangs high" mean?

It doesn't rain in the long summer, and the plow hangs high. This agricultural proverb refers to the arrival of the long summer solar term, which is a favorable weather for rain. During the long summer, the rainfall is relatively insufficient in both the farmland in the south and the farmland in the north. Especially in the main wheat producing areas in the north, at this moment, wheat is in the flowering and filling period and needs abundant precipitation. If there is no precipitation at this time, the dry weather will shrivel the wheat seeds, resulting in reduced production.

According to the description of agricultural proverbs, there is no precipitation in long summer, and the dry weather will last until June. Such a long drought will have a great impact on agriculture, which will not only lead to a reduction in summer grain production, but also bring great trouble to autumn grain sowing. Because it doesn't rain for a long time, the dry soil has no moisture suitable for sowing, and it's useless to plow and rake, and it's useless to hang it high inside. This also explains why a long summer without rain will bring about a continuous drought.
