In the past, spring ploughing and sowing were all in March and April of the lunar calendar, so at this time, the grain at home has been planted as seeds, and the wheat planted in winter has not been harvested at the filling stage, so from the traditional point of view, it is a green and yellow stage.
In the past, the countryside was relatively poor and the grain output was very low. Farmers have worked hard to plant the grain harvested in one year, which may last less than one year. Therefore, there is often no food after the New Year, and it is often necessary to dig wild vegetables to satisfy the hunger, in order to survive this period of green and yellow days, that is, March and April of the lunar calendar. So if there is a leap in April, it means that this period of time will be longer.
There is a natural law in the growth of crops, especially under the planting conditions in rural areas in the past, people depend on the sky for food and can only sow according to its inherent time. Therefore, the lunar calendar leap in April, the crops that are green and yellow are actually equivalent to adding insult to injury. When the wheat is not ripe, the grain has been sown, and there is probably not enough grain at home, so this is also the reason why the rural elderly don't like leap April. ?
Today, with the development of science and technology, this proverb has become less applicable. Now agricultural planting technology has become very advanced, the output of crops is getting higher and higher, and the problem of food and clothing for farmers has long been improved. Nowadays, people no longer depend on the weather to eat, but rely on their own food to make a living, so there is no so-called famine year.
However, due to different regions, leap April still has some special taboos. For example, it is forbidden to build houses, grow leeks and hatch geese and ducks in leap years in Heilongjiang, while Yucheng in Henan? Avoid planting October wheat in leap years? Said.
