How many solar terms are there in planting trees a year?
"The spring rain shakes the spring and the valley days, the mountains and rivers in summer are hot in summer, the autumn dew is frosty, and there is snow and ice in winter." This is a song about the 24 solar terms of the Lunar New Year, which is widely circulated in China. March 12 Arbor Day is generally located between the vernal equinox and the Tomb-Sweeping Day air, which is the time when the grass grows and everything sprouts in spring.
Afforestation in spring should be carried out according to the actual situation and solar terms in various places, and it is not necessary to cut across the board in the north and south. "Arbor Day is coming, and the climate difference between north and south is still very big. In terms of solar terms, large-scale tree planting in the north is more than a month later than that in the south. April is usually a good time to plant trees, but some places in the south began to plant trees in February. For the southern region, the rainy season is also a good season for planting trees. No matter from the climate or soil moisture, planting trees at this time is very beneficial to the survival of seedlings. Therefore, when engaging in afforestation propaganda, we should remind everyone to learn to use various favorable climatic conditions and choose suitable seasons for afforestation. "
