Introduction to mangrove seed
Mang seed is a symbol of the maturity of awned crops such as wheat, and it is a solar term reflecting the phenomenon of agricultural phenology. By now, the wheat harvest season in Sichuan Basin has passed, and the transplanting of medium rice and sweet potato is coming to an end. In most areas, medium rice is turning green, and the seedlings are green and full of vitality. " The poem "the east wind has dyed 3000 hectares, and the egrets are flying everywhere" vividly depicts the beautiful scenery of the field at that time. When it comes to the grain growing season, the medium rice that has not been transplanted in the basin should be planted; If it is further delayed, the vegetative growth period of rice will be shortened due to the increase of temperature, and the growth stage will be vulnerable to drought and diseases and insect pests, so the yield will not be high. Sweet potato should be transplanted before the summer solstice at the latest; If sweet potato is planted too late, not only the effect of drought will be aggravated, but also the temperature will drop when autumn comes, which is not conducive to the expansion of potato block, and the yield will also be significantly reduced. This is the truth of the agricultural proverb "mang Zhong is busy planting".
