水稻禾苗倒伏,势必妨碍养分的运輸,造成空壳多,結实率低,飽滿粒少,干粒重减輕,影响产量。根据在江西民間調查的材料分析:开花时期倒伏的,减产为五成,乳熟期倒伏的損失二成,黄熟期倒伏也会損失稻谷一成。所以及早做好田間管理工作,防止倒伏,是爭取早稻丰收的一个重要的問題。水稻倒伏的原因 1.施肥不当:有人說。“水稻倒伏是因为多施了肥”,这是不对的。肥料是禾苗生育的物質基础,
Rice seedlings lodging, is bound to hinder the transport of nutrients, resulting in more empty shell, low seed rate, full grain less dry weight loss, affecting the yield. According to the material analysis conducted in the folk investigation in Jiangxi Province, lodging during the blooming period reduced the yield to 50%, and the loss of lodging during milky ripening period reached 20%. Therefore, early field management work to prevent lodging is an important issue for the harvest of early rice. The reasons for rice lodging 1. Improper fertilization: Some people say. “Rice is lodging because it uses more fertilizer,” which is wrong. Fertilizer is the material basis of seedling growth,
