Key points of rice management in August
First, apply rice field herbicides at the right time. In order to eliminate weeds in rice field, herbicides should be applied timely, which can not only save labor (no-tillage) and money (about 2 yuan per mu), but also solve the contradiction between weeds and rice seedling growth, which restricts the normal growth and development of rice seedlings. The specific method is to sprinkle 20 grams of straw long or 100 grams of urea (combined with topdressing), fine sand or dry Ni powder to dry dew for 7 days after insertion, and to keep the shallow water layer for 5 days.
