Why do wheat seedlings have different color seedlings? Wheat is a grass plant widely cultivated all over the world, and it is also one of the staple foods of human beings. China is one of the first countries in the world to grow wheat. In the process of growing wheat, wheat is affected by natural conditions and cultivation measures, resulting in various abnormal color seedlings. Briefly talk about the causes and control measures of different colors of wheat seedlings, as follows. First, the reason for the emergence of different color seedlings in wheat seedlings 1. Soil drought (1) The soil in the wheat field is dry, mostly in wheat fields with insufficient bottom or running through the wind. (2) The characteristics are: wheat tillers are born slowly, leaves are grayish green, heart leaves are short, growth is slow or stagnant (also known as "reducing heart seedlings"), and the middle and lower leaves of wheat gradually turn yellow and dry, and the roots are few and thin. 2, nitrogen deficiency The nitrogen-deficient wheat seedlings are weak and erect, with reduced tillering and narrow leaves. The lower leaves start from the tip of the blade and gradually turn yellow and dry, and develop into the upper blade. 3, the soil board is hard The hard soil of the soil plate, because of the lack of soil and the lack of gas, the wheat roots are difficult to stretch, resulting in short yellow wheat leaves, tillers can not appear on time. Second, wheat heterochromatic seedlings prevention and control measures 1. For the wheat field with dry soil, it is necessary to combine watering and apply 15 kg of ammonium bicarbonate per mu. 2. For the wheat field with nitrogen deficiency, 7-8 kg of urea per acre, or 20-25 kg of ammonium bicarbonate, or 600-700 kg of human excrement, applied in the inter-row ditch or water. 3. For the wheat field hard wheat field, water it in time, and then plow the soil in depth to break the stiff layer.
