What is the growth process of corn?
2. Title stage. It refers to the stage of maize from jointing to tassel flowering, also known as vegetative growth and reproductive growth. During this period, the roots, stems and leaves grow vigorously, and the male and female ears differentiate and develop rapidly, which is the most vigorous period of maize growth and development in its life, and also the key period to determine the number of ears, ear size and grain number per ear. The central task of field management in this period is to promote strong and developed roots, stout stems, wide and thick leaves in the middle and fast closure.
3. Flowering period. From tassel flowering to grain maturity, it is also called reproductive growth period. The grain yield of maize is mainly formed by the platform products at this stage. Strengthening field management, ensuring fertilizer and water supply, ensuring normal flowering, pollination and fruiting, keeping green leaf area to the maximum, prolonging filling time, preventing disaster lodging, and striving for multi-grain, large-grain, whole-grain and high-yield are the central tasks at this stage.
