Rice growth to see nutrition
Nitrogen deficiency: Plants are short, with few tillers, small and upright leaves, yellowish-green leaves, short stems, small grains, and high fruiting rate.
Phosphorus deficiency: often in the early period of fertility, the formation of "stiff seedlings", manifested as slow growth, no childbirth or delayed delivery, seedlings are not weak hair trees. The leaves are dark green or grayish green with a purplish leaf shape, long leaves, small leaves, and slightly curled leaves. Old roots turn yellow, new roots are small and slender, and black rots when severe. The maturation period is inconsistent, the spikes are small, the grain weight is low, and the empty shell rate is high.
Too much phosphorus: often induce zinc deficiency in rice. Therefore, the symptoms of excessive phosphorus are similar to that of zinc deficiency. There are few tillers, and the "freezing seedlings" do not develop. The leaves are green, gradually turning yellow and white along the middle veins of the leaves, brown spots appear in the old leaves, and the entire leaves are brown in the late growth stage. Root growth is slow, and the whole plant will die when severe.
Vitamins are a type of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. In terms of physiological functions, vitamins are neither a raw material for tissues nor a substance for supplying energy, but they are an indispensable substance for the body. It has many types and different chemical structures. Most of them are the components of the coenzyme (or prosthetic group) of certain enzymes. They are the indispensable compounds for maintaining the normal growth (growth, health, reproduction and production function) of the body. It plays a catalytic role in the body to promote the synthesis and degradation of major nutrients (proteins, fats, carbohydrates, etc.), thereby controlling metabolism. Vitamins are essentially low-molecular organic compounds. They cannot be synthesized in the body, or the amount synthesized is difficult to meet the needs of the body, so they must be supplied from the outside. The daily requirement of vitamins is very small (usually measured in milligrams or micrograms). They are neither a raw material for body tissues nor a substance for energy supply in the body. However, they do not regulate material metabolism, promote growth and development, and maintain physiological functions.
