The rape planted after the late rice harvest last year has entered the middle growth stage and is about to undergo flower bud differentiation and twitching and budding. This is a good time for fertilizing and promoting budding buds. At this time, fertilization should pay attention to controlling nitrogen fertilizer, increasing phosphorus, potassium, and fertilizer to prevent plant growth and reduce plant lodging, so that rape more than buds, rapeseed plump. The specific approach is as follows:
Partial application of nitrogen fertilizers should not be applied. Pure nitrogen fertilizers such as urea, ammonium nitrate, ammonium sulfate, ammonium chloride, ammonium bicarbonate, etc. cannot be applied. To use nitrogen, phosphorus and potassium fertilizers, increase phosphorus, potassium and fertilizer. Each acre applies 25-30 kg of nitrogen, phosphorus, potassium (15-15-15) compound fertilizer, 60-80 kg of superphosphate or calcium magnesium phosphate, 15-20 kg of potassium chloride or potassium sulfate. First, the whole field was filled with a "running horse water" and speed irrigation was performed. After the soil is wet, all the fertilizers are thoroughly mixed and mixed until they are applied to the field.
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.
