植物的生长发育和成熟,至少需要三个主要因素,即日光、水、化学元素。化学元素是植物的营养物质,植物用它们构成细胞和原生质,供给力能和调节生理活动。营养失调,将影响植物的生活。根据化学分析,每100市石玉米植株(穗、茎、叶和根)的干重,其中约含炭4,330市斤,氮137市斤,钾104市斤,磷33市斤,硫63市斤,镁41市斤,钙41市斤,铁1.7市斤,锰0.25市斤,硼0.05市
Plant growth and maturity, at least three major factors, namely, sunlight, water, chemical elements. Chemical elements are the plant’s nutrients, plants use them to form cells and protoplasm, supply power and regulate physiological activity. Malnutrition will affect plant life. According to the chemical analysis, the dry weight of stone corn plants (spike, stem, leaf and root) per 100 municipalities includes about 4,330 kilograms of carbon, 137 kilograms of nitrogen, 104 kilograms of potassium, 33 kilograms of phosphorus and 63 kilograms of sulfur 41 kg of magnesium, 41 kg of calcium, 1.7 kg of iron, 0.25 kg of manganese, and 0.05 of boron
