棉花喷硼对促进根系发育,参与碳水化合物合成、运转、积累、体内氮素代谢,加速花粉萌发,花粉管伸长,防止蕾铃脱落,增强棉株抗逆性,提高产量,有着重要作用。近年来,氮、磷、钾等化肥使用量增加,土壤中硼素相对减少,作物需硼更加紧迫。所以,大力推广棉花喷硼技术,是提高棉花产量和品质的一项简便易行,增产增收的有效措施。
Cotton boron spraying plays an important role in promoting root development, participating in carbohydrate synthesis, operation and accumulation, nitrogen metabolism in vivo, accelerating pollen germination, pollen tube elongation, preventing buds from falling off, enhancing cotton plant resistance and increasing yield. In recent years, nitrogen, phosphorus and potassium fertilizer use increased, the relative reduction of boron in the soil, crop boron is more urgent. Therefore, vigorously promote cotton boron spraying technology is to improve cotton yield and quality of a simple, effective measures to increase production and income.
