安阳县曲沟镇位于安阳县西部,常年种植玉米面积3335万平方米左右,经过近几年来我们的生产实践,蓄住天上水,保住土中墒,经济有效地提高水分利用率,是实现旱地玉米增产的关键。一、品种选择及处理抗旱品种具有适应干旱环境的形态特征,例如种子大,根茎伸长力强,能适当深播;根系发达,生长快,入土深,根冠比值大,能利用土壤深层的水分;叶片狭长,叶细胞体积小,叶脉致密,表面茸毛多,角质层厚。玉米抗旱品种叶片细胞原生质的黏性大,遇
Quyang Town, Anyang County is located in the west of Anyang County. The annual planting area of maize is 33.35 million square meters. After our production practice in recent years, it has saved the heavenly water and saved the soil moisture, thus economically and effectively increasing the water use efficiency. The key to yield corn. First, the species selection and handling Drought resistant varieties have adapted to the morphological characteristics of the arid environment, such as large seeds, rhizome elongation strong, can be suitable for deep sowing; developed root system, rapid growth, deep into the soil, root and shoot ratio, can use deep soil Moisture; leaves long and narrow, leaf cells small, dense veins, surface hair more, cuticle thick. Maize drought-resistant varieties of leaf cell protoplasm sticky big case
