随着节水灌溉技术的发展,低压软管灌溉系统,以其成本低、节水、增产和提高土地利用率等优点,迅速在北疆棉区推广。 一、试验结果与分析 1、对棉花生育进程的影响。软管灌和常规灌出苗期和现蕾期无多大差异,花铃期软管灌提前2～5天,吐絮期提前1～4天。 2、对棉花生长发育的影响。7月10日调查,软管灌较常规灌棉花株高平均高4.82厘米,单株主茎叶片数、果枝数、现畜数、开花数和结铃数分别增加1.27片、0.37台、3.48个、1.46朵和0.3个。
With the development of water-saving irrigation technology, low-pressure hose irrigation system, with its low cost, water saving, increase production and improve land utilization and other advantages, the rapid promotion in the northern cotton area. First, the test results and analysis 1, the impact on the process of cotton birth. Hose irrigation and conventional pumping seedling and budding period is not much difference between the flowering period hose irrigation 2 to 5 days before the boll flow stage 1 to 4 days in advance. 2, the impact of cotton growth and development. July 10 investigation, irrigation than conventional cotton irrigation plant height average height of 4.82 cm, the number of main stem leaves per plant, fruiting branches, the number of livestock, flowering and boll number increased by 1.27, 0.37 units, 3.48 , 1.46 and 0.3.
