摘  要：
土壤水分和肥料管理是农业生产中最为关键的可控指标,是农作物高产稳产必不可少的因子。新疆北部阿勒泰草原的农牧业生产主要是在荒漠瘠薄的土地上开发和发展起来的,通过2015-2017年在阿勒泰地区福海县开展的膜下滴灌青贮玉米水肥耦合试验数据进行分析比较,初步得到青贮玉米不同水肥处理基本同时进入各个生育阶段;拔节期玉米的株高和茎粗随着施肥量的变化而变化;抽穗期,在不受旱和轻度受旱条件下,青贮玉米叶面积指数随施氮量的增加而增加;通过二元回归方程,合理的灌溉量、施肥量应分别是4 200 m~3/hm~2和195 kg/hm~2。

摘  要：
Soil moisture and fertilizer management are the most critical control indexes in agricultural production,and they are indispensable factor for crop yield and stability. The production of agriculture and animal husbandry in Northern Altay Prairie are mainly developed from the desert barren land. This paper analyzes and compares the water-fertilizer coupling test data of silage corn under drip irrigation in 2015-2017 in Fuhai County,Altay. It is found that under different water and fertilizer treatments,silage corn basically enters into each stage of growth at the same time; the plant height and stem diameter of maize at jointing stage are increased with the increase of fertilization amount; under the condition of no drought and mildly drought,with the increase of Nitrogen fertilizer amount,silage maize leaf area index is increased at heading stage. Through binary regression equation,it is proposed that the reasonable amount of irrigation and fertilization should be 4 200 m~3/hm~2 and 195 m~3/hm~2,respectively.
