玉米是百色地区仅次于稻谷的主粮之一,但其产量年际之间起伏较大。百色地区春季光温条件较好,造成春玉米年际波动的主要因素是水分条件。由于玉米多种植在旱地,耕作层水分来源主要靠自然降水,田间持水量随降水量的增加直线增大,分析玉米产量与各生育期内降水量的关系,提供相应的科学数据作为栽培上的参考,对争取玉米高产稳产有利。
Corn is one of the staple foods in Baise, second only to rice, but its output fluctuates significantly from year to year. The conditions of light and temperature in spring in Baise area are good. The main factor that caused the interannual fluctuation of spring corn is the moisture condition. Due to the multi-planting of maize in the dry land, the main source of moisture in the plow layer is natural precipitation, and the field water holding capacity increases linearly with the increase of precipitation. The relationship between corn yield and precipitation during each growth period is analyzed, and corresponding scientific data is provided as cultivation For reference, to fight corn high-yield stable.
