玉米地膜覆盖栽培是提高地温有利早种早收,保墒防渍,保证植株正常生长发育,增产增收的一项新技术。现将要点介绍如下。1.选用良种根据海拔高低、气候条件选用适宜杂交良种,在海拔1500米以下地区,选用中熟或中晚熟的杂交种,如中单2号、七三单交、京杂6号、恩单2号、成单6号、峡玉1号等组合为宜;在海拔1500米以上地区,可选用中早熟的杂交种,如成单4号、恩单3号、莫黄单交、南黄单交等组合为宜。
Maize mulching cultivation is to improve the benefits of early warm and early harvest, soil moisture, anti-stain, to ensure the normal growth and development of plants, increase production and income of a new technology. The main points are introduced below. 1. Selection of elite according to the altitude, the climatic conditions of the selection of suitable hybrids, in the area below 1,500 meters above sea level, the choice of medium or late hybrids, such as in the single 2, 7 3 single pay, Beijing hybrid 6, No. 2, Cheng 6, Xiaoyu 1 and other combinations are appropriate; in the area above 1,500 meters above sea level, the choice of early maturing hybrids, such as into a single No. 4, single No. 3, Mo yellow single cross, South yellow Single pay combination is appropriate.
