摘要
通过3年的山区旱作农业综合配套技术示范研究,总结出了适于井陉山区旱作特点的综合技术措施:进行山区旱作类型分区;采取系统蓄墒保墒;调整作物结构;选用抗旱优种;科学合理施肥;传统与现代旱作技术并用;工程与生物措施并举,使试区亩产117.4kg的低产旱田提高到273.6kg的水平。
The comprehensive technical package suitable to rainfed agriculture in Jingxingmountain area has been summed up through 3 years'demonstration studies of perfectionof comprehensive agro-techniques in rainfed agriculture in mountain area.The wholetechincal package should include classification of rainfed agricultural zones,adaptationof systematic moisture storage and moisture conservation,readjustment of crop struc-ture,selection of fine drought-resistant crop varieties,scientific and rational fertiliza-tion,simultaneous utilization of traditional and modern rainfed agrotechniques,and si-multaneous combination of bilogical measures with engineering practice.In this way,per mu yield of 117.4 kg in poor rainfed land can be raised to 273.6 kg per mu.
