三、大力推广适用技术,增强抗灾能力旱作地区的减产或绝收,干旱是主要原因,但不是全部原因。广种薄收,粗放经营,忽视技术,从事掠夺式生产,降低土地抗灾能力等人为因素在减产因子中占有相当的比重。具体表现为: 1.严重缺苗:1989年郊区安庆沟乡马架子村焦明的山地谷(旱平地),行距45厘米,株距32厘米,每亩实有株数4492株,少于该乡玉米的留苗密度,
Third, vigorously promote the application of technologies to enhance resilience Drying areas to reduce production or income, drought is the main reason, but not all reasons. A variety of thin income, extensive management, neglect of technology, engaged in predatory production, reduce land resilience and other human factors in the production cuts occupy a considerable proportion. Specific performance: 1.
