改良土壤,提高地力,是常年持续稳产高产的关键措施。多年来,我区人民遵照毛主席“农业学大寨”的伟大教导,发扬“自力更生,艰苦奋斗”的革命精神,战天斗地,大搞农田基本建设,改变农业生产基本条件,对粮食持续增产起到很大作用。但一般肥料缺乏,部分地方尚沿用旧农具、老方法进行耕作,致使一些基本农田处于土层薄、肥力低、保水保肥性能差的不良状态。近年,改良土壤,提高地力,已为各级领导所重视,一个深翻改土、垫土压沙、引洪压碱的群众运动蓬勃开展,涌现出一批先进典型,成绩显著。为了迎接农业跃进的大好形势,对深翻改土和抗旱耕作方面谈一些意见。一、基本农田深翻、深施肥,培肥土壤深翻能疏松土壤,破除坚实的犁底层,改变土壤物理性状,降低容重,增加孔隙度,增
Improving soil and improving soil fertility are the key measures to maintain a steady and high yield throughout the year. Over the years, the people in our region followed the great teachings of Chairman Mao’s “Studies in Agriculture” to promote the revolutionary spirit of “self-reliance and arduous struggle”, fought the war days, vigorously promoted farmland infrastructures, changed the basic conditions for agricultural production, Great effect. However, the general lack of fertilizers, some still follow the old tools, the old method of farming, resulting in some of the basic farmland in a thin layer, low fertility, poor water and fertilizer performance of the poor. In recent years, improvement of soil and improvement of land resources have been taken seriously by leaders at all levels. A mass movement of deep soil improvement, soil compaction and sediment stimulation has brought about vigorous development and a number of advanced models have emerged with remarkable achievements. In order to meet the excellent situation of agricultural leap forward, we should talk about some suggestions on deep soil improvement and drought-resistant cultivation. First, the basic farmland deep plowing, deep fertilization, fertilization soil deep plowing can loosen the soil, get rid of a solid plow bottom, change the physical properties of the soil, reduce bulk density, increase porosity, increase
