党中央“关于深耕和改良土壤的指示”中指出“水、肥、土、种、密,中心是土,就是深耕”。1958年的农业生产实踐,充分显示了深耕在农业增产中的巨大作用,稻田增产的效果,有力的駁斥了“水稻是淺耕作物,不需要深耕”的观点,但是,稻田与旱地在深耕方面各有其不同的特点,如何根据稻田的特点,进行深耕,管理,因地制宜制訂出合理的深耕深度、方法、时間、施肥等問題,猶待进一步的研究,这里仅就1959年我們在天門县九真人民公社柳河管理区,师生与农民共同种的九塊早稻試驗田,观察和記載的資料,对目前情况下,早稻深耕深度問題,提出如下初步看法,以供参考討論:
The CPC Central Committee’s “Directive on Deep Soil Improvement and Soil Improvement” states that “water, fertilizer, soil, seed and soil are dense and the center is soil, that is, deep plowing.” The practice of agricultural production in 1958 fully demonstrated the great role of deep plowing in increasing agricultural output, the effect of increasing paddy field output, and strongly rejected the view that rice is a shallow-tillage crop and does not require deep plowing. However, According to the characteristics of paddy fields, how to make deep plowing and management, and formulating reasonable deep plowing depth, method, time and fertilization according to local conditions and so on, we still have to wait for further research. County nine real people’s commune Liuhe management area, teachers and students of common cropping nine early rice experimental field, observed and documented information on the current situation, the depth of deep-rooted early rice, put forward the following preliminary views for reference:
