在毛主席革命路线指引下,在“农业学大寨”群众运动推动下,我省农业生产不断发展,水稻高产社、队不断涌现。1973年以来,我们对水稻年产双千斤或一造超千斤的土壤条件和群众的培肥经验作了一些调查,提出初步的看法,现综述如下。高产稳产稻田的土壤条件要获得水稻高产,必须创造高产的土壤条件。一、土层厚度高产千斤稻田土壤的土层厚度,可分为有效土层厚度和熟化土层厚度。有效土层,即能为水稻生长直接或间接利用的土层。丘陵山区厚1.5尺以上,平原地区厚2尺以上。熟化土层或
Guided by Chairman Mao’s revolutionary line, under the impetus of the “agricultural learning Dazhai” mass movement, the agricultural production in our province continued to develop and high-yielding rice and rice units continued to emerge. Since 1973, we have made some surveys on the soil conditions for producing rice with an annual output of over one kilogram or over one kilogram, and the masses’ experiences in fertilizing. We have put forward some tentative suggestions and are summarized as follows. Soil conditions in a high and stable yield paddy To obtain high yields of rice, high yields of soil conditions must be created. First, the soil thickness Thicken rice soil depth of the soil can be divided into effective soil thickness and soil thickness. Effective soil layer, that is, the soil that can be directly or indirectly used for rice growth. Hilly and mountainous area is more than 1.5 feet thick, plain area is more than 2 feet thick. Soil maturation or
