在毛主席无产阶级革命路线指引下,在深入开展农业学大寨的群众运动中,我县实现了大面积改制,粮食产量大幅度增长。但是,随着复种指数的提高,肥料不足的矛盾十分突出。因此,广大贫下中农在坚持自力更生、大积大造自然肥料的同时,对化学肥料的经济施用,提高肥料利用率,达到既经济施肥,又提高产量的问题,引起了重视。因此,我所1976年在双季早稻上进行了深层追肥技术的初步研究。现将试验情况综合如下。
Under the guiding principle of Chairman Mao’s proletarian revolutionary line, in carrying out the mass movement to learn from Dazhai in agriculture, the county achieved a large-scale restructuring and its grain output increased substantially. However, with the improvement of multiple cropping index, the contradiction between insufficient fertilizers is very prominent. Therefore, the majority of poor peasants and middle peasants are paying more attention to economic self-reliance and large-scale production of natural fertilizers, economic application of chemical fertilizers, and higher utilization rates of fertilizers to achieve both economic and fertilizing as well as higher yields. Therefore, in 1976, we conducted a preliminary study of deep dressing techniques in double-season early rice. Now the test is summarized as follows.
