在毛主席无产阶级革命路线指引下,我组教师和学员坚持《五·七》方向,深入农村,开门办学,认真学习和总结贫下中农施用食盐的历史经验,探索氮肥增效剂能够提高肥效的原理,在碳酸氢铵化肥中配加少量食盐,制成食盐增效球肥,按深层施肥的办法塞施于水稻田中,可以显著提高碳铵的肥效。一、增产效果:为了探明食盐增效球肥对水稻的增产效果,我们在沙县洋坊冲积性水稻土上进行了两年的田间试验。试验结果证明,水稻施用食盐增效球肥的,肥效持久,稻苗青绿粗壮,增产效果显著。一九七四年早季用
Guided by Chairman Mao’s proletarian revolutionary line, our group of teachers and students adhered to the “5.7” orientation, went deep into the countryside, opened their doors to schools, conscientiously studied and summarized the historical experience of applying salt to the poor and under-middle peasants, and explored the effectiveness of nitrogenous fertilizer synergists Principle, in the ammonium bicarbonate fertilizer with a small amount of salt, made of salt synergistic ball, according to the method of deep fertilization plug in paddy fields, can significantly improve the efficiency of ammonium bicarbonate. First, the effect of increasing yield: In order to ascertain the yield of salt-enhanced fertilizer on rice yield, we conducted a two-year field experiment on alluvial paddy soil in Yangfang, Shaxian County. Test results show that the application of salt fertilizer salt rice, long lasting fertilizer, rice seedling green thick stalks, yield a significant effect. Used in early 1974
