在水稻破口、灌浆初期,适当喷施速效性肥料,让叶面直接吸收,以及时补充水稻生长后期养份的不足,避免脱肥早衰,对增强水稻光合作用,提高结实率,增加千粒重有良好的效果。江西省的广大贫下中农和农业科研人员在毛主席无产阶级革命路线指引下,以阶级斗争为纲,深入开展“农业学大寨”的群众运动。他们认真贯彻农业“八字宪法”,大搞科学种田,积极开展了水稻叶面追肥技术的试验。三年的试验表明:叶面追肥是一项省肥、省工、 In the paddy breakage, the early filling, appropriate quick-acting fertilizers sprayed, so that direct absorption of the foliage, and timely supplement of late rice growth lack of nutrients to avoid premature de-fertilization, enhance rice photosynthesis, increase seed setting, increase 1000 weight good effect. Under the guidance of Chairman Mao’s proletarian revolutionary line, the vast numbers of poor and middle-level peasants and agricultural researchers in Jiangxi Province took the class struggle as the key link and carried out the mass movement of “learning from agriculture in Dazhai.” They conscientiously implement the “Character Constitution” of agriculture, vigorously scientific farming, and actively carried out the rice leaf top dressing technology test. Three years of experiments show that: foliage fertilizer is a provincial fertilizer, labor,
