(一) 解放以来,在毛主席革命路线指引下,我省苹果飞跃发展。至1975年,苹果株数增长36.6倍,产量增长80倍,深入开展“农业学大泰”和贯彻执行农业“八字宪法”,使苹果管理水平显著提高。全省各地亩产万斤丰产园相继涌现。但是,不少园片的高产未能持久,几年高产之后,产量下降,出现大小年结果。因此,研究稳定高产的规律和措施,一直是生产上迫切要求解决的问题。
(A) Since the liberation, under the guidance of Chairman Mao’s revolutionary line, Apple in our province has leapfrogged development. By 1975, the number of apples increased by 36.6 times and the output increased by 80 times. In-depth development of “agricultural science Tai Tai” and the implementation of the “eight-character constitution” of agriculture made the management level of apples significantly increase. Across the province, about one thousand kilos per mu yield garden have emerged. However, many high-yield failed to sustain long-term production. After several years of high output, output declined and year-to-year results appeared. Therefore, studying the law and measure of stable and high yield has always been an urgent problem in production.
