1986～1988年,我们采用百亩连片高产栽培,结合汕优63综合农艺措施数学模型的建立与分析,总结了汕优63亩产600公斤的栽培技术,並在大面积杂交稻生产上推广应用,取得了显著增产效果,使我县15万亩汕优63亩产连续两年超过600公斤。 (一)主要生物学指标 1.茎蘖动态:汕优63亩产600公斤,既要有足够的穗数,又要有整齐的大穗。这一目标是通过培育壮秧,栽足基本苗,促进分蘖早发来实现的。三年来,高产田的共同特点是:每亩栽足8～9万基本苗(包括3叶以
From 1986 to 1988, we used 100 mu contiguous yield high-yield cultivation, combined with the establishment and analysis of the mathematical model of Shanyou 63 comprehensive agronomic measures, summed up the cultivation techniques of 600 kg per mu in Shanyou 63 and promoted the production of large-area hybrid rice Application, and achieved remarkable yield increase effect, so that I County 150,000 acres of Shanyou 63 acres for more than 600 kilograms for two consecutive years. (A) of the main biological indicators 1. Stem tiller dynamic: Shanyou 63 acres of 600 kg, both enough spikes, but also have a neat big spike. This goal is achieved by cultivating strong seedlings, planting enough seedlings, and promoting early tillering. Three years, the common features of high yield fields are: planting 80,000 to 90,000 seedlings per acre (including 3 leaves
