1988年,浙江省种植杂交晚稻汕优T28共9200亩,普遍获得好收成,其中象山县种植1750.5亩,平均亩产达到454.3公斤,比当家组合的汕优6号的410.5公斤,亩增43.8公斤,增长10.67%,50亩高产攻关田,平均亩产高达574.5公斤。夺取汕优T28高产的经验,主要是: 1.培育壮秧,适时移栽培育好壮秧,适时进行移栽是夺取汕优T28高产、稳产的基础。播种前,首先将种子用8%的四○二抗菌剂,以200倍溶液浸种48小时,然后再催芽播种。秧田施好基肥,要求亩施人粪10担,过磷酸钙25公斤,氯化钾25公斤。3叶期以后,用尿
In 1988, a total of 9,200 mu of late hybrid rice Shanyou T28 was planted in Zhejiang Province, with a good yield. Among them, 1750.5 mu was planted in Xiangshan County, with an average yield of 454.3 kilograms per mu, 410.5 kilograms more than that of Shanyou 6, an increase of 43.8 kilograms , An increase of 10.67%, 50 acres of high-yield field research, the average yield of up to 574.5 kilograms. Capture Shantou T28 high yield of experience, mainly: 1. Nurturing strong seedlings, timely transplanting seedling cultivation, timely transplanting is to seize Shanyou T28 high yield, stable yield basis. Before sowing, the seeds are first sown for 48 hours with 200% solution of 8% antifoam agent, and then germinated for sowing. Basal fertilizer applied seedlings, requiring Mushi Shi 10 Tam, superphosphate 25 kg, 25 kg of potassium chloride. After 3 leaves, use urine
