实行水稻高产高效益栽培,使农业经济与农艺高度结合,是农业集约经营的体现,也是今后发展水稻生产的长期战略,经过认真分析海城市的自然特点,在总结已有经验的基础上,1986、1987两年大力推行了水稻高产高效益综合栽培技术,两年累计开发稻田35万亩,平均亩产596.2公斤,比前三年平均每亩增加81.7公斤,增产率14.4％,总增产稻谷2858万公斤,每亩生产成本比前三年平均降低31.7元,增产节支总纯收益为2854.16万。两年所采取的主要技术措施有以下十项:一、发挥热量资源优势,恰当安排高产良种海城市的热量资源比较充足,适宜种植中晚熟水稻品种,经过前几年的试种,认为杂交稻黎优57和秀优57较好,具有根系发达、抗旱力和分蘖力强、穗大、粒多、粒重、产量高的生育和产量优势。秀优57的熟期和米质还略优于黎优57,因而群众乐于种植,1986年推广杂交稻13万亩,占总开发面积的86.7％。其中黎优57为7.2万亩,1987年12
Implementation of high yield and high efficiency cultivation of rice, the agricultural economy and agronomic highly integrated, is the embodiment of agricultural intensive management, but also the future development of long-term rice production strategy, after careful analysis of the natural characteristics of the city of Haicheng, based on the existing experience, based on the 1986 In 1987 and 2002, the comprehensive high-yielding and high-yielding rice cultivation technology was vigorously promoted. In the past two years, a total of 35 million mu of paddy fields were developed with an average yield of 596.2 kilograms per mu, an increase of 81.7 kilograms per mu over the previous three years with an increase rate of 14.4% and a total yield of 2858 The production cost per mu reached an average reduction of 31.7 yuan over the previous three years, with a total net income of 28.54 million yuan. The main technical measures adopted in the past two years are the following ten items: First, giving full play to the advantages of caloric resources and appropriately arranging high-yielding varieties of seeds Haicheng City, with sufficient heat resources, is suitable for growing middle-late-maturing rice varieties. After years of trial planting, Liyou 57 and Xiuyou 57 were better, with the advantages of root system development, drought resistance and tillering ability, spike size, grain size, grain weight and high yield. The sowing date and quality of Xinyou 57 was slightly better than that of Liyou 57, so the masses were willing to plant them. In 1986, 130,000 mu of hybrid rice was promoted, accounting for 86.7% of the total area under development. Liyou 57 of which 72,000 mu, 1987 12
