我国的杂交水稻,是在毛主席革命路线的指引下,在华主席的深切关怀下,很快发展起来的一项新的农业科学重大研究成果。一九七六年晚季,我队试种闽优一号15亩,平均亩产1088斤,其中一蚯高产田(共3亩地,全部采用三叉秧)平均亩产1178斤。大面积平均较常规品种闽榕4号(亩产860斤)每亩增产228斤;较红410(亩产850斤)每亩增产238斤。创我所晚季水稻高产新纪录。一、构成千斤稻产量因素的农艺性状特点:(1)在穗数上靠分蘖穗当家;晚季采取(10+5)×5宽窄行插植方式,亩插1.7万丛,丛插1～2本秧,亩插基本苗2.5～3.0万本,最高分蘖25.6～30.2万苗,每丛有效穗12.3～15.5穗,每亩18.9～22.8万穗,分蘖穗占总穗数80～90%以上,有效分蘖率70～75%。充分表现杂交水稻分蘖力强、成穗率高、依靠分蘖穗当家的特点。
Under the guidance of Chairman Mao’s revolutionary line, the hybrid rice of our country is a new major achievement in agricultural science that soon developed under the care of Chairman Hua. In the late seventy-seventh season, our team experimented with 15 mu of Minyou No.1, with an average yield of 1088 kilograms per mu. Among them, one high-yielding field of earth (totaling 3 mu, all using trigeminy seedlings) averaged 1178 kilograms per mu. Large-area average than the conventional varieties Min Rong 4 (mu yield 860 pounds) yield 228 kg per mu; more red 410 (mu yield 850 kg) yield 238 pounds per mu. Create a New Record for High Yield of Rice in Our Late Season. First, the characteristics of the agronomic traits that constitute the factors affecting the yield of jin rice: (1) The tillers were headed by the number of spikes; in the late season, (10 + 5) × 5 wide and narrow rows were planted with 17,000 clumps per mu, 2 seedlings, acres of basic seedlings inserted 2.5 to 30,000, the highest tiller 25.6 to 302,000 seedlings per panicle effective spike 12.3 to 15.5 spike, per acre 18.9 to 228,000 spike, tiller spike accounting for more than 80 to 90% of the total spike , Effective tillering rate of 70 ~ 75%. Full performance of hybrid rice tillering ability, the ear of becoming high, depending on the characteristics of tiller spike headed.
