1982年早造我所撒种栽培“双桂1号”高产示范片44.56亩,平均亩产1076.97斤,其中1块插秧高产栽培试验田,经地、县、所三级有关方面验收1.0314亩,全生育期122天,亩产1328.74斤,创全县常规品种高产纪录。其栽培技术如下: (1)疏播育壮秧。3月5日播种,亩播量54斤,按畦定量疏播匀播。秧地基肥每亩猪栏肥1600斤。秧苗2.5叶时亩施尿素5斤作断乳肥,4叶期亩施粪水1200斤,促分蘖生长。因早造前期气温不稳定,插前秧苗素质受些影响。秧龄26天,叶龄5.5片,分蘖数0.92％,茎粗0.55厘米,根长4.87厘米,新根数16.1条,苗鲜重15.4克(50科秧)。 (2)小科密植,插足基本苗。4月1日插秧,规格4×6寸,每科平均6.6苗,亩插基本苗16.5万。
As early as 1982, I planted and sowed “Shuangui 1” high-yield demonstration project 44.56 mu, average yield 1076.97 kg, of which 1 transplanting high-yielding cultivation experimental field, the prefecture and county, the three levels of inspection 1.0314 acres, all Growth period of 122 days, 1328.74 kg per mu, a record high yield of conventional varieties throughout the county. The cultivation techniques are as follows: (1) thinning seedling breeding. March 5 sowing, mu sowing 54 pounds, according to 疏 quantitative sowing evenly sowing. Seedling basal fertilizer per mu hurdle fat 1600 pounds. Miao 2.5 acres of seedlings when the urea fertilizer for grazing 5 kg, 4 acres of manure Shushui 1200 kg, and promote tillering growth. Due to the instability of the early pre-built temperature, the quality of the seedling inserted before it was affected. Seedling age of 26 days, 5.5 leaf age, tiller number 0.92%, stem diameter 0.55 cm, root length 4.87 cm, the number of new roots 16.1, fresh weight 15.4 grams (50 seedlings). (2) Small section close planting, plug foot basic seedlings. April 1 planting, size 4 × 6-inch, an average of 6.6 seedlings per acre, basic planting Mu 165,000.
