为了探索晚稻(后季稻)早熟高产途径,无锡县东亭公社农科站选用既感温又感光的单熟晚粳东亭3号,于1980—1981两年,在11个生产队试验了采用单季稻的播期,通过寄秧,剥蘖移栽,用于后季稻栽插的方法,取得了“后季单季化”的效果。两年来单独核产的124.4亩,平均亩产759.6斤,比常规播栽的608.4斤(86.7亩),亩增151.2斤,增产24.8%,熟期提早6—7天。1982年在较大面积试验示范,核产11.3亩,平均亩产884.5斤,比对照常规播栽的21.5亩,增产14%,熟期早9天。现简介如下:一、方法(一)早播稀播。后季稻在当地单季稻播种的时期(5月底至6月2日)播种,比同品种的后季稻播
In order to explore the precocious and high-yielding ways of late rice (later season rice), Dongting Commune Agricultural Station of Wuxi County used single-ripening late rice Dongting No.3 which was both warm and sensitive. During the two years 1980-1981, 11 production teams were tested Using single-season sowing date, through the method of transplanting seedling, transplanting of tiller and transplanting for later planting and planting of rice, the effect of “single season of later season” has been achieved. In the past two years, 124.4 mu of single nuclear production was produced, with an average yield of 759.6 kg per mu, which was 151.2 kg more mu than 608.6 kg (86.7 mu) of conventional sowing, an increase of 24.8% and a maturity of 6-7 days earlier. In 1982 in a large area of demonstration, nuclear 11.3 acres, an average yield of 884.5 kg, 21.5 acres than the conventional planted plots, an increase of 14%, maturity early 9 days. Are as follows: First, the method (a) early broadcast sowing. Later season rice is sown at the time of local single season rice planting (from the end of May to June 2) and later than the latter season of the same variety
