依据农鉴1号小麦分蘖力极强的特点,我们采用超低量稀播的种植方法。试验于1991年在安徽农业技术师范学院农场进行。按设计密度应为11884株/亩,种子千粒重41克,理论播量0.48公斤/亩。实际用种量为0.42公斤/亩,密度为10244株/亩。播前精细整地,用开沟器开垄沟(行),足墒单粒点播,盖土后种子深度为3～5厘米。沟(行)距17厘米,株(粒)距33厘米,各行种子位置错开。最后用开沟器划破垄背,用分开的土覆盖种子、耙平。10月12日播种,10月18日出苗,次年3月11日补苗移栽一次,6月2日成熟。三块试验地的亩产,分别为530.7公斤、486.5公斤和449.0公斤。本试验结果表明,农鉴1号分蘖力极强,
According to Nongjian No. 1 wheat tillering extremely strong features, we use ultra-low-volume thin sowing cultivation methods. The experiment was conducted in 1991 on the farm of Anhui Agricultural Technology Normal College. According to the design density should be 11,884 plants / mu, seed grain weight 41 grams, theoretical sowing 0.48 kg / mu. The actual use of 0.42 kg / acre, density of 10244 plants / mu. Fine pre-sowing, open ditches with open ditch (line), enough moisture single-pitted, covered with soil depth of 3 to 5 cm. Gully (row) distance of 17 cm, strain (grain) from 33 cm, the rows of seeds staggered. Finally ditched the ridge with a ditcher, covering the seed with separate soil and raking it flat. October 12 sowing, October 18 emergence, the next year March 11 seedlings transplanted once, June 2 mature. The three plots of trial yields were 530.7 kg, 486.5 kg and 449.0 kg respectively. The test results show that Nongjian 1 strong tillering ability,
