为了探明鄂晚3号适宜的播种期和插秧期,我们于1974—1975年进行了分期播种和插秧试验。播种期:从5月29日到7月3日,每7天播一期,采用水育秧,每亩播种量150斤。插秧期:从7月15日到8月15日,每10天(或11天)插一期,同一个插期移栽3—4个播期的秧苗。移栽后田间管理与一般大田相同。现据两年试验的平均结果简报如下: 试验结果与讨论 1.播、插期与产量的关系 鄂晚3号感光性强,作双晚栽培,约在8月10—15日左右开始进入幼穗分化期。因此,插秧期越早,由于本田营养生长期相应加长,营养体生长较好,穗大粒饱,产量越
In order to ascertain the appropriate sowing date and planting time of No. 3 in Hubei Province, we conducted staged sowing and transplanting experiments in 1974-1975. Sowing period: from May 29 to July 3, a broadcast every seven days, the use of watering seedlings, planting acre per acre 150 pounds. Transplanting period: from July 15 to August 15, every 10 days (or 11 days) insert a period, the same period of transplanting 3-4 sowing seedlings. Field management after transplanting is the same as that of general field. The results of the two-year trial results are summarized as follows: Test results and discussion 1, sowing and interbreeding and yield relationship E night 3 strong photosensitivity for double-night cultivation, about August 10-15 start entering young Spike differentiation period. Therefore, the earlier the seedling transplanting period, due to a corresponding extension of the vegetative growth period of Honda, vegetative growth is better, the spike large grain full, the yield
