摘要
通过正交试验,研究了优质早籼稻"赣早籼37号"的高产配套栽培技术。结果表明:4个因素对产量的影响大小依次为基本苗数>肥料用量>肥料种类>育秧剂种类。基本苗数和育秧剂对有效穗数、实粒数、总粒数和千粒重影响较大,基本苗数和肥料种类对结实率和成穗率影响较大。最佳栽培技术组合为:采用壮秧剂塑盘育秧,抛栽基本苗数为142.5万/hm2,施用总有效成分为265kg/hm2的有机无机复混肥(N∶P∶K=13∶6∶11)。该技术组合可获得6749.7kg/hm2的高产量。
The coordinative high-yielding cultural techniques of quality early indica rice 'Ganzaoxian 37' were studied through orthogonal test. According to the influence of four tested factors on the yield, they were arranged as follows: number of basic seedling>quantity of fertilization>kind of fertilizer>kind of seedling-cultivating agent.The number of basic seedling and seedling-cultivating agent had greater influence on the number of effective panicle, filled grain and total grains as well as 1000-grain weight, the number of basic seedling and kind of fertilizer had greater influence on the setting rate and rate of earbearing tiller.The best cultural technique combination for high yield is as follows:using seedling-strengthening agent to raise seedling on plastic tray, throwing 1425 thousands basic seedlings per hm\+2 for cultivation, applying the organic and inorganic compound fertilizer which contains 265kg/hm\+2 total effective composition(N∶P∶K=13∶6∶11). Applying above cultural technique combination could obtain 6 749.7kg/hm\+2 of high yield.\;
