摘要
通过对超产二号优质品种不同肥料种类和数量、不同插秧密度与产量等性状的两年回归试验分析得出,超产二号属于高产优质品种。从产量方程来看,平均产量应为8797.8kg/hm2。对超产二号产量影响最大的栽培因素为施磷量,每公顷113.4～129.1kg,其次是施氮量,每公顷以139.2～143.4kg为宜,施钾肥作用较小,每公顷67.1～84.3kg,插秧方式以30cm×(13.8～15.8)cm产量较高。单因素效应分析,产量与4个栽培因素之间均呈二次曲线关系。
Chaochan2is a rice variety of high yield and high quality.Through regression analysis of two years data between different fertilizer sorts and quantities,different density of trans-plants and yields.Its mean yield was8797.8kg /hm 2 ,from yield equation.The Cultivation factors affected the yield of Chaochan2were as follows.The primary factor was application quantity of phosphoric fertilizer,113.4～129.1kg /hm 2 ;the secondary factor was application quantity of ni-trogenous fertilizer,139.2～143.4kg /hm 2 ;the third factor was application quantity of potassium fertilizer,67.1～84.3kg /hm 2 .When the density of transplants was30cm×13.8cm,the yield was the highest.In addition,the results of the individual factor effect analysis showed that the relation between yield and each of the four individual factors was quadratic curve.
