丰抗十号小麦规范化栽培技术的研究

为了寻求丰抗十号小麦在冀东平原的优化栽培方案,根据农业系统工程的原理,应用二次正交旋转回归组合设计方法,把对小麦生长影响较大的可控因子——播期、播量、灌水、施肥时期和施肥水平作为变量.选择产量、净产值等六项指标为目标函数,通过多点试验、微机运算,完成了数千个组合的动态仿真和统计分析.筛选出亩产200、300、400公斤左右净产值在80、100、120元以上的三个区组的最佳农艺组合方案.同时,根据本地农业生产条件和小麦生育要求,找出五个不同产量区间的优化栽培方案.

A STUDY ON THE STANDARDIZED CULTURAL TECHNIQUE OF FENGKANG 10 WHEAT

In order to find an optimum cultural program for Feng Kang 10 wheat in the Ji Dong Plain, such controllable factors-sowing season, sowing rate, irrigation, the time and level of fertilization-as exert great influence u-pon wheat production, were selected as variants by the use of quadratic quadrture/rotational regression combination design based on the principle of agricultural system engineering. Six indice inlcduing yield and net value of production were selected as target functions. Pneumatic imitation and statistical analysis of several thousand combinations were completed through multi-spot experiments and mini-computer computation. Three agronomic Combinations were found with yields of about 200, 300, and 400 kilograms. mu-1. and net production values of 80, 100, and 120 yuan.mu-1. Optimum cultural programs for 5 yield areas were found in accordance with the local conditions of agricultural production and the growth requirements of wheat.
