" 4-4-10-3 " BP neural network structure, the inputs of the model are soil nutrient ( N, P and K ) and yield goal, the outputs are application rate of fertilizer ( N, P and K ). 44103网络结构的BP网络变量施肥决策模型以土壤养分(速效氮、速效磷和速效钾)含量和目标产量为输入,以氮、磷、钾施肥量为输出。
The zoned result can be used as yield goal map for preplant or in-season fertilize recommendation algorithms in precision agriculture. 分区结果可以直接作为精准农业目标产量分区图,用于作物种植前或产中适时肥料推荐管理决策。
Commercial application shows that when the olefin content of FCC naphtha is near the target value 39 %, and the amount of naphtha reprocessing is small, light fraction reprocessing is favorable to increase the yield of goal product. 工业应用表明,在汽油烯烃含量接近目标值(目标值为体积分数39%)时,汽油回炼量小,此时回炼轻馏分汽油有利于目的产品收率的提高;
The average liquid yield and goal product ( aviation fuel plus diesel fuel ) yield were 96. 7 % and 72. 34 %, respectively; 平均液收达到96.7%;目的产品的收率为72.34%;
To increase yield is the main goal in wheat breeding. 提高产量始终是小麦育种最基本的目标。
