【帝益肥】平顶山叶县玉米效果测产观摩

2020年9月24日,帝益肥工作人员在平顶山叶县廉村镇前崔村召开玉米测产观摩会,现场农户积极参与测产,对测产进行全程监督。

农户崔志光种植玉米使用帝益肥添鸿运黄腐酸锌镁配方28-6-6/cl/40kg,每亩地90斤。
测产观摩会选择在相邻地块、同时播种、同样种子的玉米地块。帝益肥工作人员和农户一起进入示范田和对比田随机挑选三个测产样本(一个样本5穗玉米),现场进行玉米测产工作。

(玉米测产方式)

(实测产量/公斤/亩=收货鲜穗重X鲜穗出籽率(%)÷收货样点株数X亩株数X【1-籽粒含水率(%)】÷(1-14%)(国家标准入库含水率)

注:最终实际产量参考农户实际入库产量。

测产数据

1、帝益肥(3个样本15穗)

毛穗重分别为:2.78斤、2.91斤、2,87斤,平均值为:0.57斤/穗;

粒重分别为:2.31斤、2.45斤、2.39斤,平均值为0.47斤/穗;

含水量均值为37%;

2、对比田(3个样本15穗)

毛穗重分别为:2.42斤、2.31斤、2.67斤,平均值为0.49斤/穗;

粒重分别为:2.05斤、1.90斤、2.16斤,平均值为0.40斤/穗;

含水量平均值为:37.5%;

 

3、产量计算(按照4000株/亩)

帝益肥亩产量=0.47*4000*(1-37%)/0.86=1377斤;

常规肥亩产量=0.40*4000*(1-37.5%)/0.86=1162斤;

通过计算,帝益肥亩产量比常规肥亩产量增加215斤,增产率达18.5%;

帝益肥玉米长势好,叶片宽厚,茎秆特别粗壮,抗倒伏能力强,霸王根也多,抗旱效果也好。玉米棒子大,整体也很均匀,颗粒饱满,增产效果明显。在生长过程中,病虫害少,多种中微量元素能够有效增强对玉米病虫害的抵抗力。

测产得出帝益肥亩产量为1376斤,对照田亩产量为1162斤,增产215斤,增产率为18.5%。

看到结果之后,农户对效果非常满意。认为帝益肥就是好,以后还要坚持使用。

帝益肥真正实现:节肥养地、保水抗旱、打破土壤板结,增产增收的效果。真材实料好肥料——首选帝益肥。
