程序先看植株后验根,观察叶片分老新,种果亦显缺素状,非是缺素皆外因。观植株缺素植株小,硫镁见后期。铁镁硫失绿,铜锰硼变形;中、微量元素,病在顶端幼嫩部;缺磷分蘖少,缺钾倒伏穗不多;缺钾钼铜钙,易染病虫害。

The program first look at the plant after the root test, observe the leaves of the new, the fruit is also deficient, non-externality are non-exogenous factors. View plants lack of plantlets, magnesium and magnesium see later. Fe-Mg-L out-of-green, copper-manganese-boron deformation; medium and trace elements, the disease in the top of the tender Ministry; less phosphorus deficiency and tillering less potassium deficiency lodging less;
