紫色土氯锌锰与氮磷钾配施对小麦的营养效应研究

STUDY ON THE EFFECT OF CL,Zn,Mn WITH N,P,K COMBINATIONS TO THE NUTRITION OF WHEAT IN PURPLE SOIL

含氯复(混)合肥对小麦产量和品质无不良影响。在钙质紫色土上施用氯铵与磷、钾、锌、锰配制的含氯复(混)合肥和用尿素配制的非含氟复(混)肥同样优质高产。当土壤有低锌为0.3ppm时,施锌肥对小麦显著增产。当土壤有效锰为13.3ppm时,施锰肥未见增产。施锌可提高小麦蛋白质和淀粉含量。施磷明显降低了小麦植株含锌量。

Chlorine in compound fertilizer has no side effect to the yield and quality of wheat. The use of NH_4Cl with P, K, Zn and Mn combined with compound fertilizer including chlorine and the use of urea with P, K, Zn and Mn combined with compound fertilizer without chlorine have produced good quality and yield. The application of Zn increases wheat yield very significantly when its avaiiable concentration is 0.3ppm in the soil. Mn has no sigificant effect to wheat yield when its available concentration is 13.3 ppm in the soil. Zn markedly increases protein and starch content in wheat grain. The application of P markedly decreases the content of Zn in wheat plant.
