Effect of Diammonium Phosphate on Dry Matter Accumulation and Pods Growth of Different Mungbean Varieties

In order to explore high yield cultivation measures of mungbean with different plant types,taking two mungbean varieties with upright and semi-trailing plant types as test materials,the effect of diammonium phosphate on dry matter accumulation and pods growth was anslyzed by applying different amounts of diammonium phosphate(0,150,225kg·hm-2).The results showed that the dry matter accumulation of roots,stems,leaves and pod length of the third fruit branch per plant of different plant types of mungbean were the highest by applying appropriate amount of diammonium phosphate,excessive amount was higher,and the lowest was no fertilizer(CK).The dry matter accumulation of roots in Liaolyu 6was lower than Liaolyu 5,time and amount of the maximum rate of dry matter accumulation in stems and leaves showed that Liaolyu 6was earlier and higher than Liaolyu 5.The pod length of the third fruit branch per plant showed that Liaolyu 6was longer than Liaolyu 5.
