| Abstract: | The effects of different irrigation conditions on nutrient absorption of maize plants were studied.The experiment was carried out in Moshan,Shandong Province.On the basis of the integration of water and fertilizer,the law of nutrient absorption of maize plants under different irrigation methods was investigated.Four irrigation methods,including non-irrigation(CK),gully irrigation(T1),spray irrigation(T2)and drip irrigation(T3),were set up.The results showed that the dry matter accumulation of maize at jointing stage,wire-drawing stage and maturity stage showed a trend of T3>T2>T1>CK.The absorption of N,P and K showed a trend of T3>T2>T1>CK.The absorption of calcium and magnesium was T3>T2>T1>CK.The absorption of Fe,Mn,Cu and Zn showed a trend of T3>T2>T1>CK.In addition,the dry matter accumulation in the whole growth period of maize was the highest in T3 treatment,which was 14447.20 kg/hm2.The nutrient accumulation of N,P and K was the highest in T3 treatment,which were 207.73 kg/hm2,178.18 kg/hm2and 204.65 kg/hm2,respectively.The nutrient accumulation of calcium and magnesium in T3 treatment was the highest,which were 22.55 kg/hm2and 7.62 kg/hm2,respectively.The nutrient accumulation of Fe,Mn,Cu and Zn was the highest in T3 treatment,which were 8967.55 g/hm2,1040.53 g/hm2,406.65 g/hm2and 1182.65 g/hm2,respectively.In conclusion,compared with furrow irrigation and sprinkler irrigation,drip irrigation is better for nutrient absorption of maize plants,can better promote dry matter accumulation and nutrient absorption during maize growth.So it is an appropriate irrigation method for maize planting. |
