Abstract
Field experiment was conducted on yellow soil in Huaxi district of Guiyang. Observating and analyzing low straw、medium straw、high straw、plastic cover of No-tillage and ploughing influenced on Guidan No.8 corn NPK uptake and output. To evaluate and select the best combination of no-till coverage model.The results showed:(1) No-tillage with maize plants absorbed the amount of nitrogen, phosphorus, potassium on average 9.73%, 11.77% and 26.25% higher than ploughing.(2) Nitrogen in the plant vegetative growth stage were mainly concentrated in the stems and leaves, mainly transfer and accumulate to grow organs between reproductive growth; phosphorus accumulation and distribution was not the same with nitrogen, in the redistribution, the accumulation of phosphorus in culm and sheath was transported to the clusters of approximately 30.2%~72.9%;However potassium was the same with phosphorus, but the proportion of redistribution of the leaves was relatively more, was 50.67% ~74.65%.(3) No-tillage corn acre yield 5.1% ~7.9% higher than ploughing. Whether ploughing or not, per corn strain NPK uptake and corn acre yield relationship was: covered with straw 9000kg/ hm2 covered with plastic filmcovered with straw 12000kg/hm2covered with straw 6 000 kg/hm2no cover. Compared with the conventional tillage farming, no-tillage was good for Guidan No.8 corn NPK uptake; no-tillage plastic cover and medium straw cover two modes of production was higher, was worth promoting in the production.
