Abstract:

The aim of this experiment is to study the technology with applying high quality and fertilizer on summer maize. The study was used ‘Zhengdan 958’ as the experimental material. On the basis of this typical plant, it had shown several influences, such as yield of summer maize, single plant leaf area, single plant leaves number, plant height, leaf area index and ear traits that was affected by these three kinds of methodologies on different fertilizers. The results revealed that the processing No.1 (the seeding fertilization 10% + the ears fertilization 60% + the grain fertilization 30%). It had improved the treatment on the leaf area of plants, leaf area index, plant height, and green leaves number of corn plant significantly. Then, it also increased the number of corn green leaves. Moreover, the individual grains of dry matter accumulation and grain weight had been promoted as meanwhile. Therefore, the production of maize had increased finally. Compared with the processing No.2 (the seeding fertilization 10% + the ears fertilization 90%), results had achieved on increasing yield at 1155.66 kg/hm2 and the increasing rate of 11.65%. At the same time, the comparison with the processing No.3 (the all total fertilization 100% with ears fertilization) results could be reached at the level of increasing yield at 1770.84 kg/hm2, and increasing yield rate of 19.03% respectively. While, from the comparison between Processing No.2 and No.3, we might find that the result of former sample had got the increasing production at 615.18 kg/hm2 and increasing rate of 6.61%. In order to obtain the effect on the high-yield of summer maize and promoting the effect of normal nitrogenous fertilizer, this study was adopted the method of three times fertilization. Consequently, it had shown that the increasing production of summer maize with high-efficiency obviously.
