Study on Planting System and Complete Set of High Yield Technical Measures of Corn

More than 3 years experiments in multiple plot and demostrative popularization on a large scale show that hybrid corn can be planted in Fujian in Spring, Summer and Autumn; the best planting method for 15 percent increase in yield and value by compound colony of main crops as soybeans, peanut and sweet potato and intercrops as corn is: main crop keeping planting areas and optimum density, intercrop corn in furrow drilling 1400 plant/mu; high yield technical measures for single cropping of more than 350 kg in Autumn sowing; sown between July 25 to August 5, basic seedlings per mu 5000- 5500, fertilizing nitrogen 10-12 kg-on an average of top application of jointing and spike fertilizer.
