Abstract:

To study the effects of bio-organic fertilizers on the yield of fresh corn, soil nutrients and microbe quantity, fresh corn 'Zhongke nuotian 99' was used as material, the agronomic traits and yield were investigated by field experiment, and the nutrient content and microbe quantity of soil were detected. The results showed that soil pH was significantly decreased by 4.9%-6.8% compared with the control, along with the application of bio-organic fertilizer. The soil nutrients were increased obviously, and the contents of organic matter, alkaline nitrogen, available P and available K were increased by 5.4%-9.8%, 4.9%-11.6%, 6.7%-19.2% and 4.9%-19.4% respectively. The number of soil microbes was also increased. The corn height, ear length, ear diameter, ear row number, single ear weight, kernel number per row and 100-seed weight were increased with the application of bio-organic fertilizer, and the yield were also increased by 8.5%-16.5% compared with the control. Bio-organic fertilizer not only increases the soil nutrients, the quantity of microbes and soil fertility, but also promotes the growth and yield of fresh corn.
