- Abstract:
- The pomegranates of different ages at the soft-seeded pomegranate base in Heyin area of Henan Province were used as test materials.Using the methods of farmer households investigation and field experiment，the factors that restrict the popularization and application of soil testing and fertilizer application technology in Heyin area and the effect of soil testing and formula fertilization on the yield，quality and economic benefits of soft-seeded pomegranate were studied.The results showed that the yield of pomegranate in Heyin area was mainly concentrated at 15 000-30 000 kg·hm-2，and the yield of pomegranate was very signifcant difference among different farmers.The lowest yield was 7 500-15 000 kg·hm-2，and the highest was above 75 000 kg·hm-2.82.14% of the farmers are willing to use soil testing and fertilization technology for field demonstration test，including primary and high school education of farmers on the technical support rate of 100%，junior high school education minimum 66.7%.The results showed that the yield of soft-seeded pomegranate fruit increased significantly.The yield of different age soft-seeded pomegranate fruit increased by 59.4% (10 years)，34.1% (15 years) and 24.6% (20 years) respectively.The lower the age,the more significant the effect.The addition of potassium and magnesium fertilizer in the formula fertilizer could further enhance the yield of pomegranate，among which 10 years and 15 years old pomegranate increased by 14.4% and 15.7% respectively，while the 20-year-old pomegranate only increased by 4.7%.In addition to the yield，the formula fertilizer significantly improved the appearance of the different age of soft-seeded pomegranate phase，sugar and acid ratio and vitamin C content.Yield and quality of fruit to help farmers significantly improve the economic benefits，compared with farmers used to fertilizers，different age pomegranate application formula fertilizer after the average income increased by 67.21%，formula fertilizer+potassium and magnesium fertilizer average income increased by 93.42%，the younger the lower the effect of income more significant.On the whole，soil fertilization could improve the yield，quality and economic benefit of soft-seeded pomegranate，and the popularization and application of soil testing and fertilization techniques should be intensified in Heyin area.
