Abstract:

In order to further clarify the wheat production situation in the central area of Jiangsu Province, the survey data about wheat production of rural households were obtained by questionnaires in Xinghua and Gaoyou from 2016 to 2020. The survey showed that the main workforce of farmers in wheat production were between the age of 51 and 60 with junior high school education level. This group urgently needed new agricultural technologies, but their acceptance ability was relatively low. There were significant differences in wheat sowing date, sowing rate and fertilizer application rate taken by different farmers. The farmers were more likely to obtain high yield when wheat was planted from October 26th to November 5th with the sowing rate of 211-240 kg/hm2. The average nitrogen application rate taken by farmers was 308 kg/hm2 and 281 kg/hm2 in Xinghua and Gaoyou, respectively. The wheat yield decreased when nitrogen application rate was higher than 350 kg/hm2. Under the combination of sowing date, sowing rate and nitrogen application rate, the average yield of wheat in Xinghua and Gaoyou was 6129.64 kg/hm2 and 6788.25 kg/hm2, respectively. The yield gap between high and low yield was 2270.36 kg/hm2 in Xinghua and 1611.75 kg/hm2 in Gaoyou, respectively. The economic benefits of different wheat planting scales were different. When the planting area was 6.67-20 hm2, most farmers could get relatively high benefits, only a few farmers had economic loss. When the planting scale was more than 33.33 hm2, the proportion of farmers with loss was relatively high, and farmer with benefits had low per unit area reward in wheat planting. In conclusion, farmers with 20 hm2 wheat planting scale can obtain higher yield and benefits when the sowing date is from October 26th to November 15th, the sowing rate is 200-240 kg/hm2 and nitrogen application rate is 250-300 kg/hm2,the scheme can be promoted in the central area of Jiangsu Province.
