Effects of Sowing Time, Density and Fertilizer Application on the Economic Characters of Zhuoyou 058

In order to study the high-yield cultivation techniques of Zhuoyou 058,the single-factor test design method was applied to study the effects of sowing time,density,and fertilizer application on plant traits,yield traits and yield.The results showed that with the delay of sowing,the plant height and the first branch height decreased,the whole growth period was shortened,and the yield was the highest at 197.50 kg/666.7 m^2 in the treatment of sowing on October 1,so the most suitable sowing date should be before October 9.With the increase of the planting density,the plant height and the first branch height increased,the yield traits decreased significantly,and lodging occurred.The yield per unit area was the highest at 201.44 kg/666.7 m^2 under the density of 12 000 plants/666.7 m^2,and the lowest at 155.47 kg/666.7 m^2 under the density of 6 000 plants/666.7 m^2.Therefore,the best density was 9 000-15 000 plants/666.7 m^2.As the fertilizing amount increased,the plant height,the first branch height,the number of effective branches and the number of effect pods all increased,and the yield was the highest at 194.93 kg/666.7 m^2 under the fertilizing amount of 50 kg/666.7 m^2,and the lowest at 135.16 kg/666.7 m^2 under the fertilizing amount of 30 kg/666.7 m^2.The gross profit was the highest at 854.20 yuan/666.7 m^2 under the density of 12 000 plants/666.7 m^2,and the second highest at 836.65 yuan/666.7 m^2 under the fertilizing amount of 50 kg/666.7 m^2.The best fertilizing amount should be 40-50 kg/666.7 m^2 in cultivation.
