The Effect Of Different Fertilization Amount On The Organ Nutrition And Yield Of Fenzhi No.2

Shanxi has a planting area of 150,000 mu to 200,000 mu per year.In recent years,with the changes in the corn market,the industrial structure has been adjusted and the area has expanded.It is planted in the south of Chenzhou,Shanxi Province(including Zhangzhou).The sesame has the characteristics of short growth period and dense planting.Pingchuan Mountain is suitable,especially under the mountain forest.It can be used as one of the best choices for the interplanting of the Lvliang Mountain.Sesame in Shanxi Province is mainly distributed in Yuncheng,Wenxi,Jinzhong and Luliang in Jinnan.For a long time,how to properly fertilize and find a suitable compound fertilizer has become the primary problem that plagues farmers,and has become an important research content for sesame production.At present,there is no research on the dry matter accumulation of N,P and K fertilizers in sesame plants in China,and all the papers that can be found on other oil crops can be found.The purpose of this experiment is to investigate the accumulation and variation of nitrogen,phosphorus and potassium in different stages of sesame development,and find the fertilizer ratio of nitrogen,phosphorus and potassium which is most suitable for sesame growth,and provide scientific guidance for sesame production..The material selected for this experiment was Zhizhi No.2,and three fertilization treatment groups and one control group were established.Each fertilization treatment fertilizer is applied as a base fertilizer.Each treatment was repeated three times in a random manner.Through sampling,statistics and analysis of the growth stages of sesame seeds under different fertilization treatments,the results showed that the sesame plant height was affected by fertilization,but the higher the planting rate,the higher the plant height.Fertilization treatment significantly improved the area of sesame leaves and the dry matter of the plants,and had no significant effect on the number of sesame leaves.With the increase of fertilizer application rate,the nitrogen content in sesame stems and leaves also increased,but the phosphorus content did not increase.The more phosphorus fertilizer application,the higher the yield performance,but the phosphorus application rate was too high.After that,the yield will decrease;the potassium content of stems and leaves with high phosphorus application rate is higher,but the difference of potassium content in leaves is not significant.Fertilization can increase the yield of sesame,and the yield is significantly improved compared with the treatment without fertilizer.The results show that the higher the amount of fertilizer applied,the higher the yield.Reasonable fertilization is required in the production of sesame.In this test,the yield oftreatment 1 is the highest.The most reasonable amount of NPK is 150 kg of pure nitrogen per hectare,90 kg of phosphorus pentoxide and 45 kg of potassium oxide.
