Abstract:
‘Sanying No.8’pepper was as material，through two field experiments,four types and proportions of phosphate fertilizer were set up,including diammonium phosphate (DPA),calcium magnesium phosphate (CMP),50% diammonium phosphate+50% calcium magnesium phosphate (DPA/CMP),modified calcium magnesium phosphate (MCMP).The effects of different types and proportions of phosphate fertilizer on the growth characteristics,dry matter accumulation,phosphorus absorption and yield of pepper were analyzed.The plant height and branch number of pepper were affected by the type of phosphate fertilizer.The plant height of DPA treatment was always high,and that of CMP treatment was low,especially in the young fruit stage and flowering fruit stage.The branch number of DPA/CMP and MCMP treatment was significantly higher than that of CMP and DPA).The biomass of pepper plants in mature stage was fruit>stem>leaf,and the stem biomass of modified calcium magnesium phosphate (MCMP) treatment was significantly higher than that of other treatments；from the perspective of yield (fruit),the yield of pepper with modified calcium magnesium phosphate (MCMP) was the highest,followed by calcium magnesium phosphate (CMP) and calcium magnesium phosphate plus diammonium phosphate (DPA/CMP),and diammonium phosphate (DPA) was significantly lower and the lowest.The application of modified calcium magnesium phosphate (MCMP) promoted the accumulation of phosphorus in pepper stems and leaves；in fruits,the accumulation of phosphorus in MCMP was significantly higher than that in CMP and DPA/CMP,and DPA was the lowest.Under the condition of this experiment,the plant height was decreased and branch number of capsicum was increased and the dry matter and accumulation of pepper stem and leaf were increased,the phosphorus absorption of capsicum was promoted and the yield of capsicum fruit was increased.
