Effects Of Humic Acid,Fertilizer And Inorganic Fertilizer And Soil Conditioner On Yield And Quality Of Salvia Miltiorrhiza Continuous Cropping

To explore the different fertilizer（humic acid fertilizer and inorganic fertilizer,soil conditioner）on grain yield and quality of salvia miltiorrhiza continuous cropping,the influence of the test material by salvia miltiorrhiza,the completely random design,set up the CK,T1（humic acid fertilizer）,T2（defense wiener treasure）,T3（abamectin）,T4（soil conditioner）,T5（humic acid fertilizer line wiener treasure）,T6（humic acid fertilizer abamectin）,T7 has（humic acid fertilizer soil conditioner）,T8（humic acid fertilizer line wiener treasure soil conditioner）,T9（humic acid fertilizer abamectin soil conditioner）,a total of 10.The humic acid fertilizer and inorganic fertilizer and single or with the continuous cropping soil conditioner salvia miltiorrhiza field soil fertility,salvia miltiorrhiza morphological index,root knot nematodes and control effect,the influence of plant nutrient uptake,yield and quality,provide theoretical basis to alleviate continuous cropping obstacle.The main results are as follows:1.Humic acid fertilizer and inorganic fertilizer and soil conditioner on soil fertility.Humic acid fertilizer and inorganic fertilizer,and soil conditioner alone or with both can improve soil fertility and fertilization of processing in order to best humic acid fertilizer,each with treatment were greater than the single processing,with processing in order to best humic acid fertilizer line wiener treasure soil conditioner,humic acid fertilizer line wiener treasure soil conditioner are increased CK p H 10.93%improving soil micro environment,harvest when the soil organic matter,alkaline hydrolysis n,available p,available k content increased respectively than CK 37.40%、28.40%、26.12%、29.76%.2.Humic acid fertilizer and inorganic fertilizer and soil conditioner on the influence of salvia miltiorrhiza continuous cropping morphological characteristics.Humic acid fertilizer and inorganic fertilizer,and soil conditioner alone or with all can improve the salvia miltiorrhiza morphological characteristics,compared with CK,humic acid fertilizer line wiener treasure soil conditioner can effectively increase salvia miltiorrhiza taproot length 9.5 cm,the enlargement of salvia miltiorrhiza root diameter 3.1 mm,effectively increasing the number of points 3.7,increase the taproot length 6.3 cm.3.Humic acid fertilizer and inorganic fertilizer and soil conditioner on continuous cropping effect of salvia miltiorrhiza NPK accumulation.Various fertilizer treatments from different extent promoted the salvia miltiorrhiza plants on the absorption of n,p,k nutrients.salvia miltiorrhiza nitrogen,phosphorus and potassium accumulation in single processing,characterized by humic acid fertilizer>defence wiener treasure>soil conditioner>abamectin,each with processing salvia miltiorrhiza accumulation of nitrogen,phosphorus and potassium were significantly higher than the single processing,with processing salvia miltiorrhiza in the accumulation of nitrogen,phosphorus and potassium as humic acid fertilizer line wiener treasure soil conditioner>humic acid fertilizer abamectin soil conditioner>humic acid fertilizer line wiener treasure>humic acid fertilizer soil conditioner>humic acid fertilizer abamectin,so the humic acid fertilizer line wiener treasure most soil conditioner nitrogen,phosphorus and potassium nutrient accumulation.4.Humic acid fertilizer and inorganic fertilizer and soil conditioner influence on root knot nematodes index and control effect.Different fertilizer treatment can effectively reduce the incidence of salvia miltiorrhiza root.Compared with CK,the single processing,defense wiener treasure nematode control effect reached 31.54%.abamectin nematode control effect reached 26.45%.each with handling the nematode control effects were significantly higher than the single processing,with processing,humic acid fertilizer line wiener treasure nematode control effect reached36.19%.humic acid fertilizer abamectin nematode control effect reached 35.48%.humic acid fertilizer line wiener treasure soil conditioner processing root knot index lower,most nematode control effect is best 47.42%.5.Humic acid fertilizer and inorganic fertilizer and soil conditioner effect on yield and quality of salvia miltiorrhiza.Humic acid fertilizer and inorganic fertilizer,and soil conditioner alone or with all can improve the yield of salvia miltiorrhiza,single processing humic acid fertilizer yield the highest,reached 4016.89 kg/hm~2squared.Each with yield of salvia miltiorrhiza were greater than the single processing,with processing of humic acid fertilizer line wiener treasure soil conditioner yield the highest,higher than CK 132.17%,5752.65 kg/hm2 squared,and the processing conditions constitute the salvia miltiorrhiza production has a better correlation factor numerical,significantly increase the revenue.salvia miltiorrhiza or not is the effective composition content of fine quality high and low,humic acid fertilizer line wiener treasure soil conditioner processing of salvia miltiorrhiza tanshinone,Cain,tanshinoneⅠ,tanshinoneⅡA,Dan phenolic acid B effective composition content is significantly higher than other treatments,and conform to the standards set by the 2020 edition of"Chinese pharmacopoeia"content.To sum up,combined with salvia miltiorrhiza factors such as the yield and quality,this study humic acid fertilizer line wiener treasure soil conditioner most conducive to salvia miltiorrhiza to reduce continuous cropping obstacles,achieve maximum economic benefits.
