Effects of different dosages of soil conditioner on the growth of Puccinellia tenuiflora and soil nutrients
In order to clarify the effects of different dosages of soil conditioner on the growth and development of Puccinellia tenuiflora and soil nutrients,a field experiment was conducted to analyze the effects of different dosage of soil conditioner on yield,nutritional quality,soil nutrients and water content of Puccinellia tenuiflora.The results showed that the application of soil conditioner significantly increased the yield of Puccinellia tenuiflora.When the application dosage of soil conditioner reached 30 t·hm-2,the yield of Puccinellia tenuiflora reached the maximum.The soil nutrient content increased with the increase of the application dosage of soil conditioner,and reached the highest when the application dosage of soil conditioner was 30 t·hm-2.The nutritional quality of Puccinellia tenuiflora varied with the increase of soil conditioner application dosage.The content of neutral detergent fiber and acid detergent fiber decreased with the increase of soil conditioner application dosage,and the content was the lowest when the soil conditioner application dosage was 30 t·hm-2.The content of crude fat,crude protein,starch,calcium,magnesium,iron and zinc reached the highest when the soil conditioner application dosage was 30 t·hm-2.Soil conditioner significantly affected the water conservation capacity of soil.Compared with the control,the soil moisture content of 15 and 30 t·hm-2 soil conditioner increased by 5.15 and 9.10 percentage points,respectively.In summary,when the application dosage of soil conditioner was 30 t·hm-2,the soil nutrient content and the growth of Puccinellia tenuiflora were the best.
