Effects of Intercropping Stropharia Rugoso-annulata on Tea Garden Soil and Tea Growth

Taking 1year old young tea plantation in hilly region of red soil of Fujian as a case study, discussed the influences of soil environment of tea plantation and germination period and yield of spring tea compared with intercropping Stropharia Rugoso-annulata in open ground in tea field in 4-year continuous winter.The results indicated that intercropping and recycling fungi residue as fertilizer can lower down the bulk density and increase OM, pH, total N, hydrolysis N and available P of soil, and the effect of keeping water and temperature for soil was obvious in wintering period which was less rainy and lower temperature of Fujian region.The soil moisture raised up to 9.22%, 6.11%in 0-20cm, 20-40cm soil layers respectively during the period of October to February of the next year.The soil average temperature raised up to 0.90℃, 0.77℃, 0.67℃, 0.50℃in 5cm, 10cm, 15cm, 20cm soil layers respectively during the period of December to February of the next year.Intercropping also can ensure the safety of young tea tree in winter.Compared with clearing tillage tea plantation, intercropping Stropharia Rugosoannulata had obvious advantages:4.3days earlier in germination period, 11.1% more in yield production.
