Effects Of Different Ring Groove High Disk Treatment On Longon Trees And Soil

This experiment used clean tillage as a control, set the following treatment: (1) high disk ring groove earthworms; (2) high disk ring groove albuginea; (3) high disk ring groove black film; (4) high disk ring groove filmless. Study on different high disk ring ditch soil management on soil, longan roots, longan trees and longan fruit. The following conclusions:1, high disk ring groove albuginea, high disk ring groove black film treatment of the soil daily average summer temperature exceeds the optimum root growth temperature of longan; high disk ring groove ring groove processing can gather precipitation, significantly increased soil moisture.2, High disk ring groove earthworms, high disk ring groove albuginea, high disk ring groove black film can improve soil pH, organic matter content, total nitrogen, total phosphorus, total potassium content, high disk ring groove can raise soil pH, organic matter, total nitrogen, total phosphorus, total potassium content.3, high disk ring groove earthworms, high disk ring groove albuginea, high disk ring groove black film can significantly promote the growth of longan roots; vermicompost in ring ditch can increase the number and weight of roots.4, high disk ring groove earthworms, high disk ring groove albuginea, high disk ring groove black film, high disk storage ring groove can improve longan water potential of twigs, relative water content, SPAD values of leaf, leaf area, leaf total nitrogen, total phosphorus, total potassium content.5, high disk ring groove earthworms, high disk ring groove albuginea, high disk ring groove black film can reduce fruit cracking rate, improve longan production,panicle weight,fruit weight, increase the edible rate, soluble solids, soluble sugar, Vc content; high disk ring groove can improve longan fruit edible rate, total sugar, Vc content.After a comprehensive analysis of the effects of different high disk ring groove on mature longan orchards,we found high disk ring groove earthworms, high disk ring groove albuginea, high disk ring groove black film to improve soil moisture, heat conditions, nutrients, improve tree nutrients, fruit yield and quality,and other aspects have a significant effect. High disk ring groove earthworm as a new model of breeding earthworms in orchard, to improve the soil and trees nutritional of the best, it also in line with the sustainable development of China’s strategic thinking.
