Abstract

To study the effects of mulching on fine roots and fruits of Camellia oleifera Abel, four materials (Peanut stalk + straw, black mulch, eco-film, C. oleifera shell) were used to mulch on the C. oleifera forest land. The nondestructive minirhizotrons were used to in-situ monitor the growth, death, and turnover of fine roots for one year, and the fruit properties were measured for three years. The results showed that the annual productions of fine roots by black much and peanut stalk + straw were broadly improved in 10-30 cm soil layer. Compared with CK, the annual death of fine roots of all mulching treatments increased in 30-40 cm soil layer. It was found that mulch with peanut stalk + straw promoted the turnover of fine roots by increasing annual production in the soil depth of 10-30 cm. The comprehensive ordering of fruit yield and properties was: peanut stalk + straw treatment > black mulch > C. oleifera shell > CK > eco-film. Overall, the peanut stalk + straw was the best treatment to enhance the yield and properties of fruits via fine roots promotion.

地膜下的细根促进可提高油茶的果实产量和特性

摘要

为了研究覆盖对细根和果实的效果油茶阿贝尔,四种材料(花生秆+稻草,黑色覆盖,生态膜,油茶壳)被用来覆盖在油茶林地。非破坏性微型根瘤菌用于原位监测细根的生长,死亡和周转,为期一年,并且对果实的性状进行了三年的测量。结果表明,在10-30 cm的土壤层中,黑多和花生秸秆+秸秆的细根年产量有了较大提高。与CK相比,在30-40 cm的土壤层中,所有覆盖处理的细根每年死亡均增加。研究发现,通过在秸秆覆盖层上覆盖花生秸秆和秸秆,可以增加土壤深度(10-30厘米)的年产量,从而促进细根的周转。水果产量和特性的综合排序为:花生秸秆+秸秆处理>黑覆盖>油茶外壳> CK>生态膜。总体而言,花生秸秆+秸秆是最好的处理方法,可通过促进细根来提高果实的产量和特性。
