以'布兰瑞克'无花果果树为试验材料,采用地下穴贮灌溉装置对无花果根际土壤通气,设置加气施磷肥(OP)、加气不施磷肥(OF)、不加气施磷肥(NP)、不加气不施磷肥(NF)4个处理,研究其对南疆设施无花果植株的生长情况及土壤磷吸收转化的影响,以期为地下穴贮滴灌注气技术在设施无花果中的应用提供参考依据.结果表明:OP、OF、NP在不同程度上均可以促进无花果植株生长,增加各土层土壤的含水量及调节土壤pH.其中OP在30～80 d、OF在50～80 d均显著促进无花果的新梢生长;在0～20 cm 土层中,OP、OF、NP的土壤含水量较NF分别降低15.02％、9.84％、1.98％;OP较NF处理能够显著提高各土层的土壤酸性磷酸酶活性,其中对0～20 cm 土层提升效果最佳,提高了157.37％;OP处理的土壤速效磷含量在0～20、20～40、40～60 cm的3个土层中分别提高了212.82％、160.79％、98.77％.综上,加气处理对'布兰瑞克'无花果植株的生长及土壤全磷转换为速效磷等均有促进作用.
Effects of Aeration on the Growth of Figs and the Uptake and Transformation of Soil Phosphorus in Southern Xinjiang Facilities
Taking'Braunschweig'fig plants as the test materials,four treatments were set up,aerated phosphorus fertilizer(OP),aerated without phosphorus fertilizer(OF),phosphate fertilizer without aerated fertilizer(NP),and without phosphate fertilizer without aerated fertilizer(NF),effects of aeration on the growth of figs and the uptake and transformation of soil phosphorus in Southern Xinjiang facilities were studied,in order to provide reference for the application of drip gas storage and gas injection technology in the facility figs.The results showed that OP,OF and NP could promote the growth of fig plants,increase the soil water content and adjust the soil pH value of each soil layer to different extents.Among them,OP at 30-80 days and OF at 50-80 days significantly promoted the growth of new shoots of figs.In the 0-20 cm soil layer,the soil moisture content of OP,OF and NP decreased by 15.02％,9.84％and 1.98％,respectively,compared with NF.Compared with NF treatment,OP treatment could significantly increase the soil acid phosphatase activity in each soil layer,and the soil acid phosphatase activity of 0-20 cm soil layer was the best,which increased by 157.37％,and the soil available phosphorus content of OP Treatment increased by 212.82％,160.79％and 98.77％in the three soil layers of 0-20 cm,20-40 cm and 40-60 cm,respectively.In conclusion,the aerated treatment had a promoting effect on the growth of'Braunschweig'fig plants and the conversion of soil total phosphorus to available phosphorus.
