柑桔是浙江省的主要水果品种。全省1990年共有桔园1.22×10~5 hm~2,柑桔产量达7.973×10~5 t,占全省水果总产量的74.51%。随着农村经济改革的深入,柑桔种植面积仍在不断扩大,并向红壤丘陵地区发展。但是,由于低丘红壤的肥力条件差,单一开发种植柑桔产量不高,且易导致水土流失等土壤生态问题。本研究选择新垦植的幼龄桔园进行冬季牧草间作试验,研究其对土壤温度、水土流失、土壤肥力以及幼桔树生长的影响,旨在为提高幼龄桔园间作的生态经济效益提供科学依据。 Citrus is the main fruit variety in Zhejiang Province. In 1990, the province had a total of 1.22 × 10 ~ 5 hm ~ 2 citrus orchards and citrus yield of 7.973 × 10 ~ 5 t, accounting for 74.51% of the total fruit output in the province. With the deepening of rural economic reform, citrus cultivation area is still expanding, and to red soil hilly areas. However, due to the poor fertility conditions in the low hillside red soils, the output of monoculture development of citrus is not high, and soil ecological problems such as soil erosion are easily caused. In this study, we selected young reclaimed young orange orchards for winter intercropping experiments to study their effects on soil temperature, water and soil loss, soil fertility and the growth of young orange trees in order to provide the ecological and economic benefits of young orange orchard intercropping Scientific basis.
