摘要:

本研究在浙江北部典型滨海盐碱化耕地中设置田间小区试验,以鲜食毛豆和西蓝花周年轮作系统为对象,分析不同有机物料(KW:厨余堆肥;MR:菌渣有机肥;OBF:生物炭+有机肥;MBF:生物炭基肥)和施入深度(D:深施,旋耕30 cm翻入肥料;M:浅施,旋耕20 cm翻入肥料;S:表施,土层表面施肥)对土壤性质和作物生长的影响。结果表明,施入不同有机物料均能促进毛豆和西蓝花的生长,D-OBF、D-MBF、M-OBF、M-MBF等4个处理下鲜食毛豆和西蓝花的产量均较高,鲜食毛豆产量达10.0~10.8 t·hm-2,比CK增产31.6%~42.1%,西蓝花产量16.0~16.7 t·hm-2,比CK增产27.0%~32.5%,周年增产效益达5 534~8 164元·hm-2;深施和浅施处理耕层的土壤电导率均大幅下降,其中深施对全耕层土壤有机质含量的提升作用显著,D-MBF和D-OBF处理耕层上部(0~15 cm)的有机质含量分别比CK增加1.7~2.2 g·kg-1、耕层下部(16~30 cm)分别增加0.9~1.4 g·kg-1。因此,利用生物炭配施有机肥或生物炭基肥配合适度深耕施入对滨海盐碱化土壤培肥改良效果较好,该技术在我国滨海中低产田具有较大的推广应用潜力。

Abstract:

A field experiment was carried out in a typical coastal saline-alkali cultivated soil in northern Zhejiang Province, with the annual rotation system of vegetable soybean and broccoli as the research object. The effects of different organic materials (KW: kitchen waste, MR: mushroom residue, OBF: biochar+organic fertilizer, MBF: biochar-based fertilizer) and application depth(D: Deep application, with fertilizer incorporated by rotary tillage to a depth of 30 cm; M: Shallow application, with fertilizer incorporated by rotary tillage to a depth of 20 cm; S: Surface application, with fertilizer applied to the surface of the soil layer)on soil properties and crop growth were analyzed. Our results showed that application of different organic materials could promote the growth of vegetable soybean and broccoli. Under the four treatments (D-OBF, D-MBF, M-OBF, and M-MBF), the yields of vegetable soybean and broccoli were all higher. The edamame yield reached 10.0-10.8 t·hm-2, representing a 31.6%-42.1% increase over the CK, while the broccoli yield was 16.0-16.7 t·hm-2, showing a 27.0%-32.5% increase compared to CK, and the annual economic benefit was 5 534-8 164 yuan·hm-2. Deep and shallow application treatment significantly decreased the soil EC, while deep application significantly increased the soil organic matter content in the entire topsoil layer. The organic matter content in the top surface layer (0-15 cm) under D-MBF and D-OBF treatment increased 1.7-2.2 g·kg-1and 0.9-1.4 g·kg-1in the lower surface layer (16-30 cm), respectively, compared with CK. Therefore, the application of biochar combined with organic fertilizer or biochar-based fertilizer combined with moderate deep ploughing has a good effect on the improvement of coastal saline-alkali soil, and this technology has a great potential for application in China’s coastal middle and low yield fields.
