为解决水稻平作栽培与蚯蚓无法共存的难题,本研究提出一种水稻垄作栽培养殖蚯蚓的技术模式,并探究了水稻垄作栽培与养殖蚯蚓结合对水稻生长特性及产量的影响,通过设计常规水稻垄作栽培(CK) 、水稻垄作放养蚯蚓20 g·m~(-2)(RE1) 、40 g·m~(-2)(RE2)和60 g·m~(-2)(RE3)的田间对比试验,研究水稻垄作养殖稻蚯蚓模式下植株地上部生长特性、根系生长特性和产量及产量构成。结果表明:与CK处理相比,RE3、RE2和RE1处理水稻地上部干物质积累量在孕穗期至成熟期增幅分别为10.81%~ 13.70%、9.14%~ 12.44%和7.23%~ 8.82%,叶面积指数增幅分别为8.39% ~ 14.40%、6.33% ~ 10.94%和7.02% ~ 10.34%;水稻垄作养殖...

To solve the failure of coexistence between rice and earthworm in conventional flat planting,we proposed an earthworm raising technique under rice ridge cultivation and explored its effects on rice growth and grain yield. A field experiment was conducted with the treatments of conventional rice ridge cultivation (CK),rice ridge planting with earthworm raising at a density of 20 g·m~(-2)(RE1),40 g·m~(-2)(RE2) and 60 g·m~(-2)(RE3) . The growth properties of shoots and roots of the plants,grain yield,and the formation of yield were investigated...
