稻虾种养模式下水稻品种筛选及关键栽培技术

稻田养虾是一种绿色、生态、高效的农业种养模式。为筛选出适合海盐地区不同稻虾种养模式种植的优质水稻品种,对不同水稻品种在稻虾种养模式下的产量及生育期表现进行了比较。结果表明,稻虾连作模式适宜选用优质高产常规稻嘉67、嘉禾236等;稻虾套养模式则适宜选用生长旺盛的籼粳杂交稻嘉优中科13-1;繁养一体模式适宜选用熟期较早、产量稳定的常规稻南粳3908、天微香粳等。针对稻虾种养模式的特点,提出了适宜的水稻栽培方式、种植密度、肥水管理等关键技术。

Screening of Rice Varieties and Key Cultivation Techniques under Rice-crayfish Farming Model

Rice-shrimp farming model is a green, ecological and efficient agricultural farming model. In order to screen out rice varieties suitable for different rice-shrimp farming model, the yield and growth period performance of different rice varieties under rice-shrimp farming model were compared. The results showed that, the high-quality and high-yielding conventional rice such as Jia 67 and Jiahe 236 is suitable for the continuous cropping model of rice and shrimp; the vigorous indica-japonica hybrid rice varieties such as Jiayou Zhongke 13-1 is suitable for the rice-shrimp intercropping model; the early maturity and stable-yield conventional varieties such as Nangeng 3908 and Tianweixianggeng is suitable for the integrated breeding model. According to the characteristics of rice-crayfish farming model, the key techniques such as rice cultivation methods, planting density, fertilizer and water management were put forward.
