根据丘陵地区的土壤、气候生态特点和水稻品种的适应性,岗、塝、冲田层次品种布局,分别以常规中籼、杂交中籼和中粳类型品种为主体,岗田搭配早熟杂交中籼,冲田搭配中、晚熟杂交中籼,以达到自然资源和品种优势的最佳组合.高产栽培的技术途径,岗田以增大穗型,塝田以提高结实率,冲田以争取足穗为主.穗肥比例,常规中籼、杂交中籼和中粳稻分别为15%、20%、25～30%;水浆管理,岗田以蓄为主,冲田以排为主,塝田蓄排结合.
According to the characteristics of soil, climatic and ecological characteristics and adaptability of rice varieties in hilly areas, the main types of middle-aged and mid-season indica hybrid rice varieties were middle-aged and middle-aged rice cultivars. Okinawa with middle and late maturing medium indica rice, in order to achieve the best combination of natural resources and variety advantages.High-yielding cultivation techniques, Kong Tian to increase the panicle, Gao field to improve the seed setting rate, Okada in order to fight the foot-based. The ratio of panicle to panicle was 15%, 20% and 25 ~ 30% for conventional medium and medium indica, medium and medium japonica hybrid rice respectively.
