摘要
2:009年在湖南省祁阳县板页岩发育的高岸田和低垄田开展了湘南丘岗区水稻抗逆稳产轻简技术集成研究与示范试验,结果表明:(1)湘南板页岩丘岗区的排田和垄(冲)田,在施用等量N、P、K养分条件下,早晚稻稻谷、稻草的产量均以水稻专用肥为最高;(2)无论是排田还是垄田,施用水稻专用肥,都有利于水稻的生长发育,水稻有效穗多,结实率高,千粒重增加;(3)湘南板页岩丘岗区的排田和垄(冲)田,一次性施用水稻专用肥("湘珠牌"水稻专用肥),能够增加排田、垄田早稻稻谷和垄田晚稻稻谷、稻草的吸氮、吸磷、吸钾总量,对晚稻而言,垄田一次性施用水稻专用肥后,其稻谷、稻草吸收养分总量的优势比排田要明显。
The researches and demonstrate experiments about simple and labor saving techniques for stress resistance and stable production of rice in hilly-area of southern Hunan were conducted in the high-bank field and low-ribbing field,which developed from plate shale,in Qiyang County,Hunan Province in 2009.The results showed that：（1） The row field and ridge field in hilly-area of southern Hunan,under the same fertilizer rate of N,P,K,the highest yield of rough rice and straw of early rice and late rice were in the application of specialty fertilizer for rice.（2） No matter for row field or ridge field,to apply specialty fertilizer for rice can benefit for the growth of rice,and will obtain more effective panicle,high setting percentage,and increasing kernel weight.（3） For the row field and ridge field in hilly-area of southern Hunan,applying the specialty fertilizer for rice（Xiangzhu specialty fertilizer for rice） at one time can increase the total N,P,K absorption amount of rough rice of early rice in row field and ridge filed and rough rice and straw of late rice in ridge field,in which the total nutrition absorption amount of rough rice and straw of late rice in ridge field had more obvious advantages than that in row field.
