为研究‘广两优676’超高产水稻作为菜后稻的施肥效应,应用“3414”试验设计方法,在菜田上进行田间试验。结果表明,在碱解氮含量偏低、有效磷钾含量丰富的菜田上,施用氮肥具有显著增产效果,磷钾肥具有一定增产作用。根据建立的三元二次肥效模型,得到试验条件下的经济施肥量为 N 103 kg·hm-2、P2 O541 kg·hm-2、K2 O 103 kg·hm-2,氮磷钾适宜施用比例为1∶0.4∶1。
為研究‘廣兩優676’超高產水稻作為菜後稻的施肥效應,應用“3414”試驗設計方法,在菜田上進行田間試驗。結果錶明,在堿解氮含量偏低、有效燐鉀含量豐富的菜田上,施用氮肥具有顯著增產效果,燐鉀肥具有一定增產作用。根據建立的三元二次肥效模型,得到試驗條件下的經濟施肥量為 N 103 kg·hm-2、P2 O541 kg·hm-2、K2 O 103 kg·hm-2,氮燐鉀適宜施用比例為1∶0.4∶1。

We carried out the research on the NPK fertilizer response of the super high-yielding rice variety‘Guangliangyou 676’grown on vegetable field with ‘3414’the optimum regression design.The results indicated that N application could significantly increase the yield of rice in the lower alkali-hydrolyzable nitrogen,but rich available phosphorus and potassium in the vegetable field.P,K application could improve it to some degree. According to the imitative results of regression equation,the economic application rates of N,P2 O5 and K2 O were 103 kg·hm-2 ,41 kg·hm-2 and 103 kg·hm-2 ,respectively.The proper ratio of N∶P2 O5 ∶K2 O was 1 ∶0.4∶1 in the vegetable field.
