摘要
在浙江省马铃薯主产区以马铃薯克851为材料,通过二年连续试验研究了马铃薯施肥措施对产量及相关性状的影响。试验表明,在当地习惯施肥(N-80kg/hm2、农家肥-104kg/hm2)基础上,提高氮肥量至120kg/hm2,同时增施磷钾肥,提高了马铃薯产量、块茎淀粉含量和商品率,提高了叶绿素含量和净同化率。同时,试验表明增施磷钾肥的不同处理增产提质效果不同。根据实际生产效益,推荐施肥量为:N-120kg/hm2、P2O-80kg/hm2、K2O-180kg/hm2、农家肥-104kg/hm2。
After taking Ke-851 potato as the experiment object for two years in the main potato producing area of Zhejiang province, experts try to research on the effects of the production and related traits by applying different fertilizing measures. The result of the tests indicates that the starch content and the commodity rate are improved by increasing the amount of nitrogenous fertilizer to 120kg/hm^2 on the basis of local normal fertilizers, such as N-80 kg/hm^2 and farmyard manure 10^4kg/hm^2. Besides, the leaf area index, chlorophyll content and net assimilation rate will rise too. But the increased production amounts differ each other by applying different fertilization measures. According to practical producing rates, the author recommends following fertilizing amounts： N-120 kg/hm^2, P2O5-80 kg/hm^2, K2O-180kg/hm^2 and farmyard manure 10^4kg/hm^2.
