摘要
为筛选合适的施肥方案,以甬优1540品种为例,分析在绿色食品标准之下,不同的施肥方案对水稻产量、品质以及病虫害发生的影响.结果表明,未经过施肥处理的稻田产量最低,在每亩施用纯N 7.5 kg、P2O5 2.8 kg、K2O 8.0 kg的基础上加施 20 kg海藻肥处理的水稻产量最高,且品质好、病虫害发生少,可作为江浙地区绿色食品水稻生产的推荐用肥.
Abstract
In order to identify the optimal condition for fertilizer application,the effects of different fertilizer application on yield and quality of rice and the occurrence of pests and diseases under the green food standard were analyzed in the present study.The Yongyou 1540 variety was used.The results showed that the lowest yield was found in the unfertilized rice field,and the highest yield was found in the rice treated with 0.03 kg·m-2 of seaweed fertilizer,45.53 kg of pure N,17.00 kg of P2O5,and 48.57 kg of K2O per acre.This condition resulted in better quality,fewer pests and diseases.This condition is recommended for the use of fertilizer in green food rice production in nearby regions.
