不同施肥配方对草莓脱毒苗繁育量及经济效益的影响

摘要

In order to provide theoretical basis for fertilization techniques of detoxicated strawberry seedlings in Yuxi area, "3414"soil protocol was designed to compare the yield for different detoxicated strawberry seeding population under different ratio of nitrogen, phosphorus and potassium, and select the best ratio for nitrogen, phosphorus and potassium for the optimal yield.The results showed that N fertilizer had the greatest impacts on the yield of detoxicated strawberry seedling, followed with P fertilizer, while K fertilizer showed the poorest impacts.Detoxicated strawberry seedling was at the maximum economic yield and benefits when fertilizer N was 12 kg/667 m2, P2O5 was 10 kg/667 m2 and K2 O was 10 kg/667 m2.At the same time, yield, output value and net income were respectively 103 712 plant/667 m2, 41 484.80 Yuan/667 m2 and 41 324.16 Yuan/667 m2.%为了给玉溪地区草莓脱毒种苗繁育施肥提供理论依据, 采用3414测土配方试验设计, 通过不同的氮磷钾配比了解草莓的生育变化并进行其产量比较, 从中筛选出合理的氮磷钾配比, 并得出最佳繁育量.结果表明:氮肥对草莓脱毒种苗繁育量的影响最大, 磷肥其次, 钾肥最小;当氮磷钾配施为N 12kg/667m2、P2O5 10kg/667m2和K2O 10kg/667m2能获得最高的经济产量和效益, 繁育量、产值和产出分别为103 712株/667m2、41 484.80元/667m2、41 324.16元/667m2.
