- 摘要:
- 以邢台县“红富士”苹果园为研究对象,通过对当地果园的养分投入类型和投入量、灌溉方式和灌溉量以及产量进行调研,评价其水肥投入水平,并基于Boundary line分析法,探索该地区苹果园最高产量下的最佳养分施用量,以期明确邢台县苹果园水肥投入现状及最高产量水平下最佳养分投入量。结果表明:邢台县苹果园无机肥投入量较高,有机肥投入不足,无机肥N、P2O5、K2O平均投入量分别为825、460、692 kg·hm-2,有机肥仅为177、138、100 kg·hm-2;有机肥施用率较低,仅占调查总数的2735%,且施用种类繁多,鸡粪、羊粪及商品有机肥三者总计占比达9561%。灌溉方式以漫灌、沟灌为主,二者合计占比达9370%,滴灌仅为630%;生长季内灌溉次数多为3~4次;与滴灌相比,漫灌和沟灌单次灌水量分别多用140%、100%。Boundary line模型分析显示,邢台县苹果园最高产量水平下N、P2O5、K2O投入量分别为61650、37190、55310 kg·hm-2,对产量的贡献分别为2800%、1760%、2260%。总之,邢台县苹果园养分投入量较高,轻有机重无机,肥料投入种类繁多,漫灌和沟灌为其主要灌溉方式,水资源浪费严重。
- Abstract:
- In order to make it clear that how about the contributed level of the water and fertilizer is,and how about the best dosage of nutrient is under the highest yield of apple.The apple orchards of Xingtai county was regarded as the research object,and evaluating its level of the input of water and fertilizer by the investigate about the form and dosage of nutrient,the mode and dosage of irrigation,besides exploring the best dosage of nutrient under the highest yield based on the mode of boundary line.The result showed that,the dosage of inorganic fertilizer was high,but the organic fertilizer was short,the average of dosage of inorganic fertilizer N,P2O5,K2O were 825 kg·hm-2,460 kg·hm-2,692 kg·hm-2 respectively,but the organic fertilizer N,P2O5,K2O were 177 kg·hm-2,138 kg·hm-2,100 kg·hm-2.The percentage of organic fertilizer was low,which was 2735%,besides the species was miscellaneous,the proportion of chicken manure,sheep dung and commodity organic fertilizer 9561%,and the main mode of irrigation was traditional irrigation and furrow irrigation whose percentage was 9370%,drop irrigation was 630%;the main frequency was 3-4 in the growing season of apple,compared to drop irrigation,the dosage of each time irrigation more than 140%,100%.The analysis of the mode of Boundary line showed that under the highest yield of apple the best dosage of nutrient was 61650 kg·hm-2,37190 kg·hm-2,55310 kg·hm-2respectively,the percentage of the contribution to the yield were 2800%,1760%,2260% respectively.In a word,in Xingtai,the dosage of nutrient was high,and it was partial to inorganic fertilizer,the kind of fertilizer was miscellaneous.The main mode of irrigation was traditional irrigation and furrow irrigation,the waste of water was serious.
