碱性竹笋专用配方肥研发及肥效试验初报

根据雷竹林的需肥规律、土壤供肥性能和肥料效能，选用碱性的肥料原料，研究配制了碱性竹笋专用配方肥料。土壤酸化的雷竹林施用该肥料后，自然出笋林和覆盖出笋林的土壤pH值分别平均增加0.53和0.18；有机质分别提高9.76%和7.69%；土壤速效氮、速效钾的含量均有所降低；专用配方肥的施肥量较常规肥料减少42%以上，但产笋量平均增加10%以上，笋品质明显提升。碱性竹笋专用配方肥可以起到一肥多效的效果，对保护生态环境、保障食品安全、促进雷竹林可持续发展都具有重要意义。

Development and Preliminary Efficiency of the Special Formula Alkaline Fertilizer for Bamboo Shoot

According to the fertilizer requirement, soil fertility performance and fertilizer effect of Phyllostachys praecox forest, the materials for alkaline fertilizer are selected to develop the special formula fertilizer for bamboo shoots. After the application of the fertilizer on the acidized Ph. praecox forest, the soil pH values of the natural shooting and the covered shooting bamboo forests increased by an average of 0.53 and 0.18, respectively; the organic matter increased by 9.76% and 7.69%, respectively; the contents of soil available N and available K decreased to some extent; the fertilizer amount was 42% less than that of the conventional fertilizer, but the quantity of shoots increased by more than 10% on average with obviously better quality. The alkaline formula fertilizer specially for bamboo shoots showed the multiple effects, which is of great significance for protecting the ecological environment, ensuring food safety and promoting the sustainable development of Ph. praecox forest.
