八渡笋配方肥与普通复合肥等量施用效果的研究

目的]为八渡笋的生产制定科学的施肥对策提供理论依据。方法]以田林八渡笋为试材,进行测土配方专供肥与普通复合肥的施用效果对比试验。结果]在不同施肥处理条件下,施用配方肥能提高八渡笋的产量,改善感官品质。其中,在施肥量相同(2.0kg/丛)的情况下,施用配方肥最终收获时出笋株数、笋茎、株高、带箨笋产量及去箨和粗纤维笋的产量分别比施用普通复合肥提高了10.1%、18.6%、6.4%、20.5%、20.8%;施用配方肥笋株的金黄有光泽比例比施用普通复合肥提高了18.2%,投入产出比可达1.0∶13.0。结论]施配方肥能有效提高八渡笋的农艺性状、产量与经济效益,可在生产上推广使用。

Comparative Study of Formula Fertilizer and Common Compound Fertilizer on Badu Bamboo Shoots under the Condition of the Same Amount Fertilizer Application

Objective] The research aimed to provide theoretical basis for the establishment of applying fertilizer method of Badu bamboo shoots.Method] Comparative tests of the application effects of formula fertilizer and common compound fertilizer with Tianlin Badu bamboo shoots were studied.Result] Applying formula fertilizer could improve yield and sensory quality of Badu bamboo shoots between these fertilization treatments.Compared with common compound fertilizers,formula fertilizer treatment increased the number of bamboo shoots,length of stem,height,yield of Badu bamboo shoots with sheaths and without sheaths by 10.1%,18.6%,6.4%,20.5% and 20.8%,respectively under the fertilization quantity of 2.0 kg /clump.And the golden luster ratio was increased by 18.2%.The input-output ratio of formula fertilizer with the fertilization quantity of 2.0 kg /cluster was the best,up to 1.0∶13.0.Conclusion] Applying formula fertilizer could improve the agronomic characters,the yield,the sensory quality and the economic benefits,which was suggested to be spread in production.
