光慈菇的规范化栽培技术研究——施肥试验

Study on Good Agricultural Practice for Tulipa edulis (Miq.) Baker (Fertilization Experiments)

研究光慈菇的需肥规律和最佳施肥方案。根据农业部的测土配方施肥技术规范"3414"完全实施方案,对光慈菇Tulipa edulis (Miq.) Baker进行施肥试验,探索施肥对光慈菇的产量、增产率、平均单粒重等的影响,采收后利用3414田间试验设计与管理系统和Stata统计软件对产量和施肥进行回归和方差分析。结果:产量与K肥的施肥量成直线关系,回归方程为Y=51.367+1.810X;处理10(N2P2K3)的产量、增产率、平均单粒重、大于2.0g的鳞茎的比例都是最高的,同时其产量、增产率、大于2.0g鳞茎的比例都显著高于空白对照N0P0K0;而且处理10(N2P2K3)的大于2.0g鳞茎的比例显著高于其他13个处理。钾肥对光慈菇的生长是最重要的。

According to ＂3414＂ completely implemented scheme of soil testing which is a fertilization technical specification formulated by the Ministry of Agriculture of China, investigators conducted fertilization experiments on Tulipa edulis （Miq.） Baker, apply 3414 field test design and management systems and Stata statistical software to regression and variance analysis of the output and fertilizer quantity, and studied the rule of fertilization on T. edulis. The results showed that： the yield, the rate of increase, the average weight of single bulb, the proportion of the bulbs that greater than 2.0 g of treatmentl0 （N2P2K3） were highest; at the same time, the yield, the rate of increase and the proportion of the bulbs that greater than 2.0g of treatment10 （N2P2K3） were significantly higher, than those of treatment0 （NOPOK0）; moreover, proportion of the bulbs that greater than 2.0 g of treatmentl0 （N2P2K3） was significantly higher than the other 13 treatments. In addition, there＇s positive correlation between the yield and potash quantity obey linear relation： Y=51.367＋1.810X. So we can edulis. fertilizer, the output and potassium fertilizer draw a conclusion： potash manure is critical to T.
