以重庆市荣昌区退耕还林区麻竹林下竹荪为对象,进行了仿野生种植关键技术研究。笔者分别测定了竹荪的发菇时间、鲜/干质量、菌柄长度与发菇期的温度,探讨了不同栽培处理方式对竹荪产量的影响,并对仿野生竹荪的品质及其效益进行了分析。结果表明:1竹荪产量随着时间推移呈一定的波峰分布,林内气温超过35℃时竹荪生长明显受到抑制。2对麻竹林下竹荪仿野生栽培的关键技术要素进行了优化配置,以基质用法的影响最大且极显著,菌种用量的影响次之,郁闭度影响最小,且后两者差异不显著。3兴农D89为在重庆荣昌地区麻竹林下种植竹荪的最优菌种,其最佳种植模式为:3月初,菌种用量5×10~3kg/hm~2,以不同基质分层施放,即下层竹叶6.67×10~4kg/hm~2,上层竹屑8.33×104kg/hm~2,林分郁闭度控制在0.6。此条件下,鲜竹荪产量和净收入分别可达到1.536 0×10~4kg/hm~2和2.418 9×10~5元/hm~2。 Taking the Phyllostachys heterocycla cv. Phyllostachys heterocycla cv. Phyllostachys pubescens forest in the area of ​​returning farmland to forest in Rongchang District of Chongqing Municipality as an example, the key technologies of imitation wild plantation were studied. The authors determined the germination time, the fresh / dry weight, the length of the stipe and the temperature of the germinating period respectively, and discussed the effects of different cultivation methods on the yield of the Dictyophora. The quality and efficiency of Dictyophora Analyzed. The results showed that the production of P. echinulata showed a certain peak distribution with time, and the growth of D. punctatus was obviously inhibited when the temperature in the forest exceeded 35 ℃. 2, the key technical factors of imitation rhizomania rhizophyllum of Phragmites australis were optimally allocated, the influence of matrix usage was the largest and the most significant, followed by the amount of bacterial species, followed by the canopy density, and the latter two had no significant difference . 3 Xingnong D89 is the best species for planting Dictyophora under bamboo and bamboo groves in Rongchang, Chongqing. The optimum planting mode is: In early March, the amount of bacteria is 5 × 10 ~ 3kg / hm ~ 2, , That is, the lower bamboo leaves was 6.67 × 10 ~ 4kg / hm ~ 2, the upper bamboo leaves was 8.33 × 104kg / hm ~ 2, and the canopy density was controlled at 0.6. Under this condition, the yield and net income of fresh bamboo can reach 1.536 × 10 ~ 4kg / hm ~ 2 and 2.418 × 10 ~ 5yuan / hm ~ 2 respectively.
