Field Experiment on Direct Seeding Conducted at the Cascata Experimental Station of Embrapa Temperate Climate, 2022 (with supplementary material)

This dataset contains records from a direct seeding experiment conducted in 2022 at the Cascata Experimental Station of Embrapa Temperate Climate. The objectives of the present study were to investigate the effects of season, mulching, and agricultural crops on the emergence and establishment of tree species (pioneer and non-pioneer) through the use of direct seeding in forest restoration under a subtropical climate. The field observations presented show the emergence of the tested forest species over one year of study, as well as their establishment one year after implementation. The different factors tested were agricultural crops (Treatment 1), with the levels presence of agricultural crops (T1) and absence (Control). The mulching factor (Treatment 2), with the levels presence of mulching (Mulching) and absence (Non-mulching). The seasons tested were summer and winter, and finally, the successional groups included pioneer and non-pioneer species.本数据集收录了2022年在巴西农牧业研究公司（Embrapa）温带气候研究中心卡斯卡塔试验站开展的直播造林（direct seeding）试验相关记录。本研究旨在探究亚热带气候下森林恢复（forest restoration）场景中采用直播造林模式时，季节、地表覆盖（mulching）与农作物对先锋树种（pioneer species）及非先锋树种（non-pioneer species）出苗与定植效果的影响。本数据集所呈现的野外观测数据，涵盖了为期一年试验周期内供试林木物种的出苗情况，以及试验实施一年后的定植存活状况。本次试验设置的考察因子包括农作物因子（处理组1），其水平设置为施加农作物（T1）与不施加农作物（对照组）；地表覆盖因子（处理组2），其水平设置为施加地表覆盖（Mulching）与不施加地表覆盖（Non-mulching）；试验考察的季节因子涵盖夏季与冬季；最后，试验涉及的演替类群包括先锋树种与非先锋树种。
