<b>Abstract</b>: In this experiment, the graft survival rate, 1a branching volume, overwintering condition, fruit yield, etc. of the five varieties (lines) of Ping'ou hybrid hazelnut in the low-yield hazelnut grafting were investigated and the affinity was observed, and the results showed that the varieties suitable for grafting as hazelnut trees in the five varieties (lines) of Ping'ou hybrid hazelnut were Liao-Hazel 8, 1-21 (strain) and Jade Pendant, of which Liao-hazel 8 and 1-21 (strain) were the best grafted spikes. The yield of the third year of grafting has reached more than 0.5kg, which is drought-resistant and cold-resistant, and has good affinity.

<b>Abstract</b>: Spruce parietal flatleaf bee belongs to the hymenoptera flatleaf bee family, and is a pest that feeds on spruce conifers. The pest occurs in one generation a year and overwinters under the ground as larvae. Pupae begin in late April to early May of the following year, feathering adults begin in early May and fly out from under the soil, spawn on spruce conifers in mid-to-late May, the larvae hatch and feed on the conifers, and from late July to the end of August, the mature larvae fall into the soil for the winter. The needles of the affected spruce turn yellow to the point where the branches wither, and the entire canopy is severely burned like a fire, weakening or even dying.

<b>Abstract</b>: Through the experimental study of different bee insect ratios, different bee release time, different bee release carriers, and different bee spacing between Guan's swollen-legged bees and poplar perpendicular moths, the results show that the bee-worm ratio is positively correlated with the control effect, the optimal bee release time is late July, different bee-releasing vectors have little impact on their control effects, the method of bee-by-plant release is the best, the control effect reaches 71.42%, and the average colonization rate of swollen-legged bees in the forest is about 7.7%. This shows that it is feasible to apply Guan's swollen-legged bee to control poplar perforated moth in the western part of Jilin Province.

(Dongfeng County Forestry Bureau, Liaoyuan 136300, Jilin, China)
<b>Abstract</b>: In 2017, dongfeng county was surveyed on the epidemic situation of pine wood nematode disease, and the host area of pine wood nematode disease was 58334 hm2 in the whole county, of which 1939 hm2 was pure forest of korean pine, 6491 hm2 of pure forest of oil pine, 10612 hm2 of pure forest of sassafras pine, 29542 hm2 of pure larch forest, 192 hm2 of pure forest of red bark spruce and 9558 hm2 of mixed coniferous forest. No pine wood nematode distribution was found in the census. In the future, on the one hand, we will strictly implement the phytosanitary requirements system, do a good job in re-inspection work, and prevent the invasion of the epidemic; on the other hand, we will assist in monitoring by setting up Songmo Tianniu, Spruce Flower Ink Tianniu, and Spruce Xiaomo Tianniu traps, and monitor the dead corners of complex areas through artificial intelligence aircraft.

<b>Abstract</b>: In this paper, the scientific research monitoring data of the white crane system that stopped in the Xianghai Nature Reserve in 2015 were analyzed, and the results showed that the white crane replenished its physical strength in the xianghai wetland in late March, inhabited the shallow bubble swamp and low-humidity meadow, and flew north in late April, and stopped in the sea wetland in late September in the autumn, inhabited the low-humidity meadow and farmland, and basically left the country in early November to fly south for wintering. The impact of serious anthropogenic interference and the drought of wetlands in the core area of cranes in xianghai nature reserves on white cranes is pointed out, and the strategies for strengthening the management and protection of white crane habitats and ensuring water replenishment to sea wetlands are proposed.

<b>Abstract</b>: Based on the multi-year observation data of the National Positioning Observation and Research Station of the Forest Ecosystem of Bingli Mountain in Liaoning Province, the characteristics of the change of meteorological elements in the Liaoning Bingli Mountain were studied, and the results showed that the annual temperature from 2007 to 2016 showed a unmodern cycle change, with 80% of the peak occurring in July and 90% of the valley value appearing in January. The air humidity is the lowest in April and May, and the highest air humidity in July, August and September. The total amount of precipitation is unevenly distributed, the maximum precipitation year is 2.4 times that of the minimum year, the winter precipitation is less, the summer precipitation is more, and the precipitation is concentrated in the growing season. Bingli Mountain is located in the westerly wind belt and has a southwesterly wind that prevails throughout the year. The monthly average of total radiation each year is approximately unipolar, with peaks occurring in May, June and July, of which 50% peak in May and valleys in December.

<b>Abstract</b>: Based on the dynamic monitoring of forest resources in Yantai City, Shandong Province in 2016, this paper proposes the main issues such as the definition of concepts such as forest land and forest species, afforestation management and investigation of non-forest land, management of forest resources archives, application of "one map" and interpretation of detailed rules, and application of geo-information software in the management of forest resources. It also put forward four suggestions and countermeasures, one is to implement the management attributes of forest land, strengthen the protection of public welfare forest resources, and ensure the safety of ecological redlines; the second is to strengthen long-term monitoring of economic forests and non-forest forest resources to ensure forest coverage; the third is to improve the awareness of forest resource archives and strengthen the application of "one map" of forest land; the fourth is to strengthen the training of professional personnel for forest resource monitoring.
