Embodiment Construction

[0016] Vinblastine, CAS No.: 865-21-4, is available from Chengdu Zhibiao Huachun Biotechnology Co., Ltd.

[0017] The preparation method of the compound MannolideA involved in the present invention can be found in the literature: (Mannolides A–C withan Intact Diterpenoid Skeleton Providing Insights on the Biosynthesis ofAntitumor Cephalotaxus Troponoids, Org. Lett., 2016, 18(8), 1880–1883).

[0018] Effect test:

[0019] The test material poplar, produced in Jiangsu Province, is 5-10 years old and has no defects. Peeled and processed into finely planed poplar wood strips, and air-dried to a moisture content of 12% to 15% in a natural environment. In this experiment, all poplar wood was processed into 40mm×30mm×6mm (length×width×thickness) samples.

[0020] Mold: Aspergillus nigerV.Tiegh (Aspergillus nigerV.Tiegh), Penicillium citrintimThom (PenicilliumcitrintimThom), bacterial classification is provided by Institute of Wood Industry, Chinese Academy of Forestry Sciences.

Abstract

The invention discloses a wood preservative containing a compound MannolideA. The weight part ratio of MannolideA to vinblastine is (1:1)-(30:1). The invention discovers that matching the MannolideA and the vinblastine according to a specific ratio achieves a favorable wood preservation effect; and especially when the weight part ratio of the MannolideA to the vinblastine is (23-25):1, the synergic preservation effect is very obvious.

Description

technical field [0001] The invention relates to a preservative, in particular to a wood preservative containing compound MannolideA, and belongs to the field of agricultural technology. Background technique [0002] So far, the most commonly used method to prevent wood decay is to use chemical antiseptics. Leakage and seepage of preservatives during production and use, as well as waste and burning of preservative treated wood will have adverse effects on the environment and endanger human health. healthy. As environmental issues are getting more and more attention, it has also become the key to choosing preservatives. [0003] Water-soluble preservatives are currently the most used, accounting for about 3 / 4 of the total amount of preservatives used. Since the range of a single preservative against wood rot fungi and insects is relatively narrow, two or more preservatives are generally mixed in a certain proportion, which can not only overcome the shortcomings of a single p...
