Embodiment 1
[0019] (1) Material selection:
[0020] In March 2018, different types of litter were collected in a fixed plot of Castanopsis geshiba Reserve in Sanming, Fujian Province, which were divided into four types: branches, leaves, skins, and shells, each 4 Kg. The seeds of the recipient plant Schima superba were selected from the second-generation Schima superba species of Zhangping State-owned Forest Farm in Longyan, totaling 1 Kg.
[0021] (2) Extraction preparation
[0022] Crush the collected Castanopsis gritta branches, leaves, bark and husk litter to a size of 1-2 cm, press 1 g·5 mL -1 (Add 5 mL of distilled water to 1 g of dry matter), add an appropriate amount of distilled water, soak at room temperature for 48 h, then filter with clean gauze, and finally filter the filtrate through a vacuum pump to obtain the extraction stock solution. leaching and decomposition, and then mix the extraction stock solution and distilled water according to the volume ratio of 1:10, 1:30, 1...

The invention discloses an inhibitor for growth of schima superba based on castanopsis kawakamii litter leaching solution, and belongs to the technical field of plant protection. The inhibitor is prepared by mixing a castanopsis kawakamii litter leaching solution stock solution and distilled water according to a certain proportion. The preparation method of the castanopsis kawakamii litter leaching solution stock solution comprises the following steps: crushing castanopsis kawakamii litter, adding distilled water according to a certain ratio, soaking for a period of time, filtering with cleangauze, and carrying out suction filtration on an obtained filtrate through a vacuum pump to obtain the castanopsis kawakamii litter leaching solution stock solution. The schima superba growth inhibitor has that the raw materials are easily available, no environment pollution is caused, the preparation method is simple and convenient, and the inhibitor possesses remarkable inhibiting effect on schima superba seed germination. The inhibitor provided by the invention can protect castanopsis kawakamii from the perspective of allelochemical effect, and has important guiding significance for protection of rare tree species communities.
Description
technical field [0001] The invention belongs to the technical field of plant protection, and in particular relates to an inhibitor of the growth of Schima superba based on the extract of Castanopsis gritta litter. Background technique [0002] Castanopsis grisa ( Castanopsis kawakamii ) is an evergreen tall tree with a long growth cycle in the family Fagaceae. It is currently only distributed in parts of the southern subtropical and mid-subtropical regions in China. It is an important target tree species for the rare wild plant protection project in Fujian Province. At present, the constructing species of Castanopsis clematis natural forest has been in decline, the natural regeneration of seedlings is poor, the population of the second generation is small, the big trees are over-matured, and the forest is mainly mixed with Chinese fir ( Cunninghamia lanceolata ), Schima superba ( Schima superba ) and masson pine ( Pinus massoniana ) and other trees. In order to prot...
