Problems solved by technology

In recent years, it has been found that poplar bacterial canker has commonly occurred in poplar cultivation areas in the three northeastern provinces of my country, and it is prevalent in a large area, causing huge economic losses
This kind of disease is serious, but there is no good control method at home and abroad. It is found that the occurrence of this kind of poplar disease is closely related to freezing damage

Embodiment 1

[0012] 1 Materials and methods

[0013] 1.1 Screening of indoor chemicals

[0014] 1.1.1 Test material

[0015] There are 4 kinds of medicaments for indoor screening, namely thiram (40% wettable powder), agricultural streptomycin (10 million units of pure powder), difenazol (10% water), antifreeze protection agent, according to different medicaments Choose 4-6 kinds of concentrations to test. Liquid medium formula: 10 grams of peptone, 4 grams of beef extract, 1 gram of NaCl, and 1000 ml of water. , Add 20 grams of agar to the solid medium on this basis. Tested strain: Pantoea aggiomerans.

[0016] 1.1.2 Test method

[0017] (1) Liquid strain culture: After the prepared liquid medium is autoclaved, strain A is inoculated therein. Then place it in a shaker at 30°C for 48 hours, with a concentration of about 10 9 / ml.

[0018] (2) Drug preparation: According to different drugs, 4 or 6 concentrations were selected for testing, see Table 1. Prepare the medicament accordin...

Abstract

The invention discloses an antifreezing protective agent for a poplar and an application method thereof, belonging to a biological technology field. The antifreezing protective agent is prepared from the following raw material by weight: methyl cellulose, pesticide streptomycin, potassium dihydrogen phosphate and water; the application method comprises: spraying a 100-fold diluent of the antifreezing protective agent with water onto poplars; and spraying time and frequency comprise: the antifreezing protective agent is sprayed on the poplars for 1-2 times before the poplars sprout in the early spring or after the poplars fallen leaves in autumn. The antifreezing protective agent provided by the invention can effectively control generation of diseases. Compared with same kind of products home and abroad, the prepared antifreezing protective agent has advantages of low cost, simple drug application method and substantial effect.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to an antifreeze protectant for poplar and its application method. Background technique [0002] Poplar (Populus) is an important afforestation and afforestation tree species in my country. It has the characteristics of fast growth, strong adaptability, wide distribution and easy reproduction. Poplar is one of the important industrial timber species, which can provide a large amount of industrial raw materials, such as particle board, plywood, artificial board and pulp. Poplar plays a huge role in windbreak and sand fixation, water and soil conservation, farmland protection and maintenance of ecological balance. Therefore, many countries in the world attach great importance to the cultivation of poplar. [0003] Vigorously developing the fast-growing and high-yielding poplar forest is one of the effective ways to solve the shortage of forest resources. However, with the gradual expan...
