Method for preventing and controlling parasitic plants and its special preparation and use of the preparation

Abstract

The invention discloses a method for preventing parasitic plant broomrape, a specific preparation for same and purposes of the specific preparation. The key points of the method are that one or more than two kinds of Strigolactones biosynthesis inhibitors TIS108,TIS13,TIS101,TIS102,TIS103,TIS104,TIS105,TIS106 and TIS107 are mixed according to one proportion to prepare the specific preparation to process broomrape seeds, so the seeds can germinate during a non-growth period and die due to the failure of finding a host and therefore broomrape seed library in the soil can be effectively reduced. By the use of the prevention method, the seeds can germinate during a non-growth period and die due to the failure of finding a host and therefore broomrape seed library in the soil can be effectively reduced. The method can be easily operated and requires low cost and causes no pollution to the environment.

Description

technical field [0001] The invention relates to the field of agricultural biotechnology, in particular to a method for promoting seed germination of plants of the genus Rodang and reducing the seed pool of Rodang seeds in soil. Background technique [0002] Roddang is a class of parasitic plants whose roots are parasitic in the family Orobanchaceae (Orobanchaceae). Orobanche Phelipanche ) The general term for plants. [0003] Because it does not contain chlorophyll, it can only obtain water and nutrients from the host plant through the haustoria. Plants of the genus Lietang can parasitize hundreds of plants such as tomato, sunflower, rape, carrot, broad bean, and melon in Solanaceae, Fabaceae, Compositae, Umbelliferae, and Cucurbitaceae. When the host is listed as parasitic, it will show symptoms such as slow growth, yellowing, wilting, etc., resulting in a decrease in crop yield and quality, or even failure. [0004] At present, about 1.2% of the arable land in the world...

Problems solved by technology

[0012] Recent studies have shown that GR24, a commonly used synthetic strigolactone analogue, can promote the germination of the seeds of the genus Ridang in vitro, but it must be pre-cultivated for a period of time, which makes the entire germination cycle Elongated, the germination rate is greatly affected by other factors
