Embodiment 1

[0034] (1) Preparation of mother liquor: Dissolve 500 g of strigolactone biosynthesis inhibitor TIS108 in 0.4L acetone, then dilute with sterile water until the mass concentration of strigolactone biosynthesis inhibitor TIS108 is 400g / L.

[0035] (2) Application method: Measure 2L of the mother liquor configured in step (1), and drip it into the soil poured with 20 tons of water per mu with the drip irrigation belt when sowing, so that strigolactone biosynthesis in each mu of soil The concentration of the inhibitor TIS108 solution was 100mg / L.

[0036] (3) Germination effect: compared with the per acre of land that did not use the above-mentioned medicament, the germination rate of Liedang seeds per acre of the application of the above-mentioned special medicament was 72.60%. The germination rate of every acre of Liedang seeds is 0%.

Embodiment 2

[0038] (1) Mother liquor preparation: every 500g strigolactone biosynthesis inhibitor TIS108 that takes by weighing is dissolved in 0.5L acetone, then diluted with sterile water to the strigolactone biosynthesis inhibitor TIS108 mass concentration is 500g / L.

[0039] (2) Application method: Take 1L of the mother liquor configured in step (1), and drip it into the soil with 40 tons of water per mu along with the drip irrigation belt when sowing, so that strigolactone biosynthesis in each mu of soil The concentration of the inhibitor TIS108 solution was 25mg / L.

Embodiment 3

[0041] (1) Preparation of mother liquor: every weighed 500g of strigolactone biosynthesis inhibitor TIS108 was dissolved in 0.42L acetone, and then diluted with sterile water until the mass concentration of strigolactone biosynthesis inhibitor TIS108 was 420g / L.

[0042] (2) Application method: Measure 2L of the mother liquor configured in step (1), and drip it into the soil with 38 tons of water per mu along with the drip irrigation belt when sowing, so that strigolactone biosynthesis in each mu of soil The concentration of the inhibitor TIS108 solution was 53mg / L.

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] Phelipanche is a general term for plants belonging to the genus Orobanche Phelipanche of the family Orobanchaceae that live in parasitic life on the roots of a class of parasitic 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 a...
