The invention relates to the field of pesticide herbicides, and discloses a cyclohexanetrione compound and a preparation method and an application thereof, and a herbicide; the compound has a structure represented by a formula (I). The cyclohexanetrione compound provided by the invention can be used as an HPPD herbicide for controlling and killing gramineous weeds, and has a good control effect onbrome, wild oat, aegilops tauschii, alopecurus amurensis, alopecurus japonicus and other gramineous weeds which are difficult to control.

The invention discloses a post-seedling compound herbicide for wheat seedlings. The post-seedling compound herbicide comprises tralkoxydim and flucarbazone, the mass percent content of the tralkoxydim and the flucarbazone accounts for 0.1-85% of the total mass of the post-seedling compound herbicide, wherein the weight ratio of the tralkoxydim to the flucarbazone is (0.1-60) to (0.1-70). In comparison with a single medicament of the tralkoxydim and the flucarbazone, the use amount of the compound herbicide is low, the cost is low, and the prevention effect to monocotyledonous weeds and dicotyledon weeds in a field, the fresh weight prevention effect and the comprehensive fresh weight prevention effect are improved, and the security and the fast-acting property to the field crops are obvious. The weeds in the whole growth season of crops can be prevented and controlled through once pesticide application, the compound herbicide is safe to next-stubble crops, and especially has special effects to the resistance weeds such as aegilops tauschii and bromus japonicus in North China.

The invention provides a DNA bar code for discriminating aegilops tauschii and aegilops cylindrica and an application thereof. A nucleotide sequence of DNA bar code is shown in as SEQ ID NO: 1-2. By designing a pair of novel DNA bar code primers, an optimal identification sequence is obtained, the DNA bar code sequences of aegilops tauschii and aegilops cylindrica in a Genbank database are improved, aegilops tauschii, aegilops cylindrica and aegilops umbellulata can be distinguished by only one pair of the primers, and the unknown aegilops tauschii and aegilops cylindrica can be rapidly identified. Compared with a form characteristic identification method at a growth anaphase, the DNA bar code breaks up the restriction of an identification period, greatly increases the identification efficiency, increases the detection speed and accuracy, is in favor of guidance for timely controlling two wheat field worst weeds for an agriculture production mechanism and peasants, ensures the production safety of wheat and peasant income, reduces the threat to national food security, and has good economic benefit and social benefit.

The invention discloses an agricultural method for controlling Aegilops tauschii weeds in winter wheat fields. The method comprises seeding time adjustment, induction emergence, chemical seedling induction, emergence acceleration, weed killing with flames and rational close planting. The method has the benefits as follows: the method is safe, efficient, environment-friendly and convenient and quick to operate and only takes agricultural measures, no chemical herbicides are used, time and labor are saved, environmental pollution, ecological damage, crop pesticide residues and the like caused by use of chemical herbicides can be effectively reduced, so that green control on Aegilops tauschii in winter wheat fields in the production practice is guided, and the safety of agricultural products is improved.

The application of the invention belongs to the technical field of wheat molecular breeding, and particularly relates to serial molecular markers and an application thereof to pre-harvest sprouting gene molecular markers. The number of the molecular markers is 4, the molecular markers comprise an SSR marker and three KASP markers, wherein the SSR maker is an Xgwm383b marker, and the three KASP markers are A009711, A009180 and A009716. During variety breeding, the way of transferring excellent genes in aegilops tauschii to wheat is mainly to create a series of wheat / aegilops tauschii substitution line, and through distant hybridization means, aegilops tauschii chromosomes are introduced into wheat background. In accordance with the breeding method, practical F2 groups are used as an example, the serial molecular markers are designed to be used for detecting and tracking the situation of the aegilops tauschii chromosomes introduced into the wheat background, and further guiding pre-harvest sprouting resistant new species cultivation, and the serial molecular markers have better practical value.

The invention discloses picolinamide compounds as well as a preparation method and application of the picolinamide compounds. The structural general formula of the picolinamide compounds is shown in the specification. Relevant biological activity tests find that certain compounds can generate specific brassinolide reaction and are capable of promoting the elongation of hypocotyledonary axis of an arabidopsis mutant det2-1 in the dark, increasing of dip angles of rice leaves, enhancing the salt stress resistance of corns and the like. An individual compound has a very high response value at a lower concentration, is capable of inhibiting the plant height of wheat, delaying the growth and improving the lodging resistance at a high concentration and simultaneously has very good effects of preventing and treating gramineous weeds such as wild oat grass, aegilops tauschii, barnyard grass, setaria viridis and goat grass.
