Problems solved by technology

Jinaoline castration agent is currently widely used in wheat hybrid breeding, but chemical castration has not been widely used in forage breeding. At present, manual castration is still used. Manual castration is labor-intensive and time-consuming, and it is easy to break anthers, resulting in castration. fail
So far, only the chemical detasseling method has been used for bluegrass, and there is no effective method for chemical detasseling of brome and reed fescue

Embodiment 1

[0026] Embodiment 1 uses Jin Aoline to detassell the method of flat tassel brome as follows:

[0027] First prepare Jinaoline castration liquid, get concentration and be that 110ml of Jinaoline aqueous solution of 35% is dissolved in water, be settled to 16.7 liters to get castration liquid, stand-by; When the length of the leaf sheath is 0.5cm, every 667m 2 16.7 liters of detasseling liquid was sprayed on brome flat ear.

Embodiment 2

[0028] The method that embodiment 2 uses jinaoline to carry out detasseling of brome bract:

[0029] First prepare jinaoline castration liquid, get concentration and be that 110ml of 33% jinaoline aqueous solution is dissolved in water, add the softening agent trisodium citrate of 24.5g and the surfactant ethylene glycol phenyl ether acetate of 41.6g fully After dissolving, be fixed to 16.7 liters to obtain detasselling liquid, stand-by; 2 Spray 16.7 liters of detasseling liquid on brome and reed fescue. Castration rate can reach 100%.

Embodiment 3

[0030] Embodiment 3 uses the method for detasseling reed-shaped fescue using jinaoline:

[0031] First prepare jinaoline castration liquid, get concentration and be that 110ml of 30% jinaoline aqueous solution is dissolved in water, add the softening agent trisodium citrate of 24.5g and the tensio-active agent ethylene glycol phenyl ether acetate of 41.6g, Set the volume to 16.7 liters to get the detasseling liquid, stand-by; when the young ears of reed-like fescue grow to a length of 1.5cm in the leaf sheath, every 667m 2 Spray 16.7 liters of detasseling liquid on brome and reed fescue. The emasculation rate of reed fescue after spraying can reach 97%.

Abstract

The present invention discloses the application of chemical castrating agent Achor in castrating rescuegrass and reed fescue and the usage. Achor solution of 30-35 % concentration and in 110 ml, softener in 24.5 g and surfactant in 41.6 g are dissolved in water to form 16.7 L of chemical castrating agent solution. The 16.7 L of chemical castrating agent solution is sprayed to rescuegrass and reed fescue in 667 sq m area after the young ears of rescuegrass and reed fescue grow to the intravaginal length of 0.5-2.0 cm. The present invention can reach high castrating effect, and castrating rate of 100 % for rescuegrass and 97 % for reed fescue. The said technology may be also used in castrating treatment of other graminaceous pastures.

Description

technical field [0001] The present invention relates to the application of jinaoline in the detasseling of plants and the detasseling method thereof, in particular to the application of jinaoline in the emasculation of brome and reed fescue and the detasseling method thereof. Background technique [0002] Bromus cartharticus Vahl. is a species of Bromus genus Poaceae. It is a short-term perennial herbaceous plant that likes warm and humid climate. It can harvest three or four stubbles a year. It can produce about 7500kg of hay per hectare and 1500 seeds per hectare. -2200kg / ha. It has good palatability, can be fed green, and can also be made into hay in the sun. Brome is the best local forage grass found in Guizhou Province. It has the advantages of strong stress resistance, high grass yield, and good nutritional value. It is a high-quality forage grass. Hybridization of it with the introduced pasture can breed new varieties of forage grass with higher yield and strong adap...
