Mustard five kinds of attention
In order to ensure the excellent seed quality of good mustard, you should pay attention to the following aspects when you leave the seed. First, do a good job of segregation: In order to ensure the purity of the varieties, natural segregation will be applied to the reserved areas for the production of large-area seeds for the second year of breeding; for the species used for breeding in the second year of breeding, fine individual plants shall be selected and sand covers be used. Manually isolated and single collection. Second, to go to miscellaneous miscellaneous: leave the planting site only to retain the shape of a good, with the characteristics of the species characteristics, robust growth, no pests and diseases, convulsions consistent plants. All miscellaneous and inferior plants that do not meet this standard will be removed. Third, the implementation of topping: 10-15 days after flowering to remove the main inflorescence and the top part of the inflorescence of the top, no longer let it continue to bloom, so that nutrients concentrated supply of the remaining fruit, to ensure that the development of good fruit, grain size and weight. Planting toppings is a cost-effective measure to increase production. Fourth, pest control and disease prevention: In order to control aphid-based pests (and cure virus disease), the agent can be used imidacloprid 15 grams per acre plus water spray control. 5. Timely harvesting: When the lower middle pod of the plant turns yellow and the grain becomes brown, it can be harvested and bundled in bundles, placed in a cool, well-ventilated place, and cooled and dried to thresh. After the threshing, the seeds are covered with paper or cloth and dried. It is not advisable to expose the sun under the hot sun. Due to a longer exposure time, the germination rate of seeds dropped significantly. After the seeds are dried, they should be stored in a jar and placed in a ventilated, dry place for storage.
