In the autumn, various crops have matured one after another. It is a good time to choose to leave crop seeds. As the saying goes: “It is a good idea to produce a good scoop, so that good seedlings can be plantedâ€. This fully shows that selecting and keeping good seeds will play an important role in seizing the agricultural harvest of the following year. First, the election to retain the standard selection of agricultural crop seeds, must have the following conditions: 1, straw neat, stout not fall; 2, large spikes and more grain full; 3, uniform color, no pests and diseases; 4, high yield stability, good quality. Second, the selection method 1, block selection election, the spring to establish a plot to stay in the field, can be selected or chip selection. When choosing to stay, remove the miscellaneous strains, diseased strains, and weak strains, and then mix and select them for planting. 2, the selection of panicles. Prior to the autumn harvest, plant selection and panning were carried out on plots that were planned to be planted. For strain selection and panicle selection, we must first fully understand the characteristics of the variety, and then select the single plant and single ear that grow robustly, have strong resistance, and have large grain and grain filling. 3, positioning is preferred. That is, according to the best genetic advantage of crops to select the species, also known as the positioning of seed selection. Positioning and seed selection can fully transfer the excellent performance of the variety to the next generation, and fully and effectively exert the improved yield performance of improved varieties. The best genetic advantage of several crops is: Corn: It is the dominant crop in the central region. Its best genetic advantage is in the middle and lower part of the ear. The seeds used for this species are 35.4% more than the top. Sorghum: It is the top dominant crop. The grains in the upper part of the ear are full, full, well developed, strong in growth, and have strong genetic advantages for the high-yield traits. The use of seeds with more than 1/3 of total spikes as a seed was 8.7% higher than that of seeds with mixed whole ears. Rice: It is a dominant crop at the top. The upper part of the panicle is full and full of grains. The weight of one thousand grains is high and its growth ability is strong. The upper grain is used as a seed to produce 13.2% and 17.4% more than the middle and lower grains, respectively. Soybean: It is a dominant crop in the central region and has a limited breeding habit. The strongest genetic advantage is in the upper part of the main stem; the indeterminately knotted variety is in the lower part of the main stem; Plant selection in the strong genetic predominance can generally increase production by about 10%. Third, the matters needing attention 1, the fall selection, is limited to self-crop crops, hybrid crops should not choose to retain the seeds. 2. After selecting the seeds, we must pay attention to drying and dehydration, so that the seed moisture falls within the safe moisture range so that the seeds can be safely stored for winter.
