Abstract: | [ Objective ] The aim was to provide a scientific basis for application of single-seed precision sowing technology in rapid propagation of new good peanut varieties. [Method] Choosing the multi-grain type peanut variety Jihua No. 3 as experimental material, a systematic study was conducted on the effects on plant traits, yield and reproduction coefficient of peanut under the costsaving effective high yield single-seed preeision sowing cultivation technology in field and effective single-seed precision sowing rapid propagation technology in greenhouse. [ Result] The two kinds of single-seed precision sowing technology significantly reduced the plant height, increased the number of fruit per plant and pod rate, improved production and propagation coefficient of peanut, and the reproduction coeffieient of the effective single-seed precision sowing rapid propagation technology in greenhouse reached to 34.3, 84.5% higher than that of the conventional two-particle dibble. [ Conclusion] The two kinds of single-seed precision sowing technology have obvious effects on saving seed, increasing production and raising propagation coefficient, can be used as a viable rapid propagation technology of new peanut varieties. |
