In order to fulfill that the cropping system of intercropped peanut is reformed from "triple cropping in two years system" to "summer seeding system" and comprehensively research the growth regularity of summer-planting peanuts, in this paper, pool-culture experiment was conducted to analyze the flowering phenology processes and reproductive characteristics of the peanuts under 3 different planting systems, to conduct mathematical analysis on the changing development within, as well as to explore the flowering phenology
indexes and the fructification differences of peanuts planted by different methods, providing basis for the perfection of high-yield culture technique of summer-planted peanuts. The results show that the summer planting plastic-film-covered cultivation can accelerate the peanuts early stage of growing process, shorten the period from germinating to flowering by about 8 days, improve the index of synchronous flowering, making the flowering period more intensive. Compared with interplanting cultivation, the summer planting plastic-film-covered cultivation can improve max flowering amount of single plant by 5%, increase fruit pin number by 20%, extend full bloom period by 7 days. increase single plant fruit number by 20%, increase single plant
full-pod rate by 15.8%, and enlarge the pod volume by 12.2%. The experiment indicated that the summer-planted peanuts are also equipped with the high-yield potential.Through plastic film mulching method, we can overcome the limiting factors such as short growth period and imperfect pods, so as to realize early and intensive fruiting, guarantee the pods number and pods plumpness, laying foundation for high yield. |
