不同种植密度与施肥量对多彩花生农艺性状及产量的影响
Effects of Different Planting Densities and Fertilization Rates on Agronomic Traits and Yield of Colorful Peanuts
摘要
Abstract
In order to explore the optimal planting density and fertilization rate for colorful peanuts and to develop high-yield and high-efficiency cultivation techniques,the new colorful peanut line Shuncaihua 1 was used as the test material.Four levels of planting density and fertilization rate were set,resulting in a total of 16 treatments.The differences in plant traits,branching traits,and yield of colorful peanuts under each treatment were compared and analyzed.The results showed that appropriately increasing planting density and fertilization rate was beneficial to promoting the vegetative growth of colorful peanuts,increasing the total number of branches and effective fruiting branches,improving the full pod rate,full kernel rate,and kernel yield,enhancing yield traits,and increasing yield.Under the treatment with a planting density of 249 000 plants/hm2 and a fertilization rate of 495 kg/hm2,the full pod rate,full kernel rate,and kernel yield rate of colorful peanuts were 88.96％,94.13％,and 69.05％,respectively.The number of effective fruiting branches reached 5.5,the weight of 100 pods reached 290.56 g,the weight of 100 kernels reached 69.05 g,the pod yield reached 5.63 t/hm2,and the kernel yield reached 3.89 t/hm2.This treatment is the optimal condition for high-yield and high-efficiency cultivation of the new colorful peanut line Shuncaihua 1.关键词
