摘要:

为探讨不同花生品种适宜的单粒精播密度,本研究采用二因素三次重复随机区组设计,起垄不覆膜种植,对‘冀花18号’、‘冀农花6号’和‘邢花9号’分别进行了16.5万穴/hm2、19.5万穴/hm2、22.5万穴/hm2和25.5万穴/hm2的单粒精播试验研究。结果表明,不同种植密度对花生产量的影响呈极显著差异;不同种植密度对不同花生品种产量影响不同,差异达极显著水平,其中‘冀花18号’适宜种植密度为22.5万穴/hm2,‘冀农花6号’、‘邢花9号’适宜种植密度均为19.5万穴/hm2。本研究为3个花生品种推广应用奠定了基础。

Abstract:

Three peanut varieties of ‘Jihua 18’, ‘Jinonghua 6’ and ‘Xinghua 9’ were used to explore the suitable density of single-seed precision sowing under the cultivation mode of ridging without plastic film mulching. A 2-factor and 3-level random block design was conducted with sowing densities of 165000 holes/hm2, 195000 holes/hm2, 225000 holes/hm2 and 255000 holes/hm2, respectively. The results showed that the effect of sowing density on peanut yield was extremely significant, and different sowing densities had very significantly different influence on the yield of different peanut varieties. The suitable planting density of ‘Jihua 18’ was 225000 holes/hm2, and that of ‘Jinonghua 6’ and ‘Xinghua 9’ was 195000 holes/hm2. The study can lay a basis for the extension and application of the three peanut varieties.

Key words: peanut, single-seed precision sowing, density, yield
