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.
