Zusammenfassung: | To provide a fertilizer distributor capable of correcting soil acidity (pH) of a field by distributing a corrective agent for correcting the acidity of the soil at the same time as fertilizing.SOLUTION: A second discharge pipe 43b of a fertilizer distributor 3 is so configured that a discharge port 44b thereof is located on the rear side of a pair of furrowing disks 21 and 21 and not disposed outside the rear ends of the pair of furrowing disks 21 and 21. Further, the discharge port 44b of the second discharge pipe 43b is not located on the rear side of rear ends of a pair of soil-covering disks 23 and 23 and is clamped between the pair of soil-covering disks 23 and 23. Thereby, the fertilizer distributor can apply a second fertilizer 35 around seeds and root growing areas. Consequently, this constitution can correct acidity in the soil so as to secure favorable germination of the seeds and stable initial growth of the crops, and thereby preventing defective germination and defective growth due to low pH conditions.SELECTED DRAWING: Figure 3
【課題】施肥と同時に土壌の酸度を矯正する矯正剤を適切な位置に散布でき、圃場の土壌酸度(pH)を矯正することができる。【解決手段】施肥機3の第2排出管43bは、その排出口44bが、一対の作溝ディスク21,21の後方側に位置しつつ、一対の作溝ディスク21,21の後端部より外側に配置されないように設けられている。さらに、第2排出管43bの排出口44bは、一対の覆土ディスク23,23の後端部より後方側に位置せず、かつ、一対の覆土ディスク23,23に挟まれるように設けられている。これにより、第2肥料35を種子の周囲及び根の伸長領域にかけて散布することができる。その結果、土壌中の酸度を矯正することができるため、種子の良好な発芽と作物の安定した初期育成を確保し、低pHの条件下による生育不良、発芽不良を防ぐことができる。【選択図】図3 |
