Fertilizing structure for fertilizer distributor

Abstract

The invention discloses a fertilizing structure for a fertilizer distributor. The fertilizing structure comprises an inner tube and an outer tube. The outer tube sleeves on the outer peripheral side of the inner tube and a bearing is fixed therebetween. The outer tube is driven by a driving device to rotate relative to the inner tube. The upper end of the inner tube is connected to a fertilizer cabin. An arc-shaped bump structure is arranged in the inner tube. First fertilizer discharging ports are formed in two symmetrical side ends of the lower end of the inner tube. Second fertilizer discharging ports are formed in two symmetrical side ends of the lower end of the outer tube. Fertilizing channels which are obliquely formed downward are separately formed in the outer sides of the two second fertilizer discharging ports. The upper ends of the fertilizing channels are used for receiving fertilizers discharged from the second fertilizer discharging ports and the lower ends of the fertilizing channels are used for applying the fertilizers discharged from the second fertilizer discharging ports into furrows. According to the fertilizing structure for the fertilizer distributor for point-by-point fertilization, waste caused by large area application of the fertilizer is reduced, and the utilization ratio of the fertilizer is effectively increased.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a fertilizing structure for a fertilizing machine. Background technique [0002] At present, in the production of solanaceous vegetables in facilities, the traditional mode of farmers planting solanaceous vegetables is to first use manual methods to evenly spread all the base fertilizer on the surface, then shallow plowing (8-10cm) to mix the fertilizer with the topsoil, and then artificially ( or machinery) ridge (or ditch), most of the solanaceous vegetables are planted on the ridge or both sides of the ditch by seedling transplanting. The width of the ridge (or ditch) is generally 60cm, and two rows of vegetable seedlings are planted in one ridge (or ditch); the distance between ridges (or ditch and ditch) is 90cm, which is an open space and is mainly used for manual daily management. After the vegetables are transplanted, topdressing is carried out on the surf...

AI Technical Summary

Problems solved by technology

[0003] There are three disadvantages in the above planting mode: (1) the base fertilizer is applied to the entire surface first and then shallow plowing operation is cumbersome; (2) the distance between ridge and ridge (or ditch and ditch) is 90cm, but a large amount of base fertilizer is still applied , when the seedlings are just transplanted, the root system is relatively small, and the surface nutrients between the ridges (or ditch and ditch) are basically not absorbed, so that most of the fertilizers spread between ridges and ridges (or ditch and ditch) are wasted (3) Determining the available nitrogen, phosphorus and potassium nutrient content in the vegetable field soil by sampling analysis is much higher than 20-40cm in 0-20cm

In traditional fertilization, all the phosphorus fertilizers and 1 / 5-1 / 2 nitrogen and potassium fertilizers needed for the whole growth period of vegetables are evenly spread on the ground in the form of base fertilizer, resulting in a huge waste of nitrogen, phosphorus and potassium fertilizers
