Multivariate fertilizer combined fertilizer applicator

Abstract

The invention discloses a combined fertilization machine for compound fertilizers and belongs to agricultural machinery. The combined fertilization machine consists of a stander, agricultural fertilizer boxes, a chemical fertilizer box, furrowers and covering blades, wherein the agricultural fertilizer boxes and the chemical fertilizer box are fixed at the upper part of the stander; an agricultural fertilizer feeder assembly is arranged at an outlet in the bottom of each agricultural fertilizer box; the furrowers fixed on the stander are arranged in front of fertilizer outlets (a) in the bottoms of the agricultural fertilizer feeder assemblies; the covering blades and ridgers which are fixed on the stander are arranged behind two sides of the fertilizer outlets (a) on the stander; chemical fertilizer feeder assemblies are arranged on the chemical fertilizer box; fertilizer outlets (b) of the chemical fertilizer box extend between the covering blades and the ridgers. An agricultural fertilizer and chemical fertilizer combined fertilization machine is higher in generality and can be used for fertilization, rest-balk building and pressing; the fertilization depth is uniform, soil covering is consistent, and the fertilization amount is uniform; the pH value of soil can be adjusted, and the soil structure can be improved.

Description

technical field [0001] The invention belongs to agricultural machinery, in particular to a multi-component fertilizer combined fertilizer applicator. technical background [0002] In recent years, agricultural production in most areas has relied too much on chemical fertilizers, ignoring the more labor-intensive organic fertilizers such as compost and green manure, and the arable land focuses on output rather than input; The increase year by year has brought about an imbalance in the ratio of nitrogen, phosphorus and potassium, and a decline in soil fertility, which has made agricultural production more and more dependent on chemical fertilizers and further degraded the quality of cultivated land. In the past, due to the single application of chemical fertilizers, the cultivated layer became shallower, which not only caused droughts and floods, but also burned the seedlings with chemical fertilizers. In agricultural production in many areas, farmers have two incorrect tende...
