A method and a device for discharging fertilizer for agricultural cultivated plants are disclosed. According to the invention, the required quantity of fertilizer is determined depending on the current nutrient uptake (nutrient status), optimum nutrient uptake (nutrient requirement) by the fertilizing deadline, and optimum nutrient uptake (nutrient requirement by the next fertilizing deadline, wherein other influencing factors are taken into consideration via a correction factor DIMA.

The invention discloses a method for using an all-in-one sprinkler and irrigation machine capable of simultaneous precise fertilization or spraying of pesticides, specifically comprising the following steps: a. preparation for spraying irrigation and simultaneous precise fertilization or spraying of pesticides; .Spray irrigation synchronous precise fertilization or pesticide spraying; e. Synchronous precise fertilization or pesticide spraying control; f. Control after PE pipe recycling. The method of using the sprinkler and irrigation all-in-one machine that can simultaneously accurately fertilize or spray pesticides can realize the convenience of spraying according to the instructions and at the same time carry out precise fertilization or spray pesticides, and then realize efficient fertilization or efficient spraying of pesticides while achieving efficient sprinkling irrigation; when PE pipes are recycled It is to fertilize or sprinkle medicine on the irrigated farmland, so as to ensure that the fertilizer or medicine is better absorbed by the farmland, and at the same time, it can prevent excessive fertilizer or medicine from remaining on the surface of the farmland, thereby preventing pollution of the environment. It is especially suitable for large-scale crops Precise fertilization or spraying of pesticides.

The invention discloses a greenhouse crop fertigation method, belonging to the field of modern agricultural precision fertigation. The method is characterized by obtaining the concentration information of nitrate ions, ammonium ions and potassium ions in the crops by using an ion selective microelectrode, comparing the concentration information with the ion concentration in the same period in the plants normally supplied with fertilizers to obtain the ion concentration difference and determining the fertigation amount of nitrate nitrogen fertilizers, ammonium nitrogen fertilizers and potassium fertilizers. The method can be used in the field of modern agricultural precision fertigation and is beneficial to increasing the fertilizer utilization rate and the yields and quality of the crops.

The invention relates to a multifunctional slow-release fertilizer applicator. The multifunctional slow-release fertilizer applicator comprises a through water pipe, a fertilizer container, a fertilizer-water drainage pipe and a branched pipe, wherein the fertilizer-water drainage pipe is arranged in the fertilizer container, extends outwards and is communicated with the through water pipe; through holes are formed in the fertilizer-water drainage pipe, and the fertilizer-water drainage pipe is connected with the fertilizer container; the through water pipe is provided with a water inlet and a water outlet; an openable-closable fertilizer feeding hole is formed in the upper end of the fertilizer container; one end, close to the water inlet, of the through water pipe is communicated with the lower end of the branched pipe, the upper end of the branched pipe is communicated with the fertilizer container, and the water outlet of the through water pipe extends out of an irrigation pipe section; in a fertilizer applying process, water can be replenished to the fertilizer container by virtue of the branched pipe through the water inlet. According to the multifunctional slow-release fertilizer applicator, integrated fertilizer-water fertigation can be carried out by virtue of soluble solid fertilizers, so that the fertilizer is rapidly, stably and efficiently applied; furthermore, the structure is simple, and the operation is convenient.

The present invention relates to the technical field of agricultural machinery, in particular to a self-propelled side fertilizer applicator and its working method. The frame is also provided with a ditching and fertilizing device connected to the power unit in transmission, and the ditching and fertilizing device is used to plan the soil to form a ditch and fertilize the ditch, and the ditching and fertilizing device is arranged on the Walk on the side of the chassis in the direction of travel. In the fertilizer applicator of the present invention, the walking chassis walks among the crop forests. During the walking process of the walking chassis, the ditching and fertilizing device ditches the soil below and puts in fertilizers, so as to realize the fertilization operation. On the side of the chassis in the direction of travel, it is possible to fertilize directly under mulberry, fruit, tea and other trees to ensure a good fertilization effect; furthermore, it also avoids the compaction of the fertilization cover soil by the walking chassis to further ensure the quality of fertilization.

The invention discloses a mechanical fertilizer ratio variable fertilizer distributor and an implementation method thereof. The fertilizer distributor includes a fertilizer box, a motor, rotating blades, a coupling, a fertilizer mixing box, a fertilizer distributing auger, a fertilizer distributing opening, a regulating valve plate, multiple partition plates and multiple fertilizer inlets; a hollow cylinder is arranged in the middle of the fertilizer box, and a motor is installed in the hollow cylinder; the partition plates are arranged in the fertilizer box, and divide the fertilizer box intomultiple sub-boxes; the regulating valve plate is composed of multiple rotating parts with the same number as the fertilizer inlets, and the rotating parts can rotate along the hollow cylinder so asto adjust the size of the fertilizer inlets; the fertilizer mixing box is internally provided with the rotating blades and the fertilizer distributing auger, and the fertilizer distributing auger is connected with an output shaft of the motor through the coupling. Accordingly, the regulating valve plate can be rotated in the horizontal direction according to the change of the soil nutrient, the size of the fertilizer inlets is adjusted, and then the fertilizer formula is adjusted, and the problems that the soil nutrient is out of balance, and the fertilization precision is insufficient are solved.

The invention relates to an agricultural ultrasonic atomization spraying device. The agricultural ultrasonic atomization spraying device comprises a sprayer barrel body for containing pesticide liquid and a closed device, wherein one or more ultrasonic atomizers capable of atomizing pesticide liquid are arranged in the closed device, a pesticide inlet, an air inlet and a mist outlet are formed in the closed device, the pesticide medicine inlet is connected with the barrel body, an air blower for blowing air in is connected to the air inlet through an air inlet pipe, the mist outlet is connected with a spraying pipe, and a sprayer nozzle for spraying vaporific pesticide liquid is arranged on an end opening of the spraying pipe. The surface of the liquid is swollen through ultrasonic directional pressure intensity, cavatition happens around the swollen liquid surface, the liquid is atomized into small molecule aerial fog, and therefore water molecules can directly act on the surfaces of crops through the aerial fog, spraying or fertilizer application or insect killing can be performed on the crops more effectively, water, pesticide, fertilizer and the like are saved, and the food safety problem caused by uneven pesticide spraying is prevented.
