A special artificial pollination device and method for tomatoes

Abstract

The invention discloses a special artificial pollination device and method for tomatoes. The device includes a "concave"-shaped contact and an outer cylinder with a hollow structure; C"-shaped clamping part, which is clamped at the bottom of a spike flower, that is, the "wrist" part, the built-in soft iron and permanent magnetic sheet on the "concave"-shaped contact are oppositely arranged, and the outer cylinder is sleeved with a liquid storage tube and an engaging type driving mechanism, a battery box and a battery box upper cover for fastening with the battery box are provided at the end port of the outer cylinder, and a battery and two time relays are arranged in the battery box, so that the battery, time relay, wires and built-in soft Ferroelectric connection, and the direction of movement of the piston and the rack is controlled by an electromagnetic control switch and a bidirectional switch. The "C"-shaped clamping part of the present invention directly acts on the "wrist" part instead of the receptacle or style, and acts on one panicle at a time, which not only improves the work efficiency, but also avoids the occurrence of diseases under the premise of eliminating phytotoxicity.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, and relates to a pollination device, in particular to a special artificial pollination device and method for tomatoes. Background technique [0002] Tomato flowers are hermaphroditic flowers, with both pistils and stamens on one flower, and are self-pollinating plants. But in fact, the pollination of tomatoes is not easy. There are two reasons: one is that the stigmas of tomato petals are hidden inside, and insects are not easy to pollinate; the other is that although tomato flowers are hermaphrodite flowers, the flowers themselves do not contain honey , without honey, bees do not like to pollinate tomatoes, especially in winter stubble crops. In open field cultivation conditions, artificial pollination is generally not required. Under the cultivation conditions of protected areas in winter and spring, due to poor ventilation and less insects in the shed, it is not conducive to p...

AI Technical Summary

Problems solved by technology

[0004] (1) Inaccurate concentration measurement: inaccurate dilution concentration, uneven liquid medicine, prone to phytotoxicity, low seed setting rate, long puffing time (more than 7 days), deformed fruit and severe cracking phenomenon, etc.;

[0005] (2) The operating tools are unscientific: the operation is unstable, and due to the defects of the tools, no matter whether it is applied or applied, there are drops of medicinal liquid left on hands, especially on flowers, leaves, and branches, resulting in waste and improving cost, pollute the environment, harm plants, and cause wilting or necrosis of the affected parts;

[0006] (3) The effect of spotting is poor: use a brush or other similar tools to spot and smear, the size of the droplets is not controlled, the smearing is uneven, and the droplet-shaped droplets are not easy to cover the entire style stigma, and it is easy to slip and roll on the plant, and it is not easy to stick Attached, resulting in poor absorption, repeated flowering will cause cracking or even failure

[0007] (4) Disadvantages of flower spraying: the speed of flower spraying is faster than that of spot flower, but the drug effect is slow and the expansion rate is low

[0008] (5) The small environment is not suitable
