A seed delivery system for use in a seeding or planting machine that removes the seed from a seed meter by capturing the seed therefrom. The delivery system then moves the seed down to a lower discharge point and accelerates the seed horizontally rearward to a speed approximately equal to the forward travel speed of the seeding machine such that the seed, when discharged has a low or zero horizontal velocity relative to the ground. Rolling of the seed in the trench is thus reduced. Furthermore, as the seed only has a short drop from the outlet to the bottom of the seed trench, the seed has little vertical speed to induce bounce. The delivery system uses a brush belt to capture, move and accelerate the seed. By capturing the seed and moving it from the meter to the discharge, the seed is held in place relative to other seeds and the planter row unit. As a result, the seeds are isolated from row unit dynamics thereby maintaining seed spacing.

A row crop unit for use in an agricultural seeder includes a furrow opener for opening a furrow in the soil, a seed metering system for metering seed to be placed in the furrow, and a seed placement system for placing seeds in the furrow. The seed placement system and the seed metering system are in communication with each other and at least in part define a seed travel path associated with the furrow. A furrow closer covers the seed in the furrow with soil. A seed temperature conditioner is associated with the seed travel path for varying a temperature of seed traveling through the seed travel path. A temperature sensitive sensor is positioned to sense seed which has been deposited in the furrow between the furrow opener and the furrow closer. An optional packaging tube holds a temperature sensor or sensor array. A lens is mounted with the same tube. A larger diameter tube may be positioned around the sensor packaging tube. A positive air pressure/air flow may be introduced between the two tubes. This positive air-flow forms a positive pressure and/or air flow barrier to push dust away from the sensor lens or sensor surface.

The invention discloses a corn planting and cultivating method. The corn planting and cultivating method includes the following steps of selecting a corn variety and conducting soil preparation before planting, arranging wide rows and narrow rows at intervals, sowing corn, completing sowing, pipe paving, film paving and soil covering through an air suction type precision seeder, and conducting field management in the seedling stage, the ear stage and the flower stage, wherein the width of each wide row ranges from 85cm to 95cm, the width of each narrow row ranges from 25cm to 35cm, a drip irrigation zone is paved in the middle of each narrow row. According to the corn planting and cultivating method, due to the fact that the method that the wide rows and the narrow rows are arranged at intervals is adopted, the number of drip lines which are used can be lowered. Modifiers are sprayed in the early period of the field management in the seedling stage to control the plant height and the ear position, and the defect that through a conventional planting method, the corn easily falls over due to the fact that the plant height is large and the ear position is high is overcome. Pesticide is sprayed through a self-propelled high-stalk crop boom sprayer in the middle and later period of management to control pests, the influences of natural disasters on corn growth are reduced, and the influences on productivity caused by a large number of European corn borers, cotton bollworms, aphids, leafhoppers and red spiders appearing after corn jointing are eliminated.

An agricultural planter having sensors for measuring multiple soil properties adjusts planting depth and seeding rate in real time based on the measured soil properties. An optical module is carried by the planter for collecting soil reflectance data. A pair of soil contact blades protrude from or are embedded in the optical module for collecting soil EC data and soil moisture data. A switching circuit or phase lock loop allows the same soil contact blades to feed signals to both a soil EC signal conditioning circuit and a soil moisture signal conditioning circuit. The soil moisture data can be used to calibrate the soil EC data and the soil reflectance data to compensate for effects of changing soil moisture conditions across a field. The sensor module can be positioned behind a seed tube and used as a seed firmer, or incorporated into a seed tube guard.

A no-till drill with a novel walking beam assembly that allows the drill to be pulled over severe terrain conditions that include large rocks, fallen limbs and other large obstructions. The inventive walking beam assembly includes two independent pivot points that allow the cutting and opening disks to maintain substantially constant or continuous contact with the ground, such that the length of the furrow formed and seed deposited therein are maximized. A closing disk assembly is suspended from the rear of the drill independently from the walking beam assembly. This independent suspension allows the walking beam assembly to function without interference from the closing disks.
