Summer corn field management

At present, summer corn field management should mainly do the following work.

1. Pursue the jointing and strong stalk fertilizer and master the amount of fertilizer according to the seedling condition and soil condition. Usually 10-15 kg of urea per mu, 30-40 kg of superphosphate, 10-15 kg of potassium chloride, and 1-1.5 kg of compound micro-fertilizer. If the drought is heavier, fertilize or water after fertilization, adjust the fertilizer with water, promote fertilizer with water, and lower the soil temperature, which is conducive to ear differentiation. It is required to finish the top dressing in early August, and carry out the top dressing with vitality or urea plus potassium dihydrogen phosphate.

2, chemical control, anti-fall application of corn, can increase the plant height of corn by 20-30 cm, control up, make the stalks thick, roots increase, thereby increasing corn yield and preventing lodging. In the corn big bell period, 6-7 days before the tasseling, 10 ml (1) of corn is used to spray 30-40 kg of water per acre.

3, prevention and control of pests This year's climatic conditions suitable for corn borer, should be controlled with carbofuran or ethyl enemies. In recent years, summer maize large and small leaf spot disease is on the rise, and it must be prevented early. In the first ten days of August, it will be sprayed with 1000 times of mancozeb, and it will be prevented once every 6-8 days, and it will be prevented 2-3 times.

4, clear ditch, summer corn is afraid of drought, and is not resistant to waterlogging. Undigging fields should be immediately trenched, and the blocked and blocked trenches should be quickly cleaned up, and the “three trenches” should be deepened and widened to ensure that the trenches are connected and unobstructed. Carry out cultivating and weeding, and cultivate the roots.

Manual Video Measuring Instrument

Manual image measuring instrument is a precision measurement instrument that uses manual driving for 3 axes, and the measurement software is manual point taking.

This instrument uses a zoom objective to magnify the measured object, and the image is input into a computer through a CCD industrial camera device. The enlarged image of the measured object is transmitted to the measurement software for non-contact and efficient geometric measurement of various complex workpieces.

Suitable for non-contact measurement of stamped parts, plastic parts, thin film shaped, easily deformed, easily damaged, and small-sized workpieces, such as workpiece measurement in industries such as rubber, plastic, small hardware, clocks, and light industry.Video Device

.

The manual image measuring instrument consists of three parts: an image acquisition device, a data acquisition device, and a two-dimensional measurement software. The zoom objective lens and high-resolution color camera form an image acquisition device, and the data acquisition device is composed of a grating ruler and a data processor. The image and data are measured using 2D measurement software to achieve point, line, arc, and distance measurements.
