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.

First, early application of base fertilizer. The fruit consumes a large amount of nutrients during the growing season, and it is urgent to supplement the nutrients after harvesting the fruit to restore the tree potential. At the same time, the roots of pear trees entered the second growth peak from September to November. At this time, fertilization is beneficial to the rapid decomposition of fertilizers and to the absorption and storage of nutrients by new roots. Fertilization should be based on organic fertilizer, appropriate amount of nitrogen, phosphorus, potassium quick-acting fertilizer, combined with tree potential and the amount of results to determine the amount of fertilizer, this time the application of base fertilizer should account for 40% of the annual fertilization. Generally, 1,500 to 3,000 kilograms of manure, human excrement, poultry waste or decomposed wheat bran, wheat straw, weeds and other organic fertilizers are applied per mu, and 40-50 kg of NPK fertilizer is mixed. Method: Dig into the ditch about 1 meter from the trunk, the tree can be close to a little; the fertilization ditch is about 40 cm deep, about 30 cm wide, and shallow inside and outside. After fertilization, mix well with the backfill to avoid burning roots due to accumulation of fertilizer. The second is the top dressing. In September and October, the root garden can be topdressed again. Spray 0.1% to 0.3% urea plus 0.3% to 0.5% potassium dihydrogen phosphate mixture. Spray the leaves on the morning and evening after the dew is dry. Evenly and thoughtfully, avoid high temperature spraying at noon to avoid harm.
When is the apple orchard?
The fertilization time should be selected before the fall of the fruit harvest in the autumn, and the fertilization should be based on farmyard manure, and a small amount of nitrogen fertilizer should be added as well. Because the ground temperature is high at this time, the fertilizer is decomposed quickly, and the fruit trees have not yet fallen leaves, which is conducive to the accumulation of nutrients in the fruit trees and the supply of the tree in the next year. The roots of apple trees are strong. When fertilizing, the distribution of roots should be seen. Generally, it is applied to the roots of the roots of the canopy. This is conducive to the outward expansion of the roots of the fruit trees and enlarge the absorption area. The fertilization site is within the projection range of the canopy, the depth of the trench is not less than 40 cm, the width is 30 to 40 cm, the length depends on the size of the tree, 40 to 80 cm below 6 years, and about 1 meter above 6 years old. On both sides of the tree, it was dug in the north and south sides of the tree and excavated to the outside of the original fertilization ditch every year. In general, the apple orchard is applied with 3,000 to 5,000 kg of organic fertilizer per acre.
Why do apples spray foliar fertilizer after harvest?
Increasing the photosynthetic efficiency of leaves by spraying foliar fertilizer is an important aspect of fruit tree management after harvesting. In the process of spraying foliar fertilizer after apple picking, a large number of elements and medium and trace elements need to be replenished. The symptoms of zinc deficiency and iron deficiency in fruit trees are due to the accumulation of too little nutrients in the previous year, while the second year fruit trees are sprouting. In the process, the original accumulation of nutrients will soon be exhausted. In the process of spraying the leaf surface fertilizer, the fruit farmers should pay attention to the front and back surfaces.
