The first is to pick sunny harvest before and after the summer heat (August).
The second is that the lily used for storage must be fully mature, with low moisture content, no disease, no insects, and no damage. When removing the squash, remove the stalks, remove the filth, remove the fibrous roots, gently remove the fibrous roots, place them gently, grade the baskets, shading them in time, return them indoors, and prevent them from being exposed to the sun in the field so that the outer scales will not turn red and dry. The deterioration of quality affects the germination rate.
The third is to choose the mother bulbs hypertrophy, uniform uniformity, color white, close cohesion, roots robust, top flat and round, gargle intact, disease-free pest-free, no smell, no rotten tablets, more roots and thick, sub-bag It is clear that the bulbs with three or four seed bulbs per bulb are used for seeding, and the unrooted bulbs should not be reserved for species use.
Fourth, the bulbs are treated with medicaments. 500-fold solution of chlorothalonil and 1500-fold solution of diclofenac EC is used for soaking for 20 minutes to 30 minutes, and can be stored after drying. Store the place to master the principles of “dryness, ventilation, shade, shadingâ€. Choose an empty room and fumigate with 0.3% formaldehyde and potassium permanganate once. Do not place the bulb on concrete floor.
The fifth is to adopt the pile-up method and spread a layer of clean loam (hand-rolled into groups, hand-to-ground, loose-lying) or dry fine river sand on the ground with a layer of 7cm thick. Generally, it can be piled three or four layers. The first layer is rooted down and arranged. Neatly, cover with a layer of earth or sand about 4 cm thick, and put a layer of lilies on it, with the roots facing upwards, then cover with a layer of earth or sand, and so on. It is advisable to cover the thickness of the soil or sand to prevent the lily from appearing. Surrounded by earth or sand, it can be stored until the following spring. During the storage of the lily, a wet and dry thermometer is attached to the storage room to control temperature and humidity and improve ventilation conditions. Check once every 20 days to 30 days, should not be too much turning, such as the discovery of necrotic decayed lily bulbs, should be promptly removed.
A roundness tester is a measuring tool that uses the rotation axis method to measure the roundness error of a workpiece. The roundness tester is divided into sensor rotary and workbench rotary. During measurement, the measured part is installed concentric with the precision shaft system, and the precision shaft is equipped with an inductive length sensor or workbench for precise circular motion. The roundness meter consists of an instrument's sensor, amplifier, filter, and output device. If the instrument is equipped with a computer, the computer is also included in this system.
A roundness tester is a precision instrument used to measure the out-of-roundness of a rotating surface (shaft, hole, or spherical surface) of a component. There are usually two types: small desktop, where the workpiece is mounted on a rotating workbench and the measuring head is mounted on a fixed column; and Large floor mounted, with the workpiece installed on a fixed workbench and the measuring head installed on the rotating spindle. During measurement, the measuring head contacts the workpiece's surface, and the instrument's rotating part (workbench or spindle) rotates for one cycle. Due to the extremely high accuracy of the supporting bearings in the rotating part, the measuring head will generate a high-precision circular trajectory on the measured surface during rotation. The out-of-roundness of the measured surface causes the measuring head to shift and transform into an electrical (or pneumatic) signal. After amplification, it can be automatically recorded on a circular recording paper, and the out-of-roundness of each part can be directly read out for accuracy evaluation and process analysis and widely used in precision bearings, machine tools, and instrument manufacturing industries.
The Roundness Testeradopts a radius measurement method and operates in a rotating manner. The rotation axis system of the roundness meter adopts a high-precision air floating spindle as the measurement reference; The electrical part of the roundness tester is composed of advanced computers, precision circular grating sensors, and precision inductance displacement sensors. The circular grating sensors and precision inductance displacement sensors measure angle and radial displacement, ensuring the accuracy of measuring the angular displacement and radial value of the workpiece; The roundness meter measurement software adopts a roundness measurement software based on the Chinese version of WinXP operating system platform, completing data collection, processing, and measurement data management.
