Mung bean cultivation points
Cultivation points:
(1) Land preparation. Mung bean is a deep-rooted crop, and cotyledon hypertrophy, strict requirements for site preparation, sowing should be deep plowing, fine smashing, to achieve the Panasonic real, the same depth, otherwise it will affect the emergence.
(2) Fertilization. Before planting, one mu of farmhouse manure should be used for 2500-3500kg and superphosphate about 10kg. If fertilizing can not be done before sowing, appropriate amount of nitrogen and phosphate fertilizer can be applied in the early stage of growth to enhance the nitrogen fixation of root nodules.
(3) sowing. Before sowing, select the sunny day and spread the seeds thinly on the mat for 1 to 2 days to promote germination and emergence. The sowing method is based on seeding, with a spacing of about 40 cm, a seeding rate of 1 to 1.5 kg per mu, and a seeding depth of 3 to 5 cm. If the soil moisture is poor after sowing, it can be suppressed once.
(4) Management. One, Dingmiao. When the seedlings grow out of two leaves and one heart, they remove the “seedlingsâ€, and when the four true leaves are set, the seedlings will be planted with 1 to 125,000 plants per mu. When the two leaves are in one heart, a shallow cultivator is performed to remove the compaction, eradicate the weeds, and enhance the ability of nodules to move. When the four-leaf is combined with the cultivating cultivator for the second time, the cultivating is carried out for the third time in the five to six-leaf clumps, and the cultivars are again culled once the heads have been put out and the arrows are dragged. The husks are completely removed; Top dressing, timely removal of water in the rainy season, so that the soil is often in a loose, moist state, to ensure the normal growth of plants; 4 control of pests and diseases. In recent years, pests and diseases that harm mung bean mainly include leaf spot, ticks, aphids, and soybean meal. To prevent mung bean leaf spot, spray with 40% carbendazim gel 1000 times solution at the early stage of the disease, and use 90% crystals of trichlorfon for bait and kill, and 40% omethoate with 1000 times liquid to kill. The use of 40% isopropylphosphonate or 50% killer pine 1000 times liquid sprayed when the adult was sprayed, have good results.
The image measuring instrument is based on CCD digital image, relying on the powerful software capabilities of computer screen measurement technology and spatial geometry operation. After installing the special control and graphic measurement software, the computer becomes the measurement brain with the soul of the software and is the main body of the whole equipment. It can quickly read the displacement value of the optical ruler, and obtain the desired result instantly through the software module operation based on the spatial geometry; A graph is generated on the screen for the operator to compare the image with the image, so that the possible deviation of the measurement results can be identified intuitively.
Image measuring instrument is a high-precision optical image measuring instrument composed of high-resolution CCD color lens, continuous zoom objective, color display, video crosshair display, precision grating ruler, multi-function data processor, data measuring software and high-precision workbench structure.
The instrument is applicable to all application fields for the purpose of two-dimensional plane measurement. These fields include: machinery, electronics, molds, injection molding, hardware, rubber, low-voltage electrical appliances, magnetic materials, precision hardware, precision stamping, connectors, connectors, terminals, mobile phones, home appliances, computers (computers), liquid crystal television (LCD), printed circuit boards (circuit boards, PCBs), automobiles, medical devices, clocks, screws, springs, instruments, gears, cams, threads, radius templates, thread templates Wire and cable, cutter, bearing, screen, test screen, cement screen, screen plate (steel mesh, SMT template), etc.
