The spring peanuts flowering period is the transformation period from vegetative growth to reproductive growth of peanuts. The following three points should be grasped in management.
First, cultivator soil. Combine the cultivating peanuts to meet the needle soil with the cultivator, use the hoe to break the top soil layer, and stack the fine soil on the peanut roots, which will help the peanuts to form effective needles. Through cultivating and cultivating, the soil layer can be loosened and the permeability is good, and it is also conducive to lowering the flower needles, increasing the fruit setting rate of the individual plants, thereby increasing the output of the peanuts. In the cultivator, we must remove the weeds from the ridges and peanut seedlings from the roots in order to reduce the conflict between weeds and peanuts, and promote the robust growth of peanut plants, and lay down the high yield skeleton.
Second, water and fertilizer. The flower needle is very sensitive to moisture before entering the soil. If the soil moisture is poor or the rainfall is insufficient, it is necessary to replenish the water promptly. The flowering period is the period from vegetative growth to reproductive growth. It is also a time when peanuts are relatively prosperous and sensitive to fertilizers. In particular, sandy lands with poor water-retaining fertility must be top-dressed in a timely manner. In combination with watering acres, 20 kg of nitrogen and potassium fertilizers are topdressed.
Third, disease prevention and pest control. The common pests in production include aphids, cotton bollworms, and red spiders. Aphids can be sprayed with imidacloprid pesticides, and the second and third generations of cotton bollworms are often transferred to peanut fields for harm. They can be sprayed with insecticides such as lambda-cyhalothrin. High temperature and dry weather can often lead to the occurrence of spider mites, and can be controlled by special agents such as peony or broom net. The time of medication should be selected from 6 to 8 am or 4 to 6 pm. Stalk rot and root rot are common diseases in early stage of peanuts. We must follow the principle of "prevention first," and always do a good job of careful management to improve the disease resistance of plants. Use 50% carbendazim WP 800 times, or 70% thiophanate-methyl wettable powder spray prevention, spray once every 7 days, have better control effect.
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.
