Summer sowing carrot high yield cultivation points
In recent years, the growing area of ​​carrots in Dingzhou City has been stable, and the core area of ​​pollution-free carrot cultivation has been formed with Da Zuli as the core. The carrot industry has become the leading industry for the increase of local vegetable farmers. The experience of the high-yield cultivation techniques for summer sowing carrots in Dingzhou is summarized below for your reference. First, choose the best species. Choosing the right variety is the key to increase production and increase production. Production shows that South Korea's dry red hundred days, Thailand's Hongxiu, Japan's Kuroda five inches, red ginseng six inches and other varieties, with high yield, good quality, resistance Strong disease characteristics, suitable for planting. Second, the appropriate sowing. In the south-central region of China, a suitable sowing date is in mid-late July. There are two kinds of sowing methods: seeding and sowing. Seedlings emerged during the high temperature and dry season, the temperature is not suitable for carrot seed germination and seedling growth, the seedling rate is lower than in spring, so the seeding rate should be properly increased, sowing rate per acre of 250 to 300 grams. After sowing, it is covered with straw or other straws. If there are conditions, it is best to use shading nets to shade the shades. The shading nets are required to be about one meter from the ground. For the plots with insufficient shade cover after sowing, the seeding rate needs to be increased appropriately. Third, and time seedlings, strengthen the cultivator. Throughout the growing period, the carrots need to be twice thinned, the first time the thinning is between 1 and 2 true leaves, and then shallow, prompting the seedlings to grow. When the second time the seedlings were in 3 to 4 true leaves, the seedlings were used to establish the seedlings. The distance between the small and medium sized cultivars was 10 cm, the spacing between large cultivars was 13-15 cm, and the cultivators were cultivated. Fourth, scientific management of fertilizer. There should be no water shortage during the seedling period. Keeping the soil moist and overdrying and over-wetting are not conducive to seed germination and emergence. Fertilizers should be topdressed for 2 to 3 times. The first topdressing will be carried out during the groundbreak of carrots. In combination with watering, the mu chase acquaintances will have 1,000 kg of excrement or 20 kg of urea. After 20 days, the second or third fertilizer will be followed. Each time topdressing 15 to 20 kg of urea, and appropriate additional small amount of potash. Into the vigorous growth of leaves, should be appropriate water control to prevent leggy. The root enlargement period of meat is the period when the root growth of the fleshy root is the fastest, and the demand for water is the most. The water supply should be satisfied in time and the small water should be poured. Late attention should be paid to water control, tumor roots.
A spectrometer is a scientific instrument used to separate and measure spectral components of a physical phenomenon. Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed. In visible light a spectrometer can separate white light and measure individual narrow bands of color, called a spectrum. A mass spectrometer measures the spectrum of the masses of the atoms or molecules present in a gas. The first spectrometers were used to split light into an array of separate colors. Spectrometers were developed in early studies of physics, astronomy, and chemistry. The capability of spectroscopy to determine chemical composition drove its advancement and continues to be one of its primary uses. Spectrometers are used in astronomy to analyze the chemical composition of stars and planets, and spectrometers gather data on the origin of the universe.
Examples of spectrometers are devices that separate particles, atoms, and molecules by their mass, momentum, or energy. These types of spectrometers are used in chemical analysis and particle physics.
