Due to less fiber, lighter spicy flavor and more meat, the big fat ginger is suitable for processing and has a large market demand. The price is good in recent years. Introduced cultivation techniques are as follows:
1. Selecting and Introducing Seeds: At present, the ginger seeds are planted in a variety of varieties. As far as possible, the roots are clustered, short and hypertrophic, with less fibers and lighter flavors. The ginger and bamboo ginger are removed, and the varieties are as pure as possible. As far as possible in the field to choose the most vigorous growth, high yield per plant ginger. In order to maintain purity, at the same time, there is no ginger block that is not frozen, does not shrink, does not change its color, and is not easily peeled off from the epidermis. At the same time, there is no ginger, which does not suffer from cold, does not shrink, does not change its color, and is not easily peeled off from the epidermis. Ginger plant growth is weak, ginger is small and often damaged by ginger borer, not suitable for planting.
2. Soaking and disinfecting: In late February, choose a sunny day and turn the ginger over the sun for 1-2 days. Place it in the room for 2-3 days. The ginger stack covers the straw and promotes nutrient decomposition. Usually after 2-3 times ginger and distressed ginger, the ginger block is selected to be hypertrophic, plump, bright and shiny, with fresh flesh, not rotted, unfrozen and healthy ginger seeds, and 100 times 40% formalin. Solution or 20% thiophenanthe (Loncobacter) soaking seeds for 10-20 minutes, after the heap of Kai, cover germination, after 10 days, protect 1-2 fat buds. The larger the ginger seed, the stronger the shoots, and the higher the yield.
3, scientific selection of land, sufficient base fertilizer
Ginger is warm and tolerant to yin. It is advisable to choose slightly shaded mountain pit fields, which are sandy and fertile. The soil is deep loam, and the sewage is convenient. Afternoon sunshine is shielded. The land preparation and production lime 60 kg lime, 畦 1-1.2 meters, groove width 30cm, ditch depth 20cm, after the whole squat, the sorghum open 10cm second row of planting ditch, row spacing 40-50cm, while applying basal 30-40 Tam, Cake fat 100kg, compound fertilizer 50kg, potassium sulfate 50kg, borax 1-1.5kg, zinc fertilizer 3-4kg, magnesium fertilizer 10kg.
4, in the right kind, close planting.
Generally covered with plastic film, can be in the "spring equinox" to "clear and bright" under the kind of solar terms. 4000-6000 acres of planting, ginger placed in the middle of fertilization, plant spacing 15-20cm, when the next species bud head up, unified south, in order to dig out ginger. After sowing, cover the 2-3cm with 50 soil-fertilizer and cover the mulch. (If not covered with plastic film, cover the straw).
5, a reasonable fertilization, soil watering.
Grasp the early light and heavy equipment, apply heavy fertilizer, apply fertilizer to the fall, about 3 leaves after shoots, apply fertilizer when starting the branch, use mainly available nitrogen fertilizer, and after the second time in the “early autumnâ€, every 15 Once a day, continuous 2-3 times, mainly potassium sulfate compound fertilizer. Combine fertilizing and weeding the soil 4-5 times to ensure that the ginger block does not appear on the surface. In the aspect of water pipes, keep the soil moist after emergence, and use the principle of not whitening the topsoil, watering or gushing horse water, and often watering after the beginning of autumn, before dusk or 8 o'clock in the morning, prevent water accumulation, and generally harvest in late September. The quality is good and the ginger is delayed until December.
6. Pest control.
Insect pests are mainly ginger borers and ground tigers, which can be sprayed with Miao esters of Avignon species or poisonous soils. The disease is mainly Jiangyan, which can be used to kill poisonous mites. Bacteria, chlorothalonil, Baitai, etc.
Cosmetics are compound mixtures made from various raw materials after reasonable blending and processing. There are many types of cosmetics raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: base raw materials and auxiliary raw materials. The former is a main raw material of cosmetics, which occupies a large proportion in cosmetic formulations, and is the main functional substance in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other characteristics to cosmetics. These substances are not used in large amounts in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production processes such as heating, stirring and emulsification.
