In the process of growing crops, if reasonable fertilization can be achieved, both the high quality and high yield of crops can be achieved, and fertilizer can be saved. So, how can we correctly determine the lack of fertilizer in crops? 1. Sentencing of crop nitrogen deficiency fertilizers. The main manifestations of nitrogen deficiency in crops are: thin and short shoots, small upright leaves, grayish green color, petiole, veins, and surface reddening; small fruit, early fruits, easy shedding, imperfect root development, and fine roots , big roots, new roots yellow. 2. The determination of phosphate deficiency in crops. The main performance of crops in phosphate-deficient fertilizers is relatively complex, and their performance varies from crop to crop. When the corn lacks phosphate fertilizer, it will show slow growth at the seedling stage, symptoms after 5 leaves are more obvious, the leaves are purple, and the grain is not full. When wheat is deficient in phosphate fertilizer, it is characterized by slow growth of seedlings, poor root development, and reduced tillering. The base of the stem is purple, and the leaves are dark green, purplish, and small in number. 3, determine the lack of potassium fertilizer crops. In the absence of potassium fertilizer in crops, the tip of the lower leaves will yellow at first and gradually yellow along the edge of the leaves, but the veins on both sides of the leaves and the midribs will still maintain the original green color. When severe, it will gradually develop upwards from the lower leaves, eventually causing most of the leaves to yellow and the edges of the leaves to be fiery. Cereal crops will result in weakening of tillering power, short internodes, weak and sagging leaves, and soft and easy lodging of stems. The dicotyledonous plants will cause the leaves to curl, gradually shrink, and sometimes the leaves will be incomplete, but the middle of the leaves will remain green. Root crops cause root weight to decline and quality is poor.
A mixture of Cosmetic Raw Materials, which is made up of various raw materials after reasonable dispensing. Cosmetics have various kinds of raw materials and different properties. According to the properties and uses of cosmetics, they can be broadly divided into two categories: matrix materials and auxiliary materials. The former is a kind of main raw material of cosmetics, which occupies a large proportion in cosmetics formula and plays a major role in cosmetics. The latter plays a role in shaping, stabilizing or giving color, fragrance and other characteristics of cosmetics, which are not used in cosmetic formulations, but are extremely important. Cosmetics are made from natural, synthetic or extracted substances with different functions as raw materials by heating, stirring and emulsifying processes.
The main raw materials of cosmetics are commonly used as matrix materials and natural Additives. The general base materials for cosmetics include: oily raw materials, which are the most widely used raw materials for cosmetics, play a protective, moisturizing and softening role in skin care products, play a stereotyping and aesthetic role in the use of products; surfactants, which can reduce the surface tension of water, with decontamination, wetting, dispersion, foaming, emulsification, thickening. Other functions, known as industrial monosodium glutamate, moisturizing agents and essential ingredients for cream cosmetics, are used to prevent dry and cracked paste and keep skin moisture. Adhesives are mainly used for hair gel, mousse and gelatin mask. Powder is mainly used for making powder products, and pigments and dyestuffs are mainly used for cosmetic modification. Products; preservatives, antioxidants, in the cosmetics shelf-life and consumer use in the process of inhibiting microbial growth; perfumes, increase cosmetic fragrance, improve product value; other raw materials, including UV absorbers, dye intermediates used for dyeing black hair, perm raw materials, antiperspirant, deodorant, anti-dry skin crack Raw materials, anti acne raw materials, etc. Common natural additives are hydrolyzed gelatin, hyaluronic acid, superoxide dismutase (SOD), Royal jelly, silk fibroin, mink oil, pearls, aloe vera, malt meal stone, organic germanium, pollen, alginic acid, seabuckthorn, Chinese herbal medicine and so on.
