Sputum deficiency

The first symptom is that the nitrogen-deficient plants grow slowly, the stalks are thin, the leaves are narrow, the leaves are yellow, the roots are thin and the roots are thin, the birth is delayed, the grains are small, the quality of the rice is poor, and the yield is reduced. The second is that the leaves of P-deficit plants are narrow, dark green, and the number of flowers is decreased, and the flowering and solidification is late or delayed. The root development is not good, and it is rarely and short, and the plant growth slows down, resulting in late culturing. Third, the center of the potassium-deficient sorghum leaf is dark green, and there is partial yellowing or necrosis at the tip and leaf margin. The yellowing and necrosis parts have clear boundaries with the healthy part, and the leaves are wrinkled. The fourth is the lack of manganese sorghum Mn-deficient plant growth is slow, there is a clear chlorosis, red-brown pigment ribbons between veins. The fifth is the yellowing between the sulfur-deficient veins, and the redness of the stem base in late autumn, which gradually spreads along the leaf margin to the whole leaf. Sixth, the lower leaf of the iron deficiency becomes brown, and the stems and leaf sheaths turn reddish purple, and the newly grown leaves show chlorosis.

Prevention and control methods Sorghum needs potassium to be higher than nitrogen and phosphorus. The sorghum fertilization method includes base fertilizer, seed fertilizer and topdressing fertilizer. Basal fertilizers often account for 80% of total fertilization. In recent years, we have promoted the use of compost and bio-organic fertilizers made from enzymes. Basal fertilizer should be dominated by organic fertilizer and phosphate fertilizer, with appropriate application of nitrogen fertilizer, application amount per 667m2 pig manure urine 1000kg, superphosphate 25kg, ammonium phosphate 10kg, using the application or hole. Poor or weak plots can be applied urine rope 3-4kg, pig manure 1500kg. Top dressings are mainly applied in two applications of panicle fertilizer and granule fertilizer. The first time in the first 6 months after sowing 6-8 leaves, 667h2 application of urea 10kg; the second time before heading 7-14 days, apply urea 5-8kg. In addition, we advocate the use of Huimanfeng, Fengbao, double-effect micro-fertilizer, “Yiyi” microbial organic fertilizer, Nongyiqing liquid fertilizer, Chuanfeng brand high-efficiency Amino Acid liquid fertilizer, and agricultural active organic fertilizer.

Standardized Herbal Extract

A standardized herbal extract is an herb extract that has one or more components present in a specific, guaranteed amount, usually expressed as a percentage. The intention behind the standardization of herbs is to guarantee that the consumer is getting a product in which the chemistry is consistent from batch to batch. This practice has developed out of the drug model of herbal medicine, in which modern scientists have attempted to identify the components of a plant that have definite pharmacological activity in the body. Unfortunately, while scientists can isolate many constituents from an herb and discover how particular chemicals may act in the body, they inadvertently remove or overlook components that may contribute to the activity of the whole herb. Consequently, standardization may concentrate one constituent at the expense of other potentially important ones, while changing the natural balance of the herb`s components.
