Vitamin d deficiency, calcium and phosphorus metabolism disorders in geese
Vitamin D (VD) deficiency or calcium and phosphorus deficiency as well as calcium and phosphating disorders can cause osteoporosis, rickets in young geese or osteomalacia in adult geese. The disease is a nutritional bone disease, which can occur in geese of different ages. Clinically, it is often found in 3-week-old goslings. The main manifestations are growth stagnation, bone deformation, limb weakness, soft feet and paralysis. When the adult goose is sick, the number of eggs is reduced or soft-shell eggs are laid. In addition, the disease can also induce other diseases, often causing certain economic losses to the goose industry. 1. Disease

How to improve the effect of applying phosphate fertilizer in newly reclaimed red soil? Is it feasible to apply high amount of phosphorus in phosphorus-deficient soil?
The newly reclaimed land of red soil contains low total phosphorus (generally less than 0.4 g / kg), high content of iron and aluminum, and the main phosphorus in the soil is iron phosphate and aluminum compounds, which is not easy to be absorbed and utilized by crops. Therefore, when planting crops and economic trees in newly reclaimed fields in red soil, it is necessary to emphasize the application of phosphorus.

How to prevent and cure rice seedling shrinkage disease
The main causes of rice seedling shrinkage are: phosphorus deficiency, zinc deficiency and saline-alkali injury. The main control methods are as follows: first, phosphorus deficiency generally occurs in the powder-tillering stage after slow seedling growth, the plant is short, the leaf shape is slender and erect, the leaf color is dark green, the top of the leaf cluster is neat, the leaf pillow distance is significantly shortened, the powder tiller, the leaf tip is red, and the old leaves are reddish and even die. The main causes are (1) lack of available phosphorus in soil, (2) low soil temperature, low water temperature, or soil containing hydrogen sulfide and ferrous iron.

Treatment of calcium and phosphorus Metabolism Disorder in Pigs with combination of traditional Chinese and Western Medicine
Calcium and phosphorus metabolic disorders occur in young pigs, resulting in bone dystrophy called rickets. The pathological features were insufficient calcification of osteoblasts and temporary calcification of persistent cartilage hypertrophy and epiphyseal enlargement. The clinical features are digestive disorder, heterophobia, lameness and bone deformation. It is a non-inflammatory disease of bone tissue dysplasia. Vitamin D deficiency also plays an important role in the pathogenesis of rickets. Calcium and phosphorus metabolic disorders occur in adult pigs, resulting in osteodystrophy called osteomalacia, or fibrous osteodystrophy. The pathological feature is the progression of bone

How to prevent and control the shrinkage of rice seedlings due to zinc deficiency
The shrinking seedlings of phosphorus deficiency generally occurred at the tillering stage after slow seedling, such as slow growth, short plant, slender and erect leaf shape, dark green leaf color, neat top of leaf cluster, significant shortening of leaf occipital distance, redness of some tillering leaf tips and even death of old leaves. The reasons are: first, the soil is lack of available phosphorus; second, the soil temperature and water temperature are low, or the soil contains hydrogen sulfide, ferrous and other reducing harmful substances, which reduce the absorptive capacity of roots; third, excessive application of nitrogen fertilizer, the relative balance of effective nutrients is lost. Control measures according to the effective formation of phosphorus measured by the method of soil testing and fertilization

The function of essential nutrient elements in garlic and its corresponding deficiency symptoms
Garlic likes loose soil rich in humus, has strong adaptability to soil acid and alkali, and grows well under slightly alkaline conditions. In different growth stages of garlic, nitrogen requirement was the highest, followed by potassium, calcium, phosphorus and magnesium. For every 1000 kg of fresh garlic, it is necessary to absorb 4.5 kg of nitrogen, 1.3 kg of phosphorus and 4.1 kg of potassium, and the proportion is about 0.25Mel 0.9. The root system of garlic is string fleshy root system, which is mainly distributed in the plough layer of 5-25cm and belongs to shallow root vegetables.

Excessive application of phosphate fertilizer does many harm
1. Due to soil application. There is a close relationship between soil conditions and the efficiency of phosphate fertilizer. In the soil with low content of organic matter and available phosphorus, the application of phosphate fertilizer to most crops can increase the yield. Therefore, phosphate fertilizer should be mainly distributed in the soil with low organic matter content and phosphorus deficiency in order to give full play to the fertilizer effect. Such as red soil dry field, yellow mud field,.
