Tomatoes in the greenhouse are protected against "flower face"

First, rational fertilization. Flowering faces are prone to occur under conditions of high nitrogen, insufficient phosphorus and potassium, and lack of boron. If the nutrition is excessive, the chlorophyll content increases, and the formation of lycopene is inhibited, and a large number of yellow spots appear on the tomato fruit surface. Such as boron, potassium deficiency, poor nutrition delivery, fruit necrosis brown. If the plant is prematurely decayed, it is easy to cause large macules and green stripe spots due to the formation of lycopene during the process of reddening of immature fruits. It is recommended that the base fertilizer of vegetable growers be dominated by organic fertilizers, and various nutrients should be reasonably matched.

Second, temperature regulation. The tomato fruit surface temperature of more than 32 °C is not conducive to the synthesis of lycopene, the peel will remain green or brown. Below 8°C, the formation of lycopene is disturbed and destroyed, and no longer turns red at the appropriate temperature afterwards. High night temperature and high respiratory intensity are not conducive to the accumulation of nutrients, manifested as poor fruit development. Therefore, pay attention to the appropriate temperature in the development of tomato fruit, to control the temperature of 25 ~ 30 °C, night temperature 13 ~ 17 °C.

Third, light water regulation. When the light is too strong or too weak, it affects the color change. However, when the soil is dry and the evapotranspiration is large, the roots supply nutrients, water, and poor fruit color. Farmers can improve the ventilation and light transmission through pruning. However, at high temperatures, do not let the sun shine directly on the fruit. Take care to keep a leaf above the fruit. Watering to see dry see wet degree, to avoid roots, root damage.

Rheumatoid arthritis (RA) is a chronic, etiology of inflammatory synovitis-based systemic disease. It is characterized by hand, small joints of the joints, symmetry, invasive joint inflammation, often associated with external organ involvement and serum rheumatoid factor positive, can lead to joint deformity and loss of function. According to statistics, the incidence of rheumatoid arthritis in women is 2 to 3 times that of men.It can occur at any age, high incidence of age 40 to 60 years old. People who has rheumatoid arthritis in the late, severe or long-term bedridden patients, due to combined infection, gastrointestinal bleeding, heart, lung or kidney disease can be crisis to life. The main purpose of treatment for Rheumatoid arthritis is to reduce the inflammation of the joints, inhibit the development of lesions and irreversible bone destruction, as far as possible to protect the function of joints and muscles, and ultimately achieve complete disease remission or low disease activity target. Treatment principles include 1. Patient education, 2. General treatment 3. Drug treatment 4. Immune purification 5. Functional exercise 6. Surgical treatment. Anti-Rheumatoid Arthritis drug treatment mainly includes non-steroidal anti-inflammatory drugs, slow-acting anti-rheumatic drugs, immunosuppressive agents, immune and biological agents and botanicals. Over the past decade, the treatment of extra-articular lesions and the emergence of new therapies, so that the efficacy of rheumatoid arthritis has been significantly improved. Most patients with rheumatoid arthritis can get a good control or even complete remission.
