Greenhouse vegetable fertilization precautions

<

1. Rationally apply chemical nitrogen fertilizer and increase phosphorus and potassium fertilizers in an all-round way. Although nitrogen fertilizer is an indispensable fertilizer in greenhouse vegetable production, it cannot be over-used, especially in the mature stage. Phosphorus and potassium, as quality elements, can participate in all biochemical reactions in the vegetable body and activate more than 60 enzymes in the vegetable body so that the stress-resistance performance of the vegetable is significantly enhanced. Therefore, it is necessary to ensure adequate application. In addition, in the production and management of greenhouse vegetables, the number and time of lifting and opening windows should be appropriately increased to increase the light intensity, which will help reduce the content of nitrate and nitrite in vegetables.

2. Chemical nitrogen fertilizers that need to be banned or limited are mainly: (1) It is not suitable to use chlorinated fertilizers. Such as potassium chloride, ammonium chloride and so on. Chloride ion can reduce the starch content in vegetables, make the quality deteriorate, the yield decreases, and the residual in the soil can cause soil decalcification, causing hardening; (2) limited application of magnesium sulfate, ammonium sulfate fertilizers. Because sulfate ions in fertilizers are not easily absorbed by vegetables and stay in the soil, which endangers the growth of vegetables; (3) Limited application of ammonium bicarbonate can easily cause ammonia damage in greenhouses due to volatilization of ammonia gas.

3, the implementation of soil testing formula balanced fertilization, and vigorously promote vegetable-specific compound fertilizer. Specific fertilizers are developed according to the characteristics of fertilizers required by different vegetables and soil supply conditions. The nutrients are more uniform, the nutrition is more scientific, the formula is more reasonable and the pertinence is stronger. After application, the yield of vegetables and the quality of vegetables can be significantly improved.

4, attention, molybdenum, calcium, magnesium and other new fertilizer use. These nutrients can positively improve the quality of vegetables and are also essential for the growth of vegetables.

5. Vigorously promote biological fertilizers. Biofertilizer contains microorganism-activated bacteria. It is a “four-in-one” fertilizer compounded by organic, inorganic fertilizers, fungus fertilizers, and synergists. It realizes the scientific cooperation of various fertilizers and integrates the characteristics of various fertilizers. Complementary advantages are one of the best fertilizer varieties for balanced fertilizer application in greenhouses.

PDT Photodynamical Therapy Anti-aging Muscle Pain Relief Red Light Therapy Belt


850nm and 660nm waves. These have been proven to: stimulate acupuncture points, increase blood circulation and help with antioxidant enzyme release. Phototherapy in this spectrum also promotes muscle relaxation and generally facilitates pain reduction, stimulates fibroblast and collagen production, increases lymphatic drainage, and reduces swelling, inflammation and bruising- bringing relief to athletes, sufferers of arthritis, and those with chronic pain.

The energy can flow through the body and interact with damaged cells in many parts of the body operating more like a vitamin that goes where it needs to go. This wavelength is also best for treating the lymph system and acupuncture points. Whereas studies show near-infrared wavelengths in the 850 nm penetrate deeper through skin and bone for relief of chronic pain.

As with red light therapy, near infrared light therapy does not mask the symptoms of pain, it encourages the healing of the actual cause of the pain. Once absorbed, the light energy kicks off a whole series of metabolic events, stimulating the body`s natural processes on a cellular level. There is an increase in blood flow, allowing the parts of the body to receive the oxygen and nutrients they need in order to function more effectively. Regeneration is stimulated. Inflammation and pain are reduced.

In many cases, after a course of treatment with red infrared light, the pain is gone.
