For flower type operation lamp, it has two types of lamp head, one is big one, it has 64 LED bulbs which from Germany osram, another small one, it has 45 LED bulbs, also from Germany. the surgical lamps bulb can last long for 8 hours, that is one of the reasons which our surgical lamp has low maintainance rate. for Double Dome Surgical Lamp, can constituted by one big+one big lamp head, one big+one smal lamp head and one small+ one small lamp head, it can be choosed depends on users' requirment;
the flowet type OT lamp has functions of Bright and Uniform illumination; Outstanding color temperature control performance; Supramaximal effective light field;Electric focusing system;

Avoid doing rootless fertilization at noon. The high temperature at noon makes the liquid fertilizer not only evaporate quickly after being sprayed, but also cannot be well preserved in the body surface of the crop, and it is difficult to be absorbed by the pores and lenticels soon.
Avoid nitrogen fertilizer on topsoil. Apply nitrogenous fertilizer to the shallow layer of the topsoil, and nitrogen is easily decomposed and evaporate when exposed to sunlight.
Avoid excessive application of high concentrations of fertilizer. Regardless of the type of fertilizer, if the amount is too large, the root system of the crop will “suck down†and cause damage to the roots.
Avoid spreading with water. Phosphate fertilizer and potash fertilizer are easily fixed, and nitrogen fertilizer is easy to evaporate and lose. Fertilizers applied with water basically stay in the topsoil, and the fertilizer utilization rate is very low.
Avoid ammonia and ammonium bicarbonate in greenhouses or greenhouses. Because the ecological environment in the greenhouse is closed at high temperature, the two fertilizers are easily volatilized under high temperature and confined conditions, causing the plants to be smoked and affecting normal growth.
Avoid "Lalang match." Irrespective of the nature of the fertilizer, it is unscientific to mix and apply it arbitrarily. If ammonium fertilizer is applied in combination with alkaline fertilizers such as grass ash, lime, and phosphate fertilizers, it will inevitably accelerate the volatilization of nitrogen, cause waste of fertilizer, and also cause damage to crops.
Avoid application of phosphorus fertilizers. Phosphorus is very mobile in soil, and it is particularly easy to apply it to the surface of the soil for adsorption and fixation, which greatly reduces the fertilizer efficiency of phosphorus.
Avoid applying excessive nitrogen fertilizer to legume crops. The roots of leguminous crops are affiliated with Rhizobium. If nitrogen is used excessively, it will directly affect the ability of Rhizobium to fix nitrogen.
Avoid excessive application of chlorinated fertilizer to sensitive crops. Tobacco, citrus, potato, and grapes are sensitive to fertilizers. Do not apply too much chlorine at a time, otherwise it will affect normal plant growth.
Avoid applying fertilizer before heavy rain. Because in the event of heavy rain or showers after fertilization, the fertilizer is easily washed away by the rain, causing loss of nutrients.
Avoid boiled fertilizers. The application of zinc fertilizer, molybdenum, boron and other fertilizers can solve the problem of crop nutrient deficiency, but if single application of micronutrient fertilizer will cause crop malnutrition, growth and development are hindered.
Avoid applying a single fertilizer. The ideal fertilization method is to apply organic fertilizer first, then apply nitrogen, phosphorus, and potassium fertilizers in a reasonable way and apply them scientifically.
