The high yield of pepper is inseparable from fertilization, but in actual production, many vegetable farmers lack rational knowledge, and they rely on perceptual experience to arrange production, which is easy to reduce production. Cao Zhengping, a technician of Yangling Modern Agriculture Precision Poverty Alleviation Demonstration Park, specializes in the majority of vegetable farmers, and do not fall into these misunderstandings.
Misunderstanding, the more the pepper is fertilized, the higher the yield, the more the real fertilizer is, the more likely it is to cause the damage.
The total salt content of the soil required for the normal growth of pepper is 2000-3000 mg/kg. If the root system exceeds 6,500 mg/kg, the reverse osmosis will appear and the length will be poor, and the yield will naturally decrease. The temperature in the greenhouse is high, the humidity is high, the decomposition of organic fertilizer is fast, the amount of nitrogen volatilization is large, and the excessive application of fertilizer is easy to cause fertilizer damage.
In general, the average utilization rate of nutrients in various crops is 30%-40% for potassium, 40%-50% for nitrogen, and 10%-20% for phosphorus. According to the characteristics of the fertilizer required by the pepper and the specific fertilizer supply conditions in the shed, scientific and rational selection of high-quality fertilizer, only balanced, comprehensive fertilization, can achieve high quality and high yield of pepper. Within a certain range of fertility, as the amount of fertilizer applied increases, the yield increases.
Misunderstanding, one seedling, more yield, high truth, close planting, low yield
Many vegetable farmers want to stay a few more when they stay in the seedlings, planting some of them, and think that the seedlings are more productive. According to the measurement, 4 peppers per square meter are planted, the plant is 50% nutrient-consuming photosynthetic product, and the fruit can be 50%; if 8 plants per square meter, the vegetative consumption of photosynthetic products is 70%-80%, the product It can only account for 20% to 30%, but dense planting has a low yield.
Misunderstanding, the temperature is high, the temperature is too fast, the temperature is too high, and the production of pepper plants is unbalanced.
Many vegetable farmers believe that the greenhouse is built to keep warm, and the high temperature pepper grows fast. In fact, capsicum has an upper limit on temperature: generally 25 to 32 °C. If the temperature is too high to inhibit the young fruit, fruit breaks will occur. At the same time, the temperature is too high, the respiration is large, the body is running disorderly, the plant body is long, the plant vine and reproductive growth are not balanced, but the yield will decrease.
Misunderstanding, a plant grows well, and the truth of the plant will increase the nutrient accumulation of the product and affect the yield.
Most people think that the plant is a good crop. In fact, the water leaves are too shallow, the nutrient incomplete yield is low, and the excessive growth of nutrients will inevitably affect reproductive growth, but the yield is low. In addition, excessive plant growth will inevitably affect the nutritional accumulation of products, photosynthetic products consume large, and yield is also poor.
Misunderstanding, a dozen drugs, less disease, less truth, fight drugs, will affect the disease resistance of pepper
Many vegetable farmers in the middle and late stages of pepper growth, taking a drug every 2 to 3 days, think that the drug has spread so hard and spread so fast, not to fight hard, it will ruin. In fact, during this period, diligent drugs also interfered with the normal operation of synthetic carbohydrates in crops, and were not conducive to the production of antibiotics in plants, but the disease resistance decreased.

In order to provide sufficient height difference between the patient's arm and the infusion solution during gravity infusions, the infusion bottles are typically hung on a Infusion stand. We offer you a wide assortment of mobile infusion stands with various specifications on which multiple infusion bottles can be simultaneously hung and which are quite flexible, thanks to the smooth-rolling castors. Of course, we also supply Drip stand without castors, but the height could be adjust.
Except Infusion stand, if you looked for Patient Stainless steel waiting chair or Transfusion chair, you will find it in out category of Hospital Furniture. Or you can contact our services through message, telephone, online request or live chat.
