According to the age of the tree, different fertilization is adopted. For young fruit trees, due to the less developed root system, in order to avoid the saplings, generally, according to the size of the crown, a circular fertilization method is adopted at the root. For adult fruit trees, an orchard with good lyrics can be applied deep into the hole or applied with acupuncture points, but the large tree is applied 0.8 meters away from the dense roots to induce new roots to extend outward.
Differences in different tree species, growth potential to determine the amount of fertilization in different tree species, growth and soil fertility, the amount of fertilizer required is not the same. The output of fruit trees with a long age and high yield is larger, and the application amount of basal fertilizer is greater. Poor soil and low fertility orchards require large amounts of fertilizer and should be applied in multiple ways. Saplings and fertile orchards should be relatively sparse. However, no matter what kind of fruit trees, basal fertilizer should be dominated by organic fertilizer, such as adult grapes, 2,000 kg of fruit per mu, 4000 kg of fertilizer should be applied to high-quality livestock. Adult pear trees can be used to produce 40-50 kg of ash compost per plant, with 1 kg of phosphate fertilizer, 0.5 kg of potassium fertilizer or 1 kg of compound fertilizer. At the same time, we must also pay attention to the proportion of fertilization, such as peach, each producing 100 kg of fruit should be applied 0.5 kg of nitrogen, phosphorus 0.3 kg, potassium 0.2 kg. In areas where the soil is poor, multi-element complex trace elements must be applied.
Responsive to the disaster, grab the fertilizer for the orchard lack of lyrical, organic active liquid fertilizer can be applied to the trunk of the trunk fertilization, such as available Huimanfeng or Zhuang Fuxing active liquid fertilizer per acre 250 times to water 30 times, at the base of the trunk 50-100 cm brushing, Bark can be quickly penetrated by fruit trees.
Heat meters are one kind of meters measuring the heat
consumption. In order to save the energy and decrease the environment
pollution, the heat meters are more and more popular for the modern buildings.
Heat meters can realize centralized heating supply. Now with the rapid
technology development, the heat meters also experience a fast way of growing
up. Now the government of the world starts to pay much attention to the
building remolding and new buildings heat meter installation. As the new type
of energy calculation, the heat meters have the advantages of higher accuracy,
energy saving and easy installation.
From the functions of the different types of heat meters, there are mechanical
heat meters, digital heat meter,Ultrasonic Heat Meters, M-bus Heat Meters and also wireless heat
meters. Our company, Berggruen Technology Co.,Ltd never stops the steps for
further higher technology research and development. We are devoted to study the
new technology in the world to make better quality heat meters.
