First, simplify the tree structure, reduce the pruning labor. For example, in the past, the sparse-layered tree structure used by apples in general, the pruning operations are tedious and difficult to grasp by the majority of farmers. However, with the implementation of the dwarf planting orchard, the structure of the slender spine-shaped and improved free-spinning pod-shaped tree is greatly simplified. In pruning, only pruning and branching are used, and there is no need for short cuts. Greatly reduces the amount of trimming operations and is easily mastered by the grower.
Second, improve pest control methods to reduce the number of spraying and dosage. For example, killing insect pests with various kinds of trapping agents can be done by simply hanging a trapping agent tank on the tree and adding a small amount of insecticide; building a good orchard ecology to maintain the dynamic balance of the biological communities in the orchard can control the occurrence of pests and diseases; Measurement of pests and diseases, failure to control the prevention of pesticide spraying; through scientific cultivation measures or resistance to pests and diseases, genetic technology, enhance fruit tree resilience, etc., can reduce or even replace the spray control, save drugs and artificial machinery, etc. cost.
Third, to promote orchard grass, soil no-till. Grass cultivation in orchards is a useful grass species for planting fruit trees in orchards. The developed countries in the world have been popular for more than 50 years, and the penetration rate has reached more than 90%. At present, the dominant grass species is white clover, which can rapidly increase soil organic matter, improve soil and fertility. The annual fixed nitrogen equivalent to 23-30 kg of urea after completion of the planting can satisfy most of the nitrogen fertilizer requirements of most fruit trees, which reduces both the cost of fertilizers and labor costs, and also eliminates the labor-intensive work of soil cultivation. White clover itself is a very good source of honey plants and high-quality feed, can attract a large number of bees to enter the park for fruit tree pollination, promote fruit set, but also to raise livestock and poultry, increase profits; also is an excellent biological measures to improve salt and alkaline soil, while being able to degrade Some harmful substances in the soil in order to avoid damage to fruit trees.
With PSA principles, ETR medical PSA Oxygen Generator can produce 93%±3% purity oxygen gas directly from compressed air. Compared with traditional Bulk liquid oxygen and cylinders oxygen, ETR on-site PSA oxygen generator can reduce cost down to 50 percentages. They can produce oxygen by your will, overcoming the limits of distance, location and transportation.
Compressed air is purified through the air dryer and filters to a certain level for main generator to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The generator produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.
