Jujube soil fertilizer and water management
Soil and fertilizer water management is the basis for ensuring the growth and development of jujube trees and early fruit production. Only scientific soil and water management can promote the growth of root systems, increase the ability of roots to absorb, synthesize and operate water and nutrients, and improve and enhance tree nutrition. The status promotes the growth of the tree's above ground and achieves the goal of high yield and quality. Jujube soil fertilizer management can be summarized as "three fat three water three loose soil."
"Three fertilizers" are basal fertilizers. Generally, it is advisable to use medium-maturing varieties such as Jinsixiaozao in late September for harvesting or to pick up late-maturing varieties such as winter jujube. The temperature difference between day and night is large, and the leaves still have high photosynthetic rate. The efficiency is beneficial to the accumulation of organic nutrients; the base fertilizer is mainly organic fertilizers such as decomposing circle fertilizers and manure fertilizers, and can be mixed with appropriate amounts of nitrogen and phosphorus quick-acting fertilizers. Phosphate fertilizers should be mixed with organic fertilizers first to improve fertilizer efficiency. The second is topdressing, which can be applied in the pre-emergence, flowering, and young-fruit topdressing at the end of May and the middle of July. The pre-emergence topdressing is mainly available nitrogen fertilizer; the topdressing fertilizer at the flowering stage is mainly available nitrogen fertilizer and is supplemented with appropriate amount of phosphate fertilizer; young fruit During the period of fertilization, compound fertilizers containing nitrogen, phosphorus, and potassium are the main components, and nitrogen fertilizers must not be applied. The third is foliar spray fertilizer, combined with spraying fertilizer to spray leaf fertilizer in the growing season. It is simple and easy to use, saves labor, uses less fertilizer, and has quick effect. The type and concentration of foliar spray fertilizer are: 0.3% to 0.5% of urea and 0.2% ammonium sulfate. % to 0.3%, ammonium phosphate 0.5% to 1.0%, zinc sulfate 0.3%, ferrous sulfate 0.3%, borax 0.5% to 0.7%, calcium superphosphate leachate 2.0%, potassium dihydrogen phosphate 0.3%.
"Sanshui" is a prime water, jujube tree watering before germination, can promote root growth and its absorption and operation of nutrients, jujube tree can germinate early 5 to 7 days, is conducive to the growth of jujube and jujube hanging and flower bud differentiation , Make flower development robust, improve flower quality, promote fruit set and young fruit development. The second is to help flower water, jujube flower is very sensitive to water, flowering in the event of drought, often lead to a large number of jujube tree flowers off, affect fruit set, in the early flowering stage to take soil watering or flowering canopy crown water, can increase soil and air Humidity is conducive to pollen germination and fertilization, increase fruit set rate and promote fruit development. The third is to promote fruit water. In early July, the jujube tree is growing rapidly. Combining top dressing with irrigation can promote cell division and growth and promote fruit enlargement.
"Three loose soils" are first to plow the soil. Plowing the soil in the late autumn or early spring can increase the soil permeability, increase the temperature of the soil, facilitate the development of the root system, and increase the ability of the roots to absorb water and fertilizer. In the early winter, plowing can also prevent precipitation. Helps eliminate overwintering pests; tilling depth 15 to 30 centimeters, near the trees should be shallow, so as not to hurt big roots. The second is cultivating the weeds and cultivating the soil. After the growing season, especially after the rainfall and watering, timely dip the soil of the jujube orchards to a depth of 6 to 10 cm and remove the weeds, which can reduce the competition for weeds on the water and nutrients and make the soil Loosening, reducing evaporation, promoting soil microbial activity, increasing soil fertility. Third, the intercropping of green manures covers the green crops. Intercropping green manure can make economic use of the land, save manpower for weeding, and provide organic fertilizers with rapid fertilizer effect. The roots of green manure remain in the soil to improve the soil; and green manure can cover the ground and play a role. Wind, sand and soil, and the role of soil and water, suitable for the intercropping of jujube garden green beans are beans, wolfberry fruit, Sesbania, grass hibiscus and alfalfa and so on.
For the treatment :
[Of all the diseases of the nervous system, the most common difficulty that people have is pain, and much of that is nerve-related," according to Dr. Shai Gozani, founder and CEO of NeuroMetrix, a medical device company. [There are 100 million people who live with chronic pain."
According to the Mayo Clinic, patients with nerve disorders experience functional difficulties, which result in conditions such as:
Epilepsy, in which abnormal electrical discharges from brain cells cause seizures
Parkinson's disease, which is a progressive nerve disease that affects movement
Multiple sclerosis (MS), in which the protective lining of the nerves is attacked by the body`s immune system
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a motor neuron disease which weakens the muscles and progressively hampers physical function
Huntington's disease, which is an inherited condition that cause the nerve cells in the brain to degenerate
Alzheimer's disease, which covers a wide range of disorders that impacts mental functions, particularly memory.
Mayo Clinic also noted that the nervous system can also be affected by vascular disorders such as:
Stroke, which occurs when there is bleeding on the brain or the blow flow to the brain is obstructed;
Transient ischemic attack (TIA), which are mini-type strokes that last a shorter period of time but mimic stroke symptoms; and
Subarachnoid hemorrhage, which is specifically bleeding in the space between your brain and the surrounding membrane that can be the result of a trauma or rupturing of a weak blood vessel;
Infections such as meningitis, encephalitis, polio, and epidural abscess can also affect the nervous system, the NIH noted.
Treatments vary from anti inflammatory medications and pain medications such as opiates , to implanted nerve stimulators and wearable devices, Gozani said. [Many people also turn to herbal and holistic methods to reduce pain, such as acupuncture."
