Two adjustments to control the preservation of fruit and nutrition

At present, it is the critical period for jujube tree to keep flowers and preserve fruits. If improper management, such as fertilizer, water, and trace element supplementation are not timely, it will often result in falling flowers and falling fruit.

The "two adjustments and one control" technology has succeeded in jujube blossoming and fruit preservation, but there are still people who do not know that "two adjustments and one control" are a concept. "Two adjustments", first, underground conditioning - rational fertilization, jujube organic fertilizer and phosphorus and potassium fertilizers mainly; second conditioning on the tree - the tree reaches the ventilation of the tree to supplement the trace elements and nutrient solution. "One control" is to regulate tree vigor with lover-admission fruit tree regulators. In the treatment of "two adjustments and one control," if you only pay attention to conditioning and chemical control in the trees and neglect the underground conditioning, you may have the following problem: What medicine do you use for me? Well, it is definitely a problem with your medicine. In fact, the fundamental reason is that there is no organic fertilizer applied in the fall, there is no top dressing in the growing season, and the nutrition in the ground cannot keep up. The supplement of the leaves alone is not enough.

Jujube trees require a lot of nutrition during the flowering and fruiting period. If the nutrition cannot catch up and can't be accumulated, the flowers and fruits are in a state of starvation, which will result in falling flowers and fruit. For example, a jujube farmer in Evergreen Village, Yongji City, only pays attention to the nourishing and chemical control in the trees, but neglects the underground conditioning - rational fertilization. I asked: "Isn't the fertilization last fall? After the flowering and fruiting period, I didn't catch any fertilizer?" He replied: "No." It turned out that the most critical underground conditioning in the "two tone and one control" technique was ignored by him. The tree caused malnutrition, falling flowers and falling fruit. The juvenile farmer did not realize this, but he believed that it was caused by improper use of certain pesticides during the flowering period. In their villages, most fruit growers manage jujube trees according to the same plan, but other people's dates are good. In addition, a juvenile farmer told me that he also used the same pesticide this year. This year's jujube sits particularly well, among which 100 jujube trees have not yet been girdled. He said that although there is no jujube girdling jujube tree sits jujube than the jujube dates jujube tree sitting slightly less, but if nutrition can not catch up, girdling production is much less than the date without jujube peeling. The jujube tree of the first jujube farmer was not girdled, but because of lack of nutrition, the nutrition accumulation was not good, resulting in a large number of falling flowers and falling fruit. The jujube wanted to give up management. I suggest he can't give up! Because there are still some flowers and fruit in the trees, if we strengthen management, we must quickly apply topdressing in the underground, apply half a bag of grain shellfish per half a half-bags of potash per acre, or apply a bag of hops per acre, which should be able to Minimize losses.

In short, "two adjustments and one control" is a comprehensive technology. It is not a matter of taking medicine several times to solve the problem. This point has been exemplified by countless successful things.

Hyaluronic Acid Eye Drops Sodium Hyaluronate (HA), Pure Hyaluronic Acid could be used in eye surgery, such as Hyaluronic Acid Eye Drops, corneal transplantation, cataract surgery, glaucoma surgery, and surgery to repair retinal detachment.

Eye Drop Grade Hyaluronic Acid Powder is an important component of intercellular substance, eye vitreous body, joint fluid and other connective tissue. It acts the important physiologic roles in holding body's moisture, maintaining extracellular space, adjusting osmotic pressure, lubricating and promoting cells to repair in the body. Sodium Hyaluronate can be used as viscoelastic agent inintraocular lens implantation operation, as the filler in the osteoarthritis and rheumatoid arthritis and otherjoint surgery, as a medium widely used in eye drops, it also can be used to prevent postoperative adhesion and facilitate the wound heal. The compounds formed by the reaction of Sodium Hyaluronate with other drugs play a drug release effect role, thus achieve the purpose of drug targeted and time controlled release.

With the development of medical technology, Sodium Hyaluronate has been more and more widely used in medical applications. In 1976, Sodium Hyaluronate was first commercialized and used as ophthalmic viscoelastic agents, which is a significant progress in the ophthalmic industry. In 1987, Sodium Hyaluronate for intra-articular injection came in to the market. In 1990s, the large-scale production of Sodium Hyaluronate by fermentation made the cost lower, thus products containing Sodium Hyaluronate such as eye-drops, dermal fillers and other Sodium Hyaluronate preparations started to be used extensively.
