Red Fuji is not red

Red Fuji apples are light red or not colored, and there are many reasons. The first is related to the variety. The poor coloring of fruits is determined by the biological characteristics of the varieties themselves, and has nothing to do with environmental conditions. The second is related to the timing of harvesting. Red Fuji apple is a late-maturing variety, and it is generally better to harvest and color it in late October. However, some areas harvested in late September. Even colored varieties are harvested too early and their coloring is not good. The third is improper use of fertilizer. Scientific fertilization is an important factor in the production of fruit trees. Nitrogen, phosphorus and potassium fertilizers are used in proportion. Otherwise, with nitrogen fertilizer alone, coloring is poor. Fourth, improper pruning, excessive growth of tree vigor, many leaves and shading, light energy utilization is low, the fruit is shading, poor coloring, and even the backlight surface is not colored The fifth is the fall drought, soil moisture, low air humidity, day and night The small temperature difference is also an important factor causing the poor coloring of Red Fuji.

To solve the problem of poor coloring of Red Fuji apples, we must combine the above factors and join the seat. If it is a species problem, it can be replaced by a higher one and marry a good variety; if it is harvested too early, the harvest can be delayed until it is well colored and then harvested; if the fertilization is unreasonable, nitrogen, phosphorus, and potassium are proportionate. With the application; if it is prune unreasonable, in the fruit dormancy period, growth period can be pruned, adjust the lighting condition of fruit trees, is conducive to photosynthesis, vegetative growth and reproductive growth reasonable. If it is autumn drought, timely watering, increase soil moisture, to meet the needs of fruit tree growth, development, and can adjust the humidity of the air; day and night temperature difference can delay the harvest time, when the temperature difference between day and night, Red Fuji fruit coloring fast And then harvest.

Goji Polysaccharides is a rare plant polysaccharides containing protein, which have side chains of polysaccharide composed by six carbon sugars (rhamnose, arabinose, xylose, mannose, galactose, glucose) and main chains of protein composed by 18 kinds of amino acids. The glycoproteins with biological activity is a high-strength immune enhancer.

Wolfberry products with stable quality are all natural, safe, sanitary and fast absorption.Lycium barbarum polysaccharide extraction and purification is divided into two steps. First, the extraction of Chinese wolfberry crude polysaccharides, the second is purified Lycium barbarum polysaccharide. Crude polysaccharides extraction process is as follows: Weigh dried crushed medlar, petroleum ether: acetone (1: 1) reflux degreasing, the solvent was filtered off, the residue was air-dried 80% ethanol off monosaccharide and oligosaccharides. 
The polysaccharide is extracted by water after dissolving the residues such as oligosaccharides in water at 90-100 DEG C, the extract is concentrated under reduced pressure, the polysaccharides are precipitated by ethanol, the precipitates are washed with anhydrous ethanol and acetone, and the lycium polysaccharides are dried under vacuum. The crude polysaccharide is purified by passing the Lycium barbarum polysaccharide through a column of DEAE cellulose with different concentrations of NaCl as an eluent, concentrating the eluates with different salt concentrations respectively under reduced pressure, desalting them by dialysis, and then lyophilizing them differently Grape Lycium glycoprotein.

 

Modern medical research suggests that wolfberry polysaccharides can improve human immunity and have functions as anti-cancer, cancer treatment, hematopoiesis, liver protection and hypotensive, free radicals removal , anti-fatigue, anti-radiation, and cell activity improvement; Goji polysaccharides can control cells division& differentiation, and regulate cell growth & aging, which is widely used in the pharmaceutical, health food and other fields.
