Fertilization time is the key period of flower bud differentiation of kiwifruit. According to the maturity of each variety, the fertilization time should be controlled after fruit picking and before defoliation. After fruit picking, because the leaves lose the role of regulating water, temporary functional decline often occurs, so the base fertilizer should be applied early. Before the application of fertilization, the 0.5% urea solution was sprayed once on the leaves, which could increase the photosynthesis of the leaves, promote the return of nutrients to the roots and stems, and increase the nutrient reserve. At this stage, kiwifruit tree fertilization should be applied with NPK fertilizer, mineral fertilizer and organic fertilizer. In the fruit-fruit kiwifruit tree, the total fertilization amount of NPK is 0.5 kg, and it is applied at a ratio of 1:1:1; the mineral fertilizer is applied to each tree 0.25 kg; the total fertilization amount of each tree of bio-organic fertilizer It should be kept at 1.5~2.5 kg. Fertilization method Root fertilization can be carried out in three ways: whole garden application, hole application and ditch application. After fertilization, it should be irrigated once in a timely manner; foliar spray method is simple and easy to use, with small fertilizer amount and quick effect, but need to pay attention to Yes, it is best to do it on a cloudy, sunny morning or in the evening without wind.

Polysaccharides composed of the same monosaccharides known as homopolysaccharides, such as starch, cellulose and glycogen; polysaccharides composed of different monosaccharides known as heteropolysaccharides, such as gum arabic is composed of pentose and galactose. Polysaccharide is not a pure chemical substance, but a mixture of substances with different degrees of polymerization. Polysaccharides are generally insoluble in water, have no sweet taste, cannot form crystals, and have no reducibility or change of spin. Polysaccharides are also glycosides, so they can be hydrolyzed, and in the process of hydrolysis, they tend to produce a series of intermediate products, and eventually completely hydrolyzed to obtain monosaccharides.
