Why navel oranges need to "sweep spring shoots and summer shoots"

For the navel orange trees one year before or after they are put into production, “smooth spring shoots and summer shoots” is an important measure to increase fruit production. However, because many farmers will not use or implement improper methods, they will not only fail to achieve the expected goal of high yield, but will result in the consequences that the navel orange has a small crown, less foliage, and lower yield. The scientific operation method of “discharging spring shoots and summer shoots” is described below as reference for fruit farmers. 1, sparse spring shoots. The result is that the navel orange tree is appropriately removed from the spring shoots, so that it can play a role in promoting fruit production and protecting fruits. Adult results Navel orange trees, less spring shoots and important results in the second year of the mother branch and the base of the autumn shoots, the amount of thinning spring shoots should be light, generally eradicating late shoots; early results of young navel orange trees , is in the vegetative growth to reproductive growth transformation stage, should be sparse spring shoots, in order to promote adequate autumn shoots, as the result of the next year the mother. Specific elimination methods: First, the amount of sparse should be due to trees and appropriate, generally remove 40-60% of the spring shoots; second, the branches of the flower buds on the branches of spring shoots should be sparse, can be sparse 1 /3-1/5, and to eliminate some of the poor quality and redundant flowering branches, in order to stabilize the flower steady fruit; the spring branch of the spring shoots on the branches less fruiting branches should be light or sparse, can be 2-3 When picking leaves topping, in order to reduce nutritional contention and promote fruit development; Third, the spring shoots without flowers and fruitless branches, generally not sparse or less sparse, to ensure that there are enough branches as the result of the next year the mother of the branch or the autumn shoots of the base , conducive to the next year's flowering results; the fourth is to Wangshu spring shoots should be more sparse, sparse branches; the weak tree spring shoots should be sparse or not sparse, weak branches; on the spring tree shoots of the golden mean mainly weed out weak branches, keep Tree vegetative growth and reproductive growth balance. 2, wipe summer shoots. In the young and mature trees that are put into production, too much hair extract in summer shoots will cause competition conflicts between shoots and fruit, causing severe secondary physiological fruiting and greatly affecting the yield increase. The summer shoots must be wiped out in time. The method is: the empty parts of the canopy or the summer tips that need to expand the crown can be preserved. Only 6-8 leaves are needed to pick up the heart to promote branching and replenish the canopy; the rest of the summer shoots grow to 2- All 3 cm long erased, wiped every 5-7 days, until the release of autumn shoots 3, grasping matching. Navel orange shoots summer shoots must also grasp two complementary measures: First, to strengthen the roots outside the fertilization, spring shoots, flowering period, spraying "0.2% boric acid or borax +0.3% potassium dihydrogen phosphate +0 .3% urea "mixed fertilizer solution, spraying once every 7-10 days, even spraying 2-3 times to promote the growth of spring shoots and preserved fruit; second is the emphasis on summer pruning, the results of the tree sparse most of the spring After shoots and summer shoots have been reduced, the number of branches and leaves and the year-old branch of autumnal shoots or autumn shoots are reduced. A summer cut should be carried out in time to promote the development of a large number of autumn shoots as a result of the mother shoots and guarantee high yields in the coming year. The pruning period is generally in mid-late July. The amount of pruning is appropriate to tree vigor. Before 3-5 days of pruning, the nitrogen, phosphorus and potassium compound fertilizer is reapplied, which promotes neat and vigorous autumn shoots. At the same time, it is necessary to control the leaf miners and Locust damage.

Plant Extract

Plant extracts refer to a class of substances derived from plants that have one or more biological functions. Can be separated by physical and chemical extraction of one or more effective components formed by natural products.
There are many kinds of plant extracts. At present, natural plant extracts mainly include essential oils, saponins, alkaloids, polysaccharides, polyphenols, flavonoids and so on. According to the biological activity, it can be divided into antioxidants: grape seed extract, green tea extract, pine bark extract, etc. Immune modulators: ginseng extract, gynostemma pentaphyllum extract, Ganoderma lucidum extract, etc. Improve cardiovascular function: ginkgo biloba extract, lotus seed heart extract, rhodiola extract, etc. Sedative: valerian extract, hop extract and so on.
According to their own characteristics in the market application of plant extracts can be roughly divided into six categories: coloring, seasoning, medicinal, health, dietary supplements and feed additives. Natural plant pigments refer to pigment components in roots, stems, leaves, flowers, fruits and bark of plants, such as turmeric, sappanwood, indigo, safflower, black bean and green walnut peel. Natural plant pigments are widely used in food, textiles, cosmetics, medicine, leather industry, printing and dyeing and other industries.
Plant extracts are rich in ingredients that can effectively stimulate the senses, such as sweeteners and volatile substances. Natural sweeteners, such as stevia glycoside and grosvenin, are popular new sweeteners. They are not only sweet, but also ideal substitutes for sucrose. Essential oils are concentrated volatile substances that are commonly used in the preparation of fragrances and are widely recognized in plant extracts.
Contained in the plant extracts of saponins, alkaloids, polyphenols, flavonoids and other ingredients are widely study has many biological activities, such as antioxidant, antibacterial, anti-inflammatory, improve animal production performance, antivirus, enhance immunity, etc., for human and animal health has the effect of nots allow to ignore, and the development of its pharmacology and health care function has become the main trend of plant extracts.In addition, as a dietary supplement, it is one of the main applications of various plant extracts. Such as oligosaccharides (oligosaccharides, oligosaccharides, oligosaccharides, galactose, etc.) dietary fiber, soybean protein, dietary fiber, wheat albumin, L-arabinose, sugar alcohol (xylitol, malt heavy sugar alcohol, sorbitol, etc.) and other natural plant food additives have been widely used in the food health care market. Many plant functional ingredients with anti-inflammatory, antioxidant and bacteriostatic properties are also commonly used as substitute anti-bacterial products. The application of green feed additives in livestock and poultry production has been vigorously developed, such as green tea polyphenols extract, pine bark procyanidins extract and polyanthocyanidins extract.
Due to the changes in lifestyle, working mode and consumption mode, more consumers are pursuing the life concept of "big health". The so-called "big health" refers to a concept of whole-process, comprehensive and total factor care for people's life around the basic necessities of life, life, old age, illness and death. It not only pursues individual physical and physical health, but also pursues mental, spiritual, social, environmental and family health. In the era of "great health", natural plant-based health products are the core and the key material basis.
With increasing attention to the food and drug safety, from natural plant in the development and utilization of the active ingredient is becoming more and more attention, a large number of food safety, have certain curative effect function of plant extracts have been used as raw materials in a variety of ways into functional food nutrition and health food has entered people's lives, and will play a more and more important role.
And more and more new research new discovery, predicts that the plant extract industry chain will have more members to join, there will be more business opportunities. The future domestic plant extract market will stride forward gradually to mature period!
