Most fruit trees enter dormancy during the winter. At this time, the deciduous fruit trees are basically defoliated and shoots stop growing. However, a series of activities such as respiration, transpiration, differentiation and development of roots, and root absorption are still performed inside the tree body. Evergreen fruit trees slow down as the temperature decreases. According to the growth characteristics of the fruit trees, the orchards should be managed in the winter—pruning. Reasonable winter pruning of deciduous fruit trees can enable fruit trees individuals to make full use of space, improve light energy utilization, improve ventilation and light transmission conditions, reduce pests and diseases, improve fruit quality, and can reasonably distribute nutrients to maintain the coordination of growth and results. The role of balancing and extending economic life is one of the important measures in the production of fruit trees. Therefore, peaches, pears, grapes and other deciduous fruit trees should be trimmed in time, generally before the Spring Festival. The pruning method should be treated separately according to the growth characteristics of different tree species, and measures such as short cutting, thinning, and sparsing are mainly adopted. Young trees should also be used for branching operations. In short, they should be cultivated in the winter to produce trees with reasonable yields. Park. Reasonable garden closure can effectively reduce the orchard's overwintering base in the orchard. Deciduous fruit trees can be removed after pruning in winter orchard with dead branches, diseased leaves, stamens, leaves, etc.; scrape off branches and spots, protect wounds with 402 antibacterial agent 50 times; crown spray 95% oil emulsion 50 times or 45% crystal lime sulfur 30-50 times liquid closure garden. Evergreen fruit trees (citrus, etc.) can be sprayed with 95% oil emulsion 100-150 times liquid or 45% crystal lime sulfur 200-300 times. However, it should be noted that lime sulfur and oil emulsion cannot be applied at the same time, and the two should be separated by 20 days, otherwise it is easy to produce phytotoxicity. Reasonable filling. An orchard that lacks plants should make up for shortages in time. The deciduous fruit trees should be replanted before the Spring Festival and the evergreen trees should be replanted in the middle of February and the middle of February.
Nutriceutical Ingredients
These ingredients mainly include the following categories
Nutriceutical Ingredients refers to the various chemicals contained in food that are necessary for maintaining human growth, development, metabolism and health.
1. Macronutrients
Carbohydrates: The body's main source of energy, including sugar, starch and fiber.
Protein: The building blocks of body tissues such as muscle, skin, enzymes and hormones, but also provides energy.
Fats (lipids) : are another important source of energy, involved in cell building and hormone production, including saturated, unsaturated and essential fatty acids.
2. Micro-nutrients
Vitamin: is a group of organic compounds, the human body needs a small amount, but essential to normal physiological function, can not be synthesized by the body itself or the amount of synthesis is insufficient, must be taken through food. For example, vitamin A, vitamin C, vitamin D, etc.
Minerals: including macroelements (such as calcium, phosphorus, potassium, sodium, magnesium) and trace elements (such as iron, zinc, selenium, iodine), essential for the maintenance of homeostasis, bone structure, nerve conduction and other functions.
3. Water
Although not a "nutrient component" in the usual sense, water is indispensable in the activities of life, participating in all biochemical reactions, maintaining body temperature and fluid balance in the body.
4. Dietary fiber
Although it cannot be digested and absorbed by the human body, it plays an important role in promoting intestinal health, controlling blood sugar and lipid levels.
A balanced intake of these nutrients is essential to maintaining good health. People of different ages, genders, physical conditions and activity levels also have different requirements for various nutrients.
