The strong fruit fat of apples and pears, also called Xia Fei, is applied to the fruit during its rapid expansion. Because at this time the fruit ends the period of seed development and slow growth of the flesh, the pulp cells enter the rapid expansion, and it is the second peak of the root growth and the early stage of differentiation of flower buds. All three need sufficient nutrients to enable fruit development and root system. Good growth and flower bud differentiation. On the contrary, the lack of timely supply of nutrients will aggravate the situation in which the three parties compete for nutrients and are inhibited from each other and cannot proceed smoothly. Therefore, timely application of strong fruit fertilizers to meet the nutrients needed by the three can make the fruit cells grow faster and larger, significantly increase the number of fruit, promote nutrient conversion, strong tree vigor, flower bud differentiation and full. Therefore, this top-dressing is not only a guarantee of high yield and quality in the same year, but also the basis for stable production and high quality the following year, which cannot be ignored. As apple and pear fruits require more potassium in the middle and later stages of growth, phosphorous has less nitrogen, and potassium increases fruit, enhances coloration, improves quality, thickens shoots, grows branches and leaves, grows old, and improves Photosynthetic efficiency, an important element for promoting the synthesis and transportation of carbohydrates. Therefore, the fertilizer is not only nitrogen, phosphorus and potassium, but also in proportion. The ratio of N, P and K is 1.5:3.5:5 for apples and 2:3:5 for pears. Fertilizers are best made from the special fertilizer for apple produced by the fertilizer factory and special fertilizer for pear trees. If no special fertilizer is available, three kinds of quick-acting fertilizers can be used: urea, superphosphate and potassium sulfate, and they are prepared according to the aforementioned proportion and the active ingredients of the fertilizer used. Avoid applying a single fertilizer, especially avoid applying a single chemical nitrogen fertilizer, especially apples, such as applying a single nitrogen fertilizer or applying too much nitrogen fertilizer, it will trigger more and more vigorous autumn shoots, so that the branches and leaves greed for love, poor fruit coloring, reduced sugar , Increased acid content, reduced quality and storage performance, poor flower bud differentiation. The amount of fertilizer applied depends on the size of the tree, the vigor of the tree, soil fat, the number of results and the level of management. The average tree vigor, medium fertility, middle management, and fruit production 60-80 kilograms of fruit trees, each plant applies special fertilizer or self-fertilizer 800-1000 grams, the number of large trees increased in accordance with this amount, Small trees are reduced accordingly. Fertilization method, the smaller tree, along the canopy dripping at 50 cm, open deep and wide each 25-30 cm of the full ring groove or semi-circular groove into; large crown, can dig deep around the crown 25-30 Centimeters and 50-60 cm long fertilization pits are applied with fertilizer, mixed well with soil, and then filled with soil. From the top of the earth, topdressing strong fruit fertilizers, and then spraying with foliar fertilizer, spraying 300-350 times of potassium dihydrogen phosphate or potassium sulfate, or 1,000 times of chelating multi-component fertilizer, amino acid calcium every 7-10 days. Calcium, calcium, Shide, etc., supplemented with potassium, calcium, zinc, boron and other elements, can make the fruit timely and nutrient-rich and full of nutrients, better.
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.
