Where to plant fruit trees should be avoided

First, places with poor lighting, shady slopes, backlit valleys, big trees, and tall buildings, etc., where lighting is not good are not suitable for planting fruit trees. Fruit trees such as peach trees, plum trees, apples, apricot trees and cherries are hi-light plants. If there is not enough sunlight, the branches will die, the flowers become difficult, the fruit setting rate is low, and the fruits taste lighter.

Second, stagnant water in Jishui paddy fields, reservoirs and ponds under the dam, the end of the reservoir, rivers and rivers in the creek, lakes, marshes, inundated with water and other places are not suitable for planting. Most of the roots of fruit trees are afraid of dampness. The more water in the soil will rot the roots, resulting in debilitating trees, poor fruit quality, and low yield.

Third, soil and thin soil layer is too thin, poor soil is not suitable for planting fruit trees. The roots of different fruit trees vary in depth. Except for drought-tolerant dwarf trees, most Qiaohua fruit trees should not be planted in these places. Otherwise, the roots will be stunted, the trees will be weak, the early leaves will fall, and the yield will be low.

Fourth, traffic inconvenient places inconvenient traffic is not suitable for large-scale planting of fruit trees. Because of difficulties in transporting production materials and transportation products, the cost of production is increased and economic efficiency is reduced. To develop an orchard on a large scale in these areas, it is necessary to repair roads and storage facilities in advance.

Vitamin Injection

Vitamin is a kind of trace organic matter that human and animals must obtain from food in order to maintain normal physiological function. It plays an important role in the process of human growth, metabolism and development. Vitamins neither participate in the formation of human cells nor provide energy for the human body.
Vitamins are a class of organic compounds necessary to maintain good health. This kind of substance is neither the raw material of body tissue nor the source of energy in the body, but a kind of regulatory substance, which plays an important role in material metabolism. This kind of substance cannot be synthesized or the synthetic amount is insufficient in the body, so although the demand is small, it must be often supplied by food.
Vitamins are also called vitamins. Generally speaking, they are life sustaining substances. They are a kind of organic substances necessary to maintain human life activities, and they are also important active substances to maintain human health. Vitamin content in the body is small, but indispensable. Although the chemical structures and properties of various vitamins are different, they have the following common points:
â‘  Vitamins exist in food in the form of provitamin;
â‘¡ Vitamin is not a component of body tissues and cells, and it will not produce energy. Its role is mainly to participate in the regulation of body metabolism;
â‘¢ Most vitamins cannot be synthesized by the body or the synthetic amount is insufficient to meet the needs of the body, and must be often obtained from food;
â‘£ The human body's demand for vitamins is very small. The daily demand is often calculated in mg or microgram, but once it is deficient, it will lead to corresponding vitamin deficiency and damage human health.
Different from carbohydrate, fat and protein, vitamins only account for a small proportion in natural food, but they are necessary for the human body. Some vitamins such as B6 and K can be synthesized by bacteria in the intestinal tract of animals, and the synthetic amount can meet the needs of animals. Animal cells can convert tryptophan into niacin (a B vitamin), but the production does not meet the needs; Vitamin C can be synthesized by other animals except primates and guinea pigs. Plants and most microorganisms can synthesize vitamins themselves without having to be supplied in vitro. Many vitamins are components of cofactors or coenzymes.
Vitamins are some small amounts of organic compounds necessary for human and animal nutrition and growth. They play a very important role in the metabolism, growth, development and health of the body. If you lack a certain vitamin for a long time, it will cause physiological dysfunction and some diseases. It is usually obtained from food. At this stage, there are dozens of found, such as vitamin A, vitamin B, vitamin C, etc.
Vitamins are essential organic compounds in human metabolism. The human body is like an extremely complex chemical plant, constantly carrying out various biochemical reactions. The reaction is closely related to the catalysis of enzymes. Coenzyme must be involved in enzyme activity. Many vitamins are known to be coenzymes of enzymes or components of coenzymes. Therefore, vitamins are important substances to maintain and regulate the normal metabolism of the body. It can be considered that the best vitamins exist in human tissues in the form of "bioactive substances".
