In general, the construction of two or more mixed-planted forests can improve the soil conditions and improve the protective effect. However, improper planting of mixed trees not only inhibits growth among tree species, but also causes serious pests and diseases, causing undue losses to production. Here are some combinations that should not be mixed:
1. Commonly used in the buckwheat and mulberry mixed buckwheat trees, there is a toxic substance called alizarin in the body. It has greater antifeeding, sucking, inhibiting development and killing effects on insects, is also toxic to silkworms, and is more toxic to flowers. , If it falls in the mulberry field, poisonous substances can be fumigated and then the acute poisoning can occur when the leaves are fed.
Second, orange trees and mulberries mixed juice sap is a mixture of multiple components, which mainly include aromatic oils, tannins and a variety of organic acids and other substances, the material that can play an allergic reaction to silkworms is mainly aromatic oils. Aromatic oil can cause silkworms to deny food and produce stomach poisoning, which is extremely detrimental to silkworm rearing.
Third, cypress and apple, pear, Begonia mixed cypress and apple, pear, sea bream mixed planting or planting cypress near the orchard, it is prone to Ping rust. Pingya rust mainly damages the leaves, shoots and fruits of apples, pears and sea lice, while cypress is the host of pathogens. After the disease damages apple, pear, and jellyfish, it is transferred to the cypress tree and it is wintering. It damages the twigs of cypress and continues to injure apples, pears and oysters the following year. Therefore, they cannot be mixed together.
Fourth, spruce and Li mixed planted mixed prone to spruce cone rust, susceptible cones early dry, so that seed yield and quality decreased, seriously affecting the spruce natural regeneration and seed collection work.
Five, citrus, grape and eucalyptus mixed banyan tree is a citrus star hornbill, brown celestial cattle like eating trees. If eucalyptus is planted in citrus or vineyards, it will induce a large number of calf to feed and multiply, and it will seriously harm citrus. In addition, it is also easy to reduce the production of grapes.
In addition, Paulownia should not be planted near orchards. Roots of fruit trees often suffer from purple and feathery feathers. The light tree vigor is weak, yellow leaves fall early, heavy leaves dry, and even the whole plant dies. Paulownia is an important host of purple feather disease, thus increasing the incidence of purple feather disease in orchards.
Oyster contains liver glycogen, taurine, a variety of amino acids, vitamins A, B1, B2, D, E, copper, zinc, selenium, manganese, barium, phosphorus, calcium and so on. It is especially rich in selenium and has antioxidant effects . Mushrooms contain crude fiber, semi-rough fiber and lignin that are difficult for the human body to digest.
