Garden viticulture techniques - pruning
In recent years, with the reform and opening up and the development of commodity economy in China, garden grapes have developed rapidly and have become an integral part of rural commodity production. They improve people’s lives, increase farmers’ income, beautify the environment, eliminate dust, reduce pollution, and increase lives. Fun is of great significance.
In order to achieve high yield and quality, garden grapes must master key cultivation techniques. Here I introduce the pruning technique.
Grape pruning depends on the peculiarity of pruning. It is the key to success. Therefore, grasping the biological characteristics of various species and correcting pruning correctly are important techniques for the high yield and quality of grapes grown in the yard.
(1) The plasticity of the plastic yard in the courtyard is generally based on multi-master cranial dry type or two long dry types. The disadvantage of the dragon dry type pruning is that the fruiting rate of the mother twigs is low, and the main vines in the lower part of the vine tend to empty eyes. The output is not high. The method to overcome is to strengthen the summer pruning, strictly control the 4-5 branches of the year that are well-kept, and remove all the remaining ones to ensure that their growth and maturation are good.
(b) Pruning
1. Summer pruning: Summer pruning of garden grapes is very important. After the inflorescence appears, regardless of "twins" or "multiple fetuses", only one robust result branch or development branch is left. Weak branches, secretive buds, and dense branches are all removed. In order to increase the fruit setting rate, it is also important to harvest the tips of the branches before and after flowering, and to pick the tips of the flowers. In particular, it is more important for varieties with serious flowering and fruit drop. The picking position can be left at the leaves of 5-6 leaves, and the tip of the pick is removed from the lower third or quarter of the ear. Auxiliary tip processing is to pick up 1-2 secondary shoots at the heart and remove all the rest, and then leave the secondary shoots to leave 2-3 buds topping.
2. Winter pruning: The method of grape pruning in winter should be based on the shaping method. Long dry shaping except extension branches, all use 2-3 bud short tip trim.
a chemical substance derivable from a mold or bacterium that can kill microorganisms and cure bacterial infections.
Antibiotics refer to a class of secondary metabolites produced by microorganisms (including bacteria, fungi, actinomycetes) or higher animals and plants in the process of life, which can interfere with the development of other living cells. Clinical commonly used antibiotics include extracts from microbial culture medium and compounds synthesized or semi synthesized by chemical methods.
The antibacterial or bactericidal effects of antibiotics and other antimicrobial agents are mainly aimed at the mechanism of "bacteria exist but human (or other animals and plants) do not", including four major mechanisms: inhibition of bacterial cell wall synthesis, enhancement of bacterial cell membrane permeability, interference with bacterial protein synthesis and inhibition of bacterial nucleic acid replication and transcription.
Pharmaceutical preparations
After specific API processing - pharmaceutical preparations
The title of API is mainly relative to the preparation.
The raw materials obtained by chemical processing are mainly used to supply the raw materials for the production of finished drugs
For example, cefpirome sulfate for injection is a drug, so cefpirome sulfate is an API
Animal use antibiotic,Veterinary antibiotics,Antibacterials for animals
