The main purpose of rapid tree-forming is to create conditions for entering the high yield period. The management of saplings is dominated by long trees and shaping, and management must be focused on these two purposes.
1. Autumn basal fertilization: In the fall of fruit trees, rooting and nutrient reserve are the main factors. At this time, fertilization and fruit trees take a long time to absorb. Most of the nutrients absorbed are stored in branches and roots and used as leaves for the next year. The top dressing is mainly organic fertilizer, plus appropriate amount of compound fertilizer. According to the size of the tree, generally, each tree chases the cooked organic fertilizer 3-5? + compound fertilizer 0.2-0.3? or so, when the chase is applied, the groove is used to dig the ditch around the circumference of the canopy, and the depth of the ditch is about 30? Mix well with the soil, backfill, and water immediately. This fertilizer is very critical in the growth of fruit trees and must be applied early.
2. Seal winter water: Before the winter, pour large water once. After pouring, the base of the tree will be piled up and piled up so that all the intermediate anvil parts will be buried in the soil to avoid freezing. In the spring of the second year, the cover soil should be opened in time to avoid rooting and losing the dwarfing effect.
3, winter shear: The key to dwarfing and dense planting is to cultivate the worm-shaped tree shape. The key to spinning worm-shaped culturing is the management of the first two years after planting. In the first year, the winter stalks will dry all the twigs that are planted. Short cuts, forced recurrences, making the age of branches of the main branch lower than those of the middle stem, thus ensuring the leading role of the central leadership.
4, budding fertilizer: After the winter cut, timely fertilizer, carved out of the lack of branches, which will help shoot branches, and the new branches issued almost the same size, easy to control the tree.

With the development of large-scale and intensive aquaculture, the scale of aquaculture is amazing, and the economic benefits in the absence of infectious diseases have indeed brought considerable economic benefits to the aquaculture industry. At the same time, it has made a significant contribution to promoting economic construction and improving human living standards. However, with the development of aquaculture today, there are many problems that have plagued the aquaculture industry, That is, livestock and livestock have been the timing of the outbreak of infectious diseases, which has brought huge economic losses to the entire breeding industry, so we have to rely on a large number of animal drugs, a large number of antibiotic drugs to fight against the outbreak, resulting in serious food pollution, such as: the residues of drugs and antibiotics in meat and eggs seriously exceed the standard, Excessive residues of a large number of drugs after use will directly threaten human health. However, this will bring disastrous consequences to the entire breeding industry, that is, human beings are more and more afraid to eat meat and eggs. If we continue not to start from the source of breeding pollution, then the consequences will be unimaginable.
Because the breeding environment can not be fundamentally improved from the source, the use of a large number of drugs and antibiotics can not be avoided. In fact, it is completely possible to realize ecological breeding and green breeding from the perspective of environmental cleaning and daily disinfection, and farmers can also save a large amount of drug costs.
