In the autumn and winter, the management of the orchard has reached a critical period, and the management of the peach orchard has also entered an important stage during this period. Xu Ying, a researcher at the Shandong Institute of Fruit Research, reminded fruit farmers that they should pay attention to the management of peach trees after picking fruits to ensure that the peach orchard can survive the winter safely. Reasonable fertilization The types of fertilization are mainly high-quality organic fertilizers mixed with appropriate amounts of nitrogen, phosphorus, and potassium compound fertilizers and micro-fertilizers. In addition, extra-root topdressing can be used to supplement nutrition, and a certain amount of micro-fertilizer can be applied according to the nutritional status of the tree. Peach trees have a higher fruit setting rate and higher requirements for soil nutrients. Adequate base fertilizer is the basis for a strong, high-yield, and stable peach tree. Cultivation pruning peach orchards with heavy soil or weeds should pay attention to the drainage system before the rainy season, lower the groundwater level, remove weeds, and try to avoid stagnant water. The cross branches, overlapping branches, diseased and insect branches, and weak branches in the canopy are thinned out. Use the method of short-cutting the shoots, and select the new shoots close to the backbone branches for heavy-cutting, so that new fruiting shoots will be produced. The pests and diseases of fruit trees are hidden in the leaves, dead branches and soil in different forms in winter. When the garden is cleared, the dead branches, fallen leaves and the branches, diseased leaves, and diseased fruits damaged by pests and diseases should be burned in a concentrated manner to reduce The overwintering base of pests and diseases can be disinfected by spraying the Baume 5 degree lime sulfur mixture carefully one by one.

It provides a way to make more copies of a portion of DNA.
We need to have PCR ingredients that include DNA portion, Buffer solution, Primer+DNA (tap polymerase), and Nucleotides during the preparation step.
In the step of PCR sequence, there are three steps in this section.
Step 1 Denaturation
The addition of heat is needed to separate the two strands of the DNA molecule.
Step 2 Annealing
Temperature, is going to be cool in this step, should allow the primers to bind to the specific segments.
Step 3 DNA Synthesis
To make more copies of the DNA.
Those three steps above keep repeating to make enough copies of the DNA fragments. It is the principle of how PCR machine works.
