What about the drug damage to peach trees?

Peach tree is one of the most common fruit trees in our daily life. Every spring and summer, peach trees are full of scarlet. If there are lots of peach blossom forest, it is a great beauty. However, in the process of planting peach trees, it is necessary to use pesticides to assist the growth of peach trees, but too much medicine will also cause drug damage to peach trees, so what if peach trees produce drug damage?

1. Drug damage to peach trees

In apple, pear, peach, grape and other fruit trees, peach trees have the worst drug resistance and have allergic reactions to a variety of pesticides. In particular, copper and organophosphorus preparations should be careful not to increase the concentration arbitrarily, and it is best to use copper sulfate mixed with zinc sulfate to prevent drug damage. Peach trees will have scorched spots, etiolation and other symptoms after drug damage, so we should take targeted measures to remedy according to the specific drug damage symptoms, and can not be generalized.

Scorched spots and yellowing are two days after administration, the leaves of peach trees soon appear chlorosis or chloasma, and in severe cases, the leaves wither and die. After producing this symptom, you can use a sprayer to spray water, flush the powder from the plant, and then irrigate the peach orchard and discharge it quickly to reduce pesticide residues. After that, quick-acting fertilizer is added to promote the growth of new leaves and make up for the loss caused by poison.

The specific measures to reduce drug damage are generally spraying a large amount of clean water or leaching with slightly alkaline water, rapidly applying fertilizer, spraying drugs to alleviate drug damage, proper drainage and irrigation, removing the parts with serious drug damage, and so on. Corresponding measures can be taken to treat the drug damage according to the severity of the drug damage.

Second, the main points of planting peach trees

The planting period of peach trees should be determined according to local climate, seedling sources and so on. The planting period is suitable, which is beneficial to improve the survival rate of seedlings, shorten the slow seedling period, grow trees quickly and take shape early. After planting, ploughing and loosening the soil and weeding should be done in time. Clear the garden after defoliation, and bury weeds and fallen leaves deep under the tree after spraying to control diseases and insect pests. Early fertilization should be applied to peach trees, especially for trees with too much fruit, and before fruit harvest for late-ripening varieties. In the peach tree before flowering, young fruit stage, fruit expansion period, but also to spray a strong fruit tiling, thicken the fruit pedicel, increase the amount of nutrition transport, in order to form a better taste of the fruit.

The above is some little knowledge about peach planting, when planting peach trees, we should make more observation, early detection and early prevention of peach diseases.
