Curing old fruit trees is an effective measure to eradicate pests and rejuvenate the tree. This is a good measure. Pests can be reduced by 70% to 80% over the winter, bacteria can be reduced by more than 80%, and the use of drugs can be reduced by 1 or 2 times in the growing season. Save money and increase efficiency. However, there are many problems in the scraping of bark by fruit growers in production. Five improvement measures are now proposed for your reference. First, change early for the night. Most people think that the sooner the scraping is done from leaf to flowering, the better. It is actually wrong, because it takes several months before the leaves fall to flowering. The early scraping of the skin is due to the exposure of young tissue, wind and sun, and loss of moisture. On the other hand, after scraping off the old skin, it is equivalent to people taking off a layer of clothes, and the ability to resist coldness is obviously reduced. Therefore, it is better to scrape the skin before the pests emerge before they sprout. Second, the change is shallow. People need skins on their faces. A considerable number of fruit growers are too deep and heavy to shave, so that fresh and disease-free protection organizations are severely damaged and affect the normal growth of the trees. Therefore, it is appropriate to have just enough to scrape the body and knock off the skin. The trees are white and the trees are green and the disease-free body is not scratched. Third, change the rough to fine. Do not scrape only the main skin, the main branch of the epidermis, for more than one year must observe carefully, do not miss a small tumor, because mung bean size tumors can produce hundreds of millions of colonies, the whole tree scraping Also check it up and down again and again to achieve complete and complete goals. Fourth, change to bring buried. When scraping the skin, pay attention to placing plastic paper or chemical fertilizer bags under the trees, and concentrate on collecting the diseased skin while not taking out or burning out of the orchard, because the bacteria brought to the garden can continue to spread along with the water flow, burning waste of nutrition, It is best to dig more than 30 centimeters deep in the orchard and bury the fallen leaves in the tree. After rot, it is a better nutrient. Fifth, change old to new. After scraping the skin, you should not use Fumei arsenic coating or spray that has been effective, high residue, and highly pathogenic in the past. Use pollution-free biopesticides 5 times or even non-polluting chemically synthesized gum tree, biofilm, etc. The bactericidal protection of the brush spray, especially the gum tree, the biofilm is applied to the tree to form a film, the bacteria is not easy to invade and infect, and the moisture of the tree is not easy to dissipate.
Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients in hydroponics can come from an array of different sources; these can include but are not limited to waste from fish waste, duck manure, or normal nutrients.
