Fertilization location grape seedlings generally depending on the size of the tree 30 to 50 cm away from the trunk, the crown can be defined within a ring of water to fertilize as the best range of fertilization, in this ring can also be determined within the application of acupuncture points, radioactive gutters Shi et al. Phosphate fertilizers are better concentrated in the area where the roots are concentrated. The location of fertilization is too close to the plant, which can easily lead to burning seedlings and damaging tree stems. As for the depth of fertilization, it should be in the range of 5 to 40 cm below the surface. The amount of fertilization should be based on the soil, fruit tree growth and other factors to determine the amount of basic fertilizer, top-fertilizer should be considered when dressing fertilizer intervals to determine the amount of fertilizer. The blind amount of fertilization does not result in the premature degeneration of fruit trees, or the loss of fruit trees and fertilizer and artificial waste. The growth of grape seedlings During the growth of grape seedlings, their growth is different. They have strong, leggy, poor growth and even premature aging, and are sick and pest-infested. Should fully consider the seedling growth conditions to determine how to fertilize, apply fertilizer. The different growth conditions of the absorption capacity of nutrients vary widely, sometimes the root system is poor, excessive fertilization will aggravate the damaged roots, resulting in more or less long-term fertilization or even atrophy. Moisture factors Moisture factors include soil moisture, air humidity, precipitation, etc. Soil or leaf nutrients are greatly influenced by water factors, such as affecting fertilizer concentration, release rate of fertilizers, conversion of fertilizers, and loss of fertilizers. and many more. In the case of excessive drought, boron is not easily absorbed, and iron is not easily absorbed when it passes through; when it is applied during the rainy season, the deficiency of the fertilizer tends to exacerbate the loss of fertilizer. Therefore, water is also a factor that affects fertilizer use. Eye Care,Family Eye Care,Precision Eye Care,Complete Eye Care Guangzhou Lingxue Cosmetics Co., Ltd , https://www.lxgj188.com
