It is the basic fertilizer for the supply of fruit tree nutrients over a longer period of time. Essentially organic and slow-activated fertilizers are used for the application of base-based fertilizers, which can also be applied in appropriate quantities, depending on the type of fruit tree and the tree phase. When applied to the soil, the base fertilizers are gradually decomposed and constantly supply the constants and trace elements required for fruit trees. The best results are applied as soon as possible after the fertilization of the fruit, with the result that the roots of the tree are still flourishing and the wounds caused by the application of the fertilizers tend to heal easily, and the cutting of some tiny roots can stimulate new roots. Basic fertilizers can increase the nutritional level of trees and the concentration of cell fluids, contributing to the budding and early growth of the following year。
It's time for fruit trees
When fruit trees need to be fatter or absorbent intensity of nutrients increases, the effective nutrients released from the base fertilizer cannot meet the need and must be followed up in a timely manner. The pursuit of fertilizer is both a fertilizer for the current season and for increased production, and a basis for the fruit tree's growth results the following year. The number, number and duration of fats are associated with factors such as age, shape, soil and climate. In general, young trees are less likely to be fatter and, as the results increase, the number of fatters will increase in order to reconcile long trees with results. The normal adult result is that trees are followed up 2 to 4 times a year, depending on the type of fruit tree and orchard。
1. Pre-facing fattening: the budding of fruit trees consumes a great deal of nutrients, and when the nutrient levels of trees are low and nitrogen supplies are insufficient, they tend to lead to a high level of subsequent flowering and affect tree growth. The normal fruit tree period coincides with the peak in nutrient supply and is sensitive to nitrogen fattening, which can only be met by timely pursuit of fertilizer. For weak, old and high-yielding trees, the pursuit of fertilizer should be increased, the buds should be ploughed, the sit-in rate should be increased and the nutrients should be increased. If the tree is strong and the base is abundant, the pre-flower fertilizer should be postponed until the flower is opened. In dry and low-rained areas in the spring, the pursuit of fertilizers must be combined with water to be fully effective。
Following the flower: the flowering is followed by a guillotine period and a period when the fruit tree needs more weight. The rapid growth of young fruit and the acceleration of new growth require more nitrogen nutrition. The pursuit of fattening can stimulate new growth, increase the area of leaves, increase their photocolumn efficiency, facilitate the formation of carbohydrates and proteins, and reduce physiological fallout。
3. Fruit expansion and flowering stratification periods this period of luminous growth began to divide, with some new growth stopped, and the pursuit of fattening could increase the photocolumn of fruit trees, promote nutrient accumulation, increase cell concentrations and contribute to the fattening of fruit and bouquets. This time, the pursuit of fertilizer has ensured both production during the current year and laid the foundation for the next year's results, and has been effective in overcoming the year-to-year outcomes. Some fruit trees have a lumbering period that is the maximum efficiency period for nitrogen fattening, with a marked increase in production following fatting. Large trees with few results or new seed trees that have not yet grown should also be followed up with appropriate quantities of nitrogen fattening, otherwise it is likely to cause secondary growth and affect the fracturing of flowers. Attention is also given to nitrogen, phosphorus and potassium for this period。
4. After-growing fruit: this time, it mainly addressed a large number of problems that resulted in nutrient deficits and flower sprouts. In particular, it is necessary to catch up with late-maturity varieties. Nitrogen compounds in trees are generally found to be at the highest level in august, and in the event of a lack of prior nitrogen fertilizer, the amount of nitrogen in the fall tree is gradually reduced to a minimum before the fall of leaves. As a result, nitrogen fertilization must be pursued later. Appropriate levels of phosphorus and potassium fertilizer improve the quality of fruit and colour effects. This is particularly important for fruit-bearing trees. In actual production, some regions combined the pursuit with the application of base fertilizer。
The periods and frequency of fertilization vary from area to area, depending on the type of fruit tree or the range of the material period。
